As anyone successfully installed a ESS system with the Multiplus 2 installed with PV on AC-out1 (Grid tied) but also another inverter/charger on AC-out1? The reason for asking is I've been offered a a large quantity of 12v batteries and a 24v inverter/charger of which I was thinking I could use on the AC-out1 to charge and discharge under the demand of the Multiplus (charge when export to grid>3kW or charge on off-peak electric, discharge if demand greater than 4kW) Pro's and con's to this idea? In short, its going to be a test rig for a few ideas bit I dont want to trash my Multiplus, but I think ideally it would need to be under the control of the mUltiplus.
Existing setup - Multiplus II GX 48v 5kVa with 20kWh of batteries
Proposed addition - 24v 3kva inverter charger with 2S2P 12v proving a total of 400ah
