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 800 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 35 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.
