IS YOUR ELECTRICITY BILL CLIMBING FOR NO GOOD REASON?
If your power factor is low, you’re probably wasting more energy than you realise. And with tariffs rising, that wasted power is getting more expensive by the month.
You might be paying penalties you don’t need to.
Your solar system could be oversized and underperforming.
You could be forced into an expensive supply upgrade you don’t actually need.
And worst of all—you won’t even know until it’s too late.
Use our free power factor calculator now and find out what you’re really paying for.
