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...

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...

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...

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...

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...

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...

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 in the process of planning out how to get pv wire from inverters to the solar arrays. The distance is 450 feet. I have concluded with advice from others that I need to use 8AWG (8 guage), pv rated wire. I will have 16 total wires, each 8awg, going thru the conduit. If I use schedule 40...

I am in the planning stages of a new system install, and need some guidance from those of you with experience. This is a completely Off Grid install. No electric on site. It is my understanding that prior to putting batteries in the rack and connecting them all to the bus bar that i am...

I am trying to understand if fusing is required between multiple parallel racks of batteries: My hypothetical: If I have, for example, FOUR (4) Full, 48V EG4 LL (V2), battery racks. Each rack to be connected to a common bus bar, then bus bar connected to multiple inverters (in this case 18kPV...

I have zero understanding about T Fuses, but noticed Will had one in his review of the 18kPV. I am intending to have 2 x 18kPV inverters in parallel, and connected to a rack of 6 EG4 LL V2 batteries. Please explain how to calculate the appropriate size of T class fuse, that needs to be between...

EG4 - 18kPV - String Calculations Using Canadian Solar 385W Panels This is my first time attempting to calculate PV String series to determine maximum panels i can safely put in a string and not exceed max voltage of the MPPT input. Many of my assumptions may be incorrect, and I am...

In searching for info on the new EG4 18kPV I ran across this review based on the specifications:

https://enteligent.com/solar-fast-ev-charger Does anyone have any info or know of a review of this EV Fast Charger? It appears that it can Fast Charge an EV from a Battery Bank. I think this will be the key to greater interest in diy solar and ev adoption. Any thoughts?

I am seeking any information from knowledge or experience, about the FREEWIRE DC Fast Charging machine? And any info on supplying one of these FREEWIRE DC Chargers via an Off c Grid Hybrid Solar power system? Thx

I have been searching for a product, or doy project, that can function similar to the emporia ac power monitor, such that you can just put a split clamp around each solar panel output wire and remotely monitor the output of each solar panel. What I have learned so far, is that the Emporia type...

IDEA for Consideration and Requesting your Feedback on this concept: Instead of have a flat surface where all solar panels are on the same surface plane, What if we were to create a Top Row in Series, and Angled to Maximize Winter Sun Angle, then a Bottom Row in Series, and Angled to...

Is it possible to find Open Source Firmware, for various inverters? Such that, those who can write code, could evolve the firmware more quickly and efficiently, for everyone to use? For example: If you had a MegaRevo, Deye, SunSynk, EG4 or other Voltronic oem clone, the open source developers...

PLEASE ADVISE What is a correct way to wire the AC output side from each of Four (4) or more 6500EX inverters, into an AC Combiner Breaker Panel, then from that panel out to a Critical Loads Breaker Panel, so that the correct wires from each inverter are on the Correct Leg in the...

Request for Ideas: Could those of you with a greater depth of knowledge, design a Level 3 480V Power source, so that it could be used to quick charge an EV, using existing off the shelf components, hybrid inverters, etc??? Possibly two 240V Inverters pulling power from batteries, each inverter...

I am working on designing a new system using the new eg4 6000 split phase inverters along with the eg4 rack battery system. Here are a few of my questions, if anyone could please advise your recommendations: 1) It is my understanding that you can only have a max of 16 batteries on a single...

Disclaimer, I am a newb: If wiring multiple stacked parallel inverters to the AC Breaker Panel, do all of the L1, N, L2 connections get landed to the same main incoming breaker for the panel? Are there any special protections to make sure that the inverters do not over power back into the...

I am a newby to solar, and had intended to buy bigbattery kong for my design, why the negative feedback on bigbattery? I watched a lot of videos and they seem very professional. Just seeking clarification, to guide my decision. thx

Can anyone offer any Feedback on Quality and Reliability of Liniotech Inverter, and any info on Customer Service? https://liniotech.com/liniotech-split-phase-max-15kva-pv

I am very new and request guidance from more experienced solar system builders: If you design a system with multiple paralleled inverters (half of them out of phase), should the battery systems (racked or otherwise) be on a common buss and then connected to all inverters from the single bussed...

I am new to using this forum, but seeking advice on Hybrid Solar Inverters: I have looked at Rich Solar, MPP Solar, Sungold Power, and they all look similar. Are these each oems of one another? How do they compare with each other and with Growatt? Thank you

I am looking for rackable 48V battery systems, my first choices are currently EG4 Gyll, Seplos, more so because I lack knowledge. Are there any good reviews or recommendations of battery systems, that compare quality, reliability, cost, warranty, etc.??? And what other brands should I be...

I am extremely new (to solar and to using a forum), and this is my first question, so I apologize for my mistakes in advance: My Question: I am trying to educate myself on as many brands of inverters and models within brands, so that I can make an informed investment. I am finding it hard to...
