Sizing is the upstream decision. Get the kVA, derate and battery picture right before quoting or auditing.
Get the kVA, derate and battery picture right before you quote or audit. Sizing is the upstream decision; everything downstream improves when sizing is correct.
Build order: sizing → audit → intelligence → diagnostics → solar/UPS → library.

Signature tool: enter loads + quote + budget; get a verdict, missing items, safety risks, and a 10-year cost comparison against cheaper-safe and premium alternatives.
