Solar protection devices are small but must have devices that will protect your solar components like solar panelsolar inverter, as well as complete DC circuit from harmful conditions. These protection devices may be small in size but they can save you from loss of lakhs. These devices can be classified by their nature, function and way of protection.

There are many different types of solar protection devices available in the market like SPD, DC MCB, DC Fuse, ACDB, DCDB, etc. Each of them have their own specific role. Some devices will trip, some will ground the extra current, and some will blow up on their own to save your solar system. So let’s dive into it and know more about these protection devices.

#1. Solar SPD

A surge protection device (SPD) shields your electrical installation from transient overvoltage or electrical power surges by redirecting the current to the ground via earthing. Briefly, it diminishes the effect of a surge and prevents the installation from getting damaged. 

An SPD protects the electrical wiring, accessories, consumer unit and other sensitive electronic gadgets. Hence, it reduces the risk of damage and instant failure to the electrical equipment.

Why do you need an SPD?

Whenever the voltage increases in an electrical line wheather it is DC line or AC, it significantly resulting in damaging the wiring insulation and electrical gadgets. 

Hence, the electrical installation at your premises needs to be protected against overvoltage to prevent the following consequences-

  • Interruption in services or activities
  • Damage to electrical gadgets connected at the time of power spike
  • Damage to cultural heritage
  • Serious injury or loss
  • Damage to the surrounding 

Hence an SPD is mandatory to reduce the safety risk factor.

#2. DC MCB

A DC MCB is a solar protection device that is used in DC circuits to protect the appliances from over-current. The device optimises the flow of current and ensures complete protection against short-circuiting.

The voltage used in DC MCB is direct current states. It automatically senses the spike in ampere and trip within seconds to break the DC circuit. Talking about the physical parameters of the device, the DC MCB are equipped with green and red colour indicators.

#3. AC MCB

An AC MCB is the circuit breaking device used in AC circuits to ensure safety in case of overload or short-circuit. Its terminals are marked as LOAD and LINE and they can be extinguished easily without crossings. 

AC circuits carry varying currents. Hence, it is necessary to use an AC MCB in particular with such a circuit. A DC MCB cannot work here.

#4. DC Fuse & Holder

A DC fuse is a small lightweight solar protection device used for opening and breaking the DC circuit when it exceeds the limit. In case of supply disturbance, the fuse blows itself and breaks the circuit automatically ensuring the system’s safety.

A DC fuse holder is a small gadget that holds the DC fuse. It is mounted in the accessory and is available in different types. Mostly, the tool is manufactured along with the fuse.
