Energy Storage System FAQ

Q:What energy storage solutions do you provide for commercial & industrial (C&I) projects?

A:

We offer full turnkey C&I energy storage systems, including all-in-one cabinet energy storage, liquid-cooled energy storage container, air-cooled ESS, off-grid/hybrid grid storage, solar+storage integrated solutions, grid-forming (grid-tied) BESS, and backup power storage for factories, malls, data centers, industrial parks. We support customized voltage, capacity and cabinet size.

Q:What's the battery cell type you adopt? Cycle life & warranty?

A:

We use Grade A lithium iron phosphate (LFP) cells, no ternary cells for commercial storage.

Cycle life: ≥6000 cycles @80% DOD

Standard product warranty: 5 years for full system, 8–10 years optional extended warranty for battery modules.

Q:Support grid-forming / off-grid / peak shaving / backup / arbitrage?

A:

All our ESS support multi-scenario operation modes: peak valley arbitrage, peak shaving, demand charge reduction, UPS seamless backup, solar self-consumption optimization, microgrid off-grid operation, frequency regulation. Grid-forming inverter is optional for weak grid areas.

Q:Cooling system: air cooling vs liquid cooling, which to choose?

A:

Air cooling: low cost, easy maintenance, small & medium capacity (50kWh–1MWh), suitable for mild climate areas.

Liquid cooling: high energy density, low temperature rise, long battery life, large container system (1MWh+), high temperature zones (Middle East, Southeast Asia), high continuous discharge.

Q:Can your EMS connect to local energy management platform?

A:

Our self-developed EMS supports Modbus TCP/IP, RS485, MQTT, open API docking. We can connect third-party PV inverters, grid meters, factory SCADA, local cloud monitoring platform, and provide remote real-time data, alarm push, load forecasting functions.

Q:What discharge rate do your systems support?

A:

Standard 0.5C / 1C continuous discharge;

Q:Do you send engineers overseas for installation guidance?

A:

We provide detailed English installation manual, operation video, remote online guidance free of charge. For large projects, we can arrange overseas technical engineers to site for commissioning service (customer bears round-trip flight, accommodation and service fee).

Q:What after-sales support can you get?

A:

1.24/7 online technical engineer support via email / WhatsApp / Zoom

2.Free spare parts within warranty period for quality failure

3.Long-term spare parts supply at cost price after warranty expires

4.Remote fault diagnosis, EMS program remote upgrade

5.Regular operation maintenance guidance document

Q:How to monitor the energy storage system remotely?

A:

We supply free cloud monitoring platform & mobile APP, support real-time viewing of SOC, voltage, current, power, revenue saving data, abnormal fault alarm push via message/email.

Q:Do you recruit local distributors / system integrator partners worldwide?

A:

Yes, we welcome global C&I solar/storage integrators, EPC companies, electrical equipment dealers to become our exclusive or non-exclusive partners.
