True value 24v/100 ah battery pack will cost how much?

Just the finished pack alone, excluding the inverter and those other whistles.

Using an offline, third party shipper may reduce your price significantly.

I am currently trying to negotiate for a 1.5kw (3kw surge) pure sine wave inverter with charger for around $105 from an AE seller but offline.. Their shipping is about $60 but I have a shipper that may be able to land it for not more than $20-$30 max....available inverters in Nigeria for same capacity is from 70k and above.

My only fear now is reliability...i dont intend to abuse or over load it so i am hoping it should serve me for a while before it packs up.

That third party thingy is still somehow to me sha. I don't know how effective it is especially with the terrible reviews I heard of "shoptomydoor" which one would expect to be a model to assess the viability of third party shippers. In fact I was already registered on their website but I had to begun to divert their mails from my inbox to trash.

Hello sir I was banned on the solar thread for reasons unknown but I didn't understand your last mention to me.
Do you mean you want 2 units of the mppt charge controllers?

Nope. I posted that two units of the CCs I ordered for has arrived Nigeria.

Sorry for that overzealous bot

I appreciate your very quick and apt response. Thank you very much.

Specifically, my tv is a scanfrost 32" tv of 56watts. If the option you stated above is not so expensive I will gladly embrace otherwise, I am thinking that I can convert a laptop adapter to power the tv by jettisoning the two ends(plugs) of the adapter and connect to source directly.

In any case, kindly advise on the best, possible and appropriate direction.

Thanks a bunch.

Your Scanfrost is strictly AC powered with the power board/pack built into the unit, so you can't use it directly with DC. You'll instead need an inverter plugged into the DC source.

The TVs that are DC powered usually have a DC input port at the back. The port is where you plug in the external power pack (similar to how it works on a laptop) and it's also the point you can plug in your modded DC plug. Your Scanfrost has only AC port, not DC port.

See attached picture.

@ bolded. Does it use battery as secondary power? If yes, you might need to replace the batteries as it may be messing with the memory and stuff.

My wattmeter had a slot for button batteries, but I never used it for once until about 3 weeks ago when it started acting up. It beeps when plugged into the mains and all the elements on the display show up all at once, haphazardly, making reading any meaningful information difficult.

So I decided to put the battery slot to use, it took 2 button batteries in series. The problem has not repeated itself since then.

backfrom another unwarranted ban.

so went inverter fridge hunting today, zeroed in on 2 , Considering LG again. the sellers werent knowledgabel aout the consumption of the fridge, and the sticker on 1 says 1.5amps , which appears too high. need to go back with a meter, for a final decision.
anybody using samsung or scanfrost inverter fridge?

and now my watt meter of over 3 yrs has packed up, it displayed voltage and frequency, but refuses to read watts, opened it up, didnt see anything amiss. anybody experienced this b4?
. my clamp meter also is bad, got bad 3 months ago, and covid 19, hasnt let me buy another one yet.
i wonder why 2 of them decided to pack up same time

Easylearner:
My inverter just got toast(burnt)from thunder... no surge protector.

I'm planning to fix the inverter and install surge protector...

What is the best way to install surge protector :

Between the Charge Controller and panel
Between the inverter Ac output and house load
Between the inverter Ac input (to charge the battery) and Nepa...

Please I would need your advice.

I believe this post by NiyiOmolyunade addresses some part of your inquiry.

NiyiOmoIyunade:
I am afraid your bad experience is very likely due to poor or inadequate earthing/lightning protection at your location - it is best if you fix this first before purchasing a new inverter as even a premium inverter would fail if it took a lightning hit.

You stated that the inverter was charging the battery from the mains during a heavy thunderstorm - lightning as you know hits power transmission lines pretty often and this could easily be carried through the line to your house equipment.

A suitable earthing system and LPS coupled with an SPD to take the hit/heat away from your inverter and household equipment is the way to go.

By the way, I don't know how feasible a repair of the inverter might be. Except the company offers to replace the board, any other repairs by some random electronic/inverter technician may just be like wasting time.

If it's not so much, have you considered getting a new unit?

DHL has a habit of asking for extra fees at point of pickup

Oh, well the courier guy that called me did not mention that I will be paying an extra fee. He was actually on his way to my address before I told him that I will be unavailable for receipt. Also I did not receive any text message from DHL to that effect. This is in contrast to my experience with UPS. They notify me thru SMS and also send the invoice to my email for me to pay up. They confirm receipt of my payment and proceed with the final delivery.

According to tracking, the item went thru customs though but I'm optimistic that I'll likely not be charged since it wasn't mentioned by the courier guy. The only other reason I could be charged is if it enters demurrage. But between today and Monday is not up to a week to include demurrage in my opinion.

Hello house. Pls I need help. I will like to use My 32" Led tv on my soon-to-setup Solar/DC system. My question is that is it possible for AC tv to run on DC? If so what do I need to get/do?. Thanks in anticipation of urgent response(s)

An AC TV can not directly run on DC source. They are however 19 inches to 32 inches TV that has the power pack external like in a laptop. In those, you can jettison the power pack and use a DC cable to connect them directly to your DC source (usually 12vdc, 15vdc or 19vdc) depending on the size of the TV.

On the flip side, if you still wanna go with your AC TV, then you will require a DC to AC inverter to be plugged into your DC source to serve the TV.

If your TV does not consume so much power, there are small form factor inverters the size of cigarette lighters than you can co-opt to power your TV. If you intend to plug more AC devices along with the TV, then you will require bigger inverters.

Good day o my people. Pls is Aliexpress same as Alibaba?

I want to try order an item from Alibaba I don't know if iam making right decision ?

And more so I heard no importation now because of covid, is that correct ? Pls guide me through because this is my first time of ordering from them and I know practically nothing about it. Thanks.

AliExpress is for retailers. You can buy minimum of one quantity of a product to several quantities. However being retail, it's usually of higher price than Alibaba.

Alibaba is strictly wholesale. If you are those that buy items in containers, Alibaba is for you. The sellers there sell their products on MOQ (minimum order quantity) that you must meet for them to consider selling to you.

Some sellers on Alibaba can ship to you one unit as test sample, even for free. However some Nigerians have been found out to misuse that opportunity. They go to different sellers and get samples of the same item for free with false promises of coming back to buy in wholesale. If you visit 100 sellers of the same product with each offering you free samples, you can tell the money to be made selling that. As a result, most sellers seem uncomfortable with giving out free samples.

Out of the recent orders I've made in the past two weeks, I decided to use DHL with one that is most important and of course exoensive. There were also options for AESS, Singapore, FedEx. The DHL option cost an extra 11k.

Shipped on the 2nd of this month, I was called today to expect the courier guy at my delivery address. Unfortunately I'm not around, I hope to pick it up at the DHL office next week.

The other orders, mostly on 4px are stuck at "hand over to airline". One on Cainiao is progressing albeit slowly.

I'm now reviewing my cart to see items that can be moved to DHL with minimal charges. I think I can live with something less than 10k increase in shipping fees for items of 30k upwards.

Between a dedicated Felicity Solar Freezer and a thermocool freezer used on an inverter, what would you guys suggest one goes for?

Actually I'm beginning to see the futility in DC solar freezer, I may be wrong though.

Usually for the DC freezers, they'll recommend 2 units 200Ah battery and around 600 watts panel for the 24hrs function to be guaranteed. Whereas size for size for the Hiaer Thermocool 40% energy saving series, with the same set up, you will likely get the same backup time if not less. Of course the conversion efficiency loss associated with inverter is still there but that's nonetheless.

Now the inverter AC freezers is on a different level. It appears that in consumption, it will trump any DC solar freezers size for size anytime anyday.

The ultimate advantage of the DC solar freezer, it seems, is the fact that you won't not to acquire an inverter.

NB: I have not had real life experiences with DC solar freezers to be emphatic about this, so my opinion of it is at best anecdotal, but at least I can vouch for that of 40% energy saving series of the Haier and hopefully by next week I should be able to have adequate UX information on their inverter freezers.

Differing opinions from experienced users of DC freezers are seriously welcomed.

Hi I'm not a tech guy
I only ordered these from CHN based on professionals recommendation, I intend using one myself and selling out the other two.







Btw... One 1 unit left

In fact, I've been called to pick up the two units that's arrived. Hope to be around next week to receive it.

HURRY! PROMO PRICE!!

Axpert 3kva 24v solar/hybrid pure sinewave LCD wall mount inverter with inbuilt 80a combined AC (30a) & solar (50a) charge current .

Is the in-built SCC MPPT or PWM?

Edited: I see that Ojeysky having like mind, has asked the same question.

adrusa:
Does PowMr or Makeskyblue have computer communications of any kind? Modbus, serial etc? Some of us needs to find ways to get the data out. Thanks

Neither has coms of any sort.

However Version 119 of MakeSkyBlue has WiFi hardware so that you can connect your phone to it. I doubt it has remote monitoring capabilities, so you have to be within the WiFi range to use the phone app.

I even doubt if the app is available in the play store. It seems you have to do a side instal from a mediafire link.

mahkanjuh:
I chatted with the ceepro guy, and he told me the 300litre Haier Thermocool is energy saving(Inverter) freezer, coz I told him my freezer is 110w (198L) and he adviced that one use the 1000w for a freezer that is not inverter type of which he said he doesn't have the stock presently

The surge current is the major difference in the two scenarios. Your 110w (198L) 40% energy saving Thermocool I suppose, is truly energy saving compared to the previous regular freezers of yore. But the reason you can't use it with the 600 watts inverter is that it has a momentary start surge which may be as high as 1.2kva.

In case of the inverter freezer, it slowly ramps up the speed of the compressor to a set point (like when you slowly accelerates a car to your desired speed). So the surge current is absent. After a while of working, the consumption also drops as the desired temperature is attained (similar to the way your car fuel consumption somewhat reduces when you maintain a constant speed on an expressway).

SirBunky85:
it's also same Yoruba dat saved gej wen Turai and the cabal wanted to turn gej to a slave in aso rock .the yorubas stood firm for him and evn forced the national assembly to adopt "the doctrine of necessity"and transfered power from yar'adua to him-gej.

That individual you qioted is a rabble rouser. I believe he is best ignored. Resorting to name calling when he realized his folly, he's been ignored.

Tranquillity360:
If it was GEJ,by now all yorubas and their professor would have be on the street protesting.

You are so mischievous, wicked and hate-driven.

The same Yoruba and their professors that ensured GEJ as the vice president was duly sworn in as the president at his principal's (Yar'adua's) demise when the kitchen cabinet had taken him ransom.

You remember the "doctrine of necessity" right? Except you are just a 12 year old which your post actually suggests.

I suspect that this is all a script APC is playing and aimed at giving him a clean slate ahead of the elections.

The court will acquit him and declare him innocent of the allegations. This will truncate any plans by the opposition to tag him a felon when and after he wins.

This government cannot be trusted at all. They get the worst of the people to occupy positions of power.

China makes it a point of duty to put the best of their people in positions of power, duly endorsed by the people who must have had experiences with the candidate over several years and at different fora and will determine if they are comfortable with his character over those periods. Then they can decide to elect him into position. What this means is that you must have led the people in varying capacity (street head, town leader, provincial head etc) one after the other and proven your worth and loyalty to the people at these various stages and the people will therefore determine your eligibility for the next stage.

Lol. How is the PV doing? Good to see my fellow from the green side here

I was well within the Voc limit of the CC. It was the amps rating that I exceed.

I tried to use the Powmr CC to transfer energy from a 60V, 520AH Lithium battery to charge a 24V, 200AH Lithium battery expecting the CC to self limit the charging current to the rated 60A. It didn't. Due to the low internal resistance of both Lithium batteries, the charging current spiked beyond the ability of the CC and out comes the magic smoke. I didn't get to see how high the current went before the smoke but it was less than two minute after I started the process.

Mind you, I have always done same with Midnight Classic CCs.

@Bolded. Sincerely I can't argue . There are reason it's premium.

earthrealm:
LOLZ, i tot i was the king of cheap simple functional installs, you sire is the undisputed king. 5 powmr/makeskyblue 60amps mppt is not upto the price of 1 Morning star 60amps mppt CC with all the bell & whistles

so now you see why I can afford to "waste the life" of a PowMr, though it serves well, to experiment.

If I try that with those top premium, I may incure the wrath of the Father for wasting something that's so expensive when there are people that are still struggling with PWM.

Yet to get the mail...
I need a basic set up in lieu of Lumos... To power TV, decoder, light and fan

I am considering 200ah 12v battery, 12v1kva inverter, 2(150w) panels , charge controller? ...saw your neighbourhood testimonies and needed recommendations

With your 200ah battery, you might wanna consider 4 pcs 150w panel or at worst 3 pcs for a basic install that is limited to TV, decoder, light and fan. But you also need to audit your current appliances to determine if they are energy saving ones that will make you to enjoy your set up more.

Are you planning to go the route of MPPT Charge controller, considering your future expansion aspiration with the inclusion of 140w chest freezer.

An MPPT will create the flexibility of adding more 150w panels since you plan to start with that. Also you may only be able to run your freezer during daytime as 200A may not provide sufficient backup for the freezer.

A 60A MPPT should be okay.

Its one of those pre-made electrical cabinets readily available from the industrial electrical stores. Typically the stores have someone working with them or that they can refer you to make the necessary cutouts. Nothing too fancy needed, drilling machine, Dremel Saw & Hand file. This was one done at Alaba, from my experience with them, I just send a diagram, put a call across and explain & they're able to figure it out from there.
Fans are not temperature controlled (yet), and currently have a manual switch I can toggle as needed.
I'd be making a few purchases for sensors and smart stuff to integrate as time goes on.

How much did the cabinet cost?

jboixxx:
[color=#0000ff]Bros, the issue here is about avoiding SGP which I'm saying it's not possible if you use AliExpress Standard Shipping. If you chose Singapore Post (standalone), you'll experience this same delay. If you pick AliExpress Standard Shipping, most sellers will use SGP (under AliExpress Standard Shipping) cuz it's generated by system. You should note that AliExpress Standard Shipping could mean CPRAM, SGP, Yanwen Registered, Turkish Post etc. And SGP is still same with SGP under AliExpress Standard Shipping, only difference is during logistics dispute.

The delay most of us are experiencing affects only orders shipped using SGP, others are not affected. I did 'receive' an order within 15days last month and it was not shipped using SGP; the seller actually changed it from SGP (standalone) to another method for me.

So, whether you choose AliExpress Standard Shipping (with SGP) or SGP as standalone, delayed arrival is 90% certain. [/color]

Okay. So the extra money on AESS is like an assurance for dispute resolution for the customer, it seems.

Unfortunately 3 orders I placed under SG post two weeks ago has gotten stuck in "handed over to airline" while another I deliberately chose DHL for is still progressing.

Namzy:
I'm confused. There's no way panel array connected to different mppt cc will cause problems so far you didn't exceed the Voc and current. Unless you are saying you can't configure the absorption and float for each or one of the CC. The only problem I encounter with my fangpusun is during equalization as my inverter shuts down when battery voltage gets to 31v

He exceeded the VoC of the ipowerplus in his own case, hence the misbehaviour.

litaninja:
Over the course of the weekend, installed my setup working with an installer and justcallmenuel supplying batteries.
6 x 250W Jinko Poly Panels
1 MPP Solar 3024GK
2 x Venus 200AH Batteries
Breakers, the standard Nigeria inverter knife switch , etc.

So far, looking good.

ToDo:
- Shift those batteries small...the way they are bent is bending my brain.
- Setup monitoring either via an ESP32 wireless board or RPi
- Integrate monitoring with HomeAssistant running on another RPi

Big ups to the forum for keeping this going for about a decade now...

Lovely. Did you have a metal fabricator do that enclosure? I bet not the roadside ones cos they won't understand that diagram you put up there.

Are the extra fans temperature controlled or perpetually working?

essegis:
Ceasar, are you saying the 118 version can be upgraded to have WiFi? Cos I am eyeing the 119 version of MakeSkyBlue only cos of the WiFi functionality. So make I just bone and go for the 118?

@ Bolded. My error, I meant to say v119. The v119 has WiFi hardware in-built but the v118 does not. However v118 is readily upgradable to v119 using some dongle that you have to purchase from them too. The upgraded v118 will lack WiFi features.

essegis:
Also, do I need a special tool for set up to charge Lithium with these MakeSkyBlue? Make I know so I can order once with them oo. Victron and ePever I have I had to purchase external tools for link up. Now I'm looking for a 3.81-4p connector to make the ePever link up after purchasing the Bluetooth dongle.

It supports lithium charging out of the box. In the setting you will select "D01" which is the setting parameter for lithium which automatically puts the boost, charge and float voltages at 14.5v. You may have to edit the 14.5v to something like 14.1v though cos I noticed that with the 14.5v my BMS overcharge protect trips off at 14.4v. You may also have to increase the LVD value to 12v from the 10v default.

essegis:
Thats a split phase inverter I think.

Yep.

Thanks so much boss
Please, can this 1kva power a freezer of 110w?

I never used this for a freezer for once, I only used it for basic electronics like TV, decoder and charging most which did not exceed 200 wards at any one time.

It may be able to power an inverter freezer since the initial surge is absent with those but rather slowly the condenser ramps up power to full speed.

For the regular freezers, it may be able to power the continuous draw, but it may have some challenge handling the surge which may be 5 times that declared 100 watts, but it's not absolute o. In fact I once had one cheap 1200 watts pure sine that only powers a 115 watts freezer on the 4th attempt each time I try to plug in the freezer. The earlier attempts, the overcurrent protection kicks in up till about a fifth attempt when the freezer now works.

I guess those previous attempts already primed the freezer condenser already so that a fifth start attempt will not draw as much current as the first.

A 12v 1.5kva will likely do it for you.
