Calculate before sharing data. Nothing entered is stored as a lead.
Edit each value from the rating plate. The bill never replaces this list or the hours.
The result answers a specific decision.
The battery answers energy; the inverter answers continuous load and surge. Both must be validated together.

Why consider surge?+
Motors and compressors can briefly demand more than their continuous load.
Is displayed capacity usable?+
The model separates usable energy from nominal capacity with conservative assumptions.
Can I back up the whole property?+
Prioritizing critical loads clarifies power, runtime and possible panel changes.
Can I edit suggested consumption?+
Yes. Enable, disable and edit quantity, watts and surge from each device rating plate.
Does the electric bill replace the load list?+
No. General consumption does not identify which devices must run or for how long.
Does the result specify a particular battery?+
No. It presents energy and power for comparing architectures; voltage, chemistry, expansion and manufacturer come later.
