This manual mainly introduces the characteristics, usage and technical specifications of the PJRC series solar controllers.
This manual provides detailed instructions for installing and using PJRC solar controllers (models PJRC5I, PJRC10I, PJRC15I, PJRC20I). It includes wiring diagrams, panel layout, and step‑by‑step setup procedures for solar DC power and solar street‑light systems.
The document also describes the controller's features such as PWM charging, programmable modes, temperature compensation, and built‑in protections (overload, short‑circuit, reverse polarity). Fault indicators, mode selection, and maintenance tips are explained to help users achieve optimal battery performance and longevity. This manual is written in Chinese.
| Rated charging current | 5A (PJRC5I), 10A (PJRC10I), 15A (PJRC15I), 20A (PJRC20I) |
|---|---|
| Rated load current | 5A (PJRC5I), 10A (PJRC10I), 15A (PJRC15I), 20A (PJRC20I) |
| System voltage | 12 V or 24 V/12 V AUTO |
| Overload protection | 1.25× rated current for 60 s, 1.5× rated current for 5 s |
| Short‑circuit protection | ≥3× rated current |
| No‑load loss | ≤6 mA |
| Charging circuit voltage drop | ≤0.26 V |
| Discharge circuit voltage drop | ≤0.15 V |
| Operating temperature (industrial grade) | -35 °C to +55 °C |
It indicates that the system voltage is over‑voltage and the controller is in a protection state.
Press the switch button once and wait about 30 seconds; the controller will restore normal output.
The PJRC10I has a rated charging current of 10 A.
