"Can I set and check whether the battery is in a lead-acid battery or a gel battery?
A: Regardless of any type of MPPT controller, our regular battery type (lead acid battery/colloid battery/rich liquid battery) can be viewed and set through the LCD display of the machine or APP or host computer;"If the main charging voltage is 14.7V, is the charging voltage also 14.7V or other lower voltage?
Answer: When the main charging voltage of the battery is set to 14.7V, the charging voltage of the controller will also be controlled within the range of 14.7V. Through the constant current charging mode CC→constant voltage charging mode CV→floating charging mode CF three stages Charging the battery, the charging voltage is equal to the battery voltage in the constant current charging mode CC, the charging voltage is equal to the set main charging voltage value of 14.7V in the constant voltage charging mode CV, and the charging voltage is equal to the set floating charging voltage value in the floating charging mode CF. Such as 14.5V;"
"Can the machine charge the golf cart acid battery?
A: Yes, the controller charging parameters are set according to the specific charging parameters of the battery (such as the main charging voltage value and the floating charging voltage value). "
"When the machine is turned off and restarted, is the parameter that remains set or will it return to the default setting?
A: My driver has a storage function. After the shutdown and restart, the machine still keeps the original settings;
"When the solar panel charges the battery through the controller and has a load output, does the energy used by the load come from the solar panel or the battery?
A: Priority is given to the electricity generated by the solar panel. If the solar panel power is insufficient, the battery is replenished; for example, if the load needs 50A and the solar panel generates 30A, it needs to be supplemented by 20A from the battery;
"What is the minimum PV input voltage? Why is there a repeated "charge-stop-charge-stop-" condition?
Answer: Each MPPT controller has a starting charging voltage point. As long as the PV voltage is higher than the starting charging voltage point, it can be charged. When the PV voltage is lower than the low voltage protection point, charging will stop; if the PV voltage is near the charging voltage starting point When it is easy to repeat the "charge-stop-charge-stop-" charging situation, such as in the morning or evening; if the system is in strong sunlight, there will be repeated "charge-stop-charge-stop-" charging situation. , then it is recommended that the solar panel working voltage is low, need to increase the number of solar panels connected in series;"
