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 feature
●The cabinet is made of hot-dip galvanized steel plate, the
structure of the cabinet is safe and reliable, and has enough
mechanical strength to ensure that the components are not shaken or
deformed after installation and operation.
●Protection class IP65, with waterproof, ash, rust, salt spray, to
meet the requirements of outdoor installation; Up to 24
photovoltaic arrays can be accessed simultaneously;
●The positive and negative poles of each battery series are
equipped with photovoltaic fuses for protection, and the fuse base
and fuse are used together to reduce the owner's later maintenance
costs and effectively protect the personal safety of maintenance
personnel;
●The DC output bus is equipped with photovoltaic lightning
arrester. It has good surge protection function between positive
electrode and ground, negative electrode and negative electrode
●The bus box is equipped with a modular intelligent detection unit
to detect the current, output voltage, box temperature, lightning
arrester status,circuit breaker status of each series of
components;
●Intelligent detection unit with digital display function, can
display current, voltage, power, temperature, equipment address,
equipment number and other information on the device body; The
power consumption of the modular bus box intelligent detection unit
is less than 4W, and the measurement accuracy is 0.5%.
