Saw this from powmr

Lol. Nice.
On the one hand, I'd agree with those that say it looks like a lot of work for switching / voltage monitoring. But on the other hand, this kind of setup is usally a one-time deal, setup and leave it to run for a life time....unlike Raspberry or node-red that will require updates, SD card replacements...etc.
To each his own sha.

Setup with Siemens LOGO 8

The PLC takes analog inputs; Panel voltage,controllers
Current and battery voltage as 0-10v .

Panel voltage,controllers Current and battery voltage are converted to 0-10v by voltage and current transmitters, which can be read by PLC.


The Programmable logic controller gives you endless
Process variables ( Solar panel voltage and current, battery voltage, solar panel power production) control while minimising hardwares such as relays, contactors, switches etc. PLC makes changes to Solar set-up easy and flexible as changes are made in the PLC software . PlC are primarily for industrial control but there are relatively cheap PlCs in the market for home automation.

24 x 130k is 3.1m for a 48v 2000ah bank.
Incountry price of 48v 600ah lifepo4 bank is Abt 3m.
40 x 12v 200ah quanta = 48v 2000ah is abt 6m
I would take a 48v 2000ah lead acid bank over 48v 600ah lithuims.

Wish the batts came in 6v 2000ah, would be a lot easier and affordable for a 48v bank owner.
I wonder the price of 2v 1000ah

GeorgeD1 scatter everywhere. This was the calculation i was waiting for

With 5-6 million total Solar panels inverter and wires for a total package. Wow

Many big men dey craze for head when dey still dey wait for nepa and be burning diesel.

This is the way to go

One of their cars among their flet of cars will give them this.

mukhcech:


Thank you Oga mi. It is the rechargeable type with two batteries.

Since your fan is rechargeable, you are good to go. I have the brand new of that particular inverter. Infact, mine is the type that comes with the 20A charging system. You can reach Remi.2good (remove that dot) for a detailed review of the inverter. It works every well for him and i even got it based on recommendations from users like him. But i got a higher inverter now.

I can sell it to you for a price lesser than prevailing market rate, if you are interested

Pls anyone here has the makeskyblue or powmr charge controller for sale. Urgent pls.

And is there any seller in Jos where I can get solar panels urgent too

Good day all. I need advise on Growatt vs Axpert.

I am planning to buy Growatt inverter, but want to know if anyone has had issues with his/hers over the years. Also, do you think Growatt is better than Axpert as being postulated by these foreigners.

Thank you.

What do you mean by "external logging" please? And what are examples of the integration options Axpert has that Growatt does not.

Thanks.

For instance I log my inverter (axpert variant) data on emoncms through an app called solpiplog both of which are external logging, there are other existing scripts that are shared by various individuals/communities just because axpert(or it's variants) are used by quite a number of people . Growatts on the other hand does not seem to me as being popular like the axpert hence am not sure there are existing tools to read data from it but ofcourse I may be wrong.

[Please be more expansive on the bolded, looking for 3kva/24 with editable charge settings, mppt, batteryless function]

Okay I am now looking for a freezer to replace my current 219t which I really loved but I guess it's time to give up on it.

So I am trying to decide between thermocool and LG inverter freezers both are at similar range in terms of price but thermocool is bigger. I know @ceaser got the thermocool inverter freezer sometime ago, has been your experience? Anyone using the LG inverter freezer can also help here.

Inverter freezer 319L rated at 115 watts. I think the equivalent non-inverter 319L is rated at 156 watts (I'm not sure it won't be higher). It comes supplied with wheels which you will install yourself. It starts softly at around 86 watts, slowly ramping up over 15 to 20 minutes or thereabout till it gets to its desired consumption which is determined by the temperature of the contents. Most days when the contents have reached set frozen temperature, it maintains a steady 102 watts to 106 watts. However if and when the contents are freshly put inside, it can reach a freaking 166 watts. But I suspect that is to make it freeze faster and it does freeze fast and keeps item frozen well for 12 hrs (which is the longest I've left it without power) after power outage. Although the manufacturer's spec indicates 100 hours after outage. I also keep the high freeze buttons permanently on on my freezers, otherwise maybe consumption could have been less overall.

I think when it comes to freezers, thermocool gets it right. Their non-inverter 203L that I have had for almost a year has so far kept its cool and it has not disappointed nor has it made me hot with temper, although the door LED light burned out on the 4th month of use and I'm careful with replacing it so as not to install a replacement bulb with crazy consumption. The 203L (rated 115 watts) keeps a constant 110 watts on most days although I suspect that it may be lower when contents are well frozen cos I noticed that the inverter battery drains a lot less overnight when its content are well frozen.

I have read here good reviews about LG inverter refrigerators, so maybe they trump thermocool in the refrigerator landscape. I once read about their proprietary "linear inverter compressor" which performs even better than the regular inverter compressors. I think they use that in their high end refrigerators. You may want to confirm the use of this in their products available in Nigeria before you purchase LG.

ojeysky:


Thanks checked it, but seem not to be using an inverter compressor? However coming from a htf-219t will like something like that or bigger than that as 200has is smaller. That's why am considering a 319iw but I see there is a turbo inverter series as well 319ts.

Which one is turbo inverter again o? Is it different from the regular inverter compressors?

mctfopt:


This is the device that I use which may serve your purpose.

I've ordered this stuff since June but Corona nor gree me get am. I may have to re-order when things get back to normal.

Oshomo12:


Kindly use a 2v cell to achieve this (600~1000ah). Stay away from 12v batteries. They are not designed for this kind of heavy use.

My brother can you elaborate more, it will guide those of us that want to get a bigger bank with heavy use. Pls respond .

Sorry, I'm a novice on this subject matter. When you log data, what does that mean or do? And what's the benefit of the scripts other users share. Thanks.

Wow finally made it here, after reading through almost 23 page since yesterday.

Wow best thread on NL.

This "set and forget" part is why some of us prefer the node-red route. As it happens, things are not always equal. There are days you need to temporarily override your automation. For me, that is a single button from my phone, at home or anywhere in the world.

Abdomox:

What data logging means is getting information from the inverter with a software and then having a software present it in an human readable format such as the one attached. As to scripts, what I meant was that some people share their codes that you can then use on your setup.

That said, I will suggest that you don't worry too much about logging for now, both inverters are good as standalone. I have not used growatts before but the spec I have read are good to the eyes. Perhaps if you indicate the specific axpert and growatt model you send to procure then you may be advised based on spec.

Thanks for the detailed response, as to your question, they are all 319L it's just the model that is different, the TS apparently has a turbo fan attached to the lid to circulate air for distributed cooling. I loved that feature on my current non-inverter 219T until Kazeem fingered it and I lost both the fan and light. Worse part is that I still paid him for all the damages, with my freezer turned to a power guzzler
What was the price like when you got yours though? Prices are not smiling o

ojeysky:
So when I got introduced to Sonoff I was hoping the hub version would work for my household and ordered it, unfortunately based on my house wiring and the various dependencies thereof, the individual Sonoff basic is what will work for me. My AliExpress tracking says the hub is now in naija while the basic pack I ordered is still no where to be found(hoping it will arrive soon as well)

Interested in the hub? You can book it for 22k. It's the R3 version with 8kw+ cumulative capacity. It will come with a remote as well

So the Sonoff CH4 8.8kw capacity with remote controls has arrived and in its original packaging.
Application scenarios:
1. CH1 control you lightens
2. CH2 your pumping machine
3. CH3 Security lights
4. CH4 freezer/fridge
Each of the CH has a 2.2kw load capacity.

Reach me if interested.

earthrealm:


Epsolar 60amps mppt
Morningstar mppt.
Victron mppt.

Fangpusun wch is a chinese victron clone has that capability, but you need a special usb cable to unlock it.
Another option is buy an inverter with equalization option.
Mustpower,sorotec, phocos all have these.

Note these are just the models i can remember now
There are other models with similar capability out there

The bolder indicates that MUSTPOWER has this capability. Does that mean I do not need to use equalizer on the batteries again? Again, is MUSTPOWER different from MUST ?

Holy cow! 197k. That's killing. This stuff was 167k, at most 170,551k less than three months ago.

Don't worry, I can give you a couple reliable outlets with good prices in ADK when you're ready. There was a minor altercation with one of 'em outlets there when they disappointed another client which I knew. They later called me about 6 weeks ago that they now have it in stocks and asked if the guy in ADK will still be interested. So there's still a chance they have it and probably for less than 197k, I want to believe.

I'd have loved the fan type too, but the products I saw with fans were inverter 509L and regular 319 and regular 419L. I almost believed that the 319 inverter had no fan option if not that you posted it here now. If I knew there's 319 inverter turbo option, I'd have insisted on it.

Saw this from powmr

I've also come across rival MakeSkyBlue hybrid and regular inverters and as usual more expensive. I have not seen a batteryless option in their offering.

Clearly PowMr isn't bad, reason I've remained at ease with using their MPPT controller. They keep me away from MakeSkyBlue product which is the same form factor but prohibitively expensive for that product.

Speaking of PowMr MPPT, I may have a new spare for sale. 60amps, 12/24/48 auto. Supports lithium charging.
