Updated 30 A MPPT solar charge controller: the controller automatically identifies 12 V to 24 V batteries, with innovative MPPT technology, monitoring efficiency up to 99%, with temperature sensors, heat dissipation panels made of aluminium alloyRated charging current 20 A with module input voltage up to 60 V – Maximum photovoltaic power at 12 V, system voltage 290 W, 580 W at 24 V system voltage — Load output of 20 A directly on the charge controller; dimensions 100 x 113 x 60 mm4 charging modes: setting mode – manual switching on or off. Light control mode: turn on at night and turn off during the day. Working time of charge after sunset, working time of charge before dawn. Backlight control mode: auto on at sunrise and auto shut off in the dark.Intelligent protection: the charge controller has reverse polarity protection of the battery and solar panel, overcurrent protection, short circuit protection, overload protection, protection against open circuits, undervoltage protection, effectively prevents damage to the regulator.4-stage MPPT intelligent charging mode: fast charging, boost charging, float charging, balance charging. They effectively improve the charging speed and extend the life of the battery.
