The PV combiner box
Eaton has introduced a new line of monitored combiner boxes
designed for use with all module and inverter combinations.
Combiner box features include:
•
Designed and tested to the requirements of IEC 61439-1 and 2.
•
Compact, low-cost and highly flexible design.
•
Easy to connect input and output cabling via MC4 connectors or
IP65 rated glands.
•
Available in IP65 rated fibre-glass reinforced polyester (GRP),
IP65 powder-coated galvanised steel enclosures and IP65 rated
stainless steel in a range of sizes.
•
Internals are “touch safe” to IP20.
•
Design options include integrated load disconnects, monitoring
solutions, surge protection devices, self-powered or externally
powered solutions and wireless communication.
•
External wired modbus connection port.
Product description
For specific details regarding your combiner box design, please
see the documentation included in your order. This should provide
a detailed assembly layout and wiring diagram.
The product description is demonstrated through the Part Number
Breakdown and Rating Plate. Please ensure that careful attention
is paid to the information that is represented on the rating plate to
ensure that you are aware of the specifications of your individual
combiner box design.
Standard configurable products
Part numbers for projects outside the standard configurable prod-
ucts will be determined by an individual project part number.
