Tesla aka Solar City just finished up installing my 9.1 kW array of 28 (325 watt panels). To go with this they installed a Delta Solivia 7.6 TL Grid Tie inverter. Since the max AC out is 7600w I am wondering how this is going to work. I called Delta and they said this is called over sizing and...

Today I was observing my charging and I decided to measure the voltage on cells that were getting extremely hot. I am currently using a IMAX with 16 batteries. The charge is at 6amp which turns out to 375 mA per cell. In no way should a health cell get hot. So I pulled one of the burners and...

My days of overclocking and liquid cooling my PC is over, the powerwall project seems to be a more fruitful. I have since moved to dual hex core MACs for all my computer needs, fusion is awesome to run Windows 10 if you need it..... Anyhow, back to my issue... I just pulled my power supply from...

Greetings Everyone, I have already started collecting cells, of course everything is running extremely slow.... I have 2 OPUS and 1 IMAX. I originally thought of putting this in my basement but have since reconsidered that idea and will be putting the battery packs out in the garage which is...

Can someone recommend a auto cad conversion tool? I have created what I thought would be an acceptable image of PowerWall mount diagram including precise measurements and when I go to convert it using a only tool, it strips out the measurements and leaves on the graphics.... Slight useless. The...

Greetings Everyone, Would like to have a few more eyes review my work which is based off Pete's image. I have decided that I want to add some additional ventilation to the packs, I suspect I will create a main exhaust fan to slowly pull air over them. Kinda like Pete's soldering system. Also, I...

Being very new to this endeavor, I thought it would be interesting and perhaps helpful to share my experiences with you in hopes we can learn together. Let's start with my goal, it is to obtain as many quality 18650 cells as cheap as humanly possible. In my area, I have checked all the major...

Greetings All, I have decided to jump into the solar energy generation market and I have signed up with Solar City to get it done. Not sure why, but they were trying to get me to buy a 7.4kW system that was going to offer me 85/15 coverage. I was not having any of that so I had them go back to...

This link just popped up on my system, looks like Jehu has a special deal going with a vendor.... New LG cells.... Watch his video

Recently I discharged a cell and then charged it.... it took 1456mA @ 4.2 volts and held...... I set it aside because, I decided to run a refresh on it... Now it is reporting 1812mA which might make it a keeper.... I know I should sit on it for a week and measure.... but is it possible for a...

I am new to this rodeo, have been watching the youtube videos night and day.... sometimes in my sleep, although I find myself having to watch them again. Anyhow, I was wondering what the proper procedure would be for reclaimed cells? Should I do a full charge and then test or should I do a...

I recently has Solar City out to the house to size things up and give me some prices. I like the people they sent out and they were very knowledgeable. It looks like I am going to settle with a 9.1kW configuration and it will be grid tie. Apparently our local government does not allow SC to...
