Product Information
10,000W 48V Hybrid Inverter for Whole-Home Backup and Large Off-Grid Systems
The NOVA 12K does three jobs in one box: it inverts 48V battery power to AC, runs an MPPT solar charge controller taking up to 12,000W 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 10,000W inverter can draw well over 208A 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 10,000W continuous. 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, and this unit charges at up to 200A. 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 at up to 200A, as well as charging from solar.
