So often I have had to keep my thought(s) to myself, especially when dealing with an electrically ignorant inspector. I just saw another post in here commenting on it, then thought, "I bet there are a few stories floating around"... After 40 years of electrical contracting I do have a few. The...
What I dislike about this forum
Well, can you tell that is a deliberate title to make you look further?
But, I should make it truthful, I would love to see a “Suggestion Box” for topics or whatever, that does not belong in a listed thread. So, I don't like that it does not have one. This said…...
I saw in one of the threads, perhaps pictures of off-grid, a really nice setup with lots of wiring in, what appeared to be, schedule 40 pvc for water. I did not comment, but I did think about it. I am out in California and just 5 years ago over 10,000 AAA homeowners in Placer County had their...
I have:
One 22kw backup genset feeding a 200 amp auto-transfer switch.
One SolarEdge7600H-US inverter with an associated PV array.
I would like to add a battery AND tie the generator to the Backup Interfface, BUT
The technical specs for the StorEdge Backup Interface state “Generator –...
I am an electrician and whether I should be posting in the beginner section, or a thread specific venue, is a quandary at times for me.
SunGold has been good at responding to emails with questions, I am sure I am testing their patience. I never asked about a warranty, so this is not a warranty...
This should probably be in the BEGINNER section…but this forum looks very specific. I am an electrician learning about PV systems, I have a client trying to become as off-grid as he can. He has a system with a small PV array feeding into four inverters: SunGold Power 6.5KW BluePower SP6548 SOLAR...
Electrician with negligible knowledge of PV systems…for now.

There were two SunGold Power older model SP6548 each providing 120VAC, together providing 240VAC to a small loadcenter...
We have:
Four SunGold Power SP6548 inverters
Sixteen LifePO4 300 ah batteries 4S4P
We intend to install these on each bank of four batteries between the bank and the bus:
Four Renogy 500A Battery Monitor with Shunt
Four HA02 battery equalizers
My question, please, what is a good way to...
It may be that if I read every thread, I will find the answer(s)...but maybe having them in one place will help others too?
16 Jita 12.8Vdc 300 Ah LifePO4, I think 4S4P (what is the difference 4S4P and 4P4S?)
Anyway...
four SunGold Power 6548, two as 2P1 and two as 2P2 @ 180 out.
There are...
Well, my roller coaster ride continues. First, just to head off the “never do that” stuff, it has already been done, I know better now, but it was not me to begin with. Also, since trying to help a friend AND joining this forum the 16 JITA 12.8vdc 300ah batteries arranged 4S4P will now have a...
Shouldn’t any control component with dinky little wires, attached to a battery, be fused?
We have all 16 LifePO4 batteries (4S4P) now connected to balancers, and it has made a huge difference. So, the Band-Aid for a poor way to do things seems to be helping immensely. We are going to install...
Can this really be a disconnect ( https://a.co/d/fuCknn6 ), operated under full load conditions – 300amps @ 60vdc? If it is not, but is merely an isolation device, it seems someone could get hurt using one as a disconnect. I complained about it to Amazon, but who knows where that stuff goes...
I ventured out into the other areas of this forum, it was jumping into the fast lane too quickly. I also know these “discussions” can branch out into “you should never have done it that way” and this is very often true, but, perhaps we can just stick with making what we have work as best as is...
I am taking a 2023 NEC code update. One of the updates is this:
"In the 2023 NEC®, a new definition of a PV String Circuit was added to Article 100. A PV string circuit includes PV source circuit conductors of one or more series-connected PV modules.
For years, common industry terminology for a...
PG&E offers a lot of free online classes relative to a variety of energy savings topics that include solar. They are given by industry "experts", designers, engineers, etc... I sure hope pasting the link is ok: https://pge.docebosaas.com/pages/19/my-home-page
