Oh yeah, duh. Geez, I'm such a noob. Ok, so yeah, your original post is accurate. I can't get anymore panels, that are an exact match to the ones that I have. I guess I can look online and find something if I need too. I'll wire them up then as you described and I guess I'll just see if...
Hey Robby, This is great info. Again, I really appreciate you taking the time on this. I wish I could treat you and your partner to a dinner or something. Please let me know if I can.
I was out all evening and have to work all day today away from my computer so I haven't had a chance to...
I have tried to find someone local with no luck. I have posted many post here but I do not have the time to learn electrical engineering and most folks here are operating on such a high level that I cannot make sense of the answers. I realize I have made the mistake of buying gear Will said...
Hey there, sent a reply to Robby, this might be redundant but wanted to reply. Thank you for 'buttin in". I appreciate anyone on here that takes the time to help me. So I'll send the same screenshot I sent to his reply. I think it's 250voc, but please feel free to advise if you think I'm...
Ha! Thanks Bluedog, it is indeed. robby has been really helpful with the diagram he drew up for me. I still need to get my panel setup sorted as well as the subpanel but I'm kind of going one step at a time. I'm going to start installing the panels next week and as long as what robby drew up...
Oh awesome! That's so good to hear. I didn't want to have to try to return what I bought. I think it might be too late anyways. Ok, well, false alarm it sounds like. Thanks again robby. I'll definitely let you know as I progress on this. Take care!
Thanks for your help. I've been doing just this. I'm trying to find someone locally that can hold my hand on this stuff. I used to work at an internet service provider and people would call with questions and my boss would go on about RX rates and TCP/IP, packet loss, etc. I would then get...
the bottom is an alternative way to group them, didn't know which would be best as I didn't know if the + - could be different lengths, see what I mean?
Thanks! I thought so. just saw your email about the junction boxes. Duly noted. Thanks. Ok, last question! Take a look at the pic I included, do I just need fuses on the + ? And on the two groups on the left, since I do have two groups in parallel facing slightly different directions...
Hey everyone, So I bought two 48V 3000TL growatts and two signature solar 100ah lithium batteries and after spending all morning trying to find info on how to install these I am finally giving up and posting here. Will has a video where he has one of each of these and he shows it as a really...
Perfect. Thanks. So I guess I'm ok on not using fuses then as I'm only putting 2 strings together but I should get blocking diodes for the two that are facing slightly different angles. Would I be getting two diodes? One for each + string coming from each group or just one on them after...
Hey Tim, this is from a while ago but I am looking to get some fuses per this older discussion. I have a 5S2P set up sending 205 Vdc at 19amps into a Growatt 3000 LVM inverter. I attached the specs for it. I'm wondering what amperage I should get for the fuses. I called the place I bought it...
Hi there, I have 20 48v panels I'm wiring up in two groups of 5S2P to go to two inverters. So ten panels to each inverter. The panel set up is a little funky as the roof space I have is separated a tiny bit. I included a drawing of how they're going to be installed. Hopefully that helps. Do...
Thanks guys. I guess what I'm realizing is
Hey thanks, I have seen this guys videos. He was the first one I found. He has so much other stuff going on, transformers and cut off switches and all this stuff that I guess I thought wasn't needed if I bought these. It's part of what got me so...
Thanks for the reply! I have pretty much watched every video Will's put out. I'll go back and try re-watching some. Maybe I'll see something that I missed. Cheers!
Hey Robby, Clay again. Hope you don't mind. So I included a pic of the specs in the manual. You had posted above regarding the preferred 5S2P, "I would have felt more comfortable with a 5S2P which would be 207Vdc and working Voltage of 166V with Aprox 19 Amp. That is nicely inspec with this...
Just had a thought, does the solar need to be identical on each inverter? Maybe my thoughts of how to do it on my last post won't work. They would be running in split phase parallel operation.
So I was able to get a hold of Signature and he said that the 18 is not a hard ceiling and that the inverters will just only draw 18amps. Said I couldn't hurt them. Told him I'd be running 207vdc into them at 19amps (assuming the panels are putting out full power) and he said that would be...
they are slightly. Not much I can do about it but it's not that much of a difference. otherwise they're all pretty much the same as far as shading goes. Nothing over them really. Open all around. Thank you.
I posted earlier about trying to use two growatts with two signature solar batteries to charge my tesla like Will does. If I run them in split phase for 220 I can't use them for anything else correct? This is the mistake I think I have made. I was hoping this set up would serve all my power...
Hey! Thanks for checking in, so I think you're correct, it's 250V. I've included a screenshot. I have bought the fuses and busbars that you recommended but haven't hooked anything up yet. I had some other guy get on here and waste a bunch of my time saying he was going to help only to not...
Thank you. This is really helpful. Is this called balancing? I've been doing a bunch of research today and with the panels I have, (315w/33vmp/9.5amp six total) and the 4 SOK batteries, I probably am better off only using one of the Growatts instead of linking them as the amount of panels...
Ok. Thank you Hedges. yeah, they're all going to be in the sun pretty equally. No real shade around except in the early morning as the sun gets over some trees, but after 10 till about 6pm they'll all be getting equal sun.
So I watched the video of Will's where he hooks up a Growatt to a signature solar battery, 48V and I foolishly went out and bought two of each thinking I could put this together. I realize that when Will says something is easy, it's easy for him or if you have the exact gear he has and are...
