NOVA 3K12 – 3,000W 12V Inverter with Transfer Switch
SKU:RS-V3P12TS
Product Information
3,000W 12V Pure Sine Wave Inverter for RVs, Vans and Mobile Builds
The NOVA 3K12 delivers 3,000W of pure sine wave AC from a 12V battery, and its built-in transfer switch hands over to shore power automatically whenever you plug in — no manual switching, no interruption to what is running.
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. Total harmonic distortion stays <5%.
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.
