Working Modes (listed)
- 1. Charging mode: in any case, never discharge.
- 2. Light control mode: when nights are detected, delay 10 minutes then start to discharge; when daytime is detected, delay 10 minutes then stop discharging.
- 3. Light and time delay control mode: when nights are detected, delay 10 minutes then start to discharge and count down; discharge stops when timer reaches 00:00. Longest duration is 23:59.
- 4. Universal control mode: under trouble-free condition, always keeps discharging.
- 5. Manual control mode: uses “▼” for discharging on/off.
- 6. Timing control mode: opens or closes the discharge regularly.
- 7. Test mode: same as light and time delay control mode but without the 10-minute delay.
Additional listed behavior: the controller can continue discharging under low voltage protection by touch-holding “▼” for 5 seconds; discharge is then only stopped by hand. This may damage the battery if used improperly.
Installation Notes & Precautions (listed)
- Correct installation sequence: (1) Battery --> (2) Solar panels --> (3) DC load.
- To correctly identify battery voltage during first wiring: 12V battery voltage higher than 10V; 24V battery higher than 20V; 36V battery higher than 30V; 48V battery higher than 42V.
- Do not charge 12V batteries with 24V/36V/48V solar panels; excessive difference may cause overheating and damage.
- Install the controller as close to the battery as possible to reduce voltage drop caused by long wires.
- Use only photovoltaic panels as the charging source; do not use DC or other power supply as the charging source.
- The controller will generate heat when running; install on a flat, well-ventilated surface.
- Listed battery note: suitable for lithium batteries and various lead-acid batteries; lithium batteries require manual adjustment of overcharging voltage. Do not use other batteries (e.g., nickel metal hydride batteries).
Applications
- Communication base station
- Home power supply system / home solar system
- Traffic light
- Solar street lamp / street light
- Courtyard lamp systems / lamps management
- RV system
- Yacht
Troubleshooting (listed)
| Malfunction phenomenon | May cause | Troubleshooting method |
|---|---|---|
| Sunshine is sufficient but not charging | Photovoltaic board open circuit or reverse connection | Re-link good photovoltaic panels |
| The load logo does not light up | Mode setting error / The battery voltage is too low | Re-set / Recharge |
| Load mark flashes slowly | Load overcurrent | Reduce load power |
| Load logo flashes quickly | Short circuit protection | Remove short circuit, automatically recover |
| The controller does not light up | The battery voltage is too low / reverse connection | Replace the battery / check reverse connection |
