INV Off-Grid Hybrid Inverter
The battery-based workhorse of the range: six power classes, three battery voltages, and a solar charger already inside the box.
The off-grid hybrid inverter is the least glamorous product in a solar catalogue and the one that decides whether an installation works. It has to start a pump, ride through a grid dip, charge from whatever source is available and keep doing it for a decade in a shed.
The INV series covers 1.2 kW to 10.5 kW on 12, 24 and 48 V batteries, with a 100 A MPPT charger built in. The topology is shared across the range, so an installer who has commissioned one model has commissioned them all — the difference is battery voltage and current rating.
Where the series earns its place is surge. A 200 % peak for ten seconds is not a marketing figure; it is the difference between starting a 1 hp well pump and watching the inverter trip to fault.
