Product Description

Advantages and Benefits: *4V charging/discharge system. Compared with the *2V, by adopting of *4V system, the charging/discharging current is small and less wire losses, improved the reliability of the system. The charging efficiency increased 6%~*0%. Optimum PV gel battery. Our PV gel batteries are featured with low self-discharge, good consistence on deep discharge, long cyclic life and low floating charge voltage and current, free from erosion, pollution, gas escape and leakage. It is allowed to discharge deeply with wide temperature range from **0deg. To **0deg. Automatic light modulation by pre-setting function. Pre-setting function allows end user preset different light output at different period of time. Automatic Light modulation by monitoring capacity of battery. The controller can adjust output power to get longer operation time according to the actual capacity of battery.
