High MOSFET Short

This can lead to fatal damages of battery, and equipment connected to it, as solar panels are directly connected to the battery.

Solution:

• Turn Low MOSFET permanentaly on to burn F2. L1 will smooth burn current and protect the MOSFET. When F2 burns, Inductor L1 will release very high EMF voltage.
• Use an additional MOSFET with Rds_os < 1mOhm to cut the PV or solar
