DC SPD Surge Protective Device 20KA 40KA Voltage Protector for Solar PV Systems

One lightning strike can destroy your entire solar investment — this DC SPD Surge Protective Device stops that from happening.

The amiciKart DC Surge Protective Device (SPD) is engineered specifically for solar PV systems, providing robust protection against lightning-induced surges and sudden voltage spikes that can permanently damage your panels, inverter, and charge controller. With a peak discharge capacity (Imax) of 40,000A and a nominal discharge rating (IN) of 20,000A, this SPD absorbs high-energy surge events repeatedly without degrading — keeping your ₹lakhs worth of solar equipment safe year after year.

What sets this device apart is its dual-sided installation design — place one unit at the solar panel end and another at the inverter end to create a complete protection barrier across your DC power lines. This is especially critical for rooftop and ground-mounted systems with long cable runs exposed to open sky. Built-in high-energy MOVs (Metal Oxide Varistors) with a thermal disconnector ensure the device safely cuts off if it reaches its thermal limit, while the visual failure indicator tells you at a glance when the SPD needs replacement — no guesswork, no hidden failures.

Suitable for residential rooftop setups, commercial solar farms, and off-grid installations, this SPD is a must-have safety component for any serious solar system owner.

Choose Your Variant

• 500V DC: Ideal for smaller residential PV strings and 12V/24V off-grid systems with lower voltage configurations.
• 600V DC: Best suited for mid-range grid-tied residential and small commercial solar installations.
• 1000V DC: Designed for large-scale commercial or industrial PV arrays running high-voltage DC strings up to 1000V.

Backed by a 1-year warranty and direct WhatsApp/email support from amiciKart. Free shipping across India, same-day dispatch on orders before 2 PM.

• Shields ₹lakhs of solar equipment from lightning & surges – high-energy MOV-based design with 40KA peak (Imax) and 20KA nominal (IN) discharge capacity handles repeated surge events without degrading protection
• Full-system coverage with dual-sided installation – mount at both the solar panel end and inverter end to protect the entire DC power line, especially critical for rooftop and ground-mounted systems with long cable runs
• Available for all common PV string voltages – choose from 500VDC, 600VDC, or 1000VDC variants to match your exact solar array configuration
• Safe, fail-safe operation with built-in thermal disconnector & visual indicator – thermal cut-off automatically isolates a faulty MOV, while the colour-coded status window tells you at a glance when the SPD needs replacement
