The DC fuse of photovoltaic cells is specifically designed for use in photovoltaic (PV) systems, mainly to protect solar panels. The breaking condition of solar panels is that while effectively breaking the faulty solar cell pack, it does not affect the operation of other normal working solar cell packs. The PV series DC fuse can safely protect the PV module and its conductors from the threat of reverse overload current, regardless of whether the DC power supply is threatened. With the increasing demand for high-power solar cell packs in the market, the use of high-voltage DC fuses to protect the safe grid connected operation of photovoltaic cell systems has become an important international technical measure.

We prioritize technological R&D, building automated digital production lines. Our professional laboratories include:

• Lightning Impact Test Room (8/20, 10/350, 1.2/50us)
• SPD Safety Laboratory (Thermal stability and TOV fault tests)
• Environmental Laboratory (Salt spray, vibration, temp tests)
• Low Voltage Test Room (Withstand voltage, flame retardant levels)

With over 10 years of experience, we have developed into a professional lightning protection technology company integrating R&D, manufacturing, and electrical solutions. Our facility spans over 30,000 square meters and employs over 200 people. We are committed to new energy electrical products and continuous innovation, holding various international certifications like ISO9001, CE, TUV, and RoHS.
