Solar Charge controllers are vital components in battery-based PV systems, keeping the PV array from overcharging the batteries and optimizing charge current. QW 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.
