How many watt-hours you need for home backup is not a fixed number. It depends entirely on what you’re running, how long the outage lasts, and whether you have a realistic way to recharge before the next overnight stretch. I’ll walk through the exact duration math for three common scenarios: 8-hour, 24-hour, and 72-hour outages. … Read more
Apartment renters are often surprised to find that their backup power situation is more straightforward than a homeowner’s, not harder. A smaller load profile, no viable gas generator option, and simple wall-outlet charging means a portable solar generator fits apartment living better than most renters expect. This article covers the three constraints that shape every … Read more
Most buyers who try to price out whole-home backup end up not buying anything. They run the calculation, get a number they did not expect, and walk away from the purchase entirely. Critical loads sizing solves this by asking a different question first: not what can I power, but what genuinely cannot fail without real … Read more
“Whole house solar generator” is one of the most searched phrases in this niche, and one of the most consistently misunderstood. Whether a portable solar generator can cover your whole house comes down to one question you have to answer first: do you mean covering your critical loads during a short outage, or running your … Read more
Can a solar generator run power tools? For most residential-grade tools, yes, and the reason most people get this wrong comes down to a concept almost no sizing guide mentions: duty cycle. A circular saw draws 1,400 to 1,800 watts, but you are not running it continuously for eight straight hours. Understanding how tools are … Read more
Sizing a solar generator for an oxygen concentrator is not like sizing for a refrigerator or a phone charger. The draw is higher, the runtime requirement is longer, and the consequence of getting it wrong does not stop at a warm fridge or a dead battery. This article covers the real watt draws by flow … Read more
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
