AlphaESS ALPSTS-300 STS Cabinet 300 kW for TB125 Backup

A TB125 can supply loads off grid, but the switch between grid and battery is what decides whether machines, servers and cold rooms notice an outage. The ALPSTS-300 is AlphaESS's static transfer switch for the TB125: it disconnects the site from the grid and hands it to the storage in under 20 ms, fast enough that most equipment keeps running. It sits in its own outdoor cabinet next to the storage and is rated 300 kW, enough for a group of TB125 cabinets.
