What Is the Victron MultiPlus-II 5kVA?
The Victron Energy MultiPlus-II 48/5000/70-50 is a 5kVA (4,000W) inverter/charger combining a true sine-wave inverter, advanced battery charger, and AC transfer switch in one compact unit.

PowerAssist — Grid Boosting Technology
PowerAssist allows the MultiPlus-II to supplement a limited grid or generator connection. If your grid supply is only 20A but your loads require 40A, PowerAssist draws the difference from your battery bank — preventing tripped breakers while maximising your available power. Critical for homes on weak grid connections or those using a small generator as backup.
ESS Grid Integration
When paired with a Victron Cerbo GX, the MultiPlus-II becomes a full Energy Storage System (ESS) — intelligently trading energy between solar, battery, and grid based on time-of-use tariffs and load-shedding schedules. VRM (Victron Remote Monitoring) provides real-time dashboards accessible from any device worldwide.

Tebogo Mahlangu –
The Victron MultiPlus-II 5kVA Hybrid Inverter/Charger has been running our home without interruption since installation. Load shedding is now completely irrelevant to us. The system handles everything from the fridge to the TV and aircon without any drop in performance. Delivery from PowerVault was quick and the packaging was solid.
Refilwe Lekota –
Installed the Victron MultiPlus-II 5kVA Hybrid Inverter/Charger about three months ago and I cannot believe the difference. Our electricity costs have dropped significantly and we no longer stress about outages. The unit is whisper quiet and the monitoring app works perfectly. Very happy with PowerVault.
