20kWh All-in-One Home ESS | LFP Battery + Hybrid Inverter Complete System
Specifications
How we verify OE matching
Every EV battery SKU is cross-checked against the manufacturer's original part number before shipping. Three-step verification process:
-
1
OE number cross-reference. Catalog part number matched against the OEM's published reference for the target vehicle (Toyota, Honda, BYD, Tesla, etc.). Identical OE = guaranteed fitment.
-
2
Cell-level grading. Each pack is assembled from capacity-matched and internal-resistance-matched cells. Voltage, IR, and self-discharge values recorded against the OE spec.
-
3
Diagnostic compatibility check. BMS protocol calibrated to the target vehicle's ECU so the pack registers without re-coding for most hybrid applications.

FAQ
Frequently Asked Questions
▸ What capacity does the LLES-20KWH provide?
The LLES-20KWH delivers LLES-20KWH of usable energy with LiFePO4 cells at 95% round-trip efficiency. Configurable DC voltage ranges support 600V to 1500V architectures for utility, commercial, and industrial applications.
▸ Does the system include PCS, BMS, EMS, and HVAC?
Yes. LIANLI BESS containers are fully integrated with bidirectional PCS (power conversion system), multi-level BMS (battery management), EMS (energy management), thermal management (HVAC/liquid cooling), and fire suppression (aerosol or water mist). Single-point interconnection reduces on-site commissioning to under 2 weeks.
▸ What certifications and cycle life can I expect?
All LIANLI BESS products carry UN38.3, IEC62619, UL1973, CE, and GB/T certifications. LFP cells deliver 8000+ cycles at 80% DoD with 10-year performance warranty when operated within specified SOC/SOH limits.
▸ Do you ship internationally and what are the terms?
Yes. BESS units are shipped FOB or CIF via sea freight in standard ISO 20ft/40ft containers. DDP (Delivered Duty Paid) terms available for major destinations. Site delivery, cranage, and grid commissioning can be coordinated through our EPC partner network in 30+ countries.
▸ Can this BESS operate in on-grid, off-grid, and microgrid modes?
Yes. The integrated EMS supports grid-tied peak shaving, off-grid backup, microgrid with diesel/PV hybrid, and frequency regulation (primary/secondary response). Black-start capability is standard for systems above 500kWh.
