Help me Install 3 EG4 Mini Split Solar Heat Pumps

There is also some " throttling" of the compressor that happens depending on either time of day or outside temp. (I'm guessing temp). My 24k will go up to almost 2000 watts in the afternoon when it's 85, but at 75 at night outside, even if you set the temp to 61 (and it's 75 inside), it will not use more than 1300 watts
 
12k BTU units on sale..(I personally bet that means DIY lineset Solar units inbound). Just a little more than non solar now..

With SS, never panic buy because of a Sale. If it's not on sale, wait a week. It will be.

When I bought mine "On Sale" the day the sale ended, they were back on sale with a different sale the next day.

And now they're on an even better Sale 6 weeks later.
 
So all 3 Units are up and running. I plan to start a video tour of the 3 professional installs maybe as soon as today. But I will not focus on the Professional install that was totally done by a professional, No - I will focus on this DIY window valance I am going to build to cover the line set over the 1 ton 12k unit installed professionally over the window by a professional.
 
So Saturday, the Professional HVAC tech was still installing and doing finishing touches on the install and AC/DC wiring to the Units. So on Sunday and Monday, were the first full KWh tests usage.

Keep in mind there are NO solar panels connected yet, only AC. And the AC is being supplies by my 5100w array, the 32KWh of LFP battery storage, and my Lil' SW 4024 Inverter. I will have solar panels connected Professionally in the next several weeks, but for now, just AC and the AC is powered by my off grid system.

House Specs
- 2300 sq feet
- Poorly insulated not on grade with no insulation in the floor
- Main house has a 3 ton Heat Pump 14 SEER
- West facing Florida room and 2 bedrooms are supplied by a 2.5 ton Heat Pump 14 SEER
- Only R4 insulation in the ceiling of the florida room
- I had installed two 24k EG4s in the living room and Florida room and a 12k EG4 in the bedroom
- I run the blower fans of the 2 main heat pumps on circulate mode meaning the fan blowers turn on 35% of the time

Amazingly, with an outside daytime hi of about 80F+, keeping my house 73F thru the day (something that was impossible before these 3 mini splits). Here is how many KWh's I used from the POCO the past 2 days. The Utility is going to wonder if I'm home. LoL

KW usage first to full days with no solar.jpg
 
Those numbers (which will not stay that low all the time) ... but those numbers if they held daily would work out to be about $0.91 per day and about $28 a month for my POCO Utility bill at $0.15 per KWh. (NOTE: $0.15 includes my KWh costs, connection fee and taxes)

THATS AWESOME. I think there are probably systems people spent twice the money on not doing as well :)

Of course, the Solar problem is you can:
Spend 10% of $, get 50% of benefits
Spend 50%, get 90% benefit.
But wow - to me - to get that last 10% to full
Off Grid = :eek:
 
So here it has started. The final part of the Finishing up of the 3 EG4s. Once I dress up this final unit's install, it's on to the roof and the install of the solar panels

But as you have seen before, I wanted to have the 1 ton 12k installed over the center of the window. This created several cosmetic problems. So ...

The Problem ...

I have a similar location over a similar window.
Luckily no valance. I'm just going to remove the curtain rod. The curtains are never closed. I'm just going to hang them individually on either side. They are just decorative.
 
Alright ... here it is. Ahead of Schedule. But I was in too much of a hurry to get it up before work tonight to shot video. So no video of the build and install.

I think it came out pretty nice

Anyone using the ac limiter? Just wondering how low i can go with the ac input to keep the unit running during the day. I have the eg4 12k just got it up and running today so haven't had a chance to play with the settings.
 
I used it in the winter, but I have the 24k. On VERY bad days, this would result in 300W Grid + 300W Solar, which was ok output.

As of June 1st I'm also turning AC grid back on (with Limiter, at least as frequently as I remember to TURN IT ON - as I said previously it has to be turned on EVERY. STINKING. DAY. lol - if someone finds a setting or way to make it permanent PLEASE SHARE :))

Reason for turning grid back on. I have had some clouds pass after 5 pm when I think the Sun is now BEHIND the panels. So, it has shut it off - it always restarts in my case, but it does appear the delay is 20 minutes - not so good. We'll try this and see how it compares.

MARCH-APRIL-MAY Spring I've done 100% off-grid with great success. Plan to do that again in Fall.
 
Yes I have experience that you must turn the AC limiter on every time the unit is cycles off and back on.

We all need to go into the app review and leave it as a feature request

Great Idea, I was trying to figure out where to get attention for that. This is really my only "complaint" personally with the product. I ran numbers, I am 2.9 Mwh under yearly avg use to date - with ONE SIMPLE PRODUCT connected to 7 panels.

Looking forward to your Solar installation/ upgrade :cool:
