500 kVA padmount and kiosk transformers
500 kVA is a common size for smaller commercial sites, solar installations on single buildings, and EV-charging sites with a handful of DC chargers. At 433 V, full-load current is roughly 670 A.
If the network or your site needs a unit sooner than a new one can be built, a surplus or refurbished 500 kVA unit can close the gap. Check the voltages, vector group and DNSP requirements first.
What to check
Primary voltage and tappings
Vector group (often Dyn11, but confirm)
Oil type and bunding needs
DNSP acceptance of a used or refurbished unit
Nameplate and test records
FAQ
Can I use a used 500 kVA unit on a DNSP connection?
It depends on the network and the unit; your ASP designer and the DNSP decide.
Is 500 kVA enough for my site?
Your designer sizes it from the maximum demand, plus any future solar, battery or charger load.
