Already seeing significant savings despite my PV system having only been running since the last week of June.

We've been running the house on mostly PV since I got the initial install done at the end of June. I ran some smaller loads from it throughout June while I was testing the equipment, but that was kind of ad-hoc.

Just now coming out of a heat wave that started last Monday, and most of the A/C usage has been from solar. Still running from the "temporary" transfer switch hookup, so I'm not yet taking advantage of the "hybrid" aspects of the inverter. That may be a while since I have to do some more prep work before I can start installing the new breaker box and moving circuits over to that.

I've also ordered the fourth rail and 5 more panels, so I should have this upgraded from a 3KW to a 4KW system sometime later in the week. Would have ordered those earlier, but I didn't want to make the UPS guy deal with them when the heat index was 109 degrees lol. That, and I wouldn't want to deal with them in that kind of heat, either.

It's just nice seeing such significant returns this early in the process.
