Air Cooled Commercial Energy Storage Cabinets 50 KW 115.2 KWh IP54 Level Intelligent

Equipment Overview

The manufacturer describes ten air-cooled battery packs, a 50 kW ESS converter, on/off-grid switching (STS), BMS, EMS, temperature control and fire protection. The LFP battery operates at 768 V nominal. The cabinet measures 1150 × 1100 × 2050 mm (W × D × H) and weighs 1450 kg.

YINTU is an energy storage solution provider. We match project requirements with products from capable manufacturing partners, including YOTAI, and coordinate equipment selection, technical clarification and supply. The equipment described here is YOTAI's Ener Hexon series; YINTU's project scope is agreed in the quotation.

Commercial & Industrial Application Scenarios

Small factories and workshops

Schedule charge and discharge around production shifts and demand peaks. A 50 kW converter can serve a selected portion of the site demand; motors, compressors and welding equipment need starting-current and load-quality checks before sizing.

Retail, offices and commercial premises

Shift energy between selected tariff periods and maintain a reserve for essential circuits such as lighting, communications and access systems. Use the actual demand profile to balance daily energy management against backup readiness.

Warehouses and cold-chain support

Assess storage for selected refrigeration, controls and logistics loads where brief interruptions or demand peaks create operational concerns. Compressor starting currents, required ride-through and temperature-control procedures must be evaluated; do not assume the whole facility can be backed up by one cabinet.

Rooftop solar self-consumption

Connect through the site's AC network with a compatible external PV inverter. Store selected surplus generation for evening activity or later production shifts, with EMS settings designed around export limits and the site's load pattern.

Remote branches and small microgrids

The datasheet specifies both grid-connected and off-grid AC operation. Evaluate essential-load supply at smaller remote facilities, mines or village service buildings with an agreed switching and protection design. Generator coordination, where needed, must be verified separately.

System Features and Project Value

Integrated cabinet

Battery packs, converter, BMS, EMS and STS reduce the number of separately selected storage subsystems while leaving site installation and protection to the project design.

Air-based temperature control

Smart air conditioning and fans manage cabinet temperature. Provide service access and suitable airflow; output derating applies above 45°C.

Expansion planning

The manufacturer describes a 50–300 kW expansion range. Parallel operation, cabinet count and site distribution must follow the supplier-approved architecture.

Monitoring and maintenance

RS485, Ethernet and 4G communication options support project monitoring. Confirm network access, remote service availability and operator permissions in the final scope.

How the System Fits Your Site

This is an AC-coupled solar-storage concept. An external PV inverter supplies the site AC bus, while the cabinet's integrated converter charges or discharges the battery. STS is identified in the manufacturer description, but transfer time is not specified. Backup design must define grid isolation, essential-load circuits, protection and the intended operating sequence.

Documentation

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

Agree the final equipment list, metering, protection, switchgear, transformer (if required), cables, foundations, installation, commissioning and service responsibilities before ordering. PV modules, generators, wind turbines, EV chargers and site works are included only when listed in the quotation. Warranty, lead time, MOQ and price are confirmed for the selected configuration.

Frequently Asked Questions

Does Solution115 include an inverter or PCS?

The manufacturer describes an integrated 50 kW ESS converter together with BMS, EMS and STS. The project quotation should confirm the complete offered configuration and site-side equipment.

Can it connect directly to PV strings?

The supplied datasheet does not specify a direct PV MPPT interface. The illustrated solar application uses an external PV inverter on the AC side.

Does STS mean zero interruption?

No transfer-time value is supplied in this datasheet. Confirm the actual switching performance against the needs of each essential load; equipment requiring uninterrupted supply may need a dedicated UPS.

How is backup duration selected?

The nominal energy-to-power ratio is 115.2 / 50, or about 2.30 hours. This is not usable AC runtime. Confirm the usable SOC window, load variations, losses and temperature before setting a backup target.

Figures are taken from the supplied manufacturer datasheet and are subject to the final order specification. Rated battery energy is not guaranteed usable AC energy. Runtime depends on the usable SOC window, load, temperature, conversion losses and auxiliary consumption. Application images are illustrative concepts, not photographs of completed YINTU projects.
