The CTEK D250S is a Premium Battery Isolator, a Smart Power Relay, Solar Panel Voltage Controller with MPPT solar power management functionality and a temperature compensated 20 Ampere smart battery charger all combined into one multi-functional product. The DUAL on-board charger, charges while you drive; it gathers energy from multiple DC power sources (the alternator(s), solar panels and wind power generators) and optimizes power to properly charge your service battery bank with microprocessor controlled smart charging algorithms and provides temperature controlled charging to meet the charge requirements of your service battery bank in any weather. It increases simplicity and reliability by eliminating the clutter of many individual components including battery switches, secondary battery isolators, relays, load managers, low voltage alarms and cutoff’s, separate solar panel and wind generator voltage controllers, and more.
