First, I want to thank Will for his dedication to testing, reviewing, and making information readily available to us.

I have wanted to start a solar setup since buying property in East Texas, but 3 years ago, things were not nearly as refined as they are today, and waiting 4 months for cells, and building my own packs and having 15 different electronic control boxes from various venders just did not seem to make sense at the time. With the recent products released, and the "relatively" affordable costs of the server batteries, I have decided to go forward with starting my system.

My initial goal is not to be completely self reliant, but I do want to be able to not have my power go out once every month when the weather is angry here. As I work from home, and am pretty rural, having the power go out not only makes working very hard, but it also kills my cell service, and that makes everything kind of difficult.

I went in to SS, as they are only an hour away from me, just to ask some questions, and maybe pick up either a battery, or an inverter, but mainly to ask a few questions. In the end, my setup will be solar for the main house, 2 remote trailers as *guest houses*, and a 40x40 shop with pretty heavy requirements for equipment. My initial goal is to just cut down on a portion of power consumption for the main house and add on as I can afford.

My initial setup will be as follows:

EG4 6000EK * split phase 6k inverter*
EG4 EG4 life power 48v server rack batteries x2
Canadian Solar 355v panels x10 (9 for service, 1 as a spare)
SS 6 bay battery rack

I will be running this system configured in the solar/battery/grid configuration. Having 2 mini splits, and currently having electric stove/dryer/water heater, I think this will be the best way to start. I will be changing to gas stove, tankless hot water heater, and dryer as some of the other projects get done. But this is just to get me where for the time being, when I lose power from a storm, or from scheduled maint, I am still able to work, run AC/Heat, and continue to function.

The goal is to purchase batteries in pairs as I am able to afford them, and look for deals on panels. I will basically be covering the entire roof of the 40x40 building, and add inverters *guessing I will buy 2 or 4 EG4 6500ex Single phase inverters to setup the shop and branch off to the rest of the property as I can afford.

I think between having Propane for heating/cooking needs, and a 24KW system with supporting batteries, I should be mostly self sufficient with about 20k investment and some hard work. I may also make both of the trailers their own independent systems as one is 50 amp single phase hook up, and the other is 30 amp single phase. I can get away with maybe going with the 3k inverters, one in each, a few panels, and smaller batteries outfitted where the original marine batteries live in those.

When I finally build my house *approx 1200sqft, it will be constructed with solar in mind, extensive insulation, and as much low voltage lighting/appliances as I can do.

I will document/vid every step of the way, and happily accept any input from all here. I hope to be an active member on this forum! Thank you all
 
Greetings fellow Texan.. You say split phase then mention single phase on the shop and then mention branching off to the property. Are you planning on running 240V only at the shop? Some of the EG4 units have to be in pairs to get split phase...however they now have one that is split phase in one unit. So, you can get one to start and then add on. Just thought I'd let you know. It looks like you mention this one..which is split phase. I think this is the way to go so you can start small.

 
That inverter will gobble 25% of your battery capacity just by being on.

The first 500W of your array is dedicated to feeding the inverter's idle power consumption.

Have you conducted an energy audit?
Good catch..they use a transformer for the split.

Built In Transformer for 120/240v AC
 
I don't think I caught anything. All of the cheap Voltronics made units have high idle consumption.
It seems higher than the MPP HF models will tested...no? The transformer (LF) ones idle higher. I guess what I was trying to point out is that LF versions ,regardless of maker, idle higher than their HF versions.

I haven't observed that. I've observed a very consistent 40-50W idle burn per 3000W of inverter power regardless if they have a large transformer or not.

I believe it was Will that did a video on a HF mpp and LF mpp of same output and the LF had a higher idle. Appreciate your input on this..I'd actually like to know more from people that have both. It would technically make since the transformer is also pulling a load in addition to the units other components as well.

Sorry if that was confusing, The shop is large and I still have a lot to figure out when expanding. I am starting the main house off as the only solar offset to begin with, and I am going to use the 6000ex split phase to start. The 6000ex from my understanding, can be chained up to 9 units. I figured this might be the way to start, as I only need one inverter, so the initial cost is about $1500 less as I do not need a pair.

What I am thinking, is the shop, I will be running pairs of the 6500 single phase inverters, *unless there in newer/better* but that could also change depending on how the 6000ex works out. SS stated they have only been selling this unit for about 2 weeks, and they do not really have any long term data on them, and I was unable to really locate any testing/reviews on youtube as it is so new.

I need to do a few different layout/planning diagrams, to figure out if it will be easier to cover the roof of the shop, and have power run to the house and the 2 trailers and shed, or, if it makes more sense to have both of the trailers be their own independent solar islands. As neither of those require 240v for any reason, I would be able to get a smaller single phase inverter, just a few panels up on the roof of the unit, and go that way.

All I know is, with how quick the prices are going up on the batteries right now, how much the price per KWH from my co-op electric company has gone up the last year coupled with the unreliable up times, it just makes sense to get started small to offset my monthly bills, and to ensure no power outages. And having the ability to easily upgrade as needed and I can afford, seems like a no brainer.

The other factor in starting out this way, is they have the 6000ex in stock, and I do not need to sit on the wait list, and hope that I can get 2x 6500's when they receive their order in October.

Hope that clarified.

Thanks for the input! I have not done an energy audit yet for a few reasons. 1, this was a shoot from the hip, to get my toes wet, so I do not procrastinate anymore. 2, I am not looking at going completely off grid right now, just getting started, and offset and have more reliable service. 3. New appliances, insulation, and some remodeling will be done to the current house *converting most large electric loads to propane*, 4. I will be building a new house ground up, and solar, extensive insulation, and low voltage will be a consideration from the get go.

I do plan on getting my clamp meter out, and measuring my loads on each line in the house, so I can make any changes in my main panel, to as equally balance the loads on both legs.

I have much more reading/learning to do on everything before I start the actual implementation, including the fun part of seeing the best way to separate the main panel vs running the solar. My 2 trains of thought are 1. Run "critical load circuits new" Where I would do all new wiring and a separate sub panel that feeds 1. Fridge, office, internet/network equip, cell booster, and leave the rest of the house wired as/is, or 2. *more likely* set up a sub panel near the install that feeds to a junction box where I will cut the main power in, divert it to the inverter, and tie the output into my main panel in the house there.

I have a lot of sketch work to do so I can determine the best place to mount everything, how much wiring I will need to be pulling from the main service in on the pole to the house, and such.

I am going with this setup to start with all at once for a few reasons, one, because I should be able to pick up everything I need this week to get started less racks for the panels, for about 7k, and it is in stock and getting a discount on everything for the *package price* saving several hundred dollars over just buying a part here and there as I can afford it.
