Product Information
3,000W 12V Inverter Charger for RVs, Vans and Backup Power
The NOVA SUPERCHARGER 3K is an inverter and a battery charger in one unit. It turns 12V battery power into clean AC, and when shore or generator power is available it reverses and charges the bank instead.
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 3,000W inverter can draw well over 250A from a 12V 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 3,000W continuous, with 6,000W (5 sec) 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 12V 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 — that is the point of this model. Plug into shore or generator power and it charges the bank while passing power through to your loads.
