Calculation method
Transparent energy calculation
Daily balance = solar + generator − load; autonomy includes deliverable battery
Only the displayed values are used; no hidden tariff, weather profile, equipment curve or incentive is added.
Worked example
Three complete starting scenarios
Complete essential circuits scenario.
Daily balance = solar + generator − load; autonomy includes deliverable battery
Supported inputs
Precision and limits
No live assumptions
This is transparent planning arithmetic. It does not retrieve live tariffs, weather, equipment specifications, incentives, safety limits, code requirements or professional approvals.
Estimates remain scenarios
Actual consumption and cost can differ because of weather, occupancy, controls, maintenance, tariffs and equipment performance.
Safety and compliance
Electrical, fuel, pressure, combustion and installation decisions require applicable manufacturer information, codes and qualified professionals.
