【Protection】SPD main work is to protect electric DC Appliance against transient fault supply, extra current, unwanted current, overheat, over current and extra current send to earthing.
【Indications】SPD shows the colour of operating status: Green (normal) / Red (abnormal).
【Use】SPD mainly used for protected electrical appliance 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 Earthning 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. SPD are especially designed for DC or Solar Application and AC appliance also.
【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. SPD cuts the unwanted or extra current from any appliance.
