Calculate Solar Panel Cost For Your Home - www.solarreviews.com/solar-es...
I have been waiting for this micro-inverter for a while as I think it unlocks a DIY onramp to Solar for many homeowners. This type of plug-n-play system isn't right for everyone and won't offset all your power needs but can be a great way to start lowering your monthly power bill with the lowest investment possible.

Note: 110V, 115V, 120V... all the same thing. 220V, 230V, 240V... also the same thing. Just depends on your local utility distribution. In the U.S., voltages have trended upward over the decades because the higher voltages allow considerably more power to be transmitted on the same distribution lines. Basically these 120VAC (roughly) micro-inverters work just like normal 240VAC in that they synchronize to the line waveform that they see on the circuit. But there are a number of issues that people need to keep in mind: (1) 120VAC micro-inverters are generally NOT very efficient. 85%-90% is typical. 240VAC micro-inverters tend to run 95-98% efficient. This also means that 120VAC micro-inverters run a lot hotter than a typical 240VAC Enphase micro-inverter would. (2) You are back-feeding into just one side of the 240VAC split-phase going into your home, so the loading on the utility transformer is not symmetrical. This is typically not an issue as long as you are not back-feeding too much power since of course most normal house loads are unbalanced as well. (3) You are back-feeding into the middle or the end of a branch circuit. This is actually illegal. No, you won't get thrown into jail, but you might end up with a fine if you advertise what you are doing. It is only legal to back-feed into a dedicated breaker, with nothing else on that circuit. In addition the home must be on a solar tariff / backfeeding must be allowed by the utility. (4) Back-feeding into the middle or the end of a branch circuit BYPASSES YOUR BREAKER. This can be dangerous because depending on the topology this allows devices on your branch circuit to pull more amps than the house wiring might be able to support. This is an issue if you are plugged the back-feed into the middle of the branch-circuit. Devices sitting at the end of the branch-circuit can now consume the entire line breaker's amperage PLUS the backfed amperage without tripping the breaker. The result is that the house's in-wall wiring can catch fire. (5) There is the possibility that the micro-inverter will continue feeding devices on the branch circuit even if the breaker trips. This is obviously dangerous. -- So, that's the skinny on these 120VAC micro-inverters and why the only ones you see are junk brands. They aren't really meant for U.S. consumers. They are mostly sold to Chinese, Indian, and consumers of other countries with less robust or more expensive grids. Now if you STILL want to do this, I have some suggestions: * Never run any high-power devices on the circuit you are back-feeding into. * Dedicate the entire circuit to the back-feed.... but if you can't, then: * Back-feed into the END of the branch circuit... the last outlet in the chain, to minimize the chance of an in-wall home-wiring fire. * Note that you are still bypassing your breaker. * Do not back-feed more than roughly 500W (4A) on a 15A circuit. * Maybe consider not doing this at all. -- Typical questions: * Will the utility meter deal with one leg back-feeding and the other leg forward-feeding ? Answer: Smart meters typically handle this correctly if they are already solar-enabled (i.e. you already have home solar and a contract with the utility and the utility expects you to backfeed). Dumb meters typically won't handle this correctly. But you might want to test it because if it doesn't handle it correctly the energy can wind up being billed to you as consumption. * Will the utility company find out? Answer1: If you actually manage to back-feed power all the way to the grid, and you are not already on a solar tariff, and you have a smart-meter, the utility will know immediately and might get unhappy with you. Maybe consider ensuring that the home eats more power on that leg then you are back-feeding so you don't actually back-feed the utility. Answer2: If you are on a solar grid-tie tariff and not a solar + battery tariff, and you back-feed after sundown, the utility will figure it out and might get angry with you. * Just how dangerous is this really? Answer: It's all on you bro! I aint gonna say its safe, but I will say if you do it keep the wattages fairly low. * How many people in the U.S. use these sorts of plug-in micro-inverters ? Answer: Too many. * Are these 120VAC micro-inverters UL compliant. Answer: No. None of them are. Even if they say they are, they aren't. None of them follow the timing rules, none of them have insulation testing, none of them detect out-spec grid conditions. Most of them WILL disconnect if the grid goes down but not always... if your loads match the output they might not disconnect because most of these micro-inverters just use voltage sensing... if they are able to push the waveform too high they know they aren't connected to the grid and will stop. -Matt

[@jasonbroom7147]

Matt - You're obviously very well-versed in this and probably an installer, so I would like to ask you a question about these 120v micro-inverters. Say you built a dedicated, off-grid system, including a service panel with proper breakers, and that's where you brought the power in from a PV array. This would be 120v exclusively, powering only 120v loads, downstream from the panel...no plugging into an outlet. Under those circumstances, what concerns would you have about using these 120v micro-inverters?

[@JohnBaker3000]

Lots of great info. Thank-you!

[@junkerzn7312]

@@jasonbroom7147 In an actual professional install, or even when DIYing a large system, do not use 120V micro-inverters, ever. Simplest answer. I can pretty much guarantee you that 120VAC micro-inverters do not implement any of the standards correctly and building a big system with them will result in a fire, problems, failures, over-volted appliances... don't do it. In a dedicated off-grid system it is best to use DC-coupled (string) solar fed into charge controllers and not micro-inverters. The reason is that it is far, far, far, far easier to build a rock-solid system when you don't have to deal with frequency shifting (UL1741SA). You also want to optimize the DC path when off-grid because the battery storage is incredibly important. If you decide you want to use micro-inverters anyway (aka "AC-coupled" solar) in your off-grid system you still don't use 120V micro-inverters. You use 240V micro-inverters (98%+ efficient) coupled into a hybrid solar inverter that has a split-phase output. That gives you two hot legs and a neutral that you can put into a standard AC breaker box and pull out 120VAC and 240VAC circuits as needed, just like you get with a utility AC breaker box. -Matt

[@ericelfner]

I was thinking, this can't be legal. Thanks for the very detailed response . 👊

[@devorlast]

This kind of setup, with low wattage, could be used to power the branch with the main breaker off though. You could have a breaker facing the PV, so when you want to use it you switch the utility breaker off, switch the PV on and use the PV on that circuit only. You still have to make sure the wiring can handle the amperage but if the utility breaker for the branch is let's say 15a than having a 15a facing the PV would ensure the same level of protection. With a battery added you could use this to power some patio lights in the evening or other small loads. As long as you disconnect the utility before turning on the PV breaker the risk is minimal, mainly limited to the PV setup. Another use could be powering lights in an outdoor shed, this way you don't have to run a cable from your utility box at all and just use the PV plus battery.

Wondering if you could use to 220v non-LV model as a lower price and only use 1 leg of the 220 and get the same result. Could you just put a wire nut on the other leg? No electrician here. Also seen some Amazon “pigtail” products that split the 220 into 2 -120v outlets. Of course these are all experiments. Some commenters fail to realize this. Keep up the good work.

I read all 125 comments upto the date of this comment. Not one mention of the ability to trip the main breaker switch for grid supply to panel. In case of grid down one can manually switch off grid supply before pluggong in a solar supplied micro inverter into your wall. If taking other saftey measures in place, it may be a good back up for brown outs. The caveat is one has to have neighbors on grid to see when grid goes live again so you can reverse the breaker switches.

[@BlenderRookie]

That tiny setup would produce in a month 10% of the electric we consume. When it's comfortable and we don't use the AC, we use about 550 KWh a month. When it's hot and the AC is used, it sometimes will go up to 650-660 KWh. It would be nice to have but it wouldn't pay for itself easily. it cost $0.098 per KW here. Not even a dime. 60 KW of production during the summer per month or about $6. About 10 years the cost might be covered.

[@frostyfroze7352]

This method would be excessive for charging batteries. There are less expensive solutions that will more efficiently charge the batteries directly from the solar output.

Plug & play balcony solar kits are available in Europe, including products that can provide battery storage to offset high rates during peak hours, which increased in popularity during the European 2021/2022 energy cris. One such example would be the EcoFlow PowerStream which is not available in the US. These systems are considered relatively safe in the EU due to how the EU system works, but I don't understand the details. In the US, the standard wisdom is that a grid-tie system should NOT be plugged into a wall outlet due to safety concerns with the US how the US electrical systems work with scary talk about backfeeding & suicide cords, and thus concepts like plug & play and balcony solar kits have been frowned upon for a while. This is the first plug & play balcony system that I've seen for the US market that is UL certified. The NEP BDM-300 micro inverter has UL 1741 certification & provides NEC 2020 690.12 Rapid Shutdown for safety (Great!) & a number of other certifications. I suppose this is also safe because the output is limited -- the BDM-800 is max 800W, where a rooftop solar system will can easily be 5-20X that amount.

I have a 50amp plug in my garage that I don’t use cause the I don’t charge a EV I got a 50amp/120v adapter in case I ever wanted to use power from that outlet Would it be safe to plug my solar into that plug? I have net metering through my utility in my area that gives credits still thankfully, at least for now.

[@joeyhazlett]

I'd be very careful with that, but in theory it's possible, since that will be 240v at the outlet, and is more than likely the only outlet on that entire branch. 50A is a big breaker to trip though, so the wiring better be up to snuff. If you're not going to use all 50A, which is most likely the case, I'd recommend swapping out the beaker for a lower amperage one to something closer to your expected maximum output.

[@heroesandzeros7802]

I tried 2 different wattages of grid-tie inverters, a 1kW and a 1.2kW. Ever since I tried them, my electric bill went through the roof. The bill was $490xx last month. Neither grid-tie has been used for the last 3 months. Any ideas why? I only got about 4-5A out of the inverters. My refrigerator, freezer, pool pump, garage, shop, and carport are all on off-grid solar. The only things left are the 240V stuff: clothes dryer, stove, central AC, and some 120vac kitchen stuff. There is no reason for the utility bill to be that high and never was before.

Can you prevent sending power to the grid? If you send power to the grid then you will likely need city permit.

[@joeyhazlett]

He already has an Enphase grid-tied system that will send power to the grid, or since he mentioned that it has sensors on the main legs, it will compensate for these devices and output less from the Enphase-controlled system. If you do not have an existing system, and do not have a net metering agreement with your utility, you should not attempt to do this without understanding how exporting power works with your provider. You could definitely get charged for giving them free electricity.

[@junkerzn7312]

No, the micro-inverter has no way of knowing. If the house uses more power on that leg than the micro-inverter is back-feeding, it won't back-feed to the grid. If the house is using less, it will (at least, it will back-feed past the utility meter). A full off-grid setup is possible but generally pretty expensive. One needs an off-grid inverter that understands AC-coupled micro-inverters to provide the "utility" waveform for the micro-inverters, with batteries to soak up the back-fed power, and both the off-grid inverter and the micro-inverters must understand the UL1741SA frequency-shifting protocol.

[@junkerzn7312]

In terms of connecting a battery, it depends on the grid-tie inverter. * Always connect the battery side with an inline fuse or breaker because the inverter is expecting a solar input and will try to sweep the input, and some inverters can just about short the "solar" input while doing that. Those obviously won't work with batteries. * Make sure that the grid-tie inverter does not output beyond its rating while connected to the battery. In fact, make sure it doesn't go above roughly 75% of its rating if you want the thing to last. * Generally speaking connecting a lower-voltage to the micro-inverter causes it to output less wattage. So in terms of battery voltages, typically a 24V (25.6V LiFePO4) battery system voltage is close to ideal. 12V might be too little (not even turn the micro-inverter on), and 48V might be too much (cause the micro-inverter to output too much power and over-heat). * Do not let the micro-inverter drain the battery all the way down to BMS disconnect if you can help it. It isn't good for the battery or the BMS to do that daily. Generally speaking a solid-state DC-capable relay with a voltage sense on the battery side is used to disconnect the micro-inverter earlier, or a cheap timer on the AC side can be used to only run it for a set period of time. Do not use a cheap AC relay to switch DC on the battery side. I wouldn't even use a DC relay. I'd use a solid-state relay with a big heat sink. Most people just hook up a cheap timer on the AC side's plug since that is fairly easy to do and tends to be safer. But make sure the wattage is less than 50% what the timer is rated for. -Matt

Well, I "tested" my solar system before I got my PTO from SCE, they didn't say anything, The only thing is that I didn't get the credit for the electricity that got send back to the grid. Of course there's no GUARANTEE that they won't say anything about this.

@deyumei7965 especially if a worker is down the line and expecting power to be off in that section you're feeding 🤔

[@joeyhazlett]

@@tjmooney4181 As soon as the power goes off, this inverter will turn off and stop backfeeding. It's designed to be grid-tied, and meets UL certifications, which requires rapid shutdown when the power goes out. Nobody is going to get zapped.

A confusing video. You do not clearly show how this is to be used, You complicated things by showing your roof top system, etc. It is not clear what someone should do with the AC output of the system

[@everydaysolar]

The AC output just plugs into a circuit in your home. I recommend an exterior GFCI outlet with an "in use" cover on a dedicated circuit where you are only feeding in the solar and not powering anything else on the same circuit.

[@travismorgan9273]

How do you keep it from feeding back to the grid and receiving credit for it?

[@WalterRiggs]

What is an “in use” cover?

[@whenmullet2674]

@@WalterRiggs A plastic cover that fully closes and allows a cord to be plugged in at the same time. All newer exterior outlets have them. The older outlets only have a "door" type cover that works with nothing plugged in, but is not sealed when a plug is in so it's not watertight.
