Energy Storage, PV & NEC Workshop at the ASES Conference August 2021

• October 20th, 2021

This is an audio version of the workshop that Sean White taught at the ASES conference at the University of Colorado Boulder on August 6, 2021. To see a video version, go to www.solarSEAN.com for a link to Sean's YouTube channel or find some of this material in Sean's classes at www.HeatSpring.com/sean

 

You can also find most of the material form Sean's Intensive PV workshop at the ASES conference, which was covered in the last podcast listed on HeatSpring for 2 hours of free NABCEP CE credit at https://www.heatspring.com/courses/introduction-to-solar-pv-design-installation-and-code?aff_id=t3nlgw 

 

Here is the description of the workshop straight from the ASES.org website:

This workshop will be jam-packed with NEC insight and interpretation. Sean White teaches PV courses around the world and has authored many technical PV books. Solar Photovoltaic Basics 2nd Ed., Energy Storage Basics, Solar PV Engineering and Installation 2nd Ed., Solar PV Technical Sales and PV and the NEC 2nd Ed. Sean will fill you up with as much information as possible in the time given, while entertaining you. This year Sean will focus more on Energy Storage Systems (ESS) than he has in the past.

 

Did you know that the NEC allows us to backfeed your house with electric vehicles (EVs) and that it is just the EV manufacturers holding us back? Be ready for when EV manufacturers let us do what they already should have.

 

This course will count for NABCEP continuing education requirements in every category and will also count for prerequisites for NABCEP Certification.

 

This course will also include a $200 discount for Sean’s advanced online PV classes.

 

A printable color digital certificate included with course, along with .pdf files of the presentation.

 

Your instructor is based in the US and teaches classes internationally. His resume can be seen here www.maximumpowerpointtraining.com

ASES Solar 2021: Solar PV Intensive Workshop with Sean White

• October 6th, 2021
This podcast is a recording of a workshop Sean taught at the ASES Solar 2021 Conference at the University of Colorado Boulder on August 6, 2021.
 
This Solar PV Intensive Workshop was fast paced and covered a lot of information. This workshop was in a way covering the same material Sean covers in his Solar PV Boot Camps, which are often 40 hours long in a quick 1.5 hours. There are slides and if you want to see the video version, you will be able to see it at Sean's Youtube channel. Here is the Youtube link for this video.
 
Topics covered include, Energy Storage Systems (ESS), PV Markets

Backfeeding the grid Hawaiian Style with Customer Grid-Supply Plus, which is the future

• September 22nd, 2021

Hawaii has more solar PV per capita than any other state. Since PV is the least expensive energy in the world now, this concentration of PV will soon hit other states and Hawaii is paving the way with new policies that will be able to deal with this abundance of noontime energy. California, which has a lot more people and by for more solar than any other state is also dealing with this abundance.

 

In this podcast, we will discuss one of Hawaii’s policies put in place to deal with the possibility of producing more energy than the grid needs, but still letting people export to the grid. The policy we are covering is called Customer Grid Supply Plus (CGS+). Get ready for these new types of policies to come to you.

 

We will also discuss energy storage, and a student review of one of our free classes for 2 hours of NABCEP credit that I do with Bill Brooks where we sadly get accused of being "too funny".

Latitude’s Effect on Solar Resource, Cheap Electricity and PV, Battery Equalization and then Bill Brooks talks about the NFPA 855 Energy Storage Standard

• September 7th, 2021

In this podcast, Sean answers 3 questions and then we finish it off with some wise words from Bill Brooks where Bill and Sean discus the purpose of NFPA 855 Standard For The Installation Of Stationary Energy Storage Systems.

Net-Metering Sustainability, PV Wire Sizing and East vs. West Facing PV

• August 4th, 2021
In this podcast, Sean answers questions about net-metering sustainability, with examples from the most mature PV markets in the US, Hawaii and California and how energy storage solves problems when intermittent renewables are on the grid. 
 
There were some changes in the 2017 NEC, where the requirement to have a temperature adder with conduit in sunlight over a roof were removed, making wire sizing simpler, although wire sizing is arguably the most difficult part of designing a PV system.
 
Our last topic here has to do with the optimal way to face your PV, given the restrictions of having an east-west facing rooftop. As Jim Morrisoin says, "West is the best!"

Grounded vs. Ungrounded Inverters, Battery Combiner Boxes and Community Solar

• July 27th, 2021
In this podcast we once again cover questions from you and those like you by popular demand. We will get into the different terminology and how it changed in different versions of the NEC, when we talk about ungrounded, grounded and functionally grounded inverters. We talk about the correct terminology for combining batteries in parallel and differentiate between community solar and community choice aggregation among other things.

Q&A: NABCEP NEC adoption, Higher Power PV modules & Solar Manufacturers Going out of Business

• July 12th, 2021
In this podcast, we are going answer questions related to solar and energy storage. The first question is about NABCEP and how they are going about adopting the latest version of the NEC. The next question is about higher power PV modules and are they bigger and more dangerous to install. The last question is about how to deal with and what to do about the possibility of manufacturers going out of business.

New UL PV Listing 61730 replacing UL 1703 for making the test work around the world and UL 3741 listing for Rapid Shutdown (Hazard Control Systems) with Bill Brooks PE

• June 23rd, 2021
In this podcast we talk about the new UL standard for PV, which replaces UL 1703 for PV with UL 61730, which took place in December of 2020. You can still use UL 1703, just if you come out with a new module design, it needs to comply with UL 61730, which makes things easier, since it is the same test around the world, instead of having a different test for the US and Europe for instance.
 
We also talk about the new UL 3741 PV Hazard Control Standard, aka the Rapid Shutdown standard, which is another way of complying with 690.12 in the 2020 NEC, so you can perhaps have up to 3 modules in series after shutdown now. Mid Circuit Interrupters (MCI) on every third module maybe all you need for rapid shutdown as long as it is a UL 3741 listed solution. This is big news and a new way to deal with rapid shutdown. An MCI is likely to be a switch that does not do maximum power point tracking (MPPT), or you can have a dc-to-dc converter (optimizer) that does MPPT on a group of 3 PV modules.

International Fire Code (IFC) and Energy Storage Systems (ESS) with Bill Brooks

• June 17th, 2021

In this podcast we cover the requirements of the International Fire Code and Energy Storage Systems and sizes of these Energy Storage Systems in the International Fire Code. There are special size requirements as we will learn soon. We were primarily covering the 2018 IFC, the 2021 IFC does not come out yet as of this podcast and even when it does come out it doesn't mean that it’s get adopted right away in your state and so the different sizes of the Energy Storage Systems that we're going to talk about cover from larger than one- and two-family dwellings up to large utility scale systems. Can you get bigger than the utility scale not that I know about, but I'd be interested in your crazy comments? Did you know that ventilation is not required for valve regulated lead acid batteries? That's right ventilation is not required for valve regulated lead acid batteries and you know that now. And also, did you know that the International Fire Code does not apply when you were applying the IRC that's the International Residential Code? And that's for one- and two-family dwellings so the International Fire Code is not supposed to be implemented for one- and two-family dwellings! Look at all this learning that we can do.
