The MultiPlus-II prevents a limited AC power source such as a B. a generator or a shore power connection is overloaded. First the battery charging process is automatically reduced to protect against overloading. Next the output of a generator or shore power supply is boosted with energy from the battery. In the event of a grid failure or if shore power or If the on-board generator is interrupted the inverter of the Multi is automatically switched on and takes over the supply of the connected loads. The switchover happens so quickly (less than 20 milliseconds) that computers and other electronic devices can continue to operate without interruption. In connection with a GX device (e.g. Cerbo GX) you can use the free VRM App and Free VRM Portal website to control your Multi and the system.
