Description
Overview
The Rich Solar NOVA 3K12 converts the energy stored in a 12V battery bank into 3000W of clean, pure sine wave AC power. When incoming AC power drops out, the built-in automatic transfer switch moves your connected loads to battery power in under 20 milliseconds. An LCD shows voltage, load and system status at a glance.
Who it’s for
- Owners of a 12V deep-cycle or lithium (BMS) battery bank who need household-grade AC power.
- Setups that run sensitive electronics, such as computers, servers or medical equipment. Output distortion is under 5%, and a fast transfer mode is built in.
- Damp or harsh locations. Rich Solar describes the build as marine-grade, with an optional drip shield and a temperature-regulated cooling fan.
Key benefits
- Clean power: pure sine wave output with under 5% total harmonic distortion (THD).
- Efficient: rated at 91% efficiency with low standby consumption, so less of your battery is wasted.
- Two transfer modes: Normal for fridges and tools, Fast for computers and servers.
- Protects your battery: adjustable low-voltage shutdown from 10.5V to 12.8V.
- Built-in protection: against overload, short circuit and overheating.
