Surge Protection for Solar Photovoltaic (PV) System
The SUP4 series Surge Protection are designed to protect against lightning surge voltages in photovoltaic power supply networks.
These units must be installed in parallel on the DC networks to be protected and provide common and differential modes protection. The SUP4 series is available for the main operating voltages in photovoltaic: 1000 Vdc.
The use of SUP4 series Surge Protection is recommended at both ends of the DC power supply line (solar panel side and inverter/converter side),
Especially if the line routing is external and long. The electrical diagram of the SUP4 series is based on high energy PV equipped with specific thermal disconnectors and related failure indicators.
The SUP4 series is made with plug-in modules to allow a fast and easy maintenance in case of failure (disconnection from the DC network).

Product Details ShowApplicationSPD is used to protect all kinds of electrical equipment in the power system from lightning over-voltage, operation over-voltage, power frequency transient over-voltage impact damage to an electrical appliance
The electrical circuit or communication lines because of outside interference peak current or voltage suddenly, the surge protector can in a very short time conducting shunt, so as to avoid damage to other equipment surge in the loop Installed front of inverter input and back of inverter output Installed in Parallel the spd is installed in the electric circuit with parallel, the first to play a protective role, the response time in the 25 to 50 nanosecond
AdvantageFirst factory produce 1500V SPD, approved TUV certificate at EN50539-11 standard.
Every pole achieve 1500V, 1200V, 1000V, 500V.
PPT material cover. Anti flame.
Use Longke chip from Taiwan. Material Zinc oxide.
With specific thermal disconnects and failure indicator(visual indicator/ optional): green-good, red-replace
Remote control: with signal contact
Plug-in module
Life: 50 times
