Surge Protection Device Type 2 Solar Panel Strings Up 150V
Protection for Solar Panel Strings Up to 150VDC
The inverters and solar panels must be protected against surge voltages. The PV-Guard-150 is rated to 40kA and 150V, ideal for low-voltage solar off-grid inverters.
The device is compliant with PV standard EN-61643-31. The din rail mounted SPD is widely used in solar combiner boxes to protect the solar panels and inverters from surges in voltage and lightning. The protection method is a high-energy Varistor.
Photovoltaic installations require large surfaces and for that reason, they are exposed to lightning effects and surges. With surge protection devices we avoid failures and maximise the profit and production.
