This controller allows you to charge a 12Vdc battery bank using standard 250-390Wp 60cells poly- or moncrystalline modules. The fast MPPT controller will improve energy harvest by up to 10% compared to slower MPPT controllers.
Programmable options and auto 12/24V recognition
You can choose from two standard battery types - GEL and Liquid. Also, you can set a night-light function or low-disconnect voltage
LCD display with many features
Read real-time PV voltage , PV current, Battery voltage, Battery current or check historic data
Four-steps charging algorithm
Ensure a reliable, fast and safe charging with the four-steps charging algorithm
Many protections against various treats
Protections against: PV over current, PV short circuit, PV reverse polarity, Battery reverse polarity, Batery overvoltage, Battery deep discharge, Load short circuit, Load over current
Load output
Over-discharge of the battery can be prevented by connecting all loads to the load output (except for inverters). The load output will disconnect the load when the battery has been discharged to a pre-set voltage
Day/night timing
You can use this controller in street-lighting applications. It can automatically start a connected load (lights) at sunset and it can stop them at sunrise, or you can set the working hours of the lights during the night
A single controller can be used in various PV-configurations. Below are the most frequently-used ones. Several controllers can work in parallel.
