Victron MultiPlus II 48V hybrid inverter-charger with 4,5 kVA AC output, 2 MPPT trackers, and 24-month warranty for off-grid and grid-tied solar systems.
Victron Energy MultiPlus II 48/4k5/55-32 – High-Performance 48V Hybrid Inverter-Charger
The Victron Energy MultiPlus II 48/4k5/55-32 is a grid-connected or off-grid inverter-charger designed for 48V battery systems. It combines a pure sine wave inverter with a built-in battery charger, delivering 4.5 kVA of AC output power for reliable energy conversion.
4.5 kVA AC output provides sufficient capacity for medium-sized household loads and small commercial applications
2 MPPT trackers maximise solar harvest from two independent PV strings, optimising energy yield throughout the day
Hybrid inverter-charger architecture enables simultaneous grid feeding and battery charging without additional components
24-month manufacturer warranty provides long-term investment protection and service confidence
What sets the MultiPlus II apart
The MultiPlus II integrates inverter, charger, and MPPT solar controller in a single unit, reducing system complexity and installation effort. Its 48V operating voltage is well-suited for modern battery storage setups, and the 4.5 kVA output handles typical residential and light-commercial loads efficiently.
Ideal for...
Off-grid and hybrid solar installations with 48V battery banks, small to medium households, and light-commercial setups where a combined inverter-charger with MPPT solar input is required. Suitable for installers and system integrators building reliable, scalable energy systems.
