MPPT: Maximum Power Point Tracking

The MPPT controller utilizes Solar Maximum Power Point Tracking (MPPT) technology to extract maximum power from the solar array. The tracking algorithm is fully automatic and does not require user adjustment. MPPT technology tracks the array maximum power point as it varies with weather conditions, ensuring that maximum power is harvested from the array throughout the course of the day.

Before changing the controller

1. Reconnect the controller first.
2. Remove the normal street light controller. Connect it to the bad one and see if it is normal.

UNUSUAL

1. Battery
(1) Short-circuit charging between photovoltaic panels and batteries (1~2 days)
(2) Measure with a multimeter
2. Check the lamp head
(1) The lamp head will be on if the voltage is directly connected to the battery
(2) Booster requires 2 batteries
3. Photovoltaic panels (this is generally not bad)
(1) Quantity voltage
(2) There will be sparks when the positive and negative poles touch each other (1~2 seconds)

Solar Controller Wiring Instructions
Wiring sequence:
1) Connect the load first, and then connect the battery, the idle indicator of the controller is on, and after waiting for 30 seconds, the load will be on;
2) Finally connect the solar panel, wait for 70 seconds, the controller enters the charging state, the charging indicator of the controller lights up, and the load is turned off. If you wire it at night, the controller won't go into charging and the load will work all the time.
3) After wiring, please wrap the wiring head with waterproof tape to prevent water from entering.

Optional function introduction

1. Energy saving mode:
The controller automatically reduces the output power of the load according to the remaining capacity of the battery, thereby extending the working time of the load. For example: Set the take-off and drop-off voltage of the drop power to 125V, the termination voltage to 11V, and the termination voltage output power percentage to be 30%.
When the battery voltage > 125v, the load works according to 100% of the set power. When the battery voltage is between 125V and 11v, the controller will reduce the output power according to a certain proportion. When the battery voltage drops below 11v, the controller will Output a small discharge power (discharge current is 25mA) and keep it until the battery undervoltage. (The power reduction curve is shown in the figure below)

2. Morning light mode:
The morning light mode can only be checked when the controller is set to 3 periods or 4 periods. The morning light mode means that the controller automatically adjusts the working time of the load according to different night lengths, and finally enables the load to turn on the lights in the evening and turn off the lights in the daytime throughout the year.
