❓ FAQ
What’s the difference between VA and Watts?
VA (volt-amps) measures apparent power; Watts measure real power. Inverters are often rated in VA because of power factor.
Why add a safety margin?
Motors and compressors can draw 2–3× current on startup (surge). Margin prevents nuisance trips and extends lifespan.
Can I use this for hybrid/grid-tie?
Yes. Sizing principles apply; confirm inverter compatibility and DISCO rules for your location.
