One question, one page, one answer
65 questions, each given its own page and answered in the first sentence rather than after four paragraphs of preamble. Where the true answer is that a published figure was measured under conditions you will not meet, the page says which conditions and stops there.
Choosing
Which class of machine answers the need at all: a power station or a fixed installation, a generator or a battery, a balcony kit or a roof.
Capacity & runtime
What watt-hours buy, why usable capacity is smaller than nominal, and how long a given load actually runs on a given battery.
Power & surge
What a continuous rating allows, what a surge rating means with its duration attached, and why a big battery behind a small inverter starts nothing.
Solar & charging
What peak watts are measured under, how an input window decides whether a panel charges at all, and how fast a station refills from sun and from mains.
Batteries & chemistry
LiFePO4 against lead-acid, what a cycle count means without its capacity percentage, and what cold does to a lithium bank.
Wiring & connectors
Cable cross-section against current and distance, which connector meets which, and why a thin lead undoes a good inverter.
Protection & fusing
What a fuse actually protects, why a DC rating is not an AC one, and where a breaker or an isolator belongs in a circuit.
Measuring & monitoring
Why voltage only guesses a state of charge, what a shunt counts, and which meter answers which question.
Installation & rules
What a maker states about mounting, earthing and registration, and where the local rules take over from the product sheet.
Generators & fuel
Rated against maximum output, runtime at a stated load, noise at a stated distance, and what a maker says about running one outdoors.
Vehicles & off-grid
Charging from an alternator, what a smart alternator changes, and what a fridge really costs over a day in watt-hours.
Maintenance & lifespan
Storage charge levels, what shortens a battery, what a firmware update can change, and which parts are sold separately.
When it goes wrong
A panel that never charges, an inverter that trips, a station that shuts down warm, a monitor that reads wrong from the first day.
