BMV at 95%, whilst low voltage alarm comes on, and I’ve only got 43v
I have a 48v system.
12 batteries in strings of 3.
Going in to an easy solar 3kva. 48v.
Reset BMV to 5% charge. After putting in 10kwh off a generator yesterday, the volts went up to 57.5 and absorption. And 30% charge.
Turned off generator, volts dropped to 50v, then over night dropped down to 45.29 and 25.5% charge.
Any suggestions most appreciated
Cheers
Ian
See the DIY FAQ sticky post, items 2 and 3 are often the cause of your symptoms.
Welcome.
It sounds like the BMV has not been configured correctly.
Have a read of this post and adjust your settings accordingly.
