52 KWh / 25 KW Hybrid ESS Energy Storage Cabinets IP54 For Commercial Industrial

Equipment Overview

The cabinet integrates 52 kWh rated battery energy, 25 kW rated AC power, up to 38 kW PV input, battery air conditioning, intelligent PCS cooling and integrated fire protection. External PV modules, generator equipment, distribution, protection and installation works are defined separately in the project scope.

YINTU is an energy storage solution provider. We combine project requirements with products from capable manufacturing partners, coordinating equipment selection, system interfaces and technical documentation for the customer and local installation team.

Small Business and Large Estate Applications

Small shops, offices and bakeries

Store available daytime solar energy for later operating hours and selected essential loads. Review refrigeration, lighting, IT and production schedules separately; heating equipment and motor starting loads must fit the 25 kW power envelope.

Large homes with a three-phase supply

Combine rooftop PV with a 52 kWh battery reserve for selected household circuits. Prioritize lighting, communications, refrigeration and agreed comfort loads instead of assuming every appliance can run simultaneously.

Small workshops and service businesses

Plan charging around production hours and tariff periods where the local tariff supports this strategy. Measured load data determines whether the cabinet can reduce demand peaks; savings depend on the site and operating controls.

Rural properties and utility outbuildings

Support a planned energy system for a residence and selected farm or estate services. Irrigation pumps and other motors require assessment of starting current, phase balance and operating sequence.

Sites with weak-grid or backup needs

Use the generator interface as part of an engineered solar-storage-diesel scheme. Reserve battery energy for priority circuits and agree generator ratings, start/stop logic and isolation with the equipment supplier.

System Features and Project Value

Solar and storage in one cabinet

Two MPPT channels support a specified maximum PV input of 38 kW. PV string design must respect the 850 V DC maximum voltage, 200–800 V DC MPPT range and 30 A + 30 A maximum input current; PV nameplate power is not battery discharge power.

Capacity selected around the operating plan

The 52 kWh rating describes nominal battery energy. Usable AC energy and runtime depend on discharge limits, conversion losses, auxiliary consumption, temperature and the reserve policy. Load measurements are required for a meaningful backup estimate.

Three-phase grid and off-grid operation

The specified connection is L1/L2/L3/N/PE at 400/230 V AC. Grid-connected and off-grid rated powers are the same for each configuration. Confirm phase balance, starting loads, local connection rules and protection coordination.

Generator coordination and transfer

A diesel generator port is specified, with a grid/off-grid switching time below 10 ms. Transfer performance depends on configuration and load requirements; this is not an unconditional no-break guarantee for every appliance or IT load. Generator ratings and control details require confirmation.

Cabinet environment and monitoring

IP54 cabinet protection, battery air conditioning, intelligent PCS cooling and integrated fire protection support the equipment design. RS485/WiFi communication is specified. Installation location, drainage, foundation, clearance and access must follow the approved project documents.

How the System Fits Your Site

PV connects to the integrated MPPT inputs. The 52 kWh battery and PCS manage energy within the cabinet, while the AC connection serves selected three-phase business or estate loads. Grid and diesel generator interfaces must use the approved isolation, protection and control arrangement. The diagram is a functional overview, not installation wiring or permission to parallel sources. Export, zero-export and generator operating modes must be confirmed for the project.

From Site Requirements to a Storage Solution

1. Define the operating objective

Identify whether the priority is peak management, solar self-consumption, backup or microgrid operation. Use the actual load profile and generation resources to set the power, energy and operating reserve.

2. Match equipment and interfaces

YINTU coordinates equipment selection and technical clarification with the manufacturing partner, including voltage, controls, environment, expansion and optional functions.

3. Confirm delivery and service scope

Confirm the cabinet configuration, PV string design, grid requirements, generator controls, protection, earthing, installation clearances and commissioning responsibilities before ordering. YINTU coordinates the technical scope with the manufacturing partner; local qualified professionals complete the approved installation. Warranty, certification documents, lead time and after-sales arrangements are confirmed in the project quotation.

Frequently Asked Questions

Is this suitable for a large home or estate?

It can be considered for a property with a suitable three-phase electrical system and a professionally designed installation. A site survey must confirm voltage, phase balance, peak demand, motor starting and backup circuits. It is not a plug-in appliance for an ordinary single-phase household.

How long will the battery power the site?

The nominal 52 kWh battery rating does not define a fixed runtime. Share the critical-load profile and required reserve so the usable energy, losses and operating limits can be assessed. Entire-site backup must not be assumed.

Can existing PV and a diesel generator be used?

Possibly, after checking the PV electrical design and existing inverter architecture, as well as generator interface and control compatibility. The built-in PV input and generator port do not remove the need for a site-specific integration design.

Can more cabinets be connected?

The datasheet lists a maximum of three parallel units in the off-grid section. Confirm the approved configuration, controls and protection with the supplier; parallel capability in every operating mode is not implied.

Does YINTU manufacture this cabinet?

YINTU provides energy storage solutions using products from manufacturing partners. We help clarify requirements, select the appropriate equipment and coordinate technical and delivery arrangements. Project certification, warranty and service scope are confirmed before ordering.

Specifications are transcribed from the supplied YINTU datasheet, version 1.0 (2026.10). Dimensions follow the source order. Images are illustrative and configuration may vary. Final equipment, interfaces and operating limits are subject to the confirmed technical agreement. Nominal battery energy is not usable AC energy or a guaranteed backup duration.
