Description
The Victron BlueSolar PWM DUO LCD and USB charge controller 12/24V-20A is a PWM solar controller with two separate battery outputs, making it ideal for charging both a starter battery and a service battery on a boat or motorhome from a single solar array. System voltage is detected automatically, a backlit LCD shows status and settings, and two 5V USB ports (2A combined) are built in for charging phones and small devices.
A programmable three-stage charge algorithm supports AGM, GEL, flooded lead-acid and LiFePO4 batteries (with internal BMS), and a remote temperature sensor is included for accurate temperature-compensated charging. The controller is protected against reverse polarity and over-temperature, and the load path includes an automatic low-voltage disconnect.
