Uhm, I bought two gs to get 12k, so either I can't use charging to get my 12k or if I use my chargeing and only get 6k and not split. Geesh, I do got a 120v to 240v stepup transformer. I think its the 5k model, could I just run the gen to it then take the two 120 outputs and pull from each L1 and l2, cause I checked and its split on the output and run that to the input of the gs? Would that solve the problem?
Oh you can get 12kw total...just the "master" has to have a 120v input for the generator (max 3kw input, as it's 120v), and a 240v split-phase output. "Slave" has to be set for 240v input; this will get you the full 6kw output across 240v.
If you need more than 3kw from the generator, you'd need to bump the generator output up to 240v to get the full 6kw charge of the "master" inverter.
Hopefully your house is fairly balanced across the phases, as the "master" inverter would be doing a fair bit of "autoformer" action to produce the Neutral (as the "parallel" unit doesn't provide the Neutral line).
Okay, lets break this down. I still hook up both the two gs to the main each on its own 50a 240v breaker. a Black wire, and yellow wire I think is the l2 color, then the white wire and go to the neutral bar, I do this for both circuits in my main.
Both GS are setup as master and slave.
and far as I know my breaker is balance, since all 240v is basically on one side of the breaker and all the 120v breakers are on the other side.
Now what do you mean about the neutral wire? That would be the job of both inverters wouldn't it? I mean its the power source, so you got to have a neutral comeing from it. The Generator would be I think a floating neutral , not sure I know its a inverter generator, so basically like a third inverter, since its putting out pure sign wave.
your throwing me off on the 3k and 6 k lol parts.
If your meaning that it would only charge at 3k level, that is fine with me.
Almost sounding like I'm going to have to find a high amp 24v charger and just run the generator to charge the bank instead of use the gs to do it.
wonder where I can get a cheap 24v high output charger for cheap, I don't want to use my flycow it can push 10 amp, but, that would take forever to charge a bank.
I'm just trying to figure out exactly what you're trying to do, and provide a suggestion for how the inverters need to be configured to best meet your needs. Bit of confusion resulting from it, I think.
- Yes, you connect both GS inverters to the breaker panel, each on a separate 240v breaker. You'll be fine with a 30A breaker on each (unless you already have 50A breakers), as 6kw / 240v = 25A.
-
First inverter is set up as the master inverter, the System Mode is left at the default "Normal."
- 240vAC split-phase output
-
120vAC single-phase input, for the generator.
- Due to the 25A transformer current limit, the 120v single-phase input will limit at 120v * 25A = 3,000W.
-
This inverter also can control generator start if so desired (automatic gen start based on battery voltage)
- 3kw @ 24v is 125A; I have yet to run charge tests on the GS inverter, but it's possible we might be able to charge @ 80A without overheating. There are much greater losses in charge mode than inverter mode, due to the system using the backsplash diodes on the FETs for rectification (which drop 0.6-1.0v)...this likely will thermally limit the maximum charge current. But way over 10A, that's for sure!
-
Second inverter is set up as the slave/paralleled inverter. System Mode is set to "SLAVE: Parallel".
- 240vAC split-phase output, not connected
-
240vAC single-phase input, connected to the breaker panel for parallel backfeed. Only 2 wires go to the panel from this inverter, NOT the neutral wire. Why? I don't have a big enough relay to disconnect 2 legs of the transformer at the same time...and if Neutral is connected, the inverter is not able to completely disconnect the input power source. Might be possible with parallel mode, but definitely not grid-tie.
- If Neutral is not connected, the transformer in the Master inverter will still produce Neutral from the collective power.
Hope this clears things up for both of us?
Yep, so I still get 12k output to the main, but limited on chargeing since basicly I'm only useing 1 hot wire,, but at 125a charging thats is perfit anyhhow since the gen is a 30a max anyhow, even at 25a that won't over load the generator.
yes, I keep forget to do the math on conversion, for some reason in my head I thinking l1 is 25a l2 is 25a so the breaker for a 240v would be a 50a since a 240v breaker is nothing more then two 120 that are made into one throw switch. Unless your saying the breaker rating is 25A but is two 25A lol that might be where my confusion is. 😛
because to me 12k is 100A if you converter 12k by 120v w/V=100a
So Master, gets Yellow, Black and Nutral wires ran to the main
Slave gets yellow and black run to main from input side of gs
The gen gets hooked up to master on input side l1 and Nutral wire,
Master/slave/gen gets grounded.
Sounds about right.
Next we should talk about that grounding setup. Sticking rods into the ground can do more harm than good. There's two kinds of grounding at work here: Equipment grounding, and equipotential earth grounding. They are different things that perform different functions but are tied together at the service entrance. It's unfortunate that they are both called "ground". There's sooooo much confusion around it.
