Professional MPPT controller designed for charging 12 / 24 V lead-acid and
LiFePO4 batteries with solar energy. Compared to cheaper PWM type loss
regulators, these regulators achieve much higher efficiency (up to 98%) and
ensure maximum energy yield from solar panels. AGM, GEL and LiFePO4 sealed
batteries are supported, the voltage is detected automatically. A comprehensive
LCD display shows voltage of the solar panels and the battery, charging current,
state of charge, load current, temperature or error code in case of a fault. At
the same time, a thermocouple for charging temperature compensation is included.
The connected DC load can be switched manually by the controller or simply
programmed (e.g. twilight switching with a timer). A sophisticated protection
system prevents the controller, solar panels and battery from damage or
incorrect connection. - MPPT technology for monitoring the maximum performance
of the panels - adaptive multi-stage battery charging - automatic detection of
12 / 24 V - support for lead AGM / GEL and LiFePO4 batteries - advanced battery
and panel protection system for higher safety - TVS lightning protection - clear
LCD display, LED indicators of operating status - programmable DC load switching
- absolutely silent passive cooling - sensor for charging temperature
compensation - communication port for monitoring Technical parameters Battery
