Application:
BRPV Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).
Used for surge protection of electrical components in any other DC circuit.
These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection.
It is suitable for surge protection of DC power supply line equipment of solar power generation system.
Installation and maintenance：
Installed in parallel at the interface of LPZ1 zone and subsequent zones: power controller, power converter, etc.
When the surge arrester is installed under the required conditions, it does not require long-term maintenance, but only routine maintenance. If the color of the visible alarm window changes to red (fault) during use, it indicates that the surge protector is damaged and needs to be repaired or replaced.
