Phocos CX40 Charge Controller 12/24 Volts

The CX series is a sophisticated solar charge controller family with exceptional features in this price range. Beside a perfect PWM regulation with integrated temperature compensation the controllers provide extraordinary display, programming and safety functions.

The battery state of charge is clearly displayed with a bar chart, as well as energy flows from and to the battery and the load status (e.g. overload, load short circuit). The deep discharge protection function can be set up to three different modes: voltage controlled, SOC controlled or adaptive (fuzzy logic).

Acoustic warnings are built in, also a programmable nightlight function. As an accessory we can provide an Excess Energy Management output to control special Phocos appliances like the SF solar refrigerators/coolers. The compact case design is prepared for DIN rail mounting (mounting device available as an accessory).

NOTE: This charge controller can be ordered for Negative grounded solar PV systems. Please contact us for more information.
