Battery ESS split cabinet systems place the battery in separate outdoor cabinets alongside a dedicated PCS cabinet, so a C&I project can size power and energy from 300kW / 723kWh up to 1.26MW / 2.508MWh. Start with the site load profile, required duration, grid interface, and installation conditions—not a headline kWh figure alone.
Each system combines LiFePO4 battery cabinets with a separate PCS cabinet. The HC-UPSSP series uses three, four or five air-cooled battery cabinets; the HC-UPSA2508L04 moves to an 800V platform with liquid-cooled battery cabinets. Final power, duration, grid connection, and operating mode are confirmed against the site brief.
Power in kW defines how much of a peak the system can cover; usable energy in kWh defines how long it can hold that output. Use interval data to test both values before comparing cabinet models.
Ask for the applicable model datasheet, certificate and test scope, fire-system information, protection drawings, and installation documentation. Requirements differ by project, country, and authority having jurisdiction.
Peak shaving, tariff arbitrage, PV self-consumption, and backup reserve can compete for the same stored energy. Define the priority, reserve level, dispatch window, and control assumptions in the project brief.
Confirm transport route, foundation or pad, clearance, service access, cable routing, drainage, ambient conditions, and expansion space. A cabinet is the right form factor only when the site layout supports it.
Cooling selection should follow the intended C-rate, cycling frequency, ambient conditions, maintenance approach, and model documentation. Do not use a cooling label as a shortcut for site suitability.
The engineering review should identify the PCS, EMS, transformer, protection, communications, commissioning, and after-sales responsibilities. This prevents a product quote from being mistaken for a complete project scope.
Compare the starting model data here, then review the relevant product page and project inputs. The table does not replace a load, site, interconnection, or documentation review.

A cabinet system is not selected from capacity alone. A useful first brief records the measured peak and duration, tariff or value stack, critical-load requirement, PV and grid interface, physical constraints, and the documents the project must satisfy.
Use interval load data to identify the peak to be clipped, its recurring duration, and the demand or time-of-use charge that creates value. The kW target and kWh duration must be tested together; an undersized duration can leave the monthly peak unchanged.
The HC-UPSSP series includes MPPT inputs for a PV array (up to 600–720kW depending on model). Map the array, export limit, and control objective first. To add storage to an existing PV inverter instead, review the AC-coupled battery energy storage cabinet.
Start with the loads that must remain powered, required autonomy, transfer arrangement, and operating reserve. Backup capability is a system-design question involving the site electrical architecture, not a promise inferred from battery capacity alone.
Use the C&I solution page to compare a cabinet with a larger container layout, identify the load and tariff inputs, and prepare a first engineering review.

Read the sizing guideA split cabinet system separates the battery cabinets from the power conversion (PCS) cabinet. Each Hua Power model in this range pairs LiFePO4 battery cabinets with one PCS cabinet, so capacity is set by the number and type of battery cabinets.
HC-UPSSP723 (300kW / 723.45kWh), HC-UPSSP964 (400kW / 964.60kWh), HC-UPSSP1205 (500kW / 1,205.76kWh) and HC-UPSA2508L04 (1.26MW / 2.508MWh). Review each product page for full parameters.
The HC-UPSSP models use air-cooled battery cabinets on a 400V AC connection with MPPT inputs for PV. The HC-UPSA2508L04 uses liquid-cooled battery cabinets, an air-cooled PCS cabinet, and an 800V AC connection.
The HC-UPSSP models list MPPT inputs for PV in their specifications. Array size, export limits, and the control strategy need a project-specific review before a configuration is confirmed.

Share interval load data or utility bills, the peak or backup objective, tariff structure, PV and grid interface, site layout, and required documents. Our engineering team can return a first-pass cabinet configuration and identify the project questions that still need review.
