This is a grid tie inverter that is 200 watts. It actually reads a bit higher for various reasons. This was to see how well it worked. POWER INVERTERS.

Maybe I missed it…but unless you have the main breaker turned on how will the power from your inverter go back into the grid unless that receptical you pluged into bypassed your electrical panel?
Hi Dan, I wish if …
Hi Dan, I wish if you try to do this experminet with the grid tie inverter (hopefully is possible)
Well do just the same thing but switch on a load with less power than the inverter, so everything should be off and just the load on, lets say 100w and see if the consuption is still running backwards. In this way you can see if you are really generating back power. Thanks and Keep it up

Dan, have you tried focusing a parabolic lens on a solar panal?

a small wind tubine can help as well in case it is storming or cloudy…
Yes you are right. …
Yes you are right. 200w /h needs 5hours for 1kWh but.. as you noticed his meeter just turned over to a new kWh.. that means it should only need a couple of Wh to go back one number again… But meeters on the market has this feature that they wont go backwards. For that you need a new meter… I have the same problem in my house…
And guys.. for this to work you dont need any batteries! It’s enough with solar panels and this inverter! Batteries only costs money and is not ment for this.
Hi Dan,
I really …
Hi Dan,
I really like your videos. I have one question about that meter and your 40 or so minutes of 200w. Correct me if I’m wrong but a KWH is 1000 watts for one hour. and the meter reads KWh so you would have to run that inverter for 5 hours to work up to one KWh. But the process of turning the power around and running it back up the wire is true.
I finally find out …
I finally find out that i need at least 1,000 watts of use a 12 hours a day, what will be a good advise for my needs?
ok, wow 4000 watts …
ok, wow 4000 watts of wolar panells will be a lot of money to invest. let me see if i am clear … what equipment i will protect with those fuses? they must be on the heavy wires side between the batteries and the inverter?
video is great …
video is great thanks for doing what you are doing i just bought a sunwize 4 panel used solar unit with 5 batteries and a charger contrler how would charger the batteries and tie into my house at the same time is there a video or a dvd that i can buy
I have a question …
I have a question how long have you been running this inverter, my friend has one from April now the fan on the back has stopped working today in June
Make sure you have …
Make sure you have very heavy gauge wire and place a solid set of fuses. Your wattage of panels should be 2x what you expect to use in a day. So if you are running 2KW solid then you would need 4000 watts of panels to go grid free.
If you only need short bursts of power, then you can charge 1 day and run for a bit the next.
if i have a wagan …
if i have a wagan 8,000 watts inverter and i buy two deep cycle batteries of 12 volt and i connect them parallel what amount of watts of a solar power i need to make it work properly and what else?
The efficiency of …
The efficiency of these inverters is about 80 to 85 percent. A battery charger is much worse. Would actually cost more to run.
Great Video!!! One …
Great Video!!! One question though. You said that it’s not a good idea to connect 2 of the Harbor Freight panels in series. Why is that? If you purchased 2 sets of 3, (total of 6 panels) couldn’t you connect 2 sets of 3 in parallel and those 2 sets in series? That would give you 24 volts and a higher wattage output.
My 4kW 240V …
My 4kW 240V inverter has a range of 212 to 264 volts. The utility company isn’t going to go outside that range. Really bad things can happen to stuff that’s plugged in if the grid voltage goes outside that range. I mean, things can burn out or blow up.
So no, the utility company isn’t going to turn up the voltage just to keep your 200W inverter out of business.
True but of the …
True but of the grid pushes more than inverter can supply, the inverter no longer exist.
My 4kW grid-tied …
My 4kW grid-tied inverter works the same way. If the grid power goes down, it shuts off.
However, there’s also an inverter AC disconnect mounted outside (near the meter). I guess the reasoning is that it’s better to have a physical disconnect switch, so you’re not relying on the circuitry in the inverter in a situation that could kill someone. In other words, a single point of failure should never result in an unsafe situation.
A grid-tied …
A grid-tied inverter senses the voltage and frequency on the AC side and makes its output match.
I have a 3.5kW …
I have a 3.5kW grid-tied solar system with a net-power meter. Yes, it really runs backwards during the day.
Those squares on the display each represent one watt-hour. The faster they ‘move’ the more power you’re using. They move backwards when the PV is feeding the grid. (That’s how my meter works, yours is probably the same.)
at the end the …
at the end the batteries will die? or you can add with that same electricity from the power inverter to a battery charger and from the battery charger to the batteries so you have a circular endless cycle of producing and extracting energy from the battery to the power inverter?
Wow, these grid tie …
Wow, these grid tie inverters are EXPENSIVE on ebay. I’m guessing much cheaper than any sold by government vendors in Canada Ontario. We have a neat Provincial incentives program for feeding back to the grid. I hear it doesn’t pay off for almost a decade.
Be nice….?
Be nice….?

RIght quad but that would be retail price.If you produce it rhen you are paid 20$
lol. not true at …
lol. not true at all. of course, rates vary from location to location. most people pay about 50 cents a kilowatt-hour. up here in Ontario, Canada, a new program increases government payout for rooftop PV solar systems to 80.2 cents a kilowatt-hour.
you should hook up …
you should hook up a 200w load at the same time, then after a few hours if the meter hasn’t changed you know the inverter works.
