Solar Charge controllers are vital components in battery-based PV systems, keeping the PV array from overcharging the batteries and optimizing charge current.
A series solar controller is superior in quality and compatible with most types of solar inverters. It has all-around protecting functions and MPPT function for better charging the battery and protecting electrical devices. The mutual operation feature helps user regulate the charging current, charge-off voltage, etc. The efficiency is 15%~20% more than early-developed charge controllers.
Features:
1. CPU controlled with MPPT function: able to adjust the charge current and decide if to supply the loads electricity according to the voltage of battery;
2. Compensation charging: according to various system temperatures, the controller will automatically compensate the temperature of the charging voltage;
3. LCD monitor: showing the charging current, battery voltage, environment temperature and real-time data of the charging process;
4. Temperature sensor: probing the temperature of environment and indicating the degree of charging.
