Product Information
6,500W 48V Hybrid Inverter for Cabins and Off-Grid Homes
The NOVA 6548 does three jobs in one box: it inverts 48V battery power to AC, runs an MPPT solar charge controller taking up to 8000W of panels, and charges the batteries from the grid or a generator when the sun falls short.
Pure sine wave output matters for anything with a motor, a compressor or a circuit board — laptops, microwaves, fridges, CPAP machines and power tools all run cooler and quieter on it than on modified sine.
Size the battery bank to the load, not just the inverter: a 6,500W inverter can draw well over 135A from a 48V bank at full output, so cable gauge and battery discharge rating matter as much as the inverter itself. Call us on 1-332-291-6885 if you want the sizing checked.

Frequently Asked Questions
What can this inverter run?
Anything up to 6,500W continuous, with 13,000W (5 Seconds) available briefly for start-up surges. That covers lights, a fridge, laptops and power tools, and larger loads like a microwave or small air conditioner. The daily total depends on your battery bank, not the inverter.
What size battery do I need?
Work from your daily watt-hours, not the inverter rating. As a rule, a 48V bank should be able to deliver the inverter's full output without exceeding its discharge rating. We can size it with you on 1-332-291-6885.
Can it charge from the grid or a generator?
Yes. It accepts AC input from the grid or a generator and charges the batteries, as well as charging from solar.
