1. Rated voltage: 12/24V 2. Rated current: A 3. Maximum. Photovoltaic voltage: 50V 4. Max. Photovoltaic input power: 750W(12V)/1500W(24V) Function: 1. Always keep the battery at full voltage. 2. Prevent battery overcharging. 3. Prevent the battery from over-discharging. 4. Prevent the battery from reverse charging the solar panel during use. 5. Battery reverse connection protection 6. Solar panel reverse polarity protection 7. When the battery voltage is low, the controller will Automatically cut off system load. If the voltage is The battery returns to normal and the load starts working again. 8. protection 9. Depending on the battery voltage level, the controller can Automatically set charging shutdown voltage, load shutdown voltage, load recovery voltage. (This parameter defaults to 25℃ The condition is locked by the CPU program and cannot be adjusted. ) 10. The controller will automatically compensate for temperature The charging voltage changes according to changes in ambient temperature.
