For a 2 battery setup you may not stress over an elaborate scheme - the odds are in your favour.

Just make sure that you charge the batteries to full standalone before you put them together in series (assuming you wanted 24v) and then equalize regularly

If you are not locked in yet as per purchases and have no plans to expand by a lot anytime soon, then a 12v inverter is pretty good and takes away all your concerns around battery balance.

One thing that kills tubular batteries quickly is that they need a higher voltage absorb charge than your average basic inverter can provide, if you have solar then this can take care of the problem somewhat.

There are decent MPPTs that will work well for you even at 12v and affordably priced.


TechGeek777:

It's noted boss. The battery will either be 2 * 150ah tubular OR 2 * 200ah tubular.

Considering both batteries, which of the charger brand would you recommend and how many Amp?

Inverter is often the most catastrophic failure point. Once it goes down, you are in the dark. My trick is to always have a spare inverter. About 2 months ago, I was to travel to Abuja and night before the day of my flight, my inverter packed up. A thunderstrike took out the inverter. I had to set up the spare that night or my people will have no reliable electricity till I return.

So, have a backup inverter if your system is critical to you.

My brother backup inverter na money be that oh.

Did you install proctective devices before the thunder struck?

ITS NOT SET IN STONE, there is some flexibility to the equalization thingy.....the 4hrs...the 30 day frequency...all are recommended, but nuthin catastrophic will happen if u don't follow it religiously....just free your mind and try to follow it as best as you could. if u are unable to achieve 4hrs equalization with your solar.....wch is almost impossible..unless you have a n oversized array. if you don't, you can leave the equalization voltage on the CC for 2 to 3 days...so u are sure within that period 1hr here, 30 mins there...the cumulative would be enough to achieve a good level of equalization

If the battery equalize voltage is set to 31v for 24v setup, and am only able to do it for 2 hours on the first day, can I use the battery at night and complete the other two hours the next day, or should I wait until I complete the 4 hours equalization before the should start using the battery?

Sorry for the many questions oh.

That's what it looks like

Hi boss, it appears you are on RE on quite a big scale. It is impressive that a lot can be achieved using RE.

Can I achieve same (I.e. to use this same kind of cooker) using a 12v configuration of 230ah lithium battery bank? If not, what minimum bank and configuration can help me achieve this. I presently use a 12v 400ah lead acid bank connected to a 2200w solar array and controlled by a 60a Poems CC. My current consumption is about 300w. But i am looking to port to lithium very soon.

Kindly suggest a minimum configuration that can enable me power my electric cooker. Thanks sir

The bigger face does about 1.4kw while the smaller face is about 1kw so total is 2.4kw. For a 12v Lifepo4 that will be a major current pull (almost 1C). To use double face cooker I will suggest you either go 24v 230ah or 48v 230ah with the later being the preference. If you do the 48v 230ah you get at least 4hrs of cooking.

Hybrids have more electronics, hence are more sensitive and prone to failures from a variety of factors. Dirty Ac voltage, lightning strikes, poor earthing, current leakage etc.install protective devices and ur hybrids will last a long time.
Also good to hv a smaller back up inverter...just in case,

You ask about Micro inverters , like everyone mentioned the cost and availability is a no in Nigeria.

As for the hybrid inverter, some will give same operations as the micro inverter.
Now it has ironed before in the forum, if you are going for this , it is always good to have a back up , inverter in case the main hybrid is gone for repairs. Like someone suggested that all necessary precautions in protecting your inverter,
In fact both hybrid and standalone inverters.

Nice one, thank you

Thank you very much for this advise. I imagine that 48v configuration will require that I get 16units of the 230ah cells, right?

Also, in light of your advise, do I need to make a significant increase to my solar array and charge controller? I definitely know I need to get a 48v inverter.

PS: Is there anything like a 36v configuration?

Yes you will need 16units, note that the estimates are on the assumption that you dedicated the battery bank to cooking while maintaining your 300w or lower load.

Using a 3x generation principle, a 4 to 5kw array should charge a 230ah 48v from low to full daily (subject to sun availability). If you've not gotten inverter yet then you can do hybrid inverter instead.

Yes you can do 36v battery bank especially if you are on DIY, the problem will be getting a 36v inverter or charger

Yes, Even the 300w is a maximum. It most mostly less. Also, we do an average of 2hours cooking per day. We most stock in the freezer. But it think it is best we work with the maximum/extreme possibility

Using a 3x generation principle, a 4 to 5kw array should charge a 230ah 48v from low to full daily (subject to sun availability). If you've not gotten inverter yet then you can do hybrid inverter instead.

Nice. How does a 5kw translate in terms of watts of the solar panels? Does it 5000w (possibly 500w X 10 units). If yes, that will be an overkill as I doubt i have enough roof space to them all. Yes, I will consider hybrid inverter option. Been reading up about it lately.

Re: Solar Energy, A Complement To FTA by durodee(m): 2:44am On Aug 25, 2022
I will just like to point out that you will need about 3.5m to set this up ( batteries 1.4m, panels 1.2m, CC 240k, inverter 400k, accessories 260k) and if it's only for 2hours cooking per day , then it's not cost effective. RE outlay costs do not favour heavy users that need to factor in robust setups.
Unless you have specific reasons against gas cooker setup, that will be a better economic cost than RE for the scenario mentioned.

Your setup is simple boss - you do not want to complicate things too much.

If you choose to go with a 24v inverter, find a means (12v charger) to charge each of your two batteries individually and fully and even equalize them if possible first time around and before you put them together in series. Once you have done this step once then you can be equalizing (at 24v nominal) once every 30 days or so. You will not need to disconnect or separate the batteries at all.

If you choose a 12v inverter, that makes things even simpler and more stable, if your 12v inverter or charger or charge controller is capable of getting the batteries to equalization voltage, you will see extreme longevity from the batteries significantly better than in a 24v setup and much simpler maintenance.

I strongly support this point by Oga Niyi.

Though, it might be a bit expensive at the beginning especially with the ongoing transition to Lithium, a good 12v AGM/Gel/Flooded charger is essential for the general maintenance of your batteries. It's highly recommended (especially buying brand new) for those who are about to install a new inverter and batteries to charge their full before installation. Some batteries come in a low state of charge and a good charge by the 12v charger to the batteries specs and allowing it to float for 24hrs before connecting is a good practice that will save you anguish in the future.
