High-output 12V AC power with automatic source transfer
Convert a properly sized 12V battery bank into 3,000W of clean 120V power.
The RICH SOLAR NOVA 3K12 is a 12V pure sine inverter with an integrated transfer switch for RVs, vans, trailers and off-grid systems. It supplies 3,000W continuous 120V output and can transfer between incoming AC and battery power in 20 milliseconds or less.
At a glance
Start with voltage, continuous output and surge
At 12V, full output requires very high battery current. The battery bank, BMS, busbars, conductors, lugs, disconnect and overcurrent protection must all support the continuous and surge demand with acceptable voltage drop.
System fit
Design the battery and charging side before choosing loads.
Match a 12V battery bank to the inverter’s operating window and current demand, then confirm AC output, grounding, neutral treatment, transfer behavior and branch-circuit protection. This inverter does not include a solar charge controller. Plan charging equipment separately for the battery bank.

Warranty eligibility and remedies depend on the written terms, product registration where required, correct system voltage, approved installation practices and operation within the electrical and environmental limits.
Common questions
NOVA 3K12 system questions
How large should the battery bank be?
Size it from required runtime and current capability. At full 3,000W output, the inverter can draw roughly 250A at nominal voltage before losses, so one battery may not support the required current even when its energy rating looks large enough.
Will it run my air conditioner or well pump?
Only if continuous watts, start-up surge, voltage and frequency all fit—and the battery bank can supply the DC current without excessive sag. Use measured or manufacturer start-up data for the exact load.
Can it power 240V loads?
This model is listed for 120V output. Do not assume native 240V support; choose a compatible split-phase architecture when 240V appliances or service equipment are required.
Does it include the battery and solar panels?
No. This listing covers the inverter. Storage, solar generation, disconnects, protection, distribution and site-specific installation materials are separate.
