What it draws, what it costs to run, and what a solar or EV setup actually delivers.
A different question from the rest of the site, and usually a different person asking it. Not "will this be safe" but "what will this cost me".
The arithmetic is simple and almost everyone gets it wrong the same way — by forgetting the standing charge, the tiered blocks, the tax, or the charging losses you pay for and never receive.
Power, energy over time, and what that energy costs.
Typical figures for everything in a house, ranked by annual cost.
From meter readings or kWh, including the parts of a bill that are not the unit rate.
With the DC taper that makes 80–100% slower than 10–80%.
Usable capacity after depth of discharge and round-trip losses.
Power from any two of voltage, current and resistance — then energy in kWh and what it costs to run.
kWhWhat every household appliance draws, what it costs to run for a year, and where it ranks against everything else in the house.
kWhYour bill from meter readings or kWh — including the standing charge, tiered blocks and tax that most calculators leave out, plus the effective rate you actually pay per unit.
EVHow long a charge really takes and what it really costs — with the DC taper that makes 80–100% slower than 10–80%, and the charging losses you pay for but never receive.
PVArray watts and battery bank capacity from your daily load — with system losses and depth of discharge included, which is where most sizing goes wrong.
