OEM All-in-One ESS Manufacturing Process
A structured, transparent process from initial spec to final delivery — designed for OEM partners who demand precision.
1. OEM Specification & BOM Review
We begin with a thorough review of your technical requirements — capacity (kWh), voltage range, inverter compatibility, enclosure rating, and certification targets — before finalizing the BOM.
2. Grade-A Cell Procurement & Incoming QC
Only Grade-A LiFePO4 or NMC cells from CATL, EVE, or BYD are used. Every batch undergoes incoming capacity, IR, and self-discharge testing before entering production.
3. Module Assembly & BMS Integration
Cells are assembled into modules in our dust-controlled workshop. The BMS is calibrated and integrated, with parameters configured to match your inverter protocol and safety thresholds.
4. Enclosure Build & IP Rating
The complete system is assembled into your specified enclosure — wall-mounted, floor-standing, or rack format — with IP55 or IP65 sealing, cable management, and OEM branding applied.
5. Full System Charge-Discharge & Safety Test
Every unit undergoes full charge-discharge cycling, overcharge and over-discharge protection testing, short-circuit simulation, and thermal runaway validation before shipment clearance.
6. Certification, Packaging & Export Logistics
We coordinate UN 38.3 transport documentation, CE/UL declaration of conformity, and export packaging to UN standards — with full support for sea freight, air freight, and DDP delivery.
Frequently asked questions about ESS solutions
What is an energy storage system (ESS)?
An energy storage system (ESS) uses batteries to store electricity for later use, enabling backup power and greater use of renewables.
How does a home battery backup system work?
Home battery backup systems charge from solar panels or the grid and automatically power selected home circuits when the grid goes down.
What are the benefits of a home battery backup (residential energy storage)?
Residential battery storage lets you store excess solar power for later use, reducing grid reliance and electricity bills, while providing reliable backup power during outages.
How much does a home battery backup system cost?
In the U.S., a basic home battery backup (essential-circuits) starts around $3,000–$5,000, while larger whole-home systems (20–40 kWh) typically run $8,000–$15,000 or more.
How long will a home battery backup power my house?
A typical 10–15 kWh home battery backup can supply essential loads (~1–2 kW) for roughly 8–24 hours. Adding more batteries (higher capacity) can extend runtime into multi-day outages.
How much battery capacity do I need for my home?
A typical U.S. home uses ~20–30 kWh/day. To back up only essentials (lights, fridge, Wi-Fi) you’d need ~10–15 kWh; for full-home backup (HVAC, ovens, etc.), plan ~20–40 kWh of storage.
Are home battery storage systems safe and reliable?
Modern home battery storage (Li-ion) systems are designed with multiple safety features and last ~10–15 years. They typically retain 70–90% capacity even after 6,000–10,000 cycles.
Do I need solar panels to use a home battery?
No – a home battery backup can be installed without solar, charging from the grid. (That said, pairing it with solar maximizes renewable use and savings.)
What is a portable energy storage system (portable power station)?
A portable energy storage system (portable power station) is a transportable battery backup that provides clean, quiet off-grid power (for camping, RVs, events, etc.), serving as a modern alternative to noisy fuel generators.
