We see this as providing backup power for small devices in the event of a power outage. Medical devices, security systems, and computer equipment would be ideal uses. The output is a pure sine wave with 500 VA at 25 deg C, the built in transfer switch can act so fast it makes the device act as an uninterruptible power supply. The built in charger can charge the batteries at up to 20 amps when external power is available. This MultiPlus shares the same connectivity as the larger units, it can be programmed with a computer using a Mk3 USB interface and Victron Connect. It can be connected to a Cerbo GX for remote monitoring using the Victron VRM.
