100A/80A/60A MPPT/PWM Solar Charge Controller 12V/24V/36V/48V Auto Controller Tools Solar PV Battery Charger with LCD & Dual USB

2022 New MPPT/ PWM 60A/80A/100A 12V 24V 36V 48V AUTO solar panel charge controller with LCD Display Dual USB Multiple Load Control Modes New Mppt Technical Maximum Charging CurrentThe controller is 12/24/36/48V auto, but the voltage of the photovoltaic panels used to charge different batteries is different. For 12V batteries, use about 18V photovoltaic panels, for 24v batteries, use about 30-37V photovoltaic panels, and for 48V batteries use 60. For photovoltaic panels around -72V, the controller wiring is connected to the battery first, and then to the photovoltaic panel. Disconnect the wire on the contrary, otherwise it will easily cause damage to the controller! ! !Description of charging protection:1. When using a 12V battery, the boost charging voltage of the battery is higher than 14.8V, and it is converted to a floating charging voltage of 13.8V.2. When using a 24V battery, the battery boost charging voltage is higher than 29.6V, and it changes to a float charging voltage of 27.
