Can the EMS and monitoring software be white-labeled?

White-labeling of the EMS interface and monitoring screens can be included. What can be rebranded, and how control strategies are configured for your application, is confirmed in the quotation.

Which certifications are available for your BESS products?

Entogo certifies its storage systems to your market’s requirements on request — for example UL 9540 and UL 9540A with CSA in North America, or IEC 62619 / IEC 62933 and CE marking for export markets. The certification, test reports, timing and scope for your system are confirmed in the quotation.

What capacities and configurations can you build?

Catalogue platforms range from 100 kW / 215–232 kWh C&I cabinets and 200–225 kWh compact systems to 2570 kWh containers and MW-level grid-connected / off-grid systems. Cabinets and containers can be paralleled, and the configuration is sized to your project.

Can storage be combined with PV and EV charging?

Yes. DC-coupled systems integrate PV through MPPT, and the storage-and-charging systems add EV charging on existing transformer capacity — useful where grid-connection capacity is the constraint.

What warranty applies to an OEM storage system?

A minimum 36-month manufacturer warranty, issued by Entogo Inc. as the contracting party; the exact term, coverage and start point are confirmed per contract. After-sales requests are answered within one business day.

BESS OEM

BESS OEM manufacturer for commercial, industrial and utility storage

All-in-one C&I cabinets, containerized battery energy storage and DC-coupled PV-storage systems — customized to your project or supplied under your brand, with the EMS and documentation to match.

What we build

Battery energy storage systems available OEM

Built on the catalogue platforms below and configured to your project — capacities shown are catalogue configurations.

Liquid-cooled C&I cabinets

All-in-one 100 kW / 215 kWh and 100 kW / 232 kWh cabinets integrating battery cluster, BMS, EMS, PCS, liquid cooling and fire protection.

Air-cooled C&I cabinets

All-in-one 100 kW / 215 kWh cabinets with intelligent air cooling for factories, commercial complexes and other C&I sites.

Compact storage systems

200 / 225 kWh systems with three-level BMS, parallel battery clusters and a unified DC interface for PV integration.

Containerized BESS

2570 kWh pre-installed containers with air-conditioning thermal control, PV DC coupling and pack-level plus whole-container perfluorohexanone fire protection.

Storage-and-charging systems

DC-coupled storage stacks with split charging terminals that add storage and EV charging on existing transformer capacity at time-of-use sites.

Grid-forming and MW-scale systems

DC-coupled grid-forming / off-grid PV-storage-diesel hybrids and MW-level grid-connected and off-grid systems with built-in STS and 1+1 parallel operation.

What can be customized

Configured to your project, branded as your system

Typical customization areas for OEM and private-label BESS — the exact scope is confirmed in the quotation.

Capacity and power

Energy and power rating, number of cabinets or containers and parallel arrangement sized to your use case — peak shaving, backup, PV self-consumption or time-of-use arbitrage.

System integration

AC- or DC-coupled architecture, PV and EV-charging integration, grid-connected or off-grid operation, and communication to your site controller or SCADA.

Enclosure, cooling and fire protection

Liquid or air cooling, enclosure finish, footprint and fire-protection scheme matched to your site conditions — confirmed in the quotation.

EMS and software white-label

Your brand on the EMS interface and monitoring screens, with control strategies set to your application — white-labeling scope confirmed in the quotation.

Private label

Your brand on the enclosure, nameplate and documentation. Minimum order quantity, branding and packaging are confirmed per project in the quotation.

Documentation and labeling

Manuals, safety labels, single-line and layout drawings in your format and language — scope confirmed in the quotation.

Standards & certification

Certified to your market’s requirements on request

Entogo certifies storage systems to the requirements of your market, application and authority having jurisdiction — UL 9540 / 9540A, CSA, IEC 62619 / 62933 or CE — with timing and scope confirmed in the quotation.

North America

UL 9540 system certification, UL 9540A fire-test reports and CSA certification available on request for permitting; orders that need new cULus/CSA certification ship within 36 weeks.

IEC and CE for export

IEC 62619 (battery) and IEC 62933 (system) certification, CE marking and the supporting test reports on request for export markets — timing and scope confirmed in the quotation.

Management systems

Built under ISO 9001, ISO 14001, ISO 45001 and IATF 16949 management systems in Entogo’s own factory.

Quality & delivery

Integrated, tested and documented in our own factory

Lead time

The same tiers as catalogue products — about 12 weeks for IEC/CE builds, 16–24 weeks for North-American-spec builds, within 36 weeks with new cULus/CSA certification — confirmed in the quotation.

Factory testing

Systems are integrated and tested before shipment, with factory acceptance test documentation, quality inspection reports and serial-number records.

Witnessed inspection

Third-party inspection or a witnessed factory acceptance test can be arranged for eligible projects.

Warranty and service

A minimum 36-month manufacturer warranty issued by Entogo Inc., with after-sales requests answered within one business day.

Confidentiality and origin

Your specifications and branding are covered by a non-disclosure agreement. China is stated as the country of origin up front for duty and origin planning.

A highly integrated, MW-scale grid-connected and off-grid energy system with PV DC access and MPPT (a DC-coupled PV-ESS microgrid), integrated BMS/PCS/EMS control, a built-in STS with sub-20 ms source switching and 1+1 parallel operation.
