Real installations, the requirements behind them and the engineering that brings them together.
Independent electrical engineering, renewable energy and power systems.
Featured bespoke design
The workshop needed three-phase power. The available connection was single phase.
Thomas Howe designed a Victron and Dyness system around that requirement, with separate grid charging, two inverters per phase and battery storage. Starting loads, options for service recovery and future expansion informed the design.
