I wanted to get your opinion on the 1 string. In the solar edge app this what I see. A single string of panels connected to the inverter. That is the basis of my one string comments. I guess this could be something in the app? Not brave enough to actually crack it open and start counting...

I paid in full at the time they turned on the system. There was nothing from the building permit dept or electric company. I think the reason the contract spells out the part numbers and configuration is because the solar company is giving that to the installers as a configuration / build...

100% what I expected to see in my graph, peak production at mid-day. I hit peak at 10 and in NY electric is currently .16 per kwh, soon to be .20 if the proposed rate hike goes into effect. I am likely losing a couple of dollars a day in production because they didn't install what I paid for.

I think I have everything I need at this point. I appreciate everyone's input. I will post after I get it resolved just to close the loop if anyone is interested. I think this should be a cautionary tale to anyone working with these solar companies. They did a great job designing and...

The contract has a hard arbitration clause and I am required to notify in writing. Also their remedy is to fix or replace any defects within 14 days according to the contract after being notified. Otherwise I can take it to arbitration. I am going to send them a registered letter tomorrow...

the contract calls for 32 - 400 watt panels. Those were installed. the contract calls for 2 SE7600H-US inverters. Those were not installed. The contract calls for 2 strings, only one was installed. the contract is very specific about part numbers and configuration. It was just not...

Maybe, but they charged me for the larger inverts and dual strings. They failed to refund anything on that part of the deal. Also forgot to mention that they were not installing the system I contracted for.

Mine bitcoin? not the best option but you can earn something back. Investment cost for used minors is pretty low right now. I used to have a moderately sized home setup that made money each month. Can't earn back with prices the way they are today so you have to buy the equipment used. You...

Just want to clarify, am I correct in all this? I am guessing it's cheaper to provide one slightly larger inverter and a single string vs. actually building out what I paid for? Isn't it better to have 2 strings with separate inverters for my 12.8 kW system? That configuration runs the...

Good point, but I just checked my design documents and contract. The contract specifies 2 - SE7600H-US inverters for my setup. That would allow up to 15,200 watts of power from my array to be processed. They put the wrong inverter in my system, not too many panels. I know not to expect 12.8...

so the inverter is undersized? the solar company designed the system.

thank you for all the feed back. I got caught up in the "ready, fire, aim". I appreciate the links to the configuration tools and I am going to do a complete redesign based on those tools. . thanks again.

**Update** Thank you all for the advice and consultation. I spent a bit of time arguing on the phone with the solar company. The sales person was not fully educated on solar and kept disagreeing that this would solve the issue but they agreed to install the 2 inverters per the contract. The...

Thank you for taking time to give feedback. I didn't know about mixing batteries. 1st lesson learned. I will remove the 100ah and replace it with a 200 to match and move to series wiring them for 24v. I appreciate the recommendation on Samlex inverter. My goal is to have this system...

I have a 12.8 kWH grid tie solar system on the roof currently. It doesn't provide any power in the event of power outage. I need to provide power for a few appliances via a stand alone solar setup. I would like to run them full time from solar / batteries unless the bank goes below a set...
