With award winning Swedish technology, the dual input CTEK-20A charger can draw its power from smart alternators and other 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 photovoltaic panels (via MPPT charger) in parallel to the alternator.
Features:
- 5 step charging algorithm from smart and conventional alternators and solar panels
- Automatic battery separator works without the need for diodes or relays
- Selectable higher output (14.7) or standard one - 14.4V
- Parallel input from both alternator and solar panel
- MPP-tracker with max Voc = 23V !
- Starter battery maintenance charging when your service battery is fully charged
Benefits:
- Continuous, fully automatic charging while you’re on the move for maximum performance, battery life and convenience
- Fixed output charging current - 20A , which prevents high charging currents
- Compatible with smart alternators (ECU - engine control unit alternators). The device will still operate even if the smart alternator is shut off and maintain a stable output of up to 20A to fully charge your battery in the shortest time
