PWM 48V Solar Charge Controller Auto PV Solar Charge Controller SR HP4840

Features of SR-HP2430/2440

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 lighting protection is adopted.

Application
Solar Station System
Solar power station systems are typically used for regional centralized power supply, such as village, island, fields monitoring and so on. Also the power level range is between kilowatts to hundreds kilowatts.

Solar Home System
Solar home system are typically used for home photovoltaic power generation system, to solve electricity demand of none power or unstable power region. Also the power level rage is between hundred watts to kilowatts.

Solar RVs/Vessels System
Solar RVs/Vessels system are typically used for reducing the RVs and the vessels electricity cost, by setting up solar system to assist gasoline/diesel power generator.

Solar Street lights System
Solar Street lights System are typically used for street lightning of cities, villages, the intelligent streetlight system will remote monitoring all street lamps to reduce the operation and maintenance costs of system.

Hybrid Energy System
The Hybrid energy system contains solar, wind, diesel and city electricity energy system. The system will meet the load demand of electricity in villages, islands, and telecom stations to reduce the system cost and improve the replenishment ratio of system.
