NiceIndeed!! Thx Gary. That works
As you suggested, I did use different times 1 minute apart for the action.
I think it's always been there. It never occurred to ME, that it would work in an essentially independent fashion outside the Solar Air Conditioner app, to send commands to the A/C. Darn glad you questioned this.The Scenes control does seem to work though. Did they App Developer just add this, or did I just miss it in the App?
Indeed. That's my problem, plus the degrees F to degrees C change everytime you switch control from remote to App on 12k BTU units (how come only i seem to have THAT problem...?). I control them habitually with the App, while wife and son use remotes.This happened to us in the middle of the night once. Wife used the remote to turn the unit on, but made no other changes. Within an hour we were burning up
Mai i know if you have a link to the wall bracket on your 24k unit? Thanks.DIY Tools you'll Need:
XtremePower 3.5 CFM Pump and Gauge Set
- I used this but sent it back because the Gauges were pretty crappy and the pump did not seem strong enough ... but the A/Cs has worked perfectly for 3 months so I must have done it right.
I Replaced the Gauges with ...
Master Cool 59161 gauges
- Excellent for the DIY'er
- Made in USA
- I have since used these gauges to service 2 other A/C units for friends
And when I need a pump, I will most likely get ...
VIVOHOME 1/2 HP 5 CFM
- Yes the combo is less, but I think you are getting better product with these 2
Pump Oil
I got This Reamer for the Copper Pipe, but I think the "Typical" Style Reamer might be better. But this worked fine for all sizes
Wostore Eccentric Flaring Tool Kit
- This is an excellent tool and worked perfectly EVERY TIME
- Make sure you put a drop of Nylog Blue on the cone of the tool for each flare
- Makes a very clean and perfectly shaped flare
Nylog Blue
- This is a MUST
- Put a drop on the Flare tool Cone before each flare
- and then a drop on the back of the flare between the nut and flare
- and a drop or 2 on the fitting
- Make sure you "smear" it in and around the surfaces
- This is a MUST to prevent leaks
Ridgid Pip Cutter
- You might want the larger one with the spring
- But this is a great Little Cutter
Vacuum Port Adapter
- These are the one's for 410a and the EG4 units
- Your size needed may vary
Extra PVC Wrap
- If you run out, or need more, or what came with the EG4 does not match your house color
Good Tape to Start and End the PVC wrap
- I used this tape to start and then overlapped so you did not see the tape
- Then at the end, I taped it and the taped end is up in the Line Set Covers
Various Size Air Conditioning Copper Pipe Extension
- If you need to run the line set further than what you have
- I used these and worked perfectly
- You can get copper at a home center or AC supply house
- But if you have multiple units, Install the shortest run first, and save all the copper for the longer runs
- This is what I did and worked out so I did not have to buy extra copper
If the array for this unit were to be installed on a house then what would be the best way to install rapid shutdown when there is no inverter? I have a 12k btu unit on the way. I'm debating on having the array ground mounted or on the roof. The roof would be idea, but I'm not entirely sure about the rapid shut down requirements.
Did this ever get sorted out? I have this setup (separate off-grid panels dedicated to mini-split, no inverter) but my 24K unit isn't receiving any solar per the app. I have 6x380w Silfab panels and Tigo TS4-A-O optimizers and CCA - these are wired directly to my exterior unit. I checked and I got 218.5V at the MC4 connectors that feed the EG4, so it seems like it is getting plenty of voltage. I also have it setup for grid power which is working perfectly fine. Tigo told me everything looks good from their side too. I have a message into Signature Solar to see if they have any troubleshooting tips. Could I have an MPPT issue?I'm curious how the answer to this plays out
How new is your instl?? i.e. "installed yesterday " or you've run it enough that your startup could not have, by chance, run across the "low solar" timeouts???but my 24K unit isn't receiving any solar per the app
Thank you for the reply! I just had gotten the panels installed on Easter Sunday due to rainy weather this past month. My mini-split got installed earlier in March.How new is your instl?? i.e. "installed yesterday " or you've run it enough that your startup could not have, by chance, run across the "low solar" timeouts???
Otherwise, perhaps you DO have the "bad MPPT" problem you mention / @MrM1 encountered. Sounds like you've got DC power checked OK, I assume as you say you'd have an indication if after connection something was shutting it off on the TIGO side.
The TIGO stuff does look super cool for module-level RSD. Something external would still have to trigger it for DC arc fault though right?? I am sure expecting any next-gen EG4/DEYE Solar A/C to include AFCI / GFCI UL1699...
Thank you again! In the million pages on this amazing thread I missed that lol. I will give it a shot on a full sunny day as I’m sure I tried it in succession with not enough time in between power downs.Basically as long as unit is on and not displaying LP, should be seeking Solar per the schedule on 3) of this post attached. MrM1 had the only well documented MPPT problem (so it obviously can happen), there has been 2 to 3 other guys saying they had some cloud troubles but never posted any setup pics or stuff to try to help them - one guy did add panels and was good then.
I think most cloud "problems " are having to do with arrays on the low end of the suggested power requirements - you seem fine
My 12k unit was still running while it was SNOWING, much less cloudy ️
Thanks for pics, looking good DC in EMT on stucco / Clay tile seems pretty safe
