Frequently Asked Questions About BESS Solutions

Common questions our customers ask when evaluating energy storage systems.

What is a BESS (Battery Energy Storage System)?

A Battery Energy Storage System stores electricity from the grid or renewable sources for later use. It enables peak shaving, backup power, renewable integration, and grid services.

Which BESS solution is right for commercial facilities?

For most C&I facilities, a cabinet-type LFP BESS between 100 kWh and 1 MWh is recommended. NextG Power provides free feasibility assessments.

What is the warranty period for NextG Power batteries?

NextG Power offers a 5-year standard warranty on residential BESS and 5 years on C&I and utility systems.

How do I choose between LFP and sodium-ion batteries?

LFP is ideal for most applications with 6,000+/8,000+ cycles and excellent safety. Sodium-ion with 12,000 cycles and performs better in extreme cold.

What certifications do NextG Power BESS hold?

CE,RoHS,IEC,UL,UN38.3. Manufacturing is ISO 9001 and ISO 14001 certified.
