NOVA 3K12 Pure Sine Wave Inverter — 3000W Reliable Power
Overview
The NOVA 3K12 delivers clean, efficient AC power from a 12V battery source. It produces a pure sine wave with low distortion, switches automatically during outages, and includes protections and monitoring for safe, dependable use in homes, RVs, boats, or backup setups.
Benefits
- Protect sensitive equipment — clean (<5% THD) pure sine output keeps medical devices, servers and electronics running reliably.
- Extend battery run-time — up to 91% peak efficiency and low standby draw mean longer operation between charges.
- Avoid interruptions — automatic transfer (?20 ms) and selectable Fast/Normal modes keep refrigerators, computers and tools running without user intervention.
- Reduce worry about faults — adjustable low-voltage shutdown and built-in overload/short-circuit/overheat protection minimize risk to batteries and loads.
- Use it outdoors or at sea — optional drip shield and temperature-managed cooling fan increase durability in harsh or marine environments.
- Know what’s happening — the smart LCD and LED indicators show voltage, load and system status so you can act quickly if needed.
- Install with confidence — UL-listed compliance and compatibility with 12V deep?cycle and LiFePO4 (with BMS) batteries simplify integration.
Features
- Pure sine wave AC output with total harmonic distortion <5% for clean power delivery.
