AC photovoltaic grid-connection distribution box with metering, surge protection, isolation, status indication and optional RS485 monitoring.
The PV AC Distribution Box sits between one or more grid-tied inverter outputs and the facility or utility connection point. It organizes AC input circuits, output isolation, surge protection, energy metering and operating indication in one enclosure so the grid-connection boundary is clear and maintainable.
Configurations can include a lead-sealable meter position, islanding and over/undervoltage protection, an isolating switch with visible break, and optional voltage-check automatic reclosing. RS485 monitoring is available when the project requires the box to report into an energy or facility platform.
Selection depends on inverter quantity, AC voltage, maximum current, grid-connection method and utility requirements. Provide each inverter output, cable size, fault level, metering arrangement and protection settings. Islanding and automatic-reclosing functions must follow the approved project protection philosophy rather than a generic default.
Huijue Group can manufacture a PV AC distribution box from an approved single-line diagram and review private-label/OEM markings, meter windows and sample-based enclosure formats. Engineering confirms grid-interface feasibility, meter-window and panel tooling, components, routine tests, order volume and equipment/documentation delivery scope.
| Configuration | Project-specific; confirm requirements before quotation. |
Specify indoor or outdoor location, ambient range, moisture/corrosion exposure and mounting method. Enclosure protection, SPD coordination, earthing and anti-islanding arrangements must be selected for the actual installation.
Buyer Questions
Answers specific to PV AC Distribution Box selection, configuration and purchasing.
Yes, multiple AC input circuits are configurable. Their breakers, busbar and enclosure must be sized from the individual and simultaneous inverter currents.
A lead-sealable meter arrangement can be provided. Confirm the utility-approved meter model, current-transformer requirement and ownership boundary.
Yes, an approved drawing can form the basis for OEM production after protection logic, components, labels, testing and project quantity are agreed.
Use the deployment context to narrow the configuration before comparing dimensions, capacities and options.
Coordinate DC power, distribution, batteries and monitoring around communications loads.
Use integrated or wall-mounted systems where equipment space is limited.
Match generation, storage and power conversion to load and autonomy requirements.
Combine grid, solar, battery or generator inputs around a defined operating strategy.
Before quotation: confirm capacity, interfaces, installation environment, power conditions, quantity and required options.
