DC Solar Home Light System

DC Solar Home Light System


1. Automatic system voltage identification

2. Charging program options for sealed, GEL and flooded  lead-acid batteries and  lithium batteries are available.

3. An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery's service life (with the exception of GEL and lithium batteries).

4. With temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries).

5. A wide range of load working modes facilitate the product's application to different types of street lights and monitoring devices.

6. The product provides overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.

7. By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.

8. A range of parameter settings and power-down saving functions are available ,thus requiring no repeated setting.

9. The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.

10.The user-friendly design of browser and dynamic interfaces ensures convenient and intuitive operations.

11. (An optional communication function) provides a RJ12 data port (output of TTL232 level or bluetooth signals), with the data adopting the standard Modbus protocol, and can be used together with our upper computer monitoring

software or mobile phone APP.

12. Boasting an industrial grade design, the product can function well in various tough conditions.

13.TVS lighting protection is adopted.
