Hi @valnar - there are a few conversations in the Community regarding sizing a generator with Sense data (and why it’s not the end-all solution for this). Linking a few that might be of interest below.
Sense can be beneficial for knowing how big your loads are to get a rough idea of your generator needs, but you do need to calculate your needs separately. Below are only a few reasons.
Peak watts or aren’t always shown.
Your panel loads need to be balanced. Sense does not show how balanced your panel is. I wish it did.
You may want to use load management to reduce the size of the generator.
These are only a few items to consider and sense isn’t designed to answer these questions.
Do a search on “Generator” on the community forum. Several threads in different places on this topic, but no strong determination on whether one needs to size the generator for the absolute worst case power spikes or for the 1/2 second root mean square (RMS) power consumption that you see in the power meter. Large motors have huge inrush current and power spikes when they start up, before the windings energize, although some have run-start or compensation capacitors that reduce the spike. There’…
