Thanks all, what's the best way to monitor the amperage that the panel is drawing, does the inverter screen(s) show this, or is there something I put inline that can show the current?

Let's say you have a split phase setup of two inverters such as MPP LV6548. Together they output somewhere around 100-110 Amps. What if you had a 200A panel and the AC kicked on or something and you drew above that inverter output amperage. What would happen?

@ricardocello Thanks, so for the wireway, can i just punch holes anywhere with my knockout punch? (doesn't need to necessarily line up with those pre-measured areas? Or how does that work, I've never used a wireway before but I'm trying to make this a clean build.

Nice build, hoping I can get mine to look as clean! What are these things called that fasten the conduit to the inverter? How did you size them or do you remember the sizing for the LV6548? I need to run conduit from my wireway to my LV6548's

I have two LV6548 inverters and a 6x6 wireway. I have a couple of beginner questions, I don't know much about conduit: Knockout hole sizes: The knockout holes on my wireway appear to be different sizes side by side. If the holes are different sizes, how do I address that? Conduit and...

Thanks, hopefully someone else has ran into this same issue before. I was hoping it is just the firmware as well.

I bought my first LV6548 a few months ago from watts247 and it was branded MPP solar, I bought my second one a few days ago from them again, but this time it was branded "Rich Solar". They look identical, but I just wanted to confirm they will work together? I'm going to run them linked together...

Thank you. Something like this? https://www.grainger.com/product/22C189

Alrighty thanks, i'll skip that then. When I run the 4 hots (2 from each inverter for split phase) to my transfer switch, Do they go to separate LINE lugs, or do stack each hot from the same inverter on the same lug? Example: Here's the actual transfer switch (with generator input which...

I need 350A, 48V I believe. Six-5kw EG4 batteries. This is the only thing I've found so far but not sure if it's right. https://www.santansolar.com/product/dc-disconnect-on-off-switch-350a/ I have a 300A class T fuse there as well, but want some additional safety by being able to isolate the...

Okay thanks that makes me feel better, I'll go ahead and grap the cable then

I have a 20 foot run between my inverter and panel, I'm using two LV6548 inverters for a split phase setup. It looks like that would be ~54 amps for each separate wire run to the panel. According to the charts I've seen online, 4 gauge seems to be the best choice here, and 6 gauge would be...

@OffGridForGood This is how it's set up right now, I just moved into the place last year, and the transfer switch was already installed. I assume the Red and Black LINE on the bottom + the Neutral and Ground go out to a generator hookup, which is what I was going to sub out with my...

Thanks, here's the updated diagram with those edits if I understood correctly. What about the bonding of neutral/ground on the transfer switch?

Would that be total between the two inverters? I wasn't sure if that 153 stacks and becomes 306 from both of them drawing for split phase.

Thanks! So instead of the two - 200A class T fuses, I would just need one fuse. Since it's in line on the 4/0 cable right off the battery bank would it need to be higher amperage then? For communication, that would be the serial cable running between the two inverters and then having them set...

Plan to run this as a backup system for now, will grid tie eventually. The transfer switch is already hooked up but none of the rest is yet.

Thanks, the ISC is 13.70 for the panels, that comes out to 21.37A. Could I use a 20A breaker? Could you please elaborate on this part: In the diagram I have two sets of leads +-, +- going from the solar panels to each MPPT input on the inverter. Do you mean to run an additional ground from...

Do you mean the solar panel amps? Each set of 6 in series will make 12.81 amps at full power, so 25% would be 16A breaker which is a bit obscure, which is why I rounded up to 20 amps, is that okay? I'm going use a thick wire even though I don't need it (6 gauge underground spec).

Okay, I will start with 10kw for 200 AH. Are the EG4 batteries an okay pick? The 48V lifepo4 or newer LL version are what I was thinking of.

Someone told me that you need a redundant breaker in between the panel and the AIO, even if the panel has a main breaker, not sure though! I do have 20 amp breakers (400V DC) planned for inline between the panels and the AIO, as part of the outdoor and indoor disconnects, is that okay?

Okay good to know, I am going with LiFePo4. I will scale it up, going to start with just one and will add as budget allows

I made a diagram in Microsoft paint (sorry for the terrible artwork). Am I missing anything here (even little stuff)? I'm a beginner to solar and have been researching for a few months. The system will be totally off-grid and have no grid-tie in, with it's own separate subpanel. Thanks!
