Electrician to electrician consulting

DiverseEnergy

I am a licensed electrical contractor in Phoenix, AZ and have been receiving many calls lately from homeowners who want to go off grid.  I have installed 100's of grid tied systems over the years.  I was a crew lead for Solar City in 2012, lead for Solar Universe, started the solar department for PurSolar & Electric in Cottonwood (formerly Puriton Electric), and have been still installing systems for my own company since 2018.  But we all know how easy grid tied is.  And I'm certain that once I get it down, off grid will be just as easy.  But until I learn more about this, I am in need of someone who knows their s*^t and would be willing to help me with my projects.  Not physically, but just over the phone.  I am more than willing to pay you for your time and expertise, I'm certain you've earned it.  So if you're interested, please respond to this post, and we can figure out what compensation will look like.  Thank you in advance.

I would just recommend you using the store here. They will give you the support you would need as long as you are purchasing equipment through them. Using solar-electric.com (NAZ) would also limit having to install off brand equipment that has little support already. 

 One thing that won't work is installing equipment provided by a homeowner.  I know this from personal experience.

I appreciate the response, and I agree with you 100%.  And if I had the luxury of being able to pick and choose my jobs, I would do just that, but I don't.  So until that time I am stuck installing what the customer already has, and trying to troubleshoot some old systems.  So unfortunately, I need to continue to search for someone.

I think you would be better off hiring somebody who was well experienced in off-grid installations. Do some Hands-On with them. There'a a lot more involved in design and much more equipment than Grid tie as you mentioned. 
 With off-grid systems you've got to get it right. Where if you've got no power you get pissed off customers, unlike grid tie which Is just supplemental power and the grid will always be your dependable 24/7 power source.

Load calulations is one of the important functions of designing an off-grid system. If you use the search function, you will find a good number of posts about load calculations for lead acid battery bank sizing vs inverter sizing for loads. This would also be a primer to understanding C/rate of charge and disharge of batteries.

With the lower pricing now for Lithium iron phosphate its become a lot less complicated as the charge rates are much faster.

Some of the best education here came from BB, read his post carefully and follow the math he uses to make a valid point. Most of the needed knowledge for working with off grid systems can be found here. 

Here is a decent load calculator at NAZ in this link. I used it showing several customers what goes into sizing there system, they would buy the equipment from NAZ and I would help with the install.
