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...
