Additional Solar Panel MPPT Information for Ctek D250SE
Max open circuit voltage from panel is only 23v.
Always check specification from supplier as a higher voltage
will damge the charger and will invalidate warranty.
With award winning Swedish technology, the dual input D250SE which has now replaced the D250SA with added
connection to lithium batteries can draw its power from smart alternators andother DC sources, making it the ideal
charger for vehicles that don’t have access to a mains power supply. Its dual input capability means it can draw
power from solar and wind sources, in parallel to the alternator.
The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to charge, condition and
maintain any 12V lead acid service battery from 40-300Ah, including Wet, MF, Gel, AGM. EFB and Ca/Ca & lifepo4 Lithium.
The D250SE uses patented technology so it’s safe for you and your vehicle’s electronics. It’s also IP65 classified
(splash and dust proof, and suitable for outdoor use) and comes with a 2-year warranty.

Linked with the smartpass120 giving you up to 140amps output
120A DC/DC Power Management Solution
Separate, prioritize and boost batteries and equipment
Smartpass 120 charges and supplies the service battery and equipment with 120A, separates critical equipment from non-critical equipment ensuring that radio, emergency lights and navigation systems always have power.
Smartpass 120 is a 120A Power Management Solution which distributes, controls and maximises the available energy from your alternator to power service batteries and consumers. SMARTPASS 120 handles all 12V batteries between 28-800Ah. The Smartpass 120’s Battery Guard function ensures that critical equipment such as radio, emergency lights and navigation systems always have power and take priority when the voltage on the service battery is low disconnecting non-critical consumers. The unit’s Battery Guard will protect your service battery from total discharge and built in over temperature protection reduces charge current before the battery temperature gets too high. SMARTPASS 120 is compatible with the D250SE or D250SA 20A on board charger.
