China manufacturer pv array combiner boxProduct Description
For large-scale PV grid-connected power generation
system, in order to reduce the connection between the PV module and
the inverter, and to facilitate maintenance to improve
reliability,it generally need to add DC busbar device between the
PV module and the inverter. Our company's PV array lightning
protection combiner box is designed to meet this requirement and
can be designed to a complete PV power generation system solution
with PV inverter products. Using PV combiner box, the user can put
certain number of same specifications PV modules into series PV
module according to input DC voltage range of the inverter, and
then a number of series PV modules access to the PV array lightning
protection box.It's convenient to facilitate the post-inverter
through the output for lightning protection device and circuit
breaker. The PV array lightning protection box has the
following characteristics:(1) meet the requirements of outdoor
installation, protection class IP65, with anti-UV, anti-acid,
anti-alkali, moisture, mildew, rodent control and other
functions;(2) access PV array, each with 15A, 1000Vdc
fuse (replaceable other grades); (3) Equipped with
special high-voltage lightning protection device, lightning
protection function with cathode and anode ;(4) Positive,
negative string into the fuse; (5) Use quadruple PV
dedicated circuit breaker with positive and negative in
series; Part numberdescription1Negative convergence
