I would like to bench test my SE7600h solaredge inverter. I assume that it needs to be attached to the grid? What do you guys do?

If you want to actually do some inverting then you will need a minimum string of optimizers connected to solar modules in some light.
This is not a typical thing that installers would perform though.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNH -

Is one 120v leg attachment OK, or must I attach 240v? IMG_20190306_110042.jpg
I only made 6 of the PVM simulators, but I have more parts coming for a couple more for 8 on the string. But I am anxious to see something run.

I made some PV module electrical simulators and together with my optimizers attached to the inverter, I was hoping to find some way to simulate the grid attachment. I have seen youtube videos where they use another inverter to energize a off grid system, I am basically lazy and was looking for a easy way to fire it up.

to test run it, you have to connect it to a real grid, usually 240V
And you have to meet the minimum DC power for it to start. Then it "should" be duck soup, if the grid is good, it will convert your 400VDC into AC and backfeed the grid.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

My PV simulators are good for no more than 150w so I didn't want to burn them up trying to power the grid, would like to see then operate thoughThose who do, do it!Comment

Are you talking about using oscilliscope,and circuit analyzers and specing mosfets,caps and resistors or just the boot sequence.[/QUOTE]
Paul, I do have an Oscope, but I basically wanted to get through the pairing process. The optimizers are operational for this string of 6 (6.19vdc) so I know they are getting at least 5W to power them. I am building some 600W max PVM simulators shortly, but want to use these for the time being.
I have decided to move everything into a out building I have that is already wired with 240vac this is going to get a little bit involved. I did want to try and get the system set up on the bench while the weather restricts any installation.

You are talking about lethal voltages here, and there is no 2nd chance, no mistakes, and a messy pile of parts is not going to be your friend

Can you set up a live video feed - this ought to be fun to watch. And post the ph # for your local rescue squad, someone may have to call on your behalf

This is the way that I am used to gaining technical knowledge about electrical devices that I want to use. This picture will be confusing to a "larry with a ladder" type of installer that doesn't realize that a PV module can be electrically simulated. I stated before that I am basically a lazy guy and realize it is easier to carry around a box of PVM simulators (and cheaper) than 24 actual PV modules.
By benching my system I can have it all set up and operational before it goes outside for installation, this appears scary to the guys that are used to spending DAYS on a customers roof trying to "get it running" on the customers dime!
So today I will move this setup into my 240vac wired out building and get this organized and energized, so I can move to the next steps, I still need to determine what my PVM's and optimizers will be and I am in no rush to buy then until the weather allows for installation, I doubt that PV module prices will be increasing before then.
Thanks for your concern, but somebody has to do it
I have read many stories on this forum about installation delays due to "black box" failures that no one can explain, and it is just an accepted attitude. Sorry I can't accept that.
So I have a question, how do YOU determine if a solaredge optimizer or inverter is good or bad before dragging it up on the roof and installing it? If your answer is DUH, you might want to pay attention to this.Last edited by motorcyclemikie; 03-07-2019, 12:51 PM.Those who do, do it!Comment

Yes! I worked in the Xray business early in my career, I do have respect for "higher voltages" I know that my "bench" test arrangement without the bench looks to be a mess of wire, if you look closely you'll see that it is structured into modules.

If one module goes down A smart black box changer would tell the customer they need all new parts and change them out and everyone looks good! the customer is back on line producing energy, after a 2 month down time awaiting parts and service but his $20K investment is in operation.
One can buy these groups of "unknown" part for as little the price of the connector shells, you have to test em
To the original question, I like to run a side by side comparison on the bench and save the 30min or so to remove and reinstall the group of modules on the roof.Those who do, do it!Comment
