Steps for Adjusting Parameters of MPPT Boost Charging Module: 1. The module input is connected to the solar panel to ensure that the sun shines on the solar panel.
2. The output of the module is no-load, and the volta of the multimeter is connected to the output of the module, according to the volta when the battery is fully chard.
Volta value (refer to the label on the back of the charr), adjust the CV potentiometer to the desired volta. Note: If the module does not boost, please turn the MPPT potentiometer 20 turns clockwise before adjusting the output volta.
3. Connect the battery to the output of the module, and then connect the volta of the multimeter to the input of the module.
Adjust the MPPT potentiometer to a multimeter showing a volta close to the maximum power point volta of the solar panel. Refer to the maximum power point volta on the label on the back of the solar panel. nerally, a lower volta than the marked volta can obtain a larr charging current. For example, if the MPPT value of the 18V board is adjusted to 16-17V, the current will be larr than that of 18V. You can also connect an ammeter in series to call back and forth the MPPT potentiometer to stop the charging current at the maximum point.
4. If you need to use a smaller current for charging (for example, the power of the solar panel is relatively lar, and
The battery capacity is relatively small). When the sun is relatively lar, connect the current ar of the multimeter in series between the MPPT charr and the battery, and adjust the CC potentiometer to the required current.
Notice: 1. The potentiometer used to adjust the parameters is multi-turn, and there are 28 turns from the minimum value to the maximum value.
Clockwise the volta or current increases and counterclockwise decreases.
2. If there is sun, the output volta of the charr cannot be adjusted, or the
If the battery has no charging current, please turn the MPPT potentiometer clockwise for more than 20 turns and then repeat step 3.
3. The input of MPPT charging module should be connected to battery or switching power supply for charging or boosting module.
time cost. Please adjust the cC potentiometer according to the level of the output volta to limit the output current to prevent over-power use, which will cause the charr to overheat or burn the power tube.
