OVERVIEW

Why choose Flash for Battery Storage

Flash designs and integrates lithium-ion Battery Energy Storage Systems (BESS) — from home hybrids to MWh-scale firm-power projects.

Our systems use LFP chemistry with cloud-based BMS, thermal management and grid-forming inverters for round-the-clock renewable delivery.

From residential 10 kWh hybrids to utility-scale MWh containers, every BESS we deploy is built for 6,000+ cycles and 10-year performance warranty.

FAQ

Questions we hear a lot

Why LFP and not NMC?+

LFP offers 3× the cycle life, better thermal safety and lower cost — ideal for stationary storage.

Can BESS pair with existing solar?+

Yes — we retrofit AC-coupled BESS to any existing solar plant without rewiring the array.

What's the round-trip efficiency?+

Typical system RTE is 90–92% including inverter and auxiliary losses.
