Buy 5.6 MWh containerized battery storage
A defined battery-container offer for utility-scale energy storage developers, solar-plus-storage projects, EPCs, IPPs and commercial or industrial project teams. Compare the DC battery block against your required usable MWh, DC power, PCS configuration and energization schedule.
The supplied offer describes production-ready equipment held in a U.S. warehouse. Current allocation, individual unit condition, manufacturing dates, inspection and release timing are confirmed with your quotation. The 840 MWh figure is 150 × 5.6 MWh of nominal DC energy, not an installed or commissioned power plant.
LFP battery container specifications
Liquid cooling, a 1,040–1,500 V DC operating range and a 20-foot high-cube container format are identified in the supplied package. Review the final OEM data sheet and allocated unit records before technical acceptance.

Confirm nominal DC voltage and PCS input limits against the final OEM data sheet for the units allocated to your order.
DC battery blocks with PCS skids available separately
The offered BESS units are DC battery blocks. A PCS skid combining DC-to-AC conversion and a transformer can be quoted separately. PCS skids are not in stock; the supplied offer indicates a typical lead time of about 100 days, subject to specification and written quotation.
Confirm the battery/PCS electrical interface, inverter power, AC voltage, frequency, controls, protection, grounding, auxiliary supply and transformer requirements for your project. Civil works, installation, interconnection and commissioning are not represented as part of the DC-block offer unless included in the written contract.
Battery storage for solar, utility and industrial projects
Screen these containerized LFP battery blocks for solar-plus-storage, renewable energy storage, utility battery storage and commercial or industrial energy-storage requirements. Peak shaving, energy shifting, capacity and ancillary-service applications depend on the selected PCS, controls, duty cycle and project approvals.
For a four-hour battery storage requirement, send both the required AC MW and usable MWh. The supplied ≤0.25P specification does not by itself establish guaranteed AC output, usable energy, round-trip efficiency or duration at your site. J&J can coordinate battery, PCS and transformer information for engineering review.
Warranty, storage records and technical documentation
The supplied offer states a three-year standard warranty beginning at purchase/payment, with capacity-retention and degradation terms governed by the final OEM warranty. Request the written warranty and the records matching the allocated units before purchase.
The supplied material references UL 1973, UL 9540, UL 9540A, IEC standards and other conformity or code requirements. Request the actual certificates, listings, test reports, applicable model numbers and tested system configuration. References in an offer do not establish certification or approval of a complete installed project.
Request the current state of charge, storage dates, preservation requirements, condition inspection, unit-level manufacturing records, capacity test basis and matching degradation curves. Storage and operating assumptions must agree with the final warranty.

Request BESS pricing and warehouse release timing
Call Tommy Marco at 346-276-9540 or email tommy@jjtransformers.com. Include your company name, required quantity, ship-to location, needed-on-site date and whether you need a separate PCS skid. Pricing is quoted ex-works the U.S. warehouse; current availability and release are confirmed in writing.
Add your target MW and usable MWh, grid or behind-the-meter duty, AC voltage and frequency, and any project certification requirements. Ask J&J for the unit schedule, technical package, inspection arrangements, warranty, loading scope and freight quotation. Equipment remains subject to prior sale.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
How many BESS units are offered?
150 LFP battery containers are offered at 5.6 MWh nominal energy each, or 840 MWh total nominal energy across the lot. Current allocation and available quantity require written confirmation from J&J.
Is the 5.6 MWh BESS a complete AC energy storage system?
The offered supply is a DC battery block. PCS inverter-transformer skids are sold separately, are not in stock, and have a supplier-indicated typical lead time of about 100 days, subject to project requirements and quotation.
Are the battery containers liquid-cooled LFP units?
Yes. The supplied offer identifies LFP chemistry, liquid cooling, IP55 protection and a 20-foot high-cube container format. Confirm the final OEM specification and allocated unit records with the quotation.
What is the price of the BESS containers?
Contact Tommy Marco at 346-276-9540 or tommy@jjtransformers.com for a current quotation. Send your company name, quantity, ship-to location and required date. The offer is ex-works a U.S. warehouse; freight, PCS and any additional scope are quoted separately.
Can these units be reviewed for a four-hour battery storage project?
Send your required AC MW, usable MWh and duty cycle for review. The supplied ≤0.25P specification is a DC-block parameter; final discharge duration, usable energy, AC output and efficiency depend on the confirmed battery configuration, PCS and operating conditions.
When does the three-year BESS warranty start?
The supplied offer states that the standard three-year warranty begins at purchase/payment. Coverage, capacity-retention curves, exclusions and warranty provider must be confirmed in the final written OEM terms for the allocated units.
