Solar DC SPD and AC SPD (Surge Protection Deviceis increasingly becoming popular in solar world. An SPD is a device that is designed to protect our equipment from the effects of power surges, spikes and other electrical disturbances.

Since the electrical circuits can be AC and DC, the SPDs can also be categorized as AC SPD and DC SPD. They are now being used by companies as well as individuals who have solar panels installed at their homes.

An SPD device requires proper earthing to function and protect the appliances. They work by providing a path for the electrical current to flow through them and then diverting the spiked or extra voltage to the ground via earthing/ground wire.

When a power surge occurs, excess voltage is diverted away from your sensitive electronic equipment such as computers, televisions and other devices.

Price List of AC & DC SPD

The price of any solar protection device depends on its type, power rating and solar brand. However, Kenbrook Solar is providing DC and AC SPDs at very affordable prices. You can see the prices below.

What is AC & DC SPD?

The function of an SPD is to protect the circuit from current spikes. But since the circuit can be AC or DC, it requires different SPD to serve the same purpose. In simple words, an AC circuit needs an AC SPD while a DC circuit can be protected with a DC SPD. 

  • AC SPDs provide protection to the AC power circuits and are used for home appliances and other electronics.
  • DC SPDs protect the DC power circuits and are used for solar panelssolar battery, etc.

Frequently Asked Question

It diverts extra DC voltage generated by solar panels to the ground via earthing and protects our DC circuits.

For complete protection of your AC & DC components, SPDs are important. However, they are not mandatory.

An AC SPD protects AC circuits and all sensitive appliances from voltage strike and other electrical disturbances. It diverts the surges to the ground to serve the purpose.

The price of SPDs are mentioned below:

  • 320V AC SPD = Rs. 799
  • DC 600V SPD = Rs. 799
  • DC 1000V SPD = Rs. 1249

SPDs are to handle power surges and they divert the excess voltage to the ground. But they aren’t circuit breakers. For complete protection, you must install MCB along with SPD.

Yes, to protect your AC as well as DC components and circuits, you need both types of SPDs.

An AC SPD deals with AC (alternative current) power and protects your electrical load/components, while a DC SPD works with DC (direct current) power and protects solar components.
