Please help on this situation.

I have two 200AH battery, and I observed that when it shows low battery, one battery will be reading 10.5V and another 12.2V.

My concern is why is the inverter not drawing consumption evenly from both batteries. Thank you.

First you didn't state how the two batteries are connected - In series or in Parallel.

Abdomox:


Thanks for this. Please I don't know the difference between Series and Parallel connection. Hiw does this affect the battery reading please?

I feel you should get acquainted with more of the common things you'll come across as a DIY solar enthusiast so as to make the experience easier and sweeter. Battery connection methods is one of those.

You batteries reading different voltages apart is what can be called "batteries imbalance" and it can present in both parallel or series connections. It has disadvantage which is that the battery with the lower voltage is likely bad, hopefully salvageable, and ultimately the bad battery will bring down the good one with it so that the two batteries eventually get bad.

Refer to the attached picture for a diagrammatic representation of battery connections.

Don't forget to visit that link posted earlier on. It will also be good for you go to thru the pages, at least skimming thru 'em if you don't have the luxury of time. It will help you to get grasp of the subject matter especially questions about the battery connection methods and problems that may arise therefrom.

Someone help my inveter shows E8 and blinks red light when I plug it to light, what do I do

Inveter brand is soelix

bomb1:


Step1: Place your change-over to "neutral" to prevent PHCN or Gen supply.
Step2: Press the "DG Mode" button on the Inverter for about 10 secs till you get a beeping sound
Step3: Return your power source as appropriate to PHCN or Gen

You should be fine now.

I connected my 1000w suoer inverter/charger to a stabilizer inorder to charge my 100ah battery and it gave a spark and wouldn't charge my battery again what do i do?
Note: Inverter is still functioning, the charger is no longer working

dragnet:

what is the stabilizer's capacity/rating?

aorseer:

Stabilizer's capacity is 2kva

dragnet:

You can give a technician to check the components but I am wondering why that should happen.
Is the stabilizer still working?

Please I have two questions for the expert in the forum
1) at what voltage is a 220ah tubular battery considered DEAD: From 10v downwards, although can be revived if you are lucky

2) at what voltage is it expected for an inverter to beep "battery low" for the safety of the battery
