Solar Panel Charge Regulator Controller 12v PV Regulator With LCD
Screen
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.
Advantage:
1. IP32,Strong and durable aluminum case
2. 12V/24V automatic recognition
3. Remote(infrared) Unit to configure,with LCD display
4. External temperature sensor, automatic temperature compensation
5. PWM voltage regulation use 3 stages of charging way
6. Battery type and protection level selection
7. Full automatic electronic protect function
8. 5 stages time could be adjusted
