265kWh Energy Storage Battery

HSS Energy manufactures the 265kWh Energy Storage Battery for commercial quotations, project sourcing and OEM or ODM orders. The system is built from eleven 76.8V 314Ah LiFePO4 modules connected in series and managed by one battery control unit. Its catalog values are 844.8V nominal voltage, a 765.6-950.4V operating range and 265.27kWh nominal energy. An integrated cabinet with air-conditioning and fan cooling is used for commercial solar storage, peak management and selected-load backup. Before pricing is issued, HSS Energy reviews the PCS or inverter model, DC voltage window, communication protocol, target power, site environment and required compliance documents so the quoted configuration reflects the real project rather than a generic capacity label.

HSS Energy supplies the 265kWh Energy Storage Battery to system integrators, EPC contractors, distributors and industrial customers who need a matched high-voltage battery cabinet rather than a loose group of modules. The eleven-module series string, battery control unit, DC protection, cooling, communication and PCS interface are checked as a complete system. customers may submit a single-line diagram, load profile and equipment list for configuration review, customized labeling, delivery planning and a formal quotation.

1. Eleven 76.8V Modules Form the High-Voltage String

The High Voltage Stackable Lithium Battery architecture uses eleven 76.8V 314Ah modules in series, with one BCU supervising the complete string. This gives 844.8V nominal voltage and a catalog operating range of 765.6-950.4V. For every 265kWh Energy Storage Battery project, the series addresses, pre-charge sequence, protection thresholds and cable interfaces are recorded in the approved technical file. The stackable format supports organized service access, but it does not mean modules may be added or removed without rechecking the PCS voltage window and BMS settings.

2. Commercial Solar and Load-Management Applications

The HV Solar Energy Storage Battery is intended for commercial photovoltaic self-consumption, time-of-use shifting, peak shaving and backup of selected loads. It can also be considered for microgrid and industrial energy-management projects after the site control strategy is defined. A 265kwh solar battery should be sized from actual load and generation data: stored energy alone does not determine the PCS power, backup duration or financial return. HSS Energy therefore asks for load curves, operating hours and the required backup boundary before confirming a proposal.

3. Inverter Matching, Including a 125kW Solis Example

This High Voltage Commercial Storage Battery can be evaluated with Deye, Solis, Afore, Growatt, FOX ESS and Megarevo equipment. The datasheet also presents these brands as compatible families, but actual connection depends on the exact PCS or inverter model and protocol version. For a 125kW Solis inverter, HSS Energy checks the DC battery range against 765.6-950.4V, confirms the permissible battery current, reviews CAN or RS485 communication and completes a protocol test before production. Brand-level compatibility is not treated as approval for every model.

4. Cabinet Protection and Thermal Design

The commercial and industrial energy storage system uses an integrated cabinet with air-conditioning and fan cooling. The supplied datasheet specifies IP54, while project deliveries may use an IP55 outer enclosure when that requirement is written into the confirmed order. This distinction matters because door seals, cable entries, ventilation paths and external cooling equipment all affect the final protection level. Site placement, service clearance, ambient temperature, dust and rain exposure should be reviewed before the cabinet drawing is released.

5. BMS Communication and Wi-Fi Monitoring

The BCU communicates through CAN and RS485 and collects operating information from the module BMS units. The datasheet also shows a built-in Wi-Fi monitoring device developed with the BMS supplier UDAN, with Chinese and English display options. Monitoring availability, app access, data fields and network method are confirmed for the ordered configuration. A physical CAN or RS485 port does not by itself prove compatibility with the selected PCS, so communication files and test conditions remain part of the pre-production review.

6. Production, OEM/ODM and Quality Control

A 265kwh Ess Battery storage system is released for production only after the system drawing, module quantity, BCU setup, cooling arrangement, protocol, labels and delivery documents have been confirmed. HSS Energy supports cabinet, marking and project-document customization for qualified OEM and ODM orders. The company was established in 2023, and its partners have more than ten years of lithium-battery industry experience. Multiple production bases in China cover approximately 12,000m², with automated assembly, laser welding, aging tests and outgoing inspection used across battery projects. Catalog claims such as cycle life and certification are kept tied to their stated configuration and conditions.

7. Packaging, Shipment and After-Sales Handover

The datasheet gives an approximate system weight of 2,312kg for the eleven-module cabinet, so unloading equipment, floor loading, access route and final placement must be checked before dispatch. Packaging and labeling are prepared for the agreed route, destination and transport-document list. HSS Energy provides the manual and project technical files that match the order. Wiring, commissioning, alarms and maintenance procedures are kept in the operating manual rather than expanded on the product page. After-sales communication starts from the serial number, site information and a clear description of the operating condition.

FAQ

1. How is the 265kWh capacity calculated?

Each module is rated at 76.8V 314Ah, or approximately 24.12kWh. Eleven modules in series retain 314Ah capacity and produce 844.8V nominal voltage, giving 265.27kWh nominal energy.

2. Is the cabinet IP54 or IP55?

The supplied datasheet lists IP54. An IP55 project enclosure may be provided when the cabinet design and protection requirement are confirmed in the quotation and technical specification.

3. Can the system work with a 125kW Solis inverter?

It can be evaluated for that application, but the exact Solis model must be supplied. DC voltage range, battery current, communication protocol and control logic are checked before compatibility is confirmed.

4. Are Deye, Growatt, FOX ESS and Megarevo also supported?

These brands are listed or identified as potential compatible families. Final approval remains model- and protocol-specific.

5. Is Wi-Fi monitoring standard?

Wi-Fi monitoring is shown in the supplied datasheet. Confirm the monitoring hardware, app access and network method in the order configuration.

6. What should be provided for a quotation?

Please send the target PCS power, exact inverter model, load profile, solar capacity, site environment, required IP rating, quantity, destination, compliance-document needs and delivery schedule.
