The Victron Sun Inverter 12/250-15 IEC combines a pure sine wave inverter and a PWM solar charge controller in one compact unit. It converts 12V DC battery power to 230V AC while managing solar panel input to keep the battery topped up, making it a practical choice for small off-grid and standalone power systems.

Key features

• Combined function, inverter and 15A solar charge controller in a single unit, reducing wiring and component count.
• DC input, 12V.
• AC output, 250VA, suitable for lighting, communications equipment and low-power appliances.
• Connector standard, IEC, compatible with UK and European installations.
• Weight, 2.8 kg.
• Protection, overload, over-temperature and deep discharge protection built in.

Product overview

This unit replaces two separate devices with one: a sine wave inverter and a PWM charge controller. The 250VA output suits low-power AC loads, and the 15A controller input allows a small solar array to maintain a 12V battery bank without extra equipment. The IEC variant is wired to UK and European standards, so it fits directly into compliant off-grid setups. As a Victron product it works within the wider Victron ecosystem but does not require any additional Victron components to operate.

Applications

• Small off-grid cabins, shelters or remote monitoring stations.
• Marine and narrowboat installations where a combined unit saves space.
• Caravan and motorhome auxiliary power with low AC load requirements.
• Telecoms and security enclosures powered by a small solar and battery setup.
• Rural outbuildings without a grid connection needing basic AC supply.

Installation notes

Fit by a qualified electrician or experienced solar installer. Battery bank, cabling and fusing must be rated correctly for 12V DC at the required current, and the solar input must not exceed the 15A charge controller rating. For UK installations, check current wiring regulations (BS 7671) and confirm requirements with your local DNO before proceeding.
