I'm using my EG4 18k with a critical loads subpanel. This morning, I turned off the panel's 100A breaker, cutting power to all circuits. Yet, the status of the EG4 LCD screen still showed 130W of usage to the home. What gives?

Hello all. Newbie here. I've been watching a lot of YT videos recently from 'DIY Solar Power with Will Prowse'. In a recent video, he showcased an inverter with AC input. That got me wondering if it's possible to run a PV setup without batteries*? The theory is that if there's enough sunlight...

This is a picture of the service lines coming off the transformer and into the meter on my house. Why are the cables from the transformer coupled onto thicker wires? Is this some code requirement that the lines into my house be thicker gauge? Why would that need to be if so? If the thinner wires...

I need to run wire from panels on roof, about 60ft, through attic space, to unfinished garage to inverter. There's an "attic tunnel" which connects main house to detached garage. Do I have to use #10 "PV wire" through the attic or can I transition in the roof box to standard #10 THHN wire?

My wife and I are having this debate on which would be better for keeping the house cool, and keeping electricity bill low. There are 2 options: Purchase a high-efficiency window AC unit (12000+ BTU), and place it in the living room. Solar+battery will keep this running 24/7, blowing cold air...

I found 'EZ Solar JB Rooftop PV Junction Box' on Amazon, from a YT recommendation. $60. This can't be the only solution? What are some other options when needing to transition from roof into attic space?

Hello. Newbie here. I'm having a hard time understanding how a grid-tied inverter setup works without completely rewiring my main breaker panel. Here is my rudimentary diagram. My electric company does not do credits for surplus. Still, as I understand it, a grid-tied system can "slow down" the...

Hello gang. I'm looking at buying a kit from GoGreenSolar, primarily because they offer permitting, blueprint design, code compliance, etc (ie: they do all the paperwork for the local city). Most of their kits are string-inverter based, or micro-inverter based. My question is actually about...

Per title, I have an EG4 18kPV and 8 x 370W panels. (Vmp 34.2V, Imp 10.82A, Voc 41.0V). The spec sheet on the EG4 says the following (it has 3 MPPTs): * Nominal Input Current : 25/15/15A * Max Short Circuit Input Current : 31/19/19A * DC input voltage range: 100-600 VDC Right now I have the...

Is there a way to avoid all this wasteful conversion? You've got solar panels sending DC to an inverter, which converts to AC, goes into the breaker, to the outlet where my server rack UPS is plugged in, which converts to DC for UPS battery storage. When the power goes out, the UPS converts DC...
