So this micro inverter output is 240v split phase (two hot legs L1/L2 ?) or just one hot leg with 240v ? If its two hot legs does this means from ground or neutral you’ll see 120v off each hot leg? I mainly use NEP micro inverter, seems like it maybe the same as this one?

I looked at the specs. The IQ8+ is rated 240v 290VA out continuous. That's an output of 1.2A. You're already maxing out the output. If you want more solar power then you'll need more inverters or an inverter with a higher output rating. Also, for a permanent installation you'll want to fuse the lines and add disconnects when you feed the compressor. You could also add batteries that are charged by the solar power during the day but are used to offset the power at night.

I am a retired electrical engineer, and what you are doing is technically correct. You are adding a grid-tie inverter to the circuit to CONTRIBUTE to the power being drawn by the AC unit. You will never come close to power draw that the AC unit needs, and its only inserted when its running, there is no chance you would ever inadvertently export to the grid. Since the micro-inverters are designed to require a grid to sync with before they will export power (anti-islanding) there is no safety concern. Also no way the utility will ever know.. Before I became legitimately connected to the grid, I made a far more sophisticated system consisting of current sensors and outputs from my thermostats to control how many panels were connected to my inverter depending on the load. That way i didn't have to completely disconnect the grid until the total house load was less then what a single panel produced. Super nerd project. I ran it like that for over 2 years until the official connection was made, and now I'm legal! Endphase inverters want to see a gateway, so it would be better to use the cheap Chinese micro-inverters that don't spend time looking for a gateway. Also, switching the DC side will get the power to the AC unit with a shorter delay, but you would have to control an external relay to do so. Make sure you provide a disconnect of some sort so you don't confuse the poor AC tech who is trying to fix your AC unit when it fails in the hottest part of summer! BTW. The best thing you ever did, was install the soft start unit to the AC. They are pricey, but worth it. A final word of advice: Just because you CAN do something, it doesn't necessarily mean you SHOULD do it. You have to be the judge. I tend to live on the edge myself, it keeps things interesting.

People getting hung up on thinking the 2 panels are supplying all the power. They are not! They are just reducing what the grid has to supply. No different than if the panels were tied to the breaker box and every time the ac kicked on he turned on the solar breaker. Wattage is wattage. If your panels produce 400w then your overall grid usage will go down 400w. Nice way showing initial draw and then the supplied amperage and overall amp draw after the micro inverter kicked in. 👍🏻👍🏻 Before I installed my full array, I did this same thing to see if it would work. It did and my home energy monitor helped prove it as I could see my overall grid usage drop when the panels were producing. The electric company had no idea for months.

@@Branx86I have solar and worked with the electric company when they setup my meter. They had no idea I had solar hooked up for the previous 2 months, I was supplementing power to see how much it would produce and a way to reduce usage without the extra bi-directional meter fee. Producing exactly what I used or up to double my usage would save me money. Producing over double my usage cost me more. After the couple of months I had them out to inspect my setup and reprogram my meter to be bidirectional. I found in my situation it was more beneficial to just let my panels work vs trying to supplement and track output and usage.

I've been doing hacks like this for a decade. The problem with most grid-tie inverters is that they follow the legal mandate of waiting 5 minutes before exporting power, so unless you are in a particularly hot climate, that misses most of the AC cycle. There are lots of options to get around that, but the point of this video is that it is the cheapest way to do this.

The HVAC industry could eliminate grid power with self contained package minisplit AC units....they already have soft start circuitry and draw much less power...plus as zone ACs they could be programmed to automatically ration Air Conditioning to priority and low priority zones when solar power drops. The AC would pull grid power only when insufficient solar hours exist. If the collective world was really worried about what they said they are, then that would have been the first mandated upgrade to heavy appliances in the 1980s and 90s. As it is, the design described above would triple ir quadruple the cost of a minisplit install...which would require years of payback...which may not be covered by the lifecycle of the unit.

The challenge with this is that the inverters will "push" their output higher until the inverter is putting out as much power as possible. This will feed back into the 12v to 220v inverter, and cause it to either shut off, or burn up. The "mains source" needs to be a lot more powerful than the grid tie inverter(s)... by at least several times. IOW, if you want to use 1000 Watts of solar through grief tie inverters, your main source of "artificial grid" needs to be at least 3-5 times as much power. In a case like this, those IQ8 inverters can actually form their own micro-grid on their own... but you need their other equipment to control the IQ8 inverters, as this is a special mode that has very strict requirements. ... or just buy a Hybrid Solar Inverter - that can do both Grid-Tie (grid interactive), or off-grid operation as needed... though that usually requires a storage battery to fill-in the gaps when cloud cover would cause a loss-of-solar black-out.

Maybe consider getting a solar power station, plugging your window ac into that and then connecting solar to the power station. Would probably be more useful and an easier solution for a window unit. You might consider the Anker Solix C1000. Here’s a link to my review and testing of that unit.

This might could be a great partner to a regular solar system with batteries. (Less panels needed, less batteries, less stress on all of it too) On bright sunny days your battery charging system would end up mostly dedicated to charging batts for your night time use, cause the "partnered" reduction of grid power use, solar set up would be handeling the day time heavy draw stuff. Set it up wisely so in a SHTF / you loose grid power, You could easily unwire the panels from the grid side and add them to your battery side....

Definitely some good thoughts and ideas here! Thanks for watching!

This is pretty cool! I didnt see you test the voltage after you connected inverter to the contactor while the disconnect is still unplugged. When the contactor is off, the microinverter should not energize the compressor but could the capacitor have enough current to "trick" the microinverter making the system live even though the contactor is off? Also the solar energy from the panels is wasted when off, so having a battery or some other way to use the energy would be good to get more use out of the panels.

Maybe it's possible that capacitor could fool the inverter for a minute...but it takes a few minutes of the grid being present before the inverter starts producing, so I don't think we need to worry about that. And yes, it would be best to not only be producing power when the A/C is on. But solar panels are cheap, batteries are not. So if you could run your A/C for "free" even though you're leaving power on the table, that might be enough for some people. Or start by just offsetting your A/C power bill and apply your savings to the cost of a battery down the road. Thank for watching!

I’ve seen those cool and save units. What you said is right about the evaporative cooling providing better heat transfer for the A/C unit. My only gripe with that is the minerals in the water. I really don’t want to have to try and clean minerals from my condenser coils. One thought would be to capture the condensate water from the A/C and then pressurize that water through the misters. That’s essentially distilled water since it was in the air and then got condensed. So that solves the mineral issues, only problem now is that you won’t get very long sessions of misting that condensate water because you’ll evaporate it faster then it can condense. Got to contemplate this concept more. In any case, huge thanks for watching and commenting!

Because just like you said through condensation and evaporation we get rainwater it's supposed to be pure water, that might do the trick for you.

Since you're not offsetting when the A/C is not running and there is a ramp up time for the inverter, this would seem to discourage frequent cycling.

Your test appears to be on a single stage air conditioner (the type that tends to cycle on and off numerous times most summer days). It looks like you could do the same with a modern inverter driven heat pump that works at moderate power levels without needing to cycle off numerous times and is able to work all winter long.
