C&I Energy Storage FAQ: This page answers the most common questions about DJENERGY solutions—from LiFePO4 battery cells to All-in-One air-cooled BESS and containerized BESS. Learn about sizing (kW/kWh), safety, EMS monitoring, PV/grid/diesel integration, installation, delivery, and warranty.
What products does DJENERGY manufacture?
DJENERGY focuses on LiFePO4 prismatic cells, HV packs/racks, all-in-one C&I ESS, and containerized BESS solutions for commercial, industrial, and grid-support applications.
Do you support OEM/ODM for energy storage projects?
Yes. We support OEM/ODM branding, electrical customization, communication mapping (as required), and documentation packages aligned with project delivery.
What are the advantages of LiFePO4 (LFP) batteries?
LFP offers strong thermal stability, long cycle life, and a high safety margin, making it suitable for stationary energy storage and backup power.
What is an All-in-One C&I ESS and where is it used?
An all-in-one system integrates battery, PCS, EMS (optional), protection, and thermal management for peak shaving, backup power, PV integration, and load shifting.
What are the main applications of containerized BESS?
Containerized BESS is used for peak management, renewable integration, backup power, frequency support, and microgrid/off-grid hybrid systems.
How do you manage temperature in containerized BESS?
Thermal management typically uses HVAC and system-level controls to keep the battery within safe operating ranges and protect cycle life.
How scalable are containerized BESS solutions?
They are modular. Capacity can be expanded by paralleling multiple containers with coordinated protection and site-level controls.
What information should I provide for a quotation?
Please share power (kW), energy (kWh), grid voltage/frequency, PV/diesel topology, application (peak shaving/backup/etc.), and site conditions.
Do you provide FAT testing before shipment?
We can provide a functional test checklist and verification records depending on the project scope and delivery package.
What documents are included with delivery?
Typically: datasheet, user manual, wiring diagram, commissioning checklist, and packing list. The exact set can be aligned with your project requirements.
What warranty do you offer?
Warranty terms depend on product category and contract. We can provide standard options for C&I ESS and containerized systems based on application and expected cycles.
