【Protection】SPD main work is to protect the electric DC Appliance against transient fault supply, extra current, unwanted current, overheating, over-current and extra current sent to earthing.
【Indications】SPD shows the colour of operating status: Green (normal) / Red (abnormal).
【Use】SPD is mainly used for protected electrical appliances and you cannot install SPD if you have not installed Earthing.
【Easy to Use】SPD full form is Surge Protection Device. It is Pluggable Design that is very easy to replace. You cannot install SPD if you have not installed Earthing and SPD sends extra currant to Earthing.
【Why to Install SPD】The unique weather makes the solar power plant vulnerable to overvoltage surges from lightning strikes and static discharges. The greater challenge is to protect these installations from direct and indirect lightning strikes that present a high risk of damage.
【Reason to Install SPD】To prevent high power from passing through the electronics appliances and causing high voltage damage to the PV system, the SPD must have installed. To do this, all conductive surfaces must be directly grounded and all wiring entering and exiting the system (such as Ethernet cables and AC mains) must be connected to ground via a surge protection device.
