Hi, I have 2 questions here.

1, I am currently waiting for a 3 phase mains grid system to be quoted and if i go down this route I want to be able to charge my batteries up at night using my Multpluss chargers, set to a time to charge and stop charge, and then during the day i can use my batteries on the multipluss, unless i need extra power then i need the mains to click in, is this possible in assistance?

  1. Even thou i have a 3 phase multiplus system installed at the moment is it possible if i get a single phase grid system, i can charge my batteries using the single phase incomer, but still run a 3 phase system?

How?

When setting up the 3 phase inverter group, you need to deselect the charge as group function, that way you can charge the battery from one inverter, whilst the other 2 remain in invert mode, so continuing to supply the other 2 phases. This is for charging from single phase. Otherwise, the 2 inverters will block the charging, as there is no ac input.

Just remember that disabling switch as a group also prevents ESS being used, in case that was a requirement.
