Customized Solutions:

Modular cabinets, all-in-one (inverter + battery + PCS) systems, and 20GP/40HQ container solutions available.

Core advantages of our HV lithium battery

1. Global Tier-1 lithium battery cells 3.2V 100/280Ah- Ganfeng Lithium.

Ganfeng Lithium is a global Tier-1 lithium battery supplier that has won the honorary title of "ranked 5th in China and 6th globally in 2022 energy storage shipments".

Guaranteed positive tolerance:

100Ah cells deliver 103Ah (3% over spec);

280Ah cells achieve 300Ah (7% over spec), maximizing ROI through extended runtime.

Meanwhile our battery support adaptation to high-voltage inverters, such as Deye, Solis, Growatt, etc.

2. Strict Quality Assurance & Factory Testing

ü Screen defective batteries, such as batteries with insufficient capacity, high internal resistance, or other defects;

ü Perform charge and discharge tests to stabilize battery performance, which helps the internal materials of the battery to reach a stable state and minimize performance fluctuations during initial use;

ü Improve consistency, ensure that the same batch of batteries remain consistent in parameters such as capacity, voltage and internal resistance, enhance the overall performance of the battery pack and extend its service life.

ü Verify safety performance, whether there are safety risks such as overheating and leakage during the charge and discharge process, and ensure safe use of batteries. Each battery’s test report will be provided.

3. Smart High-Voltage Control Box

UE High-Voltage Control Box includes:

Premium components: Nader circuit breakers (trusted brand) for 10% longer lifespan vs. generic alternatives.

Advanced connectivity: Configurations of Bluetooth, Wifi, and the screen can facilitate users to check the battery status remotely when there is a problem with the battery, quickly and accurately locating and solving the problem.

Competitor Comparison:

Feature	Our System	Standard Systems
Display	✅ Integrated	❌ Often excluded
Remote Monitoring	✅ WiFi/Bluetooth	❌ Limited or none
Component Quality	✅ Nader Breakers	❌ Generic brands

4. Original Ganfeng Factory Battery Modules welded: Precision Engineered

ü Reduce variance

Voltage variance: ≤10mV per module (vs. 20mV industry standard)

Capacity variance: ≤5% (3% tighter than competitors)

ü The cycle life can ensure about 20% higher than the conventional self-welding.

ü Tighter temperature control: ≤6℃ delta during 0.5C charging (vs. 8–10℃ standard).

ü Welding tightness, the double cross laser welding process adopted by the whole module ensures 0 false welding during the battery welding process.
