SOLD
I'm selling a CTEK D250S Dual Battery Charger that was installed in my Four Wheel Camper for about a year.

This charger can be hooked up to both the vehicle alternator circuit as well as a solar panel, and acts like a battery isolator also.

Marketing Spiel:
D250S DUAL​
The D250S Dual has 2 inputs. The Service battery will be charged from the alternator, solar panel, or both in combination.​
The solar panel adjusts itself to the Starter battery voltage.​
The Starter battery will be charged and maintained directly by the solar panel if the Service battery is fully charged.​
D250S Dual features :​
• Multi-step 20 A temperature compensated battery charging and battery maintenance.​
• Battery separation of Starter and Service batteries.​
• Maximum power point tracking for solar panels charging the Service battery.​
• Two power source inputs (alternator, solar, wind, Supply battery and other).​
• Coordination of the two inputs, allowing parallel operation.​
• The solar input will also maintain the Alternator battery.​
• Built in battery guard for the Alternator battery.​

They don't seem to make this exact one anymore but here is a link to the manual:

SOLD
Asking $150 $100 shipped in the US.
