Equipment compatibility check

Cali-Graf checks that the panel works with the inverter and the inverter with the battery, from the manufacturers’ datasheets. Matching models are marked Works with; a conflict stops the calculation until you choose matching equipment.

Not every panel works with every inverter. A panel whose voltage on a cold morning is above the inverter’s limit can damage it, and a too-strong panel loses power at midday. The check catches that before it reaches a proposal.

What the marks mean

MarkMeaning
Works withWithin every limit in the manufacturers’ documents.
Not ideal with your …It works, but loses some power — for example the panel is stronger than the inverter usually takes, so it clips at the sunniest hours.
Doesn’t workOutside a hard limit — the panel’s voltage in the cold or its current is above what the inverter allows.

Panel voltage is checked at −10 °C (14 °F), the coldest mornings in Los Angeles County.

When you pick something that doesn’t match

  1. Choose what to keep

    Cali-Graf asks What do you want to keep? — for example Keep the inverter or Keep the new panel.

  2. Pick the other one again

    The one you don’t keep is chosen again — the matching options are marked green. Pick one marked Works with.

What you seeWhat to do
