Understanding Warnings

Warnings are part of the result, not decoration around it. They tell you where the scenario becomes less comfortable, less certain, or more dependent on assumptions.

Why warnings exist

GridGap is meant to be useful without pretending to be final. If a scenario relies on generic assumptions, pushes a component hard, or sits close to a practical limit, the warning system is there to say so.

A warning does not automatically mean the result is wrong. It means the result should not be read casually.

How warnings appear in the app

Warnings are stored with the saved result. On the results page, you will see them in two places. Scenario cards can show a warning count, and the dedicated Warnings tab groups the stored list by severity.

They belong to the version and scenario you are looking at. Switch versions and you switch warning sets too.

Common warning themes

Warnings usually cluster around a few themes. One is assumptions. That means defaults are still carrying too much of the scenario and the result would benefit from more specific real-world input.

Another is performance stress. That includes heavy battery depletion, thin reserve, aggressive recharge expectations, or inverter loading that leaves less comfort margin than you may want.

Solar scenarios can also produce warnings around weather sensitivity, panel-count cleanup, or controller-side limits.

How to read them properly

Read warnings alongside the metric cards, not after them. A battery count, inverter size, or panel count may look tidy on the Overview tab while the warnings show that the answer rests on weak ground.

A useful question is simple. Does this warning change my confidence in the result, or does it just tell me what to validate next.

If several warnings point at the same subsystem, treat that as a pattern. Repeated battery warnings usually mean the storage side needs another look. Repeated charging or solar warnings usually mean the recharge path is under pressure.

When warnings should slow you down

Warnings matter most when the scenario is close to a decision point. Early on, a result with some warnings can still be useful for comparison. Near a real purchase or installation decision, the same warnings should carry more weight.

For homeowners, they are a reminder that professional review still matters before acting on the output. For installers, they are a prompt to validate the scenario more carefully and not treat the calculator as the final word.
