About the SSRs - I've never heard of a difference. No idea if the one I have is meant to be used for an inductive load. It's just one of the normal cheap SSRs off ebay. How do I tell?Nice! That didn’t take long to figure out!..... if later you think it’s starting the same thing again, you might think about switching to a definite purpose contactor. I know SSR’s have come a long way recently, but there is a big difference running a resistive load (ie heating element) and an inductive load like a compressor. Is the SSR you’re using rated for inductive load?
I've been reading a little about the inductive-load type SSRs. It appears that I can simply add a single component to the SSR - a varistor, to accomplish this same task. A .pdf online tells me I can add a 240-270V Varistor with surge resistance of 1000A minimum. It looks like I can put it right across the load of the AC unit - jump across hot and neutral, right? Or is something else needed?Nice! That didn’t take long to figure out!..... if later you think it’s starting the same thing again, you might think about switching to a definite purpose contactor.
