Hi guys

I’ve got 2 new narada 48nfpc100 batteries connected in parallel, but it seems that they are not draining equally. Specifically, it seems pack 2 is typically the one that drains faster. The wiring from the inverter goes to pack 1, with pack 2 parallel connected to 1, so it is weird that pack 2 is the one more drained (e.g pack 1 will have 2 lights in soc, whilst pack 2 will have 3)

Another thing i’ve noticed is that sometimes during low load, pack 1 will go into standby, while pack 2 will service the load.

Most of this occurs during night time with no solar activity, and both will charge up properly during the day.

the only thing i can think of doing at the moment is to put one of the cables from the inverter to the same port on the other battery to see if that helps, but not confident.

Any advice?

Parallel connect the 2 batteries and take the positive from the Inverter to battery one and the Negative wire from the Inverter to battery 2. That is the correct way to do it, although i am not sure how big a difference it will make. 

Thanks, i’ll try that. It is just weird that pack 2 (basically the furtherest one from the load) is the one that drains faster.
