WCED Solar PV Combiner Boxes — 1000V DC

WCED solar PV combiner boxes bring DC isolation and DC surge protection together in an IP65 enclosure between the array and inverter. Choose a one-string or two-string configuration, in metal or plastic.

Choose by string layout and enclosure

• WMPV-1S1: one input / one output, metal IP65.
• WPPV-1S1: one input / one output, plastic IP65.
• WMPV-2S2: two inputs / two outputs, metal IP65.
• WPPV-2S2: two inputs / two outputs, plastic IP65.

The two-string versions provide two string paths. Do not assume they parallel strings; follow the exact wiring diagram and inverter MPPT arrangement.

What the features do

• DC isolation: provides a means to disconnect the downstream DC circuit in accordance with the device instructions. PV conductors upstream can remain live in daylight.
• DC surge protection: limits transient overvoltage on the PV side. It does not replace the separate AC-side protection design.
• 1000V DC range: check maximum cold-weather array voltage and string current against the chosen model’s datasheet.
• IP65 enclosure: dust-tight and resistant to water jets when correctly installed with suitable entries and seals. Check the installation environment and mounting instructions.

Before ordering

Confirm the string input/output arrangement, maximum voltage and current, isolation rating, SPD specification and enclosure dimensions against the exact model. Do not assume string fuses are supplied: confirm the assembly contents and any additional overcurrent protection required for your array.

WCED manufacturer range and model datasheets

Do you also need AC-side protection?

The WCED solar PV consumer unit is a separate AC assembly with a 20A bi-directional RCBO, 32A isolator and kWh meter. It does not replace the DC combiner.
