Can you leave a power station plugged in all the time?
EcoFlow, Jackery, Anker, BLUETTI and DJI each give different advice on staying plugged in, storage charge and top-ups. What each manual says, model by model.
Do solar panels work during a power outage?
Grid-tied solar must stop feeding the grid within 2 seconds of an outage, even in full sun. Why, which systems still give daytime power and what a battery adds.
How many solar panels to charge a power station in a day?
Per 1,000 Wh: about 184 W of panels in a Phoenix June, 823 W in a Seattle December, before charging losses. The maths, input limits and when one day won't do.
Watts vs watt-hours vs surge watts, explained
Watts are what a power station delivers at once, watt-hours what it stores and surge watts the short start-up peak. How to read all three on a spec sheet.
The guides help you choose and size a power station. The blog covers the questions around that choice: what the numbers on a spec sheet mean, what rooftop solar does when the grid goes down, and how to look after a station between outages. Each post links to the maker's own manual or a government source for its figures, and ends with the guide or tool that turns the answer into a decision.
