I do that. The cold air return plenum in the basement has a finned register that we keep open, draws in cool basement air (which is dehumidified, too) and distributes it thoughout the house. We put the furnace fan on to do this. ------------------------------ Mike Curran Retired EE --------------- ...

Our house is partially surrounded by trees and we're in a rural area so it often cools down enough at night to open the windows in the back bedrooms and run a window fan at the opposite end of the house. By morning it's almost cool enough that the A/C doesn't come on until late in the day, if at all. ...

This thread https://community.ases.org/discussion/solar-panel-upkeep-and-maintenance mentions your issue. Perhaps Ken Nadsady may be able to point you in a helpful direction? ------------------------------ Mike Curran Retired EE ------------------------------

I had similar results for May, best May ever for PV here in NE Ohio. Not as good as yours Bill but I have some shading issues and (I believe) less capacity at 16.5kw. Total net export for May was 891 kwh ------------------------------ Mike Curran Retired EE ------------------------------

I'm going to disagree with Bill on this one. The off grid guys I know (through the Outback Power user forum) all pretty much use their systems to run well pumps, A/Cs (many are in warm climates), even large power tools. The secret is in having an inverter sized large enough to handle the starting current. ...

"In person though, the Lucid is absolutely beautiful." Yeah, saw one in a Bed Bsth & Beyond parking lot a couple months ago. These pics don't do it justice. ------------------------------ Mike Curran Retired EE ------------------------------

Yesterday at noon my grid power returned after being off for around 20 hours, the result of a severely windy Saturday (3/25) here in NE Ohio. I have two battery backup systems (one supports a wood-fired hydronic heating system that cannot be allowed to freeze in winter) and they got me through this period ...

Nice job Kyle. My only comment is that on meters that measure both import and export, export is usually not exactly what your panels are producing, since some of that production gets consumed by your house. Other than that, good work! ------------------------------ Mike Curran Retired EE --------- ...

Fyi there are no CTs in my Enphase system. Works by some sort of powerline communication between micros and gateway. Wifi provides data to the app on your phone, tablet or PC, and connection between gateway and web (edit) is hardwired. App totals the energy produced from all the micros so noCTs are needed. ...

Enphase offers a gateway device (I think the app is called Enlighten) that communicates with each microinverter and gives lots of data. I have their M215 micros (pretty old tech) on my barn roof. Screenshot from today (not a good solar day here) attached and more available at https://enlighten.enpha ...

Is it possible you are confusing "consumption" with net use? On my bills, my supplier shows a graph of import without taking export into account (see screenshot). In your case it's very possible consumption is your export (edit) import, only. Since most people don't have grid-tied solar, utilities haven't ...

Hi Kyle - Fyi, here's a link to the public site for my Emphase system https://enlighten.enphaseenergy.com/public/systems/Hctc107221, which covers 2 larger arrays plus a single ground mount panel for comparison purposes (steeper angle for winter compared to other array roof mounts). The earliest array ...

Hi Rich - Yeah, I get that. I also have a Vue Gen 1 monitor but because my solar array breakers are remote from the panel where the CT's are, I don't have them monitored individually and the resulting data is really hard to interpret and perhaps meaningless. Here's a screenshot: Note there are 2 electrically ...
