Yes I have seen "exterior heat load" variable in action too! The overnight load for a bedroom unit is exactly as I hoped
thx
Help me Install 3 EG4 Mini Split Solar Heat Pumps
- Thread starter MrM1
- Start date
thxCan you please clarify the “mounted E-W” setup of your panels? Are you paralleling 4 260w panels in series facing east with 4 260w panels in series facing west? Or are all 8 panels in series and facing south? Photo?
Thanks for clarifying DonF - appreciated.
Just wondering if anyone has tried a parallel panel setup with an EG4 solar mini split despite the warning on page 17 of the Installation & Owner’s Manual (“Paralleling of the solar array is not recommended as the maximum rated Array Short circuit current is 12 amps.”)?

Well another phase in the project completed.
Besides installing the 3 solar ACs and arrays for each, I'm also expanding my inverter array from 5k to 6.2k watts.
To do this I had to add splices to all my 6 existing pv cable plus add 4 more because the dual midnight solar combiner boxes (3 in / 1 out each) had to be upgraded.
So a got an 8 in / 2 out Watts 247 combiner and a steel box with terminal block bar for the splices.
Here's how it came out

Now I can install the Solar AC Breaker Box for the Solar Breakers right next to this main Combiner. But this had to be done 1st to make room for the AC Breaker box. I am going to Repurpose the Midnite Solar 3in / 1 out combiner for the ACs and use the 3 breakers, but not combine them. Just 3 separate (+) breakers for the 3 incoming AC arrays.

Are these breakers rated for AC?

I think we're off on A/C vs AC
Sometimes I have to think what I mean to say correctly on that myself

Yes midnight Solar DC breakers should be fine for the Solar side of the AC.
I used AC rated AC Breakers on the AC/AC side of the AC

That's OK I took off and ran with East West panels earlier

AC = Alternating Current
A/C = Air Conditioning

Stumbled across @FilterGuy 's white paper on overpaneling, interesting info on max Isc and so on and how it pertains to some of the lower power Sol-Ark (Deye) equipment.
You'd think as an Engineer, the MPPT that's in these units would have a familial relationship as a Deye product. Something to read and think about??

Overview of Over-paneling an MPPT controller
To get to the paper, click on the orange button at the top of the screen. There is a misconception that putting more panels on an MPPT controller than the controller is able to use will damage the controller. However, in almost all cases it is...
