Victron Energy - 12V - 250VA - Sun Inverter 12/250-15 IEC Plug + 15A PWM Solar Charge Controller

Victron Sun Inverter 12/250-15: Integrated 12V Inverter and Solar Charge Controller for Off-Grid Power

Compact 250VA Pure Sine Wave Inverter with Built-In 15A PWM Solar Charger

The Victron Sun Inverter 12/250-15 combines a 250VA pure sine wave inverter and a 15A PWM solar charge controller in a single, space-saving unit. Designed for 12V off-grid systems, it delivers reliable 230V AC power from your battery bank while simultaneously managing solar charging. This integrated approach simplifies installation and reduces wiring complexity, making it an excellent choice for caravans, motorhomes, boats, and remote cabins where space and efficiency are critical.

Unlike separate inverter and charger setups, the Sun Inverter streamlines your power system. The full bridge toroidal transformer design provides robust, clean power suitable for sensitive electronics, while the integrated PWM controller efficiently harvests solar energy to keep your batteries topped up. With Bluetooth monitoring via the VictronConnect app and a VE.Direct communication port, you have full control and visibility over your energy system, whether you're on the road or at a remote site.

Reliable Power Conversion with High Surge Capability

The inverter section delivers 250VA continuous output (200W at 25°C) with a 400W peak power rating, enabling it to start demanding loads such as LED lighting power converters, small power tools, and halogen lamps. Its toroidal transformer topology has been proven over decades of field use, offering inherent short-circuit protection and thermal resilience. The unit automatically derates output at elevated temperatures, ensuring safe operation even in challenging environments.

For energy-conscious users, the ECO mode reduces idle consumption to just 0.8W by cycling the inverter on and off to detect loads above a preset threshold (default 15W). This feature is particularly valuable in solar-powered installations where every watt-hour counts, extending battery runtime during periods of low solar input.

Integrated 15A PWM Solar Charger for Efficient Battery Management

The built-in 15A PWM charge controller supports up to 375W of solar input (36-cell panels) and is fully programmable via the VictronConnect app. You can adjust charge voltages, battery algorithms, and temperature compensation (with optional sensor) to suit lead-acid, AGM, or lithium batteries. The controller initiates charging as soon as PV voltage exceeds battery voltage, maximising energy harvest throughout the day.

This integration eliminates the need for a separate solar regulator, reducing component count and potential points of failure. The screw terminals for both battery and PV connections accept up to 10mm² (approx. 8 AWG) and 4mm² (approx. 12 AWG) cable respectively, simplifying installation without specialised tools.

Advanced Monitoring and Control

Stay informed with Bluetooth connectivity built into the unit. Using the free VictronConnect app on your smartphone or tablet, you can monitor real-time data including inverter input/output voltage, load percentage, solar power, and battery status. Configure settings such as low battery cut-off levels, output voltage (210-245V), frequency (50/60Hz), and ECO mode sensitivity to match your specific requirements.

The VE.Direct port enables integration with Victron's GX monitoring devices (e.g., Cerbo GX) or the GlobalLink 520 for remote monitoring via the VRM portal. A remote on/off terminal allows connection of an external switch or the optional Phoenix Inverter Control panel for convenient operation.
