The controller adopts the leading PowerCatcher maximal power Tracking technology in the industry to achieve maximal energy Tracking for solar panel, so that it can quickly and accurately trace the MPP of the solar battery, acquire the maximal energy of the solar panel and significantly improve the energy utilization ratio of the solar system. Widely applied to solar off-line photo voltaic system for managing solar panel and storage battery in operation, the controller is the core control component of off-line photo voltaic system.
The inside of the controller possesses sound electronic failure detecting and protection function to avoid the product component damage caused by installation error and system failure.
The controller is equipped with an LCD display screen to simultaneously support data interaction, setting and other operations with mobile phone APR PC upper computer and other devices.
1. Automatic identification system voltage
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, 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 lightings protection is adopted.
