HLX-DC Solar Combiner Box IP65 Wall-mounted 2P 3P 4P Over-voltage Protection

Summarize

The photovoltaic junction box is used in the photovoltaic power generation system to reduce the connection line between the photovoltaic module and the inverter. Through the protection of photovoltaic special fuses.circuit breakers and lightning protectors, the reliability is improved, and the maintenance of the system is convenient. Users can according to the inverter input DC voltage range, a certain number of specifications of the same photovoltaic modules in series to form a photovoltaic module series, and then a number of series connected to the phatovoltaic array lightning busbar, through the lightning arrester and circuit breaker protection output, convenient access to the post-inverter.

Main technical parameters

Main feature
