BWX Grid Connected Box Single Phase/Three Phase Grid Connection
IP45/ IP55/IP65
Summarize
The product is mainly used in household photovoltaic distributed
grid-connected power generation system, small industrial and
commercial photovoltaic power generation system, series connected
between the grid-connected inverter and the power grid, the product
has anti-island protection check voltage closing voltage loss trip
grid low voltage, power grid overvoltage, input lightning
protection, system overcurrent, power grid isolation and a series
of protection.Accurate power metering,transmission and intelligent
operation control is an essential part of the household
grid-connected power generation system, and the products have
passed the industry standard CCC certification and CE
certification.
Main feature
Reserve the installation location of metering meters and
collectors;
Metering meter can be window, lead seal (anti-theft); The
integrated design concept of the product, the distribution part and
the metering part are completely isolated, reducing electromagnetic
interference; A variety of self-compound overvoltage and
undervoltage protectors,photovoltaic special recloser circuit
breakers are optional to meet the needs of different regions and
acceptance standards; The lid needs a professional key to open, to
achieve professional management;
Spray box and stainless steel box optional; Outdoor
installation,safer use;
Support special requirements and function customization.
