Hi everyone, we have a very strange situation and would really appreciate any advise. Existing installation, 16 x 605w Canadian panels, 12kw 3 phase Sunsync inverter, 10kw Sunsync battery. We recently purchased a 10kw Eenovance battery (slave) and connected it to the system in parallel. In theory this should have been as easy as plug and play if you follow all the instructions like we did. What we have noticed is that on the Eenovance battery (slave) there is a slider switch, that when it is in the ON position (battery lights are on), it stops the power from the panels and the batteries don't charge. When that slider switch is in the OFF position, everything works as normal.
