Victron Sun Inverter 12/250-15 IEC 12V 250VA Inverter with PWM Solar Charge Controller

The Victron Energy Sun Inverter 12/250-15 IEC (MPN: SIN121251100) combines a 12-V sine-wave inverter with an integrated 15-A PWM solar charge controller. The unit provides 250 VA of rated power, or 200 W of continuous power at 25 °C, and can simultaneously use connected solar panels to charge the battery. Built-in Bluetooth, the VictronConnect app, and VE.Direct enable system configuration and monitoring. An ECO mode further reduces self-consumption during low-load conditions.

230 V power supply from a 12 V battery system

The Sun Inverter converts the DC voltage of a 12-V battery system into 230 V AC voltage. At 25 °C, the unit provides 250 VA rated power or 200 W continuous power. At 40 °C, the specified continuous power is 175 W. Up to 400 W can be provided for short periods.

The increased peak power is particularly relevant for loads with high inrush current requirements. This makes the inverter suitable for compact mobile and stationary applications in which smaller 230-V loads are to be operated independently of the public power grid.

Integrated PWM Solar Charge Controller

In addition to the inverter, the Sun Inverter features an integrated PWM solar charge controller. This supports a maximum PV current of 15 A, a maximum PV voltage of 25 V, and a PV power of up to 375 W. This allows the connected 12-V battery to be charged directly via suitable solar modules.

The charging algorithm is configurable. Using the ON/OFF/CHARGER-ONLY switch, you can choose to operate the entire unit, shut it down completely, or activate only the solar charging function.

ECO Mode for Lower Self-Consumption

In ECO mode, the inverter switches to energy-saving standby mode when the load is low or absent. At regular intervals, the device checks whether a sufficiently high load is present again and then automatically resumes normal inverter operation.

Power consumption without a load is 4.2 W. In ECO mode, this value is reduced to 0.8 W. This makes the feature particularly suitable for battery-based systems where a 230-V load is not continuously active.

Bluetooth, VictronConnect, and VE.Direct

The Sun Inverter can be connected directly to the VictronConnect app via its built-in Bluetooth. There, operating parameters such as battery voltage, AC output, load, as well as solar voltage and solar current can be monitored. Additionally, various operating and charging parameters can be configured.

Via VE.Direct, the device can also be integrated into other Victron system components and monitoring solutions.

Remote Control and BMS Integration

The Sun Inverter can be turned on and off externally via the remote connection. Additionally, a compatible battery management system can control the device and, under certain battery conditions, shut down the inverter or the solar charge controller.

Compact Design and Integrated Protection Functions

The Sun Inverter features a steel housing with a plastic cover and measures 86 × 165 × 260 mm, weighing 2.4 kg. The permissible operating temperature range is from -40 to +60 °C, although power output is reduced above 40 °C.

The integrated protection functions include protection against output short circuits and overloads, as well as protection against excessively high or low battery voltage, overtemperature, and excessive DC ripple voltage.
