Frequently asked questions
What's the difference between a BESS system and a BESS project on Wattilla?
A BESS system listing is the hardware itself — a containerized or utility-scale battery unit, typically from a manufacturer or integrator, sold as equipment. A BESS project listing is a development site (land, permits, grid connection) with or without a system already specified. Both live on Wattilla; use whichever matches what you're buying or selling.
What BESS technologies are listed?
Primarily LFP (lithium iron phosphate), the dominant chemistry for grid-scale storage, alongside other lithium-ion variants where sellers list them. Each listing states the technology and configuration (containerized, modular, etc.) where known.
Can I buy a BESS system directly from a manufacturer on Wattilla?
Yes — system listings come from manufacturers, integrators and resellers. Sign in to view full specifications and contact the seller directly, with no broker fees or intermediaries.
