MPPT charge controllers - ProStar PS

The Prostar MPPT™ solar charge controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1100 watts. This controller allows two modules in series on a 12V battery system and two or three modules in series on a 24V battery system. Detailed battery programming options allow for advanced battery support for the latest Lithium, Nickel Cadmium, and Lead Acid battery types.


High reliability: conformally coated circuit board and corrosion resistant terminals

Maximizes energy harvest: using TRAKSTAR MPPT™ technology to determine and adjust to the true maximum power point as insolation changes throughout the day

Data logging: detailed logging of power and load data confi rms performance and helps isolate system inconsistencies

Automatic PV Based Lighting Control: multievent load control enables powerful options for PV lighting systems and settings can easily be adjusted in the fi eld

Modbus communications: Solar Industry Standard MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization with other system hardware

High strength: Polycarbonate Case and extruded aluminum heatsink

Self diagnostic: The ProStar MPPT continuously monitors and reports any internal hardware issues or system problems through its status LED’s, optional display or communication port
