Where to use it
The MultiPlus-II 48/4k5/55-32 is a 48V inverter/charger for off-grid homes, sheds and cabins, grid-connected battery (ESS) systems, and large boats and vehicles. It runs 230V appliances from the battery bank, charges the batteries from the grid or a generator at up to 55A, and takes over the main output in under 20 milliseconds if the grid fails, so computers and other electronics keep running.
With PowerControl and PowerAssist it can make a small generator or limited supply go further: you set a maximum input current and the MultiPlus-II tops up peaks from the battery. It works with MPPT solar charge controllers and grid-tie inverters, and several units can run in parallel or three-phase for larger systems. Add a Cerbo GX for remote monitoring on VRM, or a VE.Bus Smart Dongle to check it from your phone over Bluetooth.
