Unless those borehole people come n dig it up. Dem bury the whole tin. The only cable I see is that of the one control box.

sintolord:
2.2kw is high for a 1.5hp. Check your cables if it is properly sized. Better still, you can over size to compensate for high ambient temperature when in use in the afternoon. Also check for corrosion at the point where cables were joined together. This issue with this is, the point where the cables where joined, will be in the borehole.

U need to av 1.5hp submersible to know aw much power they consume.
Cause 1.5hp dey consume around 2kw for normal light n I'm sure it will b Abit higher for inverter.

Oshomo12:
Pls clarify this statement, I don't understand it, thank you.

Note: 1hp is 750 w. so 1.5hp should be 1,125 w.

It's the way the inverter is. I added the extra fan cause the body get warm but d inverter fan will not start up until there's 50% or more load on it. If this should continue. It won't last long before parts start failing.
Fan should b controlled by temperature not by certain percentage of load

AC input has switch(MCB), u can always put it on n off

I'll ask

TechGeek777:
Was the defect on the inverter before you purchased it?
The bigger fan you bought is it serving as a cooking device to the inverter?

If NEPA and Solar are both available at same time, is there a way to isolate NEPA and charge with Solar ONLY (either by means of breaker/change over)?

Can you confirm the 5kva 48v from your source?

3.5kv is same as 2.8kw in most inverter u will see out there in d market
Kw=kva*pf
Pf of 0.8
I thought the op mentioned 3.5kva n not 3.5kw

ojeysky:
I get the point but I don't get why you believe a 3.5kw will be 2.8kw in practice especially if it's just to handle short load. I know axpert variants users here who have put over 90% load on their inverter without any issues and when I used axpert I had similar experience.

In the case of my 1hp apart from the starting surge it consumes less than 1kw. A 1.5hp outside the surge(which should not be more than 2.5kw) should consume 1.5kw or less. Note that the guy is asking about a 3.5kw inverter not 3kw... ofcourse if he has money he should feel free to get even 8kw

Still working 5n. There is a little defect in the design which I worked something to it. The fan doesn't come on unless the load on it is up to 50%. Iron will b running on it for 30mins n fan won't come on. I bought bigger fan n fixed it on the other side with a switch, so I put it on b4 I put on my iron.

Absolutely, its always on even wen I'm not at home, with freezer on it. I can count d number of times I put it off.

Ac charging parameters are adjustable, it's not an hybrid inverter, d only charging option is AC, charge controller handles the solar charging.

I no of 3.5kva 24v, don't know if there is a 48v variant.

TechGeek777:
Hello bro,

1. How is your "Crown Ricco" inverter doing, has it develop any fault since 9 months you have been using it?

2. Would you still recommend it?

3. Can one use it to set the battery to charge from NEPA only or from Solar only?

4. Do you know how much 5kva 48v would cost for Crown Ricco?

Powmr mppt sold for 61k here. If that is cheap enough for ur budget.

incogni2o:
Can anyone recommend a good quality and cheap charge controller?

Also, I don't see people speak much about performance of LifePo4 batteries, any testimonies of any specific brand?

I'm not sure u get wat d first guy is driving at
1. 3.5kva he's talking about is most likely 2.8kw in few cases it might b higher or lower than the above figure
2. 1.5hp is not 1hp
3. Ofcourse 1hp should do fine with 3kw inverter, as it requires around 1.2-1.5kw of energy.
It's best if e can go bigger. So as not to waste money

ojeysky:
I used my 3kw GK series MPP hybrid inverter to power my 1hp pump comfortably with all other loads powered on, so am pretty sure 1.5hp won't die on it

Can the powmr go for 35k boss?

obinna37:

It couldn't b yes if
1. If ur battery is lifepo4 of 3kwh up
2. If ur panel is 4kw up n u can pump wen the sun is up, even wen d sun goes down ur panel should still generate up to 1.6-2kw while the remaining 700/300w will taken from ur lead acid batteries.
And most importantly, ur 3.5kva inverter must b those variant with toroidal transformer, they handle surge better, if ure using a high frequency inverter, don't pump

oloet:
Does this answer cover using 1600watts solar panel with it?

Straight answer... No

osayuwamwen:
Can 3.5kva and 2 220ah battery power a 1.5hpower submersible pump?

We can't say accessories n logistics is expensive.
But that MCBs ehn, of all the people wey don dey call me that their system get this error and that. I have not seen 1 MCB wey b known name.
1 even use AC MCB for panels, some don't even use MCB n SPD at all. We know aw expensive Schneider is, some1 here mentioned getting 1 for 23k thereabout, can't remember d amount, but Dem dey sell cheap ones for alaba (3-4k) wey dey carry various names, u go see some wey Dem put Schneider ontop sef. I no this cause av bought 1 b4.
The recent system I checked had Schneider DC MCB connect with d panel, MCB got burnt n didn't even flip. Charge controller didn't spoil.
Since list of all items dey, buy better items, not leave everything to installer hand.

zeestone99:
How is Accessories, MCB and logistics inflated. Shey you will go and buy it for him.

This morning for ibadan

JUO:
please check the price again as at this morning. E go shock you

It been a while I bought DC cables in alaba, but I no they are Abit cheaper compared to prices of ogunpa here in Ibadan. They sell 10mm 2k per yard here.

JUO:
tell him the price for jinko 400w and see him run away. Check respond above. One said 6mm² at 2k per yard is inflated and he doesn't know distance too, 20k logistics is inflated in alaba. They just sit down and type

Incase u see better seller for grade b, kindly let me know. I need 16 pieces.

isangjohnson:
Amy Wan is very active and very fast in responding to messages but most of her cells are Grade A.
I wanted 304Ah Grade B and Awan doesn't have it.

Zeestone has all of these. U can buy from him
Hope you have not bought these panels. Buy yingli instead, them get 400w and the performance is decent, make dey no go sell 300w wey no go produce more than 150w for u.

benefitzte:
At the bolded, am a newbie here please
My question is if I decide to go with what d installer quoted would I be fine? Or should I go with d Nova quotation?
NB: Nova sale 300W mono panels for 75k

Novel solar prices are inflated. 200w panel a friend got from them for January was 80k. Dey don't make any of these items or even couple them, dey import and print their name of it. Dem get warranty sha. Maybe nah why their prices dey go up anyhow. As per ur inverter, if u Neva buy, look elsewhere, if u don't abuse ur inverter, n u secure am with AC&DC MCB&SPD n earth all component(panels included) n add stab if u will b charging with NEPA, ur inverter go last Wella.

I bought a 60A charge controller

Hello gurus in the house, above are some of the features of d Novel hybrid 2.5kva 24v that I just purchased. My installer is quoting the following accessories
DC surge protector= 13k
60A PWM = 25k

Whereas @ Novel Solar they are quoting the following
DC surge protector= 35k
Input and Output protection= 40k

My question is which of these questions should I go for considering the features of the inverter that I stated above.
It's 300W x 4 panels

This quotation is questionable
1. Why not put the make of d battery there. Make e no go b those starplus of 145/150k variant e go buy for u
2. Wat kind of inverter is he buying. Make u no go buy inverter wey surge go spoil in no time.
Better transformer based inverter with 30a AC charger is also sold for 85k
3. With the kind of charge controller will he be using, there will b some energy waste cause he go parallel those panels, your best is to buy 190/180w with 8/9amps which new 1 is 45k. U can buy 4 of this.
Make sure he doesn't cut off the connector, make e buy branch connector, cause e no put am 4 d list.
Price of charge controller is ok. 40a pwm I suppose.
Every other tin is cool just make sure those breakers are properly sized.
2 DC breakers (32a for panel and battery)
1 AC breaker (order 4a variant on AliExpress as it's difficult to get this here. Lowest av seen is 10a which is too big for ur setup)

U need 8 pieces of them for a 24v 2.5kva inverter, message valto for price

Nicols:
Stil trying to understand this lifepo4 ba3. How much can I get a lifepo4 that can match up with 2.5kva inverter?

That's d recommended discharge per hr. They charge faster though, most likely 40-60a/hr charging current.

ojeysky:
1/20 which gives you 0.05 and then you multiply that by the battery capacity which is 11A. I would have followed this up with a few lithium campaign but make I no talk

Valto

zinodizt:
Can you recommend any vendor here for that?

There is no info on d charging current. It only state that u should discharge d 220a in 20hrs. That's 11a/h

osayuwamwen:
Pls what is the maximum charging current of this luminous 220ah battery, the battery information is written on the picture below

If u av d money, go for lifepo4

zinodizt:
I have two 250w solar panels and 1kva inverter and a battery but the battery is currently bad and I am planning on replacing the battery. Which Battery would be recommended as I am using just one I am looking for a strong battery and moreso can I add a panel to the setup...

1. Wat kind of panels, can u snap d nameplate
2. Were dey connected in series or parallel.
3. Where are d panels facing
4. Y did u decide to go for Felicity battery, u could av gone with coupled cells if u read through their reviews on this thread.

emmy9500:
Finally installed my solar system, thanks to all the information in this group

I have a question, I have 3 panel rated 380W but my charge controller only read 340-400W the installer said it would have been higher if I used 200W panel, I am planning to add another 380W solar…. I just want to ask if the reading from the charge controller is normal

The battery can fast charge I guess. But the discharge was rate was clearly stated 0.1c

ojeysky:
Well it also means 95A and below is fine. That said using the recommended 65A that is almost 0.3C. Seem high for a lead acid that wants to last long

I think wat that means is 95a n above will damage d battery. Safe charging amps is 35-65a as written on the battery.

ojeysky:
The charge current text on the battery is blur can you indicate what is written there as it seem maximum is 95A which is quite strange to me for a lead acid

This discharge rating is quite low. It's states 200a discharge is 20hrs that's 0.1c or 10% of the capacity in 1hr. Probably that's just a paper something. Cause batteries like fullriver should be able to handle atleast 30% or 0.3c eg a discharge of 60a of dat 200a in 1 hr. It's not like I av fullriver batteries but I av 2 quanta SLA n dey do 30% of capacity discharge. Well. It best you stick to wat u av on the battery. So as not to kill it b4 it time

Milito:
What is C rating please?

Any clue from the attached pic?

You will need 2 of those if your panel is above1400w

emmy9500:
Is this type of charge controller suitable to charge a 5kw/24V lithium battery

Since u can't open the inverter yourself. It's advisable you take it to inverter repair center. N one of your battery is bad already. My guess is you don't do 50% DOD.

Eazeee:
Good day solar gurus. Please i noticed of recent that my solar battery (two 12v200AH) after showing fully charged at 100% will suddenly start dropping down to around 70% by evening even when the solar system is off. As such, it doesn't last whenever I start using it. Please what could be the problem? I am using a 2000va/24v smarten inverter. The batteries are not up to a year & it was serving me very well before now. I also noticed the small fan at the back of the inverter is not turning & it also shows Mains not available

There are lots of videos on YouTube you need to watch and articles u need to read for you to understand things.
V-volt
A- amp
Ah- ah
W- watt
Wh- wh
U see those LA battery u dey see 200ah. It's 200a. Dey are not 200ah. 200ah means d battery can do 200a in 1 hr. Check basic electricity videos on YouTube. Read article on electricity and DC applications. All these will b made clear

ojtech8291:
I don't understand what you are stating here as a unit of battery. Unit of battery is AH. When you multiply V by AH you have VAH. Note that VA= W, so you have WH, When in 1000 up wards it becomes KWH for battery. Without the H there you are still not referring to battery.

Yes you can. But if ur choice of battery is a 12v Lead acid, don't do more than d c rating inside d batteries manual or on d body. If your going for lifepo4. Ur battery can safely go as high as 1c. But that doesn't mean you should load ur inverter pass 60-70% of it's actual capacity. U will break it in no time.

Milito:
Hello gurus,

Is it okay to use 4units of 200ah batteries with a 7.5KVA inverter?

Works on most phone. We get Tecno, Infinix, Redmi n Samsung here. N it works on all. If d one on playstore no work download from their website.

isangjohnson:
What type of Android phone will work with this App Sir?
From what I've noticed, not all Android phone work with it because it doesn't work with Tecno pova. Download and open for the first time and refuse to open subsequently unless I uninstall and install again.

W=V*A
12v*220a=10,560w or 10.56kw
Note that cause u physical have 4 12v batteries doesn't mean you have 10kwh as most lead acid is rated 0.3-0.6c which means ur 10kw battery can safely pull 3-6kwh out of the 10kw you have on ground.
Kw- kilowatt
Kwh- kilowatt hour

Milito:
Please how is this calculated?
