This controller uses the most advanced MPPT technology to ensure high efficiency (>95%) of your solar system. Significantly outperforms standard PWM controllers. Remote meter with 5m cable displays key charging parameters e.g. voltage, current and the state of the battery charge. It can also record accumulated charge and discharge energy, as well as min / max voltage. Multiple possibilites for system personalisation: the unit allows you to choose battery type and capacity, change charging volts/ duration of each charging stage, define your own battery type and amend load work mode Comprehensive set of electronic protection functions e.g. stops reverse current at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection. Current limiting function (40A) allows possibility of adding more solar panels in the future. Scroll down to Product Description for more details about this product…
