High quality PWM 12V 24V solar panel charge controller 50A off grid system solar charge regulator
Model number: HP2450-PWM-LCD
50A charging solar controller is designed for off-grid solar system, such as street light, solar home system or small power station etc. It has LCD display, reliable battery charging , full electronic protection, and programmable parameters.
1.HP2430-PWM-LCD,12/24V,30A(for both PV and loads)
2.HP2450-PWM-LCD,12/24V,50A(for both PV and loads)
1.12V/ 24 V or 48V system voltages are automatically recognized.
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.Different working mode option.
6.The product provides overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.
7.A range of parameter settings and power-down saving functions are available ,thus requiring no repeated setting.
8. The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.
9.The user-friendly design of browser and dynamic interfacesensures convenient and intuitive operations.
10.(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.
11.TVS lighting protection is adopted.
