Victron - Sun Inverter 12/250-15 IEC [SIN121251100] MultiPlus 12V 230V and efficient monitoring for LithiumThe Sun Inverter combines a sinewave inverter and a PWM solar charger in one enclosure and is easy to install, with a minimum of wiring. The inverter allows you to power domestic equipment requiring 230V AC using 'leisure' or 'automotive' batteries rated at 12V or 24V. The solar charger ensures that the batteries are being charged by energy harvested from your solar panels. The charge algorithm is programmable. The inverter and solar charger
