SRNE RIC12-3kW Pure Sine Wave Inverter / Charger – Smart AC Power for Campervans & Off-Grid Systems

When you’re building a serious power system for a campervan, motorhome, boat or off-grid cabin, you need more than just batteries. You need a reliable way to turn 12V DC into clean 230 V AC – safely, efficiently, and with enough power to run real-world appliances.

The SRNE RIC12-3kW Pure Sine Wave Inverter / Charger is designed exactly for that job. Compact yet powerful, it delivers up to 3 kW of continuous AC output from a 12 V battery bank, with a pure sine wave that’s safe for sensitive electronics and high-demand loads.

What Is the SRNE RIC12-3kW Inverter / Charger?

The SRNE RIC12-3kW is a combined pure sine wave inverter and battery charger. It takes power from your 12V battery bank and converts it into 230V AC, while also offering integrated battery charging when connected to mains (shore power or generator).

Key headline specs include:

  • 12V DC input / 230 V AC output – perfect for 12 V leisure systems.
  • 3,000 W continuous output with up to 6,000 W surge for start-up loads.
  • Pure sine wave output – safe for laptops, TVs, chargers, fridges, pumps and other sensitive devices.
  • High efficiency with low no-load consumption and ECO mode.
  • Integrated charger for topping up your batteries from 230 V mains.
  • Comprehensive protection – under/over-voltage, overload, short-circuit and over-temperature.

Pure Sine Wave – Why It Matters

Not all inverters are equal. Modified or “quasi” sine wave inverters can cause:

  • Extra heat and noise in motors and compressors.
  • Glitches in chargers, TVs and laptops.
  • Reduced efficiency and shortened appliance life.

The RIC12-3kW outputs a clean pure sine wave, closely matching grid power. That means:

  • Fridges, pumps and fans run smoother and quieter.
  • Laptops, TVs and electronics work as intended.
  • Less stress on appliances during long-term off-grid use.

Perfect for Campervans, Motorhomes & Off-Grid Builds

The SRNE RIC12-3kW is particularly well-suited to:

  • Campervans and van conversions running fridges, induction hobs, kettles, laptops and chargers.
  • Motorhomes with mixed 12 V and 230 V onboard systems.
  • Off-grid cabins or garden offices powered by battery and solar.
  • Marine use where quiet, reliable AC is essential.

Thanks to its 3 kW continuous output and 6 kW surge, the inverter can comfortably handle start-up loads from compressor fridges, pumps, some power tools and other inductive loads commonly found in leisure vehicles.


Integrated Battery Charging from Shore Power

The “charger” part of the RIC12-3kW comes into play when you plug into 230 V hook-up or a generator. Instead of using a separate mains charger, the inverter can:

  • Charge your 12 V leisure battery bank from AC power.
  • Manage charging profiles for different battery types (including lithium and AGM).
  • Provide seamless switchover between battery and mains where appropriate.

This simplifies the system design: fewer separate boxes, fewer cables, and a more integrated, professional setup.

Smart Protection & Communication

The RIC12-3kW includes multiple layers of protection to keep both the inverter and your batteries safe:

  • Over-voltage and under-voltage protection on the DC side.
  • Overload and short-circuit protection on the AC output.
  • Over-temperature protection with intelligent fan cooling.

Selected models also offer communication options (such as RS485/Bluetooth via compatible modules) for monitoring system performance, depending on your larger SRNE setup.


Typical System Layout

In a typical campervan or off-grid install, the RIC12-3kW would sit alongside:

  • A 12 V lithium leisure battery bank (for example, SkyEnergi LiFePO₄ batteries).
  • A solar system with an MPPT controller (e.g. SRNE SAA or dedicated MPPT).
  • A DC distribution system for lights, pumps and 12 V loads.
  • Hook-up inlet for mains charging when at a campsite or driveway.

The inverter takes DC power from the battery, provides 230 V AC for sockets and appliances, and charges the battery when mains power is available.


Pros & Considerations

Pros Considerations
3 kW continuous / 6 kW surge – plenty for most van and off-grid setups. Needs a well-sized battery bank and thick DC cabling.
Pure sine wave – safe for all sensitive electronics. Poor installs (ventilation, fusing, cable size) can limit performance.
Integrated charger simplifies system design. Higher-end unit compared to simple plug-in inverters.
Compact and designed with mobile/off-grid use in mind. Plan your loads carefully so you don’t exceed 3 kW continuous.

Is the SRNE RIC12-3kW Right for Your Build?

The RIC12-3kW is a great fit if you:

  • Want to run “home-style” 230 V appliances from a 12 V battery bank.
  • Are building a high-spec campervan, motorhome or off-grid system.
  • Plan to combine solar, battery and shore power into one integrated setup.
  • Value clean, reliable AC power and long-term durability.

If your needs are lighter (phone charging, lights, a small laptop), a smaller inverter might be enough. But if you’re serious about off-grid comfort, 3 kW gives you the headroom to live much more like you do at home.
