Our MCB breaking capacity is up to 10-15KA , the DC
voltage for MCB MCCB SPD is up to 1500V.
The HONI PV AC Grid-Tied Box is a compact outdoor cabinet for the AC side of photovoltaic grid-connected systems. It integrates 4-pole protection, isolation, AC surge protection, earthing and reserved metering / CT positions in a two-compartment IP65 steel enclosure. The configuration can be adapted to the approved project BOM for different solar installations.
Feature | explanation |
Integrated AC protection | A coordinated enclosure for protective circuit breakers, isolation, AC SPD, earthing and metering interfaces. |
IP65 outdoor construction | 1.2 mm cold-rolled steel enclosure with RAL 7035 outdoor powder coating and independent lockable doors. |
Two-compartment layout | Separates the metering / terminal area from the main protective switching area for easier inspection and field service. |
4-pole architecture | Typical configuration uses four-pole switching suitable for three-phase + neutral AC grid connection. |
Surge protection branch | Typical 4P AC SPD requirement: In 40 kA and Imax 80 kA, subject to final approved project design. |
Metering-ready design | Reserved positions for metering / current-transformer arrangements allow project-specific monitoring or utility interface integration. |
Project engineering | Final breaker ratings, SPD selection, metering, CT arrangement, cable access and labels are confirmed against the project BOM before production. |

Typical applications include the AC output side of commercial rooftop PV systems, small solar plants, inverter-to-grid connection points, project-specific AC protection cabinets, and installations requiring an integrated metering / CT interface. Final electrical ratings and protection coordination must be selected for the actual inverter output, grid conditions and project requirements.

Our engineers will confirm the breaker rating, SPD, metering / CT arrangement, enclosure layout and BOM before quotation.
It is an AC-side protection and grid-connection cabinet installed between the photovoltaic inverter output and the utility / project AC distribution point. The configuration can integrate switching, surge protection, isolation, earthing and metering interfaces.
The configuration shown is a 4-pole AC arrangement with a nameplate rated voltage of AC 400 V and rated current of 63 A. Final selection must match the inverter output and project design.
The enclosure is specified as IP65 and is designed for outdoor wall-mounted installation.
The typical drawing specifies a 4-pole AC SPD branch with In 40 kA and Imax 80 kA. The final SPD type and parameters should be confirmed for the project.
The typical BOM includes a 4-pole C50A automatic reclosing circuit breaker. The protection and reclosing logic can be finalized according to the approved project configuration.
Yes. The design includes a reserved metering / CT area. The supplied project documentation shows positions for two meters and seven terminal / junction boxes.
Yes, the final breaker, SPD, metering and CT selections are confirmed against the approved project BOM before production.
The nominal drawing dimension is 550 × 850 × 220 mm including the door.
The enclosure is specified as 1.2 mm cold-rolled steel with RAL 7035 outdoor powder coating.
Please send the inverter AC output voltage, maximum current or inverter power, grid system, required quantity, SPD requirement, metering / CT requirement and, if available, the single-line diagram.
