Dual input 20A charger with selectable charge voltages. No need for a VSR this will charge both your house and start batteries and is IP65 rated.

Choose a solar panel with an open circuit voltage of less than 23 volts and less than 300 watts. Our 150 watt panels are the ideal panel for this charger. Two can be wired in parallel to get the 300 watts.

Connect your house battery as the main battery for the solar to charge and your start battery as the battery to trickle charge.

The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead-acid or ­lithium* service battery from 40–300Ah. It has ­selectable charge algorithms for AGM and lithium* batteries and can use power through its dual input from alternator and solar panel. When the service battery is fully charged, the D250SE will ­automatically redirect maintenance charge ­power to the starter battery. The D250SE can maintain a stable output up to 20A to vehicles fitted with smart ECU controlled ­alternators and also has a temperature sensor for ­optimised charging, regardless of weather conditions. *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
