Which peak shaving battery systems are known for modular, scalable design and fast installation?

Peak shaving battery systems that are commonly recognized for modular, scalable design and fast installation include:

• Tesla Megapack – Large, containerized, pre-integrated system designed for rapid deployment and easy scaling.
• Fluence Gridstack / Ultrastack – Modular utility-scale BESS platforms built for flexible sizing and streamlined installation.
• Wärtsilä Quantum – Containerized, modular battery energy storage system with factory integration for faster commissioning.
• Sungrow PowerTitan – Highly integrated, modular liquid-cooled system intended for quick on-site setup.
• CATL EnerC / EnerOne – Standardized containerized storage products known for scalable configurations and fast installation.
• ABB / Hitachi Energy grid storage solutions – Modular systems often deployed in container or skid formats for easier expansion.
• BYD Battery-Box / utility-scale container systems – Scalable architecture with standardized modules and relatively quick deployment.
• Powin Stack / Centipede platform – Modular utility-scale battery systems designed to simplify project expansion and installation.
• Delta Grid-Scale BESS solutions – Containerized, modular offerings aimed at rapid deployment and flexible capacity planning.
• Eos Znyth / other modular alternatives – Some vendors offer stackable or building-block designs optimized for phased expansion.

If you want, I can also narrow this down by:

1. best options for industrial peak shaving,
2. lowest installed cost, or
3. systems with the shortest lead time / fastest commissioning.
