Best DC SPD Brand in India
The right DC Surge Protection Device safeguards solar systems from sudden voltage spikes and lightning surges. Choosing a trusted brand ensures long-term safety, durability, and reliable performance.
Best DC SPD Brand in India
India is changing its electrical landscape with the expansion of renewable power, smarter homes, and more electric vehicles. As solar power and energy storage has become common, DC SPDs have also become an important safety mechanism. These equipments will prevent harmful current and lightning strokes that result in damaging voltage dips to sensitive equipment due to lightning strokes, switching activities and other forms of transient overvoltages.
As demand grows, the process of choosing the best DC SPD manufacturing brand in India cannot be understated. In 2025, one name that installers, industries and households will rest assured in choosing is Blitz Electrical. Blitz Electrical is designed and and constructed in India and trusted across the globe. Blitz has the highest performing, certified DC SPDs, with reliability, affordability and innovativeness across the spectrum of DC Surge Protection Devices.
What is a DC SPD and Why Do You Need It?
A DC Surge protection device is a safety device to protect a DC system such as a solar PV plant, battery energy storage, and EV charging network. In contrast to AC SPDs, which protect alternating current systems, DC SPDs are specifically optimised to protect direct current systems where the voltages are usually higher and the risk bigger.
Why DC SPDs Are Crucial in India
- Solar Energy Boom – India is the world’s third-largest solar market, with millions of rooftops adopting PV systems.
- Battery Storage Growth – Energy storage systems are gaining importance for uninterrupted supply.
- EV Charging – The increased popularity of electric vehicles means safe charging infrastructure is a necessity.
- Lightning & Grid Instability – more storms and an increase in surges, so surge protection is necessary.
A DC SPD provides protection against even one single surge could wipe out a panel, inverter and/or batteries with potentially an even bigger costly disruption.
