Thank you, I mistakenly thought each unit output was 200Amp because of breaker. That makes it much easier for me to wire. Still learning!!!

Will Prowse’s Blue Print for Parallel EG4 6000XP I watched Will Prowse’s video on paralleling TWO EG4 6000XP inverters. It was great info as usual. I need assistance on the folliwing: I am trying to parallel Two EG4 18kPV Inverters. Each can output 200Amps 240V. I need to combine both...

I am wanting to search for any brand Solar Generator, that offers the ability for the AC Outlets to turn on automatically, once the batteries have sufficient power stored. My issue: i do not know what this feature is called, such that i could search for Solar Generators with that capability...

https://watts247.com/product/dc-breaker-4p-125a-battery-disconnect/ i am still learning, so do not rely on my suggestion: but my understanding is that this breaker has 4 connections in and out, each capable of 125A. If you had a bus bar (comb style) to put on each side (in and out), you could...

Please explain this further.

Here is an idea for your company or any reseller in this niche: When people diy build computers there are web sites that have categories covering all of the major components. As you pick a component it has the data needed to determine compatibility with other component categories. I think one...

I am about to purchase 4 of these and waiting to see if there is an issue or if it is easily diagnosed dont want to spend the $$ if design issue or component issue thx

Any updates on this issue???

QUESTION OF THE DAY… Setup: 2 x 18kPV Inverters 60 385W Canadian Solar Panels wired as 6 strings of 10 panels each string Intent: To wire one string to each mppt (not using parallel ability of mppt 1 for now) intend to buy 20 more panels later to make use of mppt 1 parallel each mppt max is...

I currently have Two EG4 Battery Racks, each with 6 48V Batteries 100Ah of storage per battery, so 600Ah storage per rack. I don’t understand how to calculate the DC breaker size i would need to place on each rack. I understand that each individual battery has a breaker, but I want to be able...

Would like to know once you resolve. I am planning on purchasing these for my system.

Can you recommend a dc breaker, disconnect, etc that should be considered. thx

I would like to point out that this forum has been immensely valuable in helping me understand various considerations while designing a new system. I was a software developer back in the 1980s, and when we would design software, many of us would sit around a conference table and brainstorm...

This has been very informative, and much appreciated. Thank you for taking the time to help me understand this.

Thanks!

Main Service Panel - would be the same type panel as if you were getting power from the grid, but instead it will be getting power from the inverters (2x18kPV), which will be located in a small shed to isolate it from the main structure.

Grid is not available. I am using a small gas generator for temporary power until i get the big system installed.

When considering Neutral Ground Bonding in a Completely OFF GRID system… If instead of a an electric company grid transformer supplying electricity as the source of power, we now consider a completely OFF GRID solar outbuilding, as the originating source of power (some distance from...

Thank you for this excellent anslysis!

Completely off grid.

I originally thought that I would want a seasonal adjustment to get the max production all year long. Then I went to Solar Power Calculator at pvwatts.nrel.gov and started calculating different gains and losses throughout the year at various angles. My conclusions were: At my Latitude of...

This is a public service announcement… For those of you whom may be as stupid as me, i spent a bit of time trying to figure out How To Open the Door on our new EG4 Battery Rack Cabinet. Step 1 : Push the button that says PUSH the silver lock will pop out Now you...

Thank you for the additional feedback and considerations. I will weigh all of these factors into the design.

This is great info, and helps me understand how to connect to bus bar. Thank you

my initial thought on bus bar would be 36 batteries 100A each 3600 Amps but i feel like that is not correct

I have two (2) questions today: Q1) I am searching for online links to purchase a wireway wire trough to mount under up to four (4) EG4 18kPV inverters. a) not sure what terms to use in search b) have read other forum posts and located the hoffman trough, but not sure...

So I think, for this build (since it is my first), I will likely go with Four (4) of the 4 to 2 boxes from watts247. Even though i will only use 2 strings in 2 of the boxes and one string in 2 of the boxes. I may reduce that to Three boxes, but not sure if the Arrays will be in one row or...

I am installing Two (2) EG4 18kPV Inverters. I am going to put Three (3) Strings to each inverter. One string to each MPPT (MPPT 1,3,4) Not using MPPT 2 (which is paralleled internally to MPPT 1). Each string will have TEN (10) Canadian Solar all black 385W panels in Series, each panel is 43.9V...

I am thoroughly confused! But greatly appreciate the discussion, and differing points of view. I also want to be safe so no one can get hurt.

Follow up question: A few of you mentioned a ground wire in the conduit from array to inverters. 1) Should I have a ground wire in the array conduit? 2) If yes, what gauge, and what do i connect it to in the inverter area? thx

My apologies, I was focused on something else and did not explain why I wanted to be able to pull 18 wires. Two (2) 18kPV Inverters, Three (3) Strings to each inverter. But I am anticipating I may want to add another inverter and 3 more strings for the third inverter. 12 wires for existing...

I was thinking of having 2 more pairs in case I later want to use the ability of mppt 1 to have two parallel strings of identical size (i may gave to reduce to 9 in series to stay within specs have not calculated yet) but may never do it i need to add some experience to my youtube education

sorry, 3 strings per inverter 2 18kPV inverters 6 total strings
