Power a 4-ton Heat Pump (Air Conditioner) with your Delta Pro?

- In most households, the Air Conditioner/Heat Pump is by far the biggest energy consumer. I was curious if I could cool/heat my 3,500 square foot house using the Delta Pros and the Ecoflow Smart Home Panel in split phase. In this video, I give an overview of how I'm able to cool my house using my Delta Pros and what it took to get me there.
The biggest obstacle is the initial startup on most central air conditioners/heat pumps. They typically have a huge inrush of amperage that will exceed the 30amp capability of the Delta Pros. The key is first ensuring that your air conditioner/heat pump doesn't require more than a 30 amp circuit breaker. It's possible you could still see some success with a 35 amp unit or if you use a soft starter. The soft starter didn't work for my older unit but that was mostly because I couldn't get it to start enough times for the soft starter to "learn" how to moderate the initial rush.
Using a modern, higher efficiency air conditioner that doesn't require greater than 30 amps is a guaranteed way to ensure your Delta pros can run the unit.
For cooling, which you'll need most during the day when the sun is out and producing good solar input, the Delta pros can keep up quite well.
For heating, you'll likely have more issues as running a 4-ton heat pump straight out can burn at a 4KW rate and probably exhaust your Delta Pros in 1-2 hours unless you add more battery capacity.

Lost power last week for 30hrs in Tucson 110 degree heat. Used a standalone indoor “Swamp Cooler” connected to a Delta w/160w solar panel. Stayed cool in living room all day & had 85% power remaining when electricity came back yay.
2 delta pros connected to hub can handle over 14,000w surge. Either its surge is sometimes higher than that or you have a defective delta pro. You can check in-rush amps with a meter that can measure it.
Mine did it, and now it's broken.
Can one ecopro generator charge two of the delta pros connected with the 240 volt hub? Or must I buy 2 generators to make this system work?
Full disclosure, I do not have the EF generator so I can't say from first hand experience on this. My understanding is that if you are wanting to charge back up both Delta Pros simultaneously you would need two generators. They plug into the side of each Delta Pro unit and not thru the double voltage hub.
Hello, I live in Iowa as well and am considering a 4 ton GSZV9. How have you liked it? If you don't mind me asking, how much did you pay for it? How's your winter performance? Did you go dual fuel? I look forward to hearing back
Hi JT! So far, its been amazing. That said, I got it at the tail end of winter this year and I really need to thru another season to see how it performs as a heat pump. As an AC, its been amazing. Very efficient. Only during the 100+ temps in August did it run at full blast and still kept my very draft house nice and cool. I could mostly run it entirely off the Delta Pros during the afternoons. Winter I think will be different. I do have a gas furnace for supplemental heat. My prior heat pump would work until about 20F degrees and then below that the furnace had to kick on. I'm interested in seeing how low the GSZV9 can do, according to the charts it should have at least 20+% more heating capacity at those lower temps.
Did you not try adding a soft start kit to your Goodman 4 ton unit?
I did but unfortunately, because everything was hooked up to flow through the smart home panel, the HVAC tech and myself couldn't get it to start successfully in order to "train" the soft starter. I honestly think if I could have gotten the soft starter working on the Air Conditioner initially then it wouldn't have been too much current rush for the SHP and Delta Pros. Unfortunately, since the electrician had already routed everything thru the SHP already that wasn't really an option.
Can't you just bypass the Smart Home panel initially, connect the AC to the main panel for grid power to get the Micro Air EasyStart to learn first, then move the AC connection over to the Smart Home panel afterward?
I would have had to unwire the Smart Home Panel completely for that circuit so that it didn't pass thru the SHP at all in order to keep it from tripping. That seemed too tall of an ask for my limited skills. Additionally, if the Easystart ever "lost" its setting or needed retraining, I would have been back to the same boat.
@@DanielGoodwin-jq1oc OK, thanks for the quick reply. It sounds like you hired an electrician to install the SHP for you, so you didn't want to mess around with it, which is understandable. But if you watch this video ua-cam.com/video/TGpOmBm8Un0/v-deo.htmlsi=nnDC-m6h95f0zyIm on the SHP, you will see that it would have been a very simple bypass. The original wires that go to the AC unit from the original breaker were just removed and reconnected to the SHP's "out" wires. And the SHP's "in" wires go to the breaker in their place. It would have been simple enough to undo what was done (just for that circuit, not the entire SHP) and put it back the way it was to train the EasyStarter then reroute the wires again like before. If the EasyStart needs to be retrained (unlikely unless it breaks and you have to replace it), it'd be just another simple "undo", not another ordeal. I'm surprised that the HVAC people didn't suggest this. It would have been much simpler than replacing the entire AC unit.

Not a durable product, it will fail much sooner than you think.
