1. Overcharge protection: When the charging voltage is higher than the protection voltage, the battery is automatically turned off to charging. When the voltage drops to the maintenance voltage, the battery enters into the floating state. When the voltage is lower than the recovery voltage, the floating charge is turned off and the charging state is entered. .
2. Over-discharge protection: When the battery voltage is lower than the protection voltage, the controller automatically turns off the output to protect the battery from damage; when the battery is recharged, it can automatically restore the power supply.
3. Over-current and short-circuit protection: After the load current exceeds 10A or the load is short-circuited, the fuse is blown and can be used after replacement.
4. Overvoltage protection: When the voltage is too high, the output is automatically turned off to protect the appliance from damage.
5, with anti-back charge function: the use of Schottky diodes to prevent the battery from charging the solar battery.
6, with lighting protection: When a lightning strike occurs, the varistor can prevent lightning strikes and protect the controller from damage.
