Industrial MPPT Solar Charge Controller with LED Driver

Compatible within CIS-series (IP68) and CIS-CU, MXI-IR, CISCOM


For industrial application

highest efficiency, up to 98% in charging process

ready for extreme conditions (IP68) waterproof

max DC input 85V and 15A

integrated 2-years datalogger

With innovative maximum power point tracking technology, this Phocos MPP tracker ensures maximum performance and yield from a variety of solar systems.

The use of MPPT technology can contribute to a considerable boost in power output from PV modules (up to 30% more). Especially in moderate/colder climate areas where PV module voltages tend to be higher.

At the same time, the temperature-compensated, three-stage I-U curve charge control algorithm significantly extends battery lifespan.

The integrated datalogger (2 years period) provides an insight into system performance, displaying important information such as system status, voltage, current, SOC, etc.

Perfect for all PV solar outdoor commercial applications, withstands hardest outdoor conditions in: PV solar street lights and park lights, in commercial measuring and control systems.

Why to use MPPT charge controller ?

They are two fundamental reasons: system efficiency and applicable for big PV panels.

Because they allow PV modules to operate at their higher optimum voltage in varying light conditions: summer, winter, morning, noon, cloudy etc. The MPPT charge controller takes the voltage output of the solar panels and compares it to the battery voltage. It figures out what is the best voltage to get maximum current (A) into the battery. Or said in another way, the MPPT controller tracks the best voltage level and then down converts it to the voltage of batteries. MPPT (Maximum Power Point Tracking) charge controller calculates in real-time the optimal charging parameters, continuously by its internal algorithmMPPT tracking of the optimal power point, improves performance by as much as 30% (annual energy production), compared with the PWN charge controller. 
PWM (Pulse Wide Modulation) charge controller, works based on 1/2/3 or 4-stage charging method (switching between constant stages according to the occurring PV voltage and current).

The MPPT charge controller are most effective in following conditions:

in cold weather, cloudy or hazy days (fall/winter/spring) and in low temperature conditions. PV module works better at cold temperatures and MPPT is utilized to extract the maximum power available from the module

when battery is deeply discharged: MPPT can extract more current (A) and charge the battery, if the state of charge in the battery is lower.
