The Victron Multiplus II has all the functionality of the MultiPlus with an optional external current transformer to implement PowerControl and PowerAssist and to optimise self-consumption of solar power with external current sensing. It has built in anti-islanding functionality with an increasing list of country approvals.
PowerAssist and PowerControl
A Maximum Grid or Generator current can be set. The Multiplus-II will then control the energy balance by managing the energy flow to the battery to maintain the maximum load on the energy source.
PowerAssist will augment the load power from the battery if required, while maintaining the maximum configured load on the source.
Solar Energy: AC Power available even during a grid failure
The Multiplus-II can be used in off-grid as well as grid connected PV and other alternative energy systems. It is compatible with both solar charge controllers and string inverters.
Parallel and three-phase operation
Up to 6 Multiplus-II inverters can operate in parallel to increase the power output. In addition to parallel connection, three inverters of the same model can be configured to deliver three-phase power. Furthermore, 6 if these sets can be connected in parallel to increase the three-phase output power.
