jehugarcia It’s officially referred to as split phase in the US for residential power. It’s ‘single’ phase, since it’s a single phase off the grid run into a center tapped 240V transformer. Both legs give you 240, but one leg to the center tap is 120. So you technically see two apparent phases inside the house, but it’s still called single phase, or split phase service.
@ericspda

US residential power is 220V single phase with center tap, but this inverter is 220V single phase. There is no center tap, it is not designed to use or operate on 120v. It does not need a neutral, just a ground. Plenty of international gear will work just fine with American split phase power, as long as it says L1, L2/N then you’re good to go. But neutral is only required if something internally relies on 120V, otherwise it’s just ground and the two hot legs. In this case, the leg marked L2/N is going to have 120V on it with respect to ground, so connecting that to ground is going to both put 120V on ground and short out L2.

@@marzsit9833 You are correct about North American residential wiring, but I think you are mistaken about most European standards. Here in NA we have 240V split phase, which is two "hot" leads 240V apart, with a neutral from the transformer centre-tap which is typically grounded somewhere. This gives two, 120V hot leads, 180 degrees out of phase and a neutral of ~0V, or it can be used to supply 240V across the pair of hot leads for large appliances like electric ranges and dryers. In contrast, all European residential supplies are 220-240VAC single-phase, with one of those lines being the neutral (~0V), and the other the 'hot' lead. This can theoretically cause problems if you try to connect European devices to 240VAC North American outlets that use something like a NEMA 6-15P. The outlet provides the correct voltage, but if the European appliance has used the neutral power lead for case grounding, then this will be extremely dangerous here, since it would become a live, 120V connection wrt ground! In practice, I don't think this actually matters much, if at all because in most of Europe, _unpolarized_ 220VAC outlets (2-prong, with no size differences) have been used in residential circuit wiring for a long time, so I doubt very much if any appliance that relied on the neutral to provide case grounding would satisfy European standards either, since that would be equally unsafe (more so!) Therefore, although _theoretically_ there is a difference (in that if you measure both leads wrt true ground, the systems would appear different), in practice, it doesn't matter.

For Europeans who understand yellow 240 v to 110 volt site transformers and the way they work for safety purposes, the US mains system is often (but not always) working in a similar way. It's just that with the yellow site transformers which have a centre tapped transformer there are two 50 volt AC lines referenced to the centre tap which is connected to ground. The 110 volt supply (European yellow transformer) is taken ACROSS the two output lines which (due to the centre tap) are 180 degrees out of phase so it's not two phase but split phase. In the US they have an almost identical transformer connection but giving split phase 240 volt (each half of the output transformer giving 110/120 volts referenced to ground at the centre tap. This gives a 180 degrees out of phase output across each winding, so that 220/240 volts is available ACROSS the output connections (NOT using the centre tap) but with a max of 120v to earth as a consequence since the neutral/earth is connected to the centre tap. Quite a neat system to overcome the current/power limitations of a straight 110/120v only supply which is a bit alien to Europe but common place in the Americas generally (and other parts of the world too).

@wu ming The voltage goes almost to max with barely any light, but fluctuates with temperature. It's the current (amps) that is affected by how much light it is getting. You need to calculate your max open circuit voltage (Voc) on the coldest day of the year (using the panels temperature coefficient) and make sure you stay under 600V. You also want to check what it'll run on the hottest days to make sure you stay above the minimum 230V. As an example, for where I live (gets very very cold, but also hot in the summers) I would need 9-12 panels attached in series to be in the desired voltage range.

I eventually want to have a room in my house that has European power from a 50hz unit and the rest of the house on 60hz. There'd be a solar pannel setup just for the EU system one. I want to collect tech from around the world and would like a way that won't ruin the tech by just stepping up 120 to 240 at 60hz i know most newer tech doesnt care about hz as much. But I have some other projects I want to test and it would make it much easier to have the native output. I was looking into ac-dc-ac converters that have a very good sinewave output as an option till I can build my dream home.

Grid tie inverted check for a source signal and then sync up to that signal ( your grid connection) before they will output power. If you had a full sine wave inverter that it could sync up to , then perhaps.

It is call anti islanding and is a legal requirement for a grid connect inverters, they only output power when they can detect the grid. The inverter has to match its output frequency to that of the grid. As soon as the grid goes down the inverter automatically stops output.

Inverters are vastly more complex in operation than solar panels, so they tend to not last as long as the panels themselves. It’s possible to design a inverter to last a very long time, but it would be massively more expensive so it’s not done. A good inverter lasts typically 15-20 years, so it’s not really like they’re swapped out too often. Some of the lower cost or poorly designed ones might last closer to 10 years, whereas a solar panel can have a practical life beyond 30 years.

Instructions say in lieu of this password, a call to Danfoss is necessary. If we are DIY-ing it, got a suggestion for the installer code?

And then I added wind turbines and two back up generators one gasoline and one gasifier. I make enough electricity to run every thing in my house like I was still on the grid.

You get what you pay for in inverters, the premium inverts have a low failure rate and expectational customer service, the less you pay the higher the failure rate and the less customer support. your better off buying cheaper panels than a cheap inverter, single string inverters have a lot of current flowing through them, a poorly constructed 1 could burn your house down.

Hi Jehu. Thanks for the great video. I like these inverters. But my question does a bms exist that can handle the high voltage 240v. How would you protect your battery bank if you rewire it to 240v instead of 48v. Any input or links would be helpful. Thanks

You would need to design a BMS capable of such voltages. The question is though, why would you even contemplate running those sorts of voltages on a battery bank? The cost of components and the time cost to engineer such a unit would greatly outweigh any benefit, of which I can't think of a single one.
