Estimates, not exact specs
Our calculators use typical values for common appliances. Your actual fridge, pump, or inverter may draw more or less than the average, so treat every result as a starting point for planning. Before you buy, check the rating plate on your own equipment and work from the real numbers printed there.
Not professional advice
Nothing on this site is professional electrical, financial, or legal advice. We explain how backup power works so you can make an informed choice. We do not know your home, your wiring, or the rules where you live. For decisions that carry real risk or real cost, talk to a qualified person who can look at your situation directly.
Accuracy
We try hard to keep prices, specs, and guidance current. Even so, products change and mistakes slip through. We do not guarantee that everything here is complete or up to date at the moment you read it. If you find something wrong, tell us and we will correct it.
External links and advertising
This site links to other websites and shows advertising. We do not control that content and do not endorse everything in an ad or on a linked page. If we ever add affiliate links, where we might earn a commission on a sale, we will make that clear. Ads and links never change the advice we give.
Limits of our responsibility
You use this site and its calculators at your own risk. We are not responsible for any loss, damage, or injury that results from actions taken based on the content here. That includes buying the wrong equipment, installation problems, or anything that follows from them.
