round-trip efficiency

All-in-one commercial and industrial storage. AC-coupled, so it retrofits to sites with existing solar without touching the PV installation.

Twelve units combine through multi-AC coupling for roughly 1.2 MW and 2.8 MWh, which makes it the basis for both single-site installations and standardised rollouts across a portfolio.
