Victron Sun Inverter 12/250-15 IEC – sine wave inverter with PWM solar charger

Victron Energy Sun Inverter 12/250-15 IEC combines a pure sine wave inverter and a PWM solar charge controller in one compact enclosure. It converts energy from a 12 V battery system into 230 V AC for suitable domestic and electronic equipment, while also charging the battery from solar panels.

The integrated design reduces the number of components and wiring required, making installation easier in campervans, caravans, boats, professional vehicles and small off-grid systems. Inverter and solar charger parameters can be configured and monitored via Bluetooth and the VictronConnect app, while the VE.Direct port enables integration with GX devices and GlobalLink 520.
