Customer Reviews
i have a nice memory of our meeting in Shenzhn with Deligreen Mandy and a beautiful impression of your growing company.We both are straightforward and honest people and this is the most important value,so i am sure we can

—— Angelo from Italy

I am sure we can happily work together we should easily find a way to do.Money are important but aren't the most important part.

—— Angelo from Italy

Deligreen is the partner that i have replied one for years. Some other suppliers change sales quickly but Deligreen not.

—— Bonnett from USA

i have used the batteries for 9 years from Deligreen. Amazing!

—— Phil, LA

COVID19 made something more difficult. we need the balancers urgently.Thanks for the Deligreen team's effort. We receive the balancers on time and no delay for our project. Thank godness

Safety No fire in puncture test, complete overcharge and over-discharge protection No explosion risk, but prone to leakage and equipment corrosion
Application Scenarios
1. Solar Energy Storage System

Suitable for household and industrial-commercial photovoltaic power stations. It stores photovoltaic power during the day and releases it during peak night hours to achieve "peak shaving and valley filling", reducing electricity costs. It automatically switches to emergency power supply in case of sudden power outages to ensure continuous power supply for key equipment.

2. Off-Grid & Mobile Power Supply

Applicable to off-grid scenarios such as RVs, camping, field exploration and border posts. The lightweight design facilitates carrying and installation. A single charge can meet the long-term power supply needs of multiple devices, replacing traditional diesel generators with green, environmental protection and no noise.

3. Industrial & Backup Power Supply

Can be used as UPS uninterruptible power supply and industrial equipment backup power supply. It features fast response speed and stable power supply, effectively coping with power grid voltage fluctuations and sudden power outages, avoiding losses caused by equipment shutdown. Widely used in data centers, electronic factories, medical equipment and other scenarios.
