Charging with two independent multiplus

So my client wants to power two cabins with 2 independent multiplus inverters and a shared pylontech lithium bank and single panel array. Each multiplus will have a backup generator. Not sure if charging from genset simultanously is a problem or even if can be set up in Venus. Any sugestions welcome.

it’s not a problem unless the combined combined charge current is higher then the house battery bank can handle. If the battery bank is large it will be fine.

If you want to share a Venus for monitoring the two inverters need to be programmed as a parallel system. And you will need an MK3 to usb for set up and programming.

If you choose to have two separate systems, then DVCC wont work to control the second systems charge, so some care will be needed there (possible warranty void concerns).

And the bank needs to be able to support the full loads of both inverters/be the correct minimum size for two systems.
