The Quattro-II 12V 3kVA 2x120V is a transformer-based inverter-charger for 12V systems that also passes 120/240V split-phase power through when it is present at the input. It suits boats, RVs, and cabins that want 240V loads such as water pumps to run only on shore or generator power.

For systems that need more headroom than a 3kVA unit, the MultiPlus-II 48V 5kVA pairs an iron-core transformer with a 70A battery charger. It gives 4,000W continuous at 120V with 9,000W of surge, enough to start welders, compressors, and well pumps smoothly. It is aimed at off-grid homes, subpanels, and battery backup systems that may grow over time.
