Isolated PV systems exposed to extreme weather/environmental conditions (streetlights, navigation buoys, etc.) have increased risk for damage to the power electronics. In order to assure reliable battery protection under such conditions, Phocos developed a fully encapsulated charge controller to prevent corrosion: CIS.

CIS is an industrial-grade charge controller that is suitable for all practical PV applications. It conforms to the IP68 protection system. Four-stage PWM-charging is combined with low-voltage disconnect, flexible load timer functions, and a multi-LED system status display. CIS is available in two versions:

SingleLoad version with dimming output (CIS): The CIS comes with a charge output and a control output for dimmable ballasted lamps.

The CIS has no moving parts, switches, or buttons. Settings such as battery type, deep discharge thresholds, timers, and other configuration items are made quick and easy by infrared remote control.
