Li Ion PWM Solar Charge Controller
SSN Digital Solar Charge Controller 20a 12/24v off grid for Li-ion
Function:
1. 12V/24V Automatic identification by system
2. LED digital display and one-key operation, easy to use
3. The improved 3-section computing method can weekly give the battery a
Balanced charging. It can stop the battery from being unbalancing and vulcanizing
and let the battery been used for more time.
4. the controller is equipped with the serial PWM charging main circuit with
additional 3%~6% efficiency than the non-PWM circuit which can work for more
time and increase the using period of the system.
5. Controller has three load work ways and can be easily used in varies streetlights
and monitors.
6.Visualized LED display which can let the users get to know the conditions of
solar power and storage battery.
7. Overcharge, over discharge and overload protection; Electronic short circuit
protection; Reverse connect preventing protection.
8. Lightning prevention.
