Victron Multiplus 5kVA 4kW 24V/48V Inverter/Charger

The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid Power Assist technology, plus multiple system integration features. The MultiPlus will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.


  • Two AC Outputs.
  • Virtually unlimited power thanks to parallel operation.
  • Three phase capabilities.
  • Power Control - Dealing with limited generator, shore side or grid power.
  • Power Assist - Boosting the capacity of shore or generator power.
  • Solar energy: AC power available even during a grid failure.
  • System configuring.
  • On-site Monitoring and control.
  • Remote Monitoring and control.
  • Remote configuring.

Victron Multiplus 5000W does what it says on the boxReview by Graham Peck
We purchased a Victron Multiplus 5000W unit and two deep 120Ah batteries through and it has been the best buy. Other companies we know have gone the generator route and other models of inverters and of those over 60% are having issues due to charging times etc. We have not had any issues and the switch over from mains to batteries is seamless with no disruption. I have 10 pc's and monitors and some test equipment running and have not had any issues with the 2:30 hr load shedding windows. The unit is rock solid and the support from is fantastic.
