MAGNUM MS4048 4000 W, 48 VDC 120 VAC 60 HZ OFF-GRID SINEWAVE BATTERY INVERTER

We have had the Inverter for a year. In a traveling school bus conversion. We bounced around for 8,000 miles. We have 3kw solar set up. The inverter is extremely quiet and efficient. It performs exactly like it should. It is expensive, and for good reason.
