DC SPD Surge Protective Device

A DC SPD Surge Protective Device is the most critical safety component for any solar power system in Bangladesh. It protects your inverter and solar panels from high-voltage spikes caused by lightning or grid switching. At Solar House BD, we provide industrial-grade SPDs that divert excess energy to the ground in nanoseconds. You can find these safety devices at our shop in 268 Nawabpur Complex. Installing a high-quality DC SPD is the best way to ensure your solar investment lasts for decades without damage.

Types and Features of DC Solar SPDs

We stock different classes of protection to suit every need. The Type 2 DC SPD Surge Protective Device is the most common for residential setups, while Type 1 is used for direct lightning protection in high-risk areas. Our SPDs feature a Maximum Discharge Current (Imax) of 40kA to 60kA, ensuring they can handle massive surges. These units pair perfectly with our Sorotec 8kW inverters or Growatt lithium systems. They also come with a visual indicator that turns red when the device needs replacement.

Technical Specs and 1000V PV Integration

The DC SPD Surge Protective Device is available in various voltage ratings, including 500V, 600V, and 1000V DC. It is designed for DIN-rail mounting, making it easy to install inside your DC Combiner Box. With a fast response time of less than 25 nanoseconds, it clamps the voltage to a safe level before it can reach your sensitive electronics. For the best performance, we recommend using high-quality earthing cables and rods from our shop. Visit Shop 151 on the 2nd Floor to choose the right voltage rating for your specific solar string.
