Listed at 125.99 USD. 80A MPPT Solar charge controller 12V/24V/36V/48V Auto 80A MPPT solar controller parallel function: 80A MPPT solar charge controller Warm Tips: 1; Sequence of connecting the solar controller: first connect to the battery; then connect to the PV system; finally connect to the load device. 2; Do not connect inverters, wind turbines or AC chargers to the charge controller! Please connect the solar controller to the battery. 3; If the PV input voltage is less than 3V or less than the battery voltage. It may be seems to have been set. 4; Parameter setting: floating voltage > turn on low voltage again > discharge low voltage. 5; If the controller makes a buzzing sound because the controller is giving off heat. It will stop when the temperature returns to normal. 6; Make sure that the positive (+) and negative (-) terminals of the battery do not touch. 80A solar charge controller parameters: Lim ited Current Protection 80A System Voltage 12V / 24V / 36V / 48V auto Max PV Input Voltage 150VDC Max PV Input Power 1200W/12VDC;2400W/24VDC;3600W/36VDC;4800W/48VDC 3 Charging Mode Constand Current (mppt), Equalizing Charge, Floating Charge 80A solar controller Rated solar charging current: 80A Automatic 12/24/36/48V battery system 150Voc max PV input voltage MPPT solar controller By using an intelligent MPPT algorithm, the solar charge controller can extract the maximum power from the solar system by determining the maximum power point of the system.
