About this unit
Hyundai generator step-up unit built in December 2015 and never placed in service, stored outdoors in Alberta and refilled with new oil under nitrogen in December 2024, when an independent firm ran ratio, insulation and oil tests. CTG Power Systems sells it only to end users; several commissioning tests were not done and the price is on request.
