As per the title, is it possible to run a 12/2000 Multi and a 48/5000 Multi ii in parallel for an ESS?
Back story, I am based in Australia and have a caravan with 7.2kWh of 12v battery, a Cerbo GX, MPPT, 760w of solar and a Multi 12/2000. It is sitting dormant 90% of the time in my driveway, and shortly we will be setting up a 48v 5000 Multi ii, Cerbo GX and 16kWh of battery on our house (single phase).
Neither of these batteries are managed via GX, and use a smartshunt in both applications
Wondering if it is possible to tie the two together, and utilise the power in the caravan as part of our ESS when it is parked up at home (We have AC PV on the house, which will be utilised to charge the 16kWh of house batteries before the excess is exported, and then utilise battery at night until they are drained).
