I wonder if it’s possible to use a cool bot or something like it and use it for a walk in cooler. Would be a real game changer for someone who wants a lot of refrigeration or a market garden .

I installed the 9k Pioneer mini split last summer in my 28' RV, I love it. It's quiet and cheap on power. I've seen a review once before and would love to switch over to the 12k version. It's only $300 more than what I paid for mine. I have someone I could sell this one to. Thanx Mr. 775 for the review. Screw a plate to the wall, drill a hole in the wall and wire it up. So simple to install. Oh.. I got the Bluetooth module for mine too.. it's connected to my home wifi.. so I can control it from anywhere with an internet connection.

I have about 4 of these, 1 Deye and the others are Zamna (aka Hotspot Energy). I have been using them for more than a year now and have no complaints. In fact, we're moving one today to another location. I'll do another video of us taking it down and reinstalling it at teh new location.

I recently learned there something called a heat recovery unit that recovers concentrated high temperature heat from your air conditioner's condenser circuit and pumps the recovered heat directly into your hot water tank. I would love to see something like that incorporated in an off-grid system, because otherwise all the heat from that condenser is just wasted.

Nice, finally an affordable option for solar heating and cooling. Nice, finally an affordable option for solar heating and cooling.

When Installed my minisplit I torqued to factory spec and a year later I had lost most of my refrigerant. I called an AC guy in to refill it and he just have it some hell with a couple wrenches recharged and it’s been working great for the last 7 years. Moral of the story is don’t trust the torque specs the manufacturer recommends.

Those power readings are astounding for a 2 ton unit. It is basically 600 W for running. MY efficient dual inverter 8000 BTU unit uses that much on medium. It often runs at less than 200W. But maxes out around 1000W. It would be interesting to see the maximum draw vs minimum.

just a reminder for increasing value when limited to digging depth. Remarkably, placing panels horizontally on bottom of ditch extends the equivalent insulation as vertically installed panels. This is a technique used in crawlspaces where you can't dig down. Of course, in the basement or crawl space, this horizontal insulation extends inwardly, but I hypothesize this may work outside and horizontally outward by the same principle.

They say there are no stupid questions, but this might qualify. This question would apply to a cold climate where the average temperature is 20F in January and February. If it is possible to construct a passive solar shelter around the condensor, would that help with cold weather efficiency. I'm guesding it would be problematic or it would have been done. I realize the condensor has to have air flow, so Im thinking of something a good deal larger than the condensor itself, maybe even like a solar oven in terms of reflection.

Better to cut those flare connections off and braze in the lines with hard solder.

@@580guru Now with NEM 3.0 coming into California, adding "extra" solar panels are not an option. Yeah batteries could be used, but I would much rather go directly to my HVAC system then worry about storing energy. Things are always changing, however going directly from solar to my mini split is now more attractive then ever in California.

@Frank Marian I know NEM 3.0 sucks in that regard but it only comes into play when you deploy in a grid-tie scenario. I suppose you could start with a direct to panel setup and look to add a battery later as prices come down.

This type of unit is mainly designed for off grid buildings or for people that want a dedicated system and get their feet wet. Not everyone is trying to go off grid or think the world is ending. They just want a little light bill relief.

Your a smart man I just cant make myself understand how all that solar works.

So Engineers 775 it’s PV Direct during the day when the array generating sun power and switches over to grid at night automatically?

I'm not really happy with the 12k btu Hotspot Energy unit I bought from you, (not your fault) I will probably replace with one of these. I've been waiting over a year for promised parts for my Hotspot unit.

But what about when you aren't running it... seems like the panels would be better used in a grid-connected arrangement so that everything in the home could benefit from the panels, not just the AC.

So, knowing that you have also installed the Hotspot brand, how would you compare the two?

Did you pre pressure test with Nitrogen? And pre blow the lines?

He should have to whatever the lower of the two units max design pressure. I typically test to 300 psi for 15-30 minutes while using leak detector bubble solution.
