Deye HVB750V/100A Battery Cluster Control Box

The control point of a matched battery cluster

The Deye HVB750V/100A cluster control box is a component of a supported Deye high-voltage BOS-G storage system. It belongs between the battery cluster and the wider energy system according to the manufacturer architecture. It does not add stored kilowatt-hours by itself: battery modules provide energy capacity, while the matched control arrangement enables the cluster to operate as a coordinated system.

Read amperes and amp-hours correctly

The 100A designation refers to current, not a 100Ah battery capacity. The manufacturer family datasheet lists 100A nominal charge/discharge current and 125A maximum current under the applicable conditions. These figures must be interpreted together with the permitted battery configuration and inverter limits. They are not a guarantee that every connected system can continuously deliver the maximum value.

Match the complete voltage range

The stated operating voltage range is 120–750V DC. The required number and arrangement of battery modules must also satisfy the inverter operating window and the approved BOS-G configuration. A broad voltage range does not establish universal compatibility with other manufacturers or different Deye battery families. Specify the complete system before treating the control box as the correct replacement or new-build component.

Confirm the regional version before supply

The HVB750V/100A family includes regional versions, so the full model suffix matters. Ask Solar Deity to confirm the delivered label, cable set and matching manual against your installation. If replacing an existing unit, provide its nameplate details and the rack configuration rather than selecting solely from a similar-looking enclosure photograph.

Allow for the actual size and weight

The published dimensions are 440 × 570 × 150mm and the listed weight is 15.5kg. This is installed electrical equipment, requiring appropriate support and handling. The IP20 rating means the component must be located in a suitable protected indoor installation. Plan access to connections and service points alongside the space required for the associated battery modules.

Separate component cost from system scope

A control box listing should not be mistaken for a complete storage package. Confirm whether the quotation includes the rack, battery modules, communication leads, power cables and other required components. The system energy capacity comes from the selected battery modules, and usable capacity depends on the commissioned settings and operating conditions. An itemised quote makes this distinction easier to check.

Replacing a control box in an existing rack

Document the installed module type, module count, inverter model, firmware and the full label of the existing controller. A replacement must suit the actual supported configuration, rather than only the nominal current rating. Arrange assessment by the responsible installer before changing components, and retain the commissioning record so the replacement can be checked against the original design.

Frequently asked questions

Does the box store energy? No; the battery modules determine nominal stored energy. Is 100A the same as 100Ah? No; current and charge capacity are different measurements. Can this box control any high-voltage battery? The voltage rating alone does not establish compatibility. Use the supported Deye battery architecture and confirm the regional version.

Prepare an itemised system enquiry

Send Solar Deity the exact battery family, planned module count and inverter model. Include whether this is a replacement or a new rack, and request a list of included cables and mounting accessories. Have the installer review the proposed configuration and the matching manufacturer documents before the equipment is ordered or the rack is altered.

Commissioning and system handover

The completed installation should be commissioned according to the applicable equipment instructions, including the required communication and protection checks. Ask the installer to record the final configuration and explain the operating indicators and normal shutdown procedure. Keep the equipment labels and support documents accessible for future maintenance or a planned system expansion.

Technical reference and ordering support
