Micro-invertes and multiplus

I am in the very early stages or designing an off grid Solar power for a Bush Block. I am looking to go with the Multipass 48/3000.

I will have a generator to charge the batteries and as a back up.

I am looking at the advantages and disadvantages of micro-inverters connecting the panels straight into the Multipass (looks like you do this on the outbound side) or using the more traditional MTTP (which I understand from some great videos).

Is it as simple as plugging the panel AC output into the outbound multipass?


Any thoughts or guides would be much appreciated.

Yes, you can do this. Batteries will charge from the PV Inverters.
You'll need to observe the 1:1 rule, do not install more PV inverter / PV power than the power of the MultiPlus.
The MultiPlus will frequency shift to reduce or to stop the PV inverters if the batteries get full.

There is some documentation here:
