Reading Inverter And Charging Results

The inverter and charging tabs answer two practical questions. Can the system support the AC load you want to run, and can the battery be restored in a sensible amount of time afterwards.

How to read the Inverter tab

Start with System Voltage. This reminds you of the DC system context the inverter is being matched to. After that, the main cards to read are Minimum continuous inverter and Recommended inverter.

The minimum value is the lower technical floor. The recommended value is the more practical planning answer. If you are comparing real hardware, the recommended value is usually the better place to start.

Do not ignore the surge side

The next set of inverter cards covers startup stress: Minimum surge, Recommended surge, and Worst-case surge. These matter because many demanding appliances pull more power at startup than they do once running.

If the continuous inverter result looks comfortable but the surge side looks heavy, treat that as a real signal. A setup can look acceptable on running load alone and still feel awkward in practice because startup events push it hard.

The last two inverter cards, Inverter load percent and Surge assumptions, help you judge how hard the inverter is being pushed and how much trust to place in the surge picture.

Use the inverter graph as a quick pressure check

The inverter graph gives a simple visual view of running-load stress against the recommended inverter. If that percentage looks high, go back to the cards and read the continuous and surge results more closely.

Like the battery graph, this is a quick reading aid. The real interpretation still comes from the cards above it.

How to read the Charging tab

The Charging tab shifts the focus from supplying energy to putting energy back. Start with Energy to replace. This is the battery energy that must be restored after the scenario run.

Then read Grid charge hours and Charger efficiency. Together these set the charging problem. They tell you how much time is available and how efficiently charging power is expected to reach the battery.

Read minimum and recommended charger sizes together

The charging result gives both minimum and recommended charger sizes: Minimum charger W, Minimum charger A, Recommended charger W, and Recommended charger A.

The minimum values show the lower technical requirement under the current assumptions. The recommended values are the more practical starting point if you want more breathing room in real use.

If the charger requirement looks bigger than expected, the usual causes are high energy to replace, limited grid charge hours, or charging efficiency losses.

Finish with recharge time

The last charging card is Grid recharge time. This is one of the most useful reality checks on the page. Read it directly against the available charge hours.

If recharge time is comfortably shorter than the available window, the charging side is usually in a healthy place. If recharge time is close to the limit, the scenario may still work but with less margin. If it runs beyond the available window, the charging side needs attention.

Read these tabs with the battery result, not separately

Inverter and charging results make the most sense when read alongside the Battery tab. A battery bank can look large enough on paper but still be awkward if the inverter side is tight or the battery takes too long to recharge in the real window available.

Good habit

If a result looks uncomfortable, do not try to decide whether the problem is battery, inverter, or charging too early. Read all three together before changing the scenario.
