Thanks both of you! So if my 2nd inverter is UL1741 compliant then it will not be an issue with backfeeding too much energy to the skybox as BentlyJ mentioned in his previous post? My shop loads will not be heavy or consistent most of the time. Although I am toying with the idea of heating...

Ok. That's what I was thinking. I just want to be sure I wasn't creating some sort of artificial "grid" by having two grid tie inverters. After reading some replies and thinking more about it, I think I understand how it would work. In my setup, the 2nd inverter will be downstream of the...

I currently have an Outback Skybox with around 5kw of panels. It is working great, but it is about at its limit as far as PV input. I am thinking of installing a second inverter out in my shop with another 3 or 4kw of panels that I picked up for a good deal. Are there problems with this...

Been using the panels for a couple months. but May was the first full month of net metering use. So we used about 79kwh of energy. , Energy usage was around $9, My bill was $55. We get to pay $40 just for the privilege of being Coop members. And another $7 security light fee. I think our...

I am in OK and I didn't negotiate the freight, but they just offered that price when I inquired. But yeah on their website the same 20 panels was going to cost about $375 for freight so they gave me a better deal. Just call them or contact through ebay. I saved about $10 per panel by...

Be happy to help. I have limited experience but have setup my skybox with a ground mount 6kw array pretty much by myself. Of course I did have the help of forum members here and over at Outback. The hardest part of my whole install was the ground mount system. I used unirac C pile and would...

I went ahead and ordered 20 of their 250's, probably similar to what I saw in that video. I made an offer for $700 for 20 of them and they took it. $275 freight to my residence. Not too bad, 5kw for $1000. About 1/3 of what I paid for my brand new panels for the 6kw array I setup for the...

I've been looking on their site. I want to add some AC coupled panels to my shop roof to feed into my skybox inverter. What about their T series 290W? They have a similar description but say for off grid use, I guess because the labels are missing. But that won't matter to me.

Well I installed the battery pack. BMS seemed to be bad (other post about that), so I just set the inverter to net metering with backup and hooked the battery directly up to the inverter w/o a BMS for now, until I get a replacement. I did take some advice and turn down the absorb voltage on...

Good plan! (On the beverage) On waking it up, I don’t know how to force skybox to charge and I don’t know why the bms would go to zero upon being connected to the inverter. Something is happening in there to make the bms disconnect or whatever it’s doing. After flipping the inverter break...

Well I suspect the bms is definitely bad. On top of the 49.1v reading at L-, when I turned on the battery breaker on my inverter the voltage (between b+ and L-) goes to zero. Or around -1.5v. But When i check the voltage between the pos and Neg post of the actual battery bank and it’s still...

Oh it’s just laying there so far. I’m not sure how to permanent mount it. I’ll probably just use some command strips or something. The sensor cables aren’t long enough to mount on the outside of the box. Is that what you mean I could extend? Or the p- cable? That one was pre crimped and I’m...

well I might have found an answer. There is a really lame video showing some instructions and it seems you have to either begin with charging the battery, or have some separate activation device that plugs into the "light" port on the daly. I just wasn't sure about the 49.1 vs 53v...

I started another post in the general forum, but turned into a BMS specific question.. I have my Daly 16s smart 80A 48v all connected and have manually checked voltages on every sensor via the back of the plug, seems all good, starting at 3.32 going up 3.32 at a time up to 53.12. I followed...

. I just realized there is a separate place for bms discussion. I may start one there since this is more of a bms question at this point. I did get mine connected. The only thing that concerns me is the voltage out of the p- is only showing 49.1 and the voltage of the pack is 53.something. Is...

Yeah, I didn't connect my plug to the BMS yet. I've only so far wired the individual sensor wires to the terminals. I think the instructions did say to not connect the plug while connecting sensor wires. But that's a good point to make sure I keep it unplugged while putting the B- on because...

Ok, so I found another instruction sheet online. It is written different that the little scrap of paper they sent with my BMS. It is more clear that the first red thin wire goes onto the B1+ terminal. My instructions were not written that way if I am remembering correctly. It said to connect...

Maybe that is how I did it, I can't remember and my pic has the plug covered up. I will have to read the instructions again. I thought I read that the first red wire goes to the "total" positive terminal, which I took to mean the 48v (54v) output terminal.

No worries. I actually got the bms yesterday and started connecting it. The instructions are probably from google translate so they are a bit hard to follow if you've never done it. But I think I got the idea. I think after connecting all the sensors in the right order, connect B- to the...

Ok. I'm sure thankful for you guys on these forums! I had gone ahead and ordered a daly 80 amp for this pack. Of course after reading a bit more and a reply over on the other forum it seems I shouldn't mix the 100ah and the 280ah planned bank. So I'll likely be selling this whole 100ah bank...

Not really. Except batteries. my panels all shipped quick. Inverter shipped quick too. Racking took a while to sort out but that was supplier issues not manufacturing.

I have a bank of 100ah ready to go, other than the BMS. have just a few questions. Not much experience using these batteries so I'm asking here first. I got my bank from a local guy. He resells from his Chinese supplier. Tests and balances them before sending me the complete pack ready to...

So in the winter we use very little electric. Maybe less than 10-20kwh/day, because I heat with wood and geothermal and also have propane floor heat, which expensive and temporary until I figure out a way to heat my floor with solar or geo. Anyway, I did start using the net metering. It is...

My power company requires me to add them to my liability policy as an additional insured. I know this is common for net metering agreements. But my State Farm agent hasn’t ever done this and is having trouble figuring this one out. He says his underwriter contact has told him they can’t add my...

Well after all my price & supplier research I didn't order from any of them. I ended up using the local fellow who offered to broker the batteries for me for basically a $100 fee. He orders from the same company all the time and normally sells locally or on ebay as I understand. I had told...

Yeah tracking systems are pricey. I’d probably design my own. They look simple but probably aren’t! Another drawback of our net metering plans is that our credits expire month to month. And they don’t pay us for our over production. It would be nice to set up something that would defer the...

We do have net metering available. I just haven’t signed up for it yet. I am working with the poco engineer now. They seem to have gotten more friendly to solar. We don’t have any variable rates. Our rates are fairly cheap around 12 cents. But will only have about $5k in my setup after tax...

Yeah they do have their own posts. 13’ long C piles. It is a turnkey mounting solution. A lot of work to install. When I ordered them I figured I’d just hand dig a 12” post hole and set them in 3’ of concrete. Nope! Either have to be pounded 6’ down with a pile driver or set in 6’ deep 24”...

hopefully these pre engineered unirac systems are strong enough. I followed the install requirements and then some. I used about twice as much concrete and rebar as they spec. Definitely will be adding at least 2 more panels. And with 1 more bay I could add another 8 for about $200 in extra...

Well I managed to clear out most of that row of trees. I left one large tree for now. I’ll try to see what it’s doing to energy production as I get done more history But I did notice about twice the production the next day during the 8 am hour. Well twice the peak power anyway since I don’t...

Well the skybox install is coming along good. I turned it on about a week or so ago after I finally got the last of my mounting hardware from renvu (what a mess they are). Anyway, I’ve got my 5.3 kw of panels producing on the skybox using a no export mode until I hopefully get an agreement going...

Yes qishou is who I would order from if I ordered myself. Her name is Amy also. She seemed like the most honest one to me. But there is also a guy who offered to broker them for me and he uses the same person for all his stuff so he trusts them. Sells a lot on eBay and locally. I’ll likely go...

Alithor is another one that some on here have ordered from, and Mushang. although they didn't get super good reviews..

Yeah, that's why I am seeking feedback here. Many have good feedback scores on alibaba, for what that's worth. and they take credit cards.

yes, I am hoping for that too. I am on his list but he is very busy. Hoping to find a place to buy at least 16 on alibaba. I would take up to 48 eventually. I know a lot of people on here have done it through China on their own, I did used to buy and resell a lot from China so I am fairly...
