Behind gennyguide is an interdisciplinary team of developers who build an independent guide to home backup power — sizing a generator to your home, estimating what it costs, and comparing the brands worth buying. gennyguide is founded and coordinated by Christoph Ballmer, the personal point of contact for quality, ongoing development and reader feedback.
The goal is simple: a generator guide that asks for the few things that actually decide the answer, shows the result together with the method right away, and points you to the right size and the models that fit — freely accessible and with no signup.
Why you can trust this guide
Three things go into every page:
- Built from the ground up. The sizing calculator is written by experienced developers as our own transparent logic — code we can test, verify and correct at any time.
- Grounded in real specs. Wattage figures, kW classes, fuel types and typical cost ranges follow the manufacturer spec sheets and industry conventions installers actually use, so the numbers match what you'll buy.
- Explained clearly. The method is shown on the page: every running-watt and starting-watt figure, table and FAQ is written in plain language so you can follow exactly how a recommendation is reached.
How the guide is built — and checked
For a page to become something you can rely on, a few fixed rules apply:
- Documented method. The sizing calculator states how it adds running and starting (surge) watts and how it maps the total to a standby kW class or portable size.
- Cross-checked. Recommendations are validated against worked examples and manufacturer specs before a page goes live.
- Kept current. Cost ranges, model picks and brand specs are reviewed and updated as prices and product lines change.
- Honest about the limits. Every result is a planning estimate, not a quote, and a whole-house install must be sized and wired by a licensed electrician. That is stated on purpose.

About the founder
Christoph Ballmer's craft is web development and project delivery. Over more than two decades he has shipped digital projects end to end — from concept and programming through to the finished product — for internationally active companies as well as many smaller firms. That combination of development and design know-how shapes the projects of Honeygoat GmbH today, and gennyguide is one of them.
