Overview
Charge your house battery from an AC200L
The D40 is a 400W DC-DC battery charger built to work with the BLUETTI AC200L. It takes 48V DC from the AC200L and charges a 12V house battery in your caravan, RV or boat, or runs 12V appliances directly.
It also works from solar panels or a starter battery, and has charge profiles for LiFePO₄, AGM/gel, lead-acid and calcium batteries.
BLUETTI lists the BLUETTI AC200L as the compatible power station. The D40 plugs into the AC200L’s 48V DC output. It can also charge from solar panels or a starter battery (12–36V).
