PWM solar charge controller HP series30A/40A/50A/60A

SR-HP series is a PWM charge controller with LCD is mainly for rural Electrification and solar home power systems application. It is included HP2430/HP2440/HP2450/HP2460/HP4830/HP4840 models.



1. Automatic identification of system voltage.
2. Support charging gel batteries, sealed batteries, lead-acid batteries and lithium batteries, etc.
3. An upgraded 3-stage PWM charging algorithm is adopted. Overdischarge or application of an equalizing charging to the battery regularly can effectively prevent the battery from non-equalization and sulfuration and extend the lifespan of battery.
4. Featuring a temperature compensation function, the controller can automatically adjust charging parameters.
5. A variety of load working modes which facilitate the product's application to different types of loads.
6. The product provides overcharge, overdischarge, overload, short-circuit and reverse connection protection.
7. Advanced startup method of load: Large capacitance loads can be started smoothly.
8. The product adopts a dot-matrix graphic LCD screen and a human-machine interface with two switches.
9. The humanization design of interface ensures users can use the product conveniently.
10. The controller provides a RJ12 data port (output of TTL232 level or bluetooth signals.) It supports standard Modbus protocol and can achieve data interaction with APP on mobile phone.
11. With an industrial grade design, the product can function well in various tough situations.
12. TVS lightening protection is adopted.
