How To Compare Equipment Using Equipment Check
Equipment Check is a separate comparison tool on the results page. It does not change the stored result. It compares real hardware values that you enter against the requirements of the scenario result you already calculated.
What Equipment Check does
The app marks this section clearly as Optional comparison only. That description is important. The calculator result remains the source reference. Equipment Check is there to answer a practical follow-up question: does the real hardware I am considering look suitable for this scenario?
This is useful when you already have candidate batteries, an inverter, a charger, a controller, or a panel choice and want to compare those items against the current result without recalculating the whole scenario around that hardware.
Before you start
Equipment Check only makes sense once you understand the result you are checking against. Start by confirming the correct version and scenario on the results page. Then review the Battery, Inverter, Charging, Solar, and Solar Controller tabs so you know what the scenario is actually asking for.
Once that is clear, move into Equipment Check and enter the hardware values you are actively comparing.
What to enter
The form is split into three sections: Battery, Inverter & Charging, and Solar Panels & Controller.
In the battery section, you can enter: Selected battery unit voltage (V), Selected battery unit Ah, Selected battery unit kWh, and Selected battery quantity.
In the inverter and charging section, you can enter: Selected inverter continuous power (W), Selected inverter surge power (W), Selected charger current (A), and Selected MPPT charge current (A).
In the solar and controller section, you can enter: Selected panel wattage (W), Selected panel quantity, Selected panel Vmp (V), Selected panel Voc (V), and Selected MPPT PV input power (W).
You do not need to fill every field every time. The most useful comparison is the one that matches the hardware you genuinely want to assess. If you only want to check an inverter and charger, focus on those fields. If you are comparing a full battery-plus-solar package, then a broader entry makes sense.
How to read the comparison
After you click Run Equipment Check, the app returns a summary and then a set of section-based comparison cards.
The summary shows an overall status and counts for Suitable, Borderline, Undersized, and Oversized. Below that, the app breaks the comparison into section cards and field-level checks.
Each check shows the field label, the status, the Selected value you entered, the Reference value from the scenario result, and a short message that explains the comparison outcome.
Use this to screen candidate hardware quickly. It is a strong way to narrow options and spot obvious mismatches. It is still not a replacement for final compatibility validation, manufacturer checks, or installation review.
