Product Information
3,000W 24V Hybrid Inverter for Sheds, Cabins and Small Off-Grid Systems
The NOVA MAX 3K does three jobs in one box: it inverts 24V battery power to AC, runs an MPPT solar charge controller taking up to 3000W 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 3,000W inverter can draw well over 125A from a 24V 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 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 24V 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.
