Question 1

What type of lithium battery do you offer?

Accepted Answer

We utilize lithium iron phosphate (LFP) battery chemistry. LFP offers high current rating, long cycle life, good thermal stability, and high safety compared to other lithium-ion batteries.

Question 2

Do you use brand new battery cells?

Accepted Answer

Yes, we utilize brand new battery cells from TOP 10 global cell manufacturers to ensure high cycle life and longevity of our batteries. Only the highest quality cells are sourced for our battery modules and packs.

Question 3

How long does it take to fully charge a 10kWh battery?

Accepted Answer

Approximately 5 hours for a full charge from empty to 100% state of charge. The actual charging time depend on the output power of battery charger.

Question 4

How long will a fully charged 10kWh battery power a home?

Accepted Answer

On average, a 10kWh battery can provide 1-2 days of power for typical home usage before needing to be recharged. The actual duration depends on the home's energy consumption.

Question 5

Can I let the battery completely lose its charge?

Accepted Answer

Do not allow the battery to drain completely as this may reduce the overall life of the battery. At minimum, charge the battery every 6 months.

Question 6

What is the recommended depth of discharge (DOD%)?

Accepted Answer

We recommend not discharging the battery beyond 80% depth of discharge (80% DOD) for optimal battery life. Limiting the depth of discharge to 80% helps extend the number of cycles the battery can provide.

Question 7

Can the battery data be monitored via Bluetooth on a mobile app, in addition to the PC monitoring software?

Accepted Answer

Yes, we offer a Bluetooth-enabled mobile app for iOS and Android to monitor battery status, usage graphs, warnings and errors.

Question 8

Is the software upgradable remotely?

Accepted Answer

Yes, the software can be upgraded remotely over the air to continuously improve features and performance.

Question 9

What is the maximum number of batteries that can be connected in parallel?

Accepted Answer

Up to 16 battery modules can be installed in parallel for expanded energy storage capacity.

Question 10

What warranty do you provide?

Accepted Answer

We provide a 10 year warranty for our complete battery storage system covering defects in materials and workmanship.

Question 11

How long will the battery last?

Accepted Answer

Our lithium iron phosphate cells are guaranteed for 6000 cycles. Based on one cycle per day, this translates to over 16 years of service life.

Question 12

Can your system operate off-grid?

Accepted Answer

Yes, our battery storage system works both on and off-grid. Just add solar panels for fully off-grid renewable energy storage.

Question 13

Do you provide online technical support?

Accepted Answer

Yes, our technical staff provides 7 days 24 hours online support.

Question 14

Can your batteries be customized based on client project requirements?

Accepted Answer

Yes, we have customized many storage systems with various requirements for clients in different countries. Our experienced engineering team can design customized battery solutions tailored to each project's unique specifications.

Question 15

What is the applications of low voltage (48V) and high voltage lithium ion (LFP) batteries in energy storage field?

Accepted Answer

Low Voltage 48V Lithium Ion (LFP) Batteries: Residential solar PV storage - Used to store electricity from rooftop solar panels, typically around 48V. Small-scale backup power supplies - Provide short term backup power for office and household electronics. Indoor storage systems - 48V is more practical than higher voltages in confined spaces. High Voltage Lithium Ion (LFP) Batteries: Large-scale solar PV and storage power plants - Used to stabilize and optimize renewable energy grid integration,
