Size Your Sub-Station, Generator, Solar & BESS in Seconds

Includes a 25% safety margin. Standard transformer and generator ratings shown are the next available size above the design load. Solar estimate assumes about 4.5 peak sun hours and 80% system performance; BESS estimate assumes 90% usable depth of discharge and 95% inverter efficiency. These are indicative figures – our engineers confirm final sizing after a site load study.
