The Rich Solar NOVA SWITCH 3K 3000W 12V Pure Sine Wave Inverter With Built-in Transfer Switch (RS-V3P12TS), formerly called the NOVA 3K12, converts 12V battery power into 3,000W of continuous pure sine wave AC power with 6,000W of surge for 5 seconds. When shore power or a generator is connected, its built-in transfer switch passes that power through to your loads, and it switches back to inverter power in under 20 ms when the AC source drops out.
The NOVA SWITCH 3K works with 12V deep-cycle and lithium batteries with a BMS, offers selectable 108V, 110V or 120V output at 50Hz or 60Hz, and can turn on and off with the vehicle's ignition. It is certified to UL 458 and FCC Part 15, and it is built for RVs, campers, trailers, vans and boats.
The inverter delivers 3,000W continuous, or 25A at 120V, with 6,000W of surge for 5 seconds to start compressors, pumps and power tools. Total harmonic distortion under 5% gives clean, stable power for sensitive electronics and household appliances, and peak efficiency is 91%.
A transfer relay rated at 30A switches automatically between shore power and inverter power in under 20 ms. The AC input accepts utility power or a generator at 120V nominal, with full power across an 80V to 140V AC range.
Select 108V, 110V or 120V output and 50Hz or 60Hz frequency to match your equipment. Input frequency is selectable between 50Hz and 60Hz, with a 45Hz to 70Hz input frequency range.
Wire the inverter to the vehicle's ignition circuit so it turns on and off automatically with the engine, or use a manual remote switch.
Set the low-voltage shutdown anywhere from 10.5V to 12.8V to suit lead-acid or lithium batteries. Overload, short-circuit and over-temperature protection are built in.
The NOVA SWITCH 3K is rated to operate from -40°F to 160°F at 5% to 95% non-condensing humidity, and it offers RS232 and RS485 communication ports.
RVs and fifth wheels. Run a microwave, induction cooktop and other large loads from a lithium bank while boondocking, and switch to shore power automatically at the campground.
Camper vans. Let the inverter start with the ignition and power AC loads on the road.
Generator backup. Pass generator power to your loads when it runs and fall back to battery power when it stops.
Boats. Switch between dock power and the house battery without changing plugs.
Work trucks. Power tools and chargers from the battery with automatic ignition control.
Versus the Rich Solar NOVA PURE 3K. The NOVA PURE 3K is a stand-alone inverter with outlets and a remote. The NOVA SWITCH 3K adds a built-in transfer switch, ignition control, selectable output voltage and frequency, and RS232/RS485 ports.
Versus an inverter with a separate transfer switch. A separate transfer switch adds another box and more wiring. The NOVA SWITCH 3K builds it in.
Versus the NOVA SWITCH 2K. The 2K version provides 2,000W continuous and 4,000W surge in a slightly smaller, lighter case, and draws less battery current at full load.
This may be a good fit if
Yes. Rich Solar now sells the RS-V3P12TS under the NOVA SWITCH 3K name.
Under 20 ms, which helps keep connected equipment running when shore power is lost.
Rich Solar does not list a charger for this model. Use a separate converter or battery charger, such as the Rich Solar 100 Amp Power Converter.
Yes. It is compatible with 12V deep-cycle and lithium (BMS) batteries, and the low-voltage shutdown is adjustable from 10.5V to 12.8V.
The Rich Solar NOVA SWITCH 3K 3000W 12V Pure Sine Wave Inverter With Built-in Transfer Switch gives RVs, vans and boats 3,000W of clean power and seamless switching between battery and shore power. At Outbound Power, we help customers plan inverters, chargers and battery banks for mobile systems. If you have questions, our team is happy to help.
