Hey guys, Wondering if anyone has any experience with these panels. There is a guy on here that posted about the 550w version, he seems to like them. 370W GSP6G60M (H) Also, i'm not familiar with the advantage of the number busbars (this panel has 9) or the Half-cut cells. I'll try to read...

Nice. Are these the batteries you paid $1230 plus $660 shipping?

I got a 16ch emporia hooked up. Excited to see my actual consumption after a month

No extra land, and the city limits me to 10kw of panels. Trying to stay out of the middle of the yard, stay in the sun. If I did tracking at all it would probably be single axis with a manual winter/ summer adjustment. I have a north/ south fence line that I could put a row of panels on a long...

Tracking takes up too much room! They block each other when you start moving them around. I think i'm just going to have to fix them in place. Also, i think it makes sense for me to set my panels at the summer angle (13.8 degrees) since i use more power in summer (Electric AC, Gas heat...for...

Just read a great article on bypass and blocking diodes. I'm still not fully grasping all the functional differences between bypass diodes and optimizers. I get that the diodes protect the panels and optimizers optimize output, just seems like the diodes are also optimizing output when they...

Such cool tech! I love it. I'm excited to get my hands on it. I've tried to read up on the mppt's but I couldn't find a good explanation. And I had no idea there were bypass diodes in the panels themselves. Has anyone tried to mount bifacials on the roof with a standoff bracket? If I could...

thought this was funny. I was talking to Dawnice guy about the bus bars being welding straight to the batteries and tried to explain why i prefer studs. I think he has no clue and is desperately trying to sell it to me anyway. lol

I wasn't planning on using optimizers(?) since i thought i didn't have any shading issues. if i were to put panels in the shade of the pole, wouldn't the whole string suffer? Or would the effect be negligible? Since open circuit voltage per 400w panel is 35-38vdc (based on the temp coefficient...

Is your friend on the forum? I'd like to hear his story first hand.

When do you expect to receive your batteries? Are you going to test capacity? Let me know please.

Good point. He also sent this pic. I don't see a qr code. At what point are the codes added? I'll confront the guy about the used cells, but I already know the response. Edit: his response, "we can only sell new cells, it's dangerous to sell used". I'll either buy from luyuan or ss. Thanks.

Wow, sounds like I need to negotiate a little more. You got those specifically from dawnice? Did you deal with Paul? Thanks

Anyone have any experience with Dawnice in China? "Paul" is offering a 15kwh battery with ddp to Georgia for $2400 total. 100A max discharge 10y warranty which really means nothing if no one vouches

getting set up in my town is either going to be super easy or a complete disaster. There are only 3 lines of instruction for distributed generation in the "contractors manual".

Maybe i found something finally to answer this question: "...distributed generation equipment must meet current UL1741 and IEEE1547 requirements." I see the EG4 18kpv meets both of these.

Yeah but I've heard there were imposters of Jenny wu, thought probably Amy wan too.

Is there an email address to contact Amy wan directly? I've already contacted her on alibaba, just want to be sure it's actually her. Doesn't have to be email i guess. Thanks

Hey guys, I have searched around a little bit and I can't find a straight answer on this. I'm talking to Amy wan with luyuan and she is wanting to sell me a 304Ah kit with seplos bms for $2400 shipped. I looked at the battery compatibility list for the 18kpv and didn't see seplos on there. Thanks

Can someone provide a resource for actual panel temperature prediction based on changing ambient conditions? I'm not seeing it. Maybe there's too many variables. Also, I was wondering what kind of gains can i expect from single axis tracking AND bifacial gain. I did some comparison on...

I believe i read that they didnt want panels under the wires in case their wires dropped to the ground, onto the panels. yes, the trees are gone. I had the panels divided into 12s and 13s in order to comply with the limits of the 18kpv. Also wanted to separate the 3 small arrays because i...

I also like this config. Pretty simple. I thought i had the perfect spot to put my panels but i forgot that there is a power pole right in the middle of it! So it would be casting a shadow and i cant put panels under any type of power lines to my knowledge. Even though wire isnt "cheap"...

12800kw/year vs 14300 according to pv watts for roof vs ground. Attached This is great stuff guys. Very helpful. Thanks so much

I don't have any sw facing roof sections. The second pic with the ground mounts hows the true orientation of the house.

ok. thank you guys for that info. it was very helpful. I have a couple more questions. Mounting: Just wanting confirmation of my reasoning and anything i mightve missed: 1. Roof: 45degree slope, SE facing with a relatively complex roof surface. i can fit about 30 panels on the best parts...

Good to know that that is an option but I think, as long as there are no issues I would just get another 18kpv. As I convert my gas powered heat and appliances to electric and buy electric vehicles (I have 4 adults and 4 kids in the house so potentiality 8 drivers eventually. Although the kids...

Is there any reason why I couldn't add panels batteries and inverters later if necessary? I know it's not great to mix old and new panels but I think i would just put them on a separate mppt.

I read through all their docs, I don't think so. Seems like all they care about is pv output. I found docan shenzen (Jennie wu?) They have a 15kwh battery kit for $2800 shipped from USA.

Yes, cut the cord. They absolutely will not allow me to be connected if i have more than 10kw of panels. I told them I could set it to zero export(?), he just just shook his head. After I get it all up and running I might add a couple stand alone panels and inverter just for the pool. It's...

ok. so i could keep it under 10kw and stay connected. July-sept we use 2800-3000kwh/mo, so those months i would only make about half the power i would need, but that is definitely a good option. If i set up the bifacial panels optimally, i could potentially get 11-12kw actual output. would...

Hey guys, I have been collecting info here and other places on solar components and sizing and i have an idea based on my consumption what i think is appropriate. Just want to hear from people here. My consumption is pretty high even though imo we are pretty conservative with the thermostats...

Update: Joyce from ecoreesun has panels in California for $95 each. $0.23/w plus shipping. 415w BF from exiom Inxeption has 370w single face panels for $0.17/w with shipping right now. I'm pretty new to all this but I was looking for bifacial because there is the potential for significantly...

Yes, you should be able to see at the bottom, the total price for inverters, batteries, panels with ddp shipping =$25k. I have multiple quotes, all around that price.

Here's one of the quotes but they're almost all around 25k. At this point I'm not excited about the megarevo inverter bc of all the problems I've read about. I would probably just pay for the 18kpv from signature. The cheapest quote for a 550w BF from jinko was $68.50. The cheapest r10klna was...
