The new VPU PV surge protection device has excellent short-circuit impedance, such as connecting multiple solar panels in series in a photovoltaic system, and it can withstand a maximum short-circuit current of up to 11kA, even if no additional protection products are configured.

DPM200 Photovoltaic systems are often installed at high altitudes of up to 4000m. Weidmuller’s surge protectors provide reliable protection for photovoltaic systems, even in such open-air environments. Typically, a derating risk assessment is required for PV systems installed at these high altitudes, and this additional assessment step is not required with Weidmuller’s surge protectors.

It should be emphasized that the surge protection of the photovoltaic system cannot be ignored, which involves the two core links of the direct current (DC) side and the alternating current (AC) side, both of which need to be configured with special surge protection equipment to ensure the safe and stable operation of the entire system. With more than 20 years of surge DPM200 protection experience, Weidmuller offers a comprehensive range of surge protection products for direct current (DC) and alternating current (AC). These highly effective lightning and surge protection products can effectively extend the service life of electronic products in photovoltaic systems and AC application installations, and are essential for achieving long-term stable energy production.
