I cannot overemphasize the importance of these guys.
You cannot have a multi-million currency business and mount guards to protect your investments. The same is applied to this solar system and these are the guards that constantly check if everything is going as planned. They analyse the electrons passing through the system and only give access to those qualified.
• DC (direct current) surge protector for preventing fire outbreak (especially during a thunderstorm). It is connected to the ground (earth).
• Solar panel circuit breaker for any abnormality with the solar panels. This disconnects the panels from the inverter's mppt system.
• Battery circuit breaker for any abnormality with the battery.
• AVR (Automatic Voltage Regulator) to check the input alternating voltage from grid and disconnects if the voltage is too high or too low (Protecting the inverter from overheating and getting damaged).
• Ac input circuit breaker for protecting the input of the inverter system excess alternating current from the grid.
• Ac surge protector for preventing fire outbreak from abnormality from the grid. It is connected to the ground (earth).
