Why won’t my CTEK D250S Dual Charge from Solar Panels?

The CTEK D250S Dual DC-DC Charger won't charge from solar panels while it is getting input from another power source.

What this means is, if you have a CTEK D250S Dual installed in your 4WD, it will only charge from solar when you’re vehicle is turned off and it is no longer receiving power from the alternator. This allows you to charge from your alternator while you’re on the move, then charge from your solar panels when you’re taking a break, ensuring your batteries are maintained and ready to power your gear.

It’s also important to take into consideration the type of solar panels you use. The CTEK D250S Dual has a built in solar regulator, so the panels you use must NOT have regulators built into them. If you use the CTEK D250S Dual with panels which have solar regulators, it will be unable to charge your batteries from them.

You can also boost the power you get from your CTEK D250S Dual, by adding a CTEK Smartpass to your system. The CTEK Smartpass is an energy management unit which optimises the power of the CTEK D250S Dual. The CTEK Smartpass is not a standalone battery charger, and is solely designed to work with the CTEK D250S Dual.
