The MultiPlus-II GX brings the full feature set of the MultiPlus-II together with a built-in Venus GX communications and control centre, so there is no separate GX device to wire in. Advanced features such as uninterrupted power supply, load limit control, and supplementing limited grid power with battery power, can all be controlled straight from a phone or smart device, with remote monitoring built in from the start. G98 approved for UK grid connection.
ESS (Energy Storage Systems): the MultiPlus-II GX is the key component in a Victron ESS, combining flexibly with MPPT solar chargers or grid-tie PV inverters.
Uninterrupted AC power (UPS function): if grid, shore or generator power fails, the inverter takes over the connected loads in under 20 milliseconds, so computers and other electronics keep running without disruption.
