Lightning Protection：Maximum discharge current 40KA
Circuit Breaker：Maximum current output 32A
Independent Fuse：15A per input ISC
Installation and precautions:
1. Regularly check the high-voltage fuse to prevent the solar panel from disconnecting after the high-voltage fuse is blown.
2. The input and output of PV cannot be reversed, otherwise it may cause the equipment to fail to work, or even damage other equipment.
3. When testing or waiting for this device, please note that the input and output ports may be live, please avoid electric shock or damage to other devices.
4. Check the lightning protection module after lightning. If the error light on the control panel turns red, replace it in time.
