Solar generator sizing mistakes follow predictable patterns, and the same five errors come up more than any others regardless of budget or use case. Most of them happen not because buyers are careless, but because nearly every sizing guide available online is written by brands with a reason to push you toward the next size … Read more
Surge watts are the most overlooked spec in solar generator sizing, and they are the reason units with plenty of battery capacity still shut down when you try to start a refrigerator, sump pump, or window AC. Motor-driven appliances need a brief spike of power at startup that can run three to six times their … Read more
The watt number on your appliance label is the maximum rated draw, not average consumption. For resistive loads like space heaters, the label is close enough to use directly. For cycling loads like refrigerators and air conditioners, that same number can overstate your real draw by 40 to 60 percent, which throws off your watt-hour … Read more
Sizing a solar generator starts with a five-step calculation that gets you from your appliance list to a minimum watt-hour number. Most buyers skip at least one of these steps and end up with a unit that either falls short or costs more than it needs to. This article walks through the full process with … Read more
Sizing a solar generator comes down to two numbers, not one, and most guides only cover the first. Watt-hours tells you how long the unit will run your loads. The output watt rating, including continuous and peak surge watts, tells you whether it can start your appliances in the first place. Get one right and … Read more
If you have decided that a solar generator is the right answer for home backup, the next step is matching the right unit to your specific outage situation. Most buyers size around headline battery capacity and miss two things that matter more: whether the inverter can handle the startup surge of their critical appliance, and … Read more
Most solar generator buying conversations go sideways before they start because the buyer is thinking about power in the abstract. The one question I ask before recommending a solar generator cuts through all of that: what is the single appliance or device you absolutely cannot afford to lose if the power goes out tonight? That … Read more
Six years behind the counter at a solar equipment shop gave me a front-row seat to the same buyer mistakes playing out on repeat. This is not a guide to buying a solar generator. It is a record of the five patterns I watched repeat most often, what they cost the people who made them, … Read more
Three years ago I left a retail job selling solar generators and moved to a 12-acre property in rural Nevada where I had to actually live off one. I thought my experience at the counter would translate cleanly into off-grid life. It mostly did, except for the parts that humbled me. This is not a … Read more
