This controller is a kind of intelligent, multi-purpose solarcharge and discharge controller. These serial products adopt customized LCDdisplay screen, which makes the operation on the interface rather convenient.All the controlling parameters can be reset flexibly to satisfy your differentneeds. This controller has the following features:

l   Visual LCD graphic symbol                                           Brief key operation
l  Automaticidentification system voltage level                   IntelligentPWM charge mode
l  Automatictemperature compensation                             Adjustablecharge-discharge control parameters
l  Settableoperating modes of loads                                 Overload& short circuit protection
l  Remotemonitoring and control function (custom)             Battery reverse-discharge protection
l  Batterylow voltage disconnection (LVD)                        Battery reverses connection protection
l  Accumulatedfunction of charge and discharge ampere hours

Three Load Working Mode:
24H—Normal Mode, in case of no fault state of the load is always in power.
1H~23H—Light Control with Time Control Mode, Load power after dark, and close the load according to the timer setting.
0H—Light Control Mode, Load on after dark, turn off the load after drawn.
Our solar controllers are designed for street light, solar home system.
Low Cost
Solar controller has specifically designed to meet the needs of the rural electrification market. The low cost resulted from using the latest electronic technology and high volume manufacturing.
High Reliability
We are manufacturer of solar charge controllers,power inverters,and solar power systems. All our products are designed for high quality and high reliability. The controller has a low failure rate and will last a long time, and got very good feedback from customers until now.
Electronic protections
The solar controllers are built-in electronic fused that do not require replacements.
Tropicalization
The solar controlers electronics are protected with moisture-tight coating, minimizing damage from humidity and from nesting insects.
Easy to use
Solar controller is fully automatic and requires no adjustments or user selections.
