I have a problem. When the batteries reach 100% the Smartsolar's stop working and the batteries start draining. This happens everyday.
We have 4 x BYD LVL modules, 3 x 250/70 and 3 x 15kva inverters setup as a 3 phase off grid system.
DVCC is forced on and cannot be changed. The MPPTS are ex control.
When the smartsolars stop working, the parameters on the batteries still show a charge limit of 900A so I feel it's not an issue with the BMU for the LVL's.
We are abit stumpted, any idea welcome
