This project comprises of two parts: A modular battery system, consisting of three identical 10 kWh units made from two reclaimed Tesla Model S battery packs (5.3kWh, 74p12s 18650 Li-Ion); and a custom-built, rackmount, pure sinewave inverter capable of delivering 20 kW peak at 230 VAC.

The system was designed for redundancy and safe and reliable field use, replacing the 8 kW portable gas generators we previously used to power our soundsystem at outdoor events.

The custom design of all components allows for features not commonly found in commercial solutions (ie. solar inverters): A touch UI shows high-res diagnostic data via a Grafana dashboard. The power stage and high voltage DC bus are optimized for supporting the high peak loads caused by the amplification of bass-heavy electronic music. A dual boost converter topology adds redundancy, allows two batteries with different state of charge to power the inverter, and enables swapping of battery modules without interrupting power
