Y&H 20A MPPT Solar Panel Charge Controller 12V/24V Auto MAX 50V PV Input for GEL SLD FLD LI User Battery Voltage Regulator

Bi-peak MPPT technology accurately locks the maximum power point, so even if the PV module is blocked or damaged, it can still generate power efficiently. Compared with traditional PWM, MPPT charging efficiency is increased by about 25%, overall efficiency is up to 99.9%, and circuit conversion efficiency is up to 98%, maximizing the use of PV energy. Solar controller automatically recognizes 12V/24V battery voltage, compatible with GEL, SLD, FLD, LI, User, and supports 0V charging of Li-ion batteries, ensuring stable adaptation of various battery types and waking up the sleeping Li-ion batteries. LCD real-time monitoring of the system status, accurate identification of faults, intuitive display of abnormal information, to facilitate rapid troubleshooting and maintenance, improve system reliability. Adjust the charging and discharging parameters according to the ambient temperature to extend the battery life. All-round electronic protection, to ensure the safe and stable operation of the system. When the solar panel power is too high, automatically adjust the charging current to ensure safe operation. MPPT solar controller is suitable for home photovoltaic systems, RVs, yachts, communication base stations, outdoor monitoring, power supply for electric equipment and other applications.
