Frequently asked questions
Plain-language answers on sizing, power factor and project delivery.
How is the right transformer size decided?+
It is not a fixed kW-to-kVA table. We use the connected load, demand and diversity factors, power factor, planned expansion and a target maximum loading, then select the next standard rating. An engineer reviews the result before any proposal is issued.
What is a PFI panel and why would I need one?+
A Power Factor Improvement panel switches capacitors to reduce reactive power. A low power factor can attract utility penalties; correction also reduces the apparent load on the transformer and cables.
Do you handle installation and commissioning?+
Yes. Moon Star supplies, installs, tests and commissions transformers, panels, generators and solar systems, and provides maintenance support.
Can you maintain equipment that you did not supply?+
Contact us with the equipment details. Maintenance of third-party equipment is subject to an inspection.
How do I request a quotation?+
Use the consultation form or call the support line. Share your project location, approximate load and the equipment you need; we will confirm any missing information and send an itemised quotation.
Are the estimates on the website final?+
No. Any estimate is preliminary and subject to engineering review and site conditions.
