Charge rate should be 10% + about 2.5% of battery amperage, so a good 40amp MPPT charge controller.
Three 150 watts solar panels minimum depending on how much ah you use daily.

Presently my solar charge controller is 20ah pwm and I have 4 pieces of 150 watts panel. My battery bank is 400 ah. My question is this: is my charge controller undersize?

My installer told me that I only need a 30ah solar charge controller when I am operating on a 3.5kva inverter system which is bigger compared to my present 1.5 kva inverter. I need more clarification on this pls.

Charge controller size is determined by battery size, it does not have anything to do with inverter size.

Hello sir, how can i know the difference between car battery and inverter battery from it's label? Thanks

Ceejay80s provided a perfect answer.
In addition to that, the terminals of deep cycle batteries are usually different from that of car batteries.

Yea, Ceejay80s utterly dissected the question. Meanwhile, what is the major difference between their terminals? also, whats the umbrella name of car batteries?

You can order online @,a 1500va car inverter goes for 9k in konga 12volt input,220volt ac ouput,820watts,try 9ja style cut the cigeratte plug and connect to ur battery

oga festus,
Will like to know if you have used or have any experience with any of those 9k inverters on konga ?

timifakay:

YES

Charge controller size is determined by battery size, it does not have anything to do with inverter size.

That being the case, my battery bank is 400 ah in total. What size of charge controller will be okay for my battery if my panel rating is a total of 600 watts?

Just a friend of my bought it from jumia last two months it came with 6month warranty and working fine he used it with car battery and it last longer.....bcus it consumes less current from the battery,it has a cooling fan and it does not have an inbuilt charger planing to get one soon....

Car batteries have fixed terminals like we have always seen from time immemorial, deep cycle could have hole or bolt.
Lead acid battery is you only thing you will see on car batteries, inverter batteries will have additional labels, check ceejay80s' post on it again.

I answered this since the first time you asked and reply remains the same- 40amp. Here: www.nairaland.com/2428983/how-create-locally-made-inverter/59#45924182

can I mix match batteries of different capacities
i.e. 40a batteries with 100a batteries
in series or in parallel

You can, but it is not advisable. Always pair same battery type, capacity and of same manufacturer if possible.

U can in parallel but not in series, though I read on line that u should only connect batteries of same manufacturer , age and capacity together both in series and parallel , but all my batteries are in parallel.

12v 18ah (2) used

12v 40ah (3) used

12v 100ah (1) brand new

All in parallel and its working perfectly fine for me, sometimes practical dey better pass theory,

But connecting a 40ah battery and 100ah in series is not good o and if u are connecting in parallel, make sure all the batteries are in good condition

gurus I don come again o

I have 2 40a batteries, 2 7a batteries right now
I am thinking of getting 2 100a batteries now.

I have a 650va ups 12volts and a 1.5kva ups at 24volts.

which of these ups will give me the best performance

since my 650va is able to match my load, is there any sense in using the 1.5kva ups

thanks in advance.

30amps smart battery charger for sale, used for about a month, working perfectly, comes with the carton and manual.. also a WELLSEE 30amps PWM solar charger controller for sale at an affordable price. all are working perfectly. location yenagoa Bayelsa state.

Hello am interested am in Portharcourt can you inbox me your number.

Finally got my solar panels. 130w poly (x2). Anybody here staying in port Harcourt that need solar/inverter stuff should go to mile 1 or ogunabali. I bought the panels from sunny best at ogunabali.

The only issue I have is, the frames (edges) doesn't look really neat like the panel face. Does this mean the panel have been used before or its normal. Please my ogas in the house, I need your replies.

If u bought ur battery here in lagos , u can as well buy the smart charger urself, all u need is just phone contact, address and directions of the seller, my advice is to buy 30amp and above smart charger for ur 200ah , the kind of 30mins electricity light we get these days , 20amp won't charge it fast
