Hey I just wanted to share my setup. I have posted my plans on here, received critical feedback and made corrections based on that. Thank you all so much for helping. I made this overview video I figured you all would enjoy. Feedback welcome. I would rather know if I have done something wrong...

I am in-flight with building a 50kw solar system to take my house completely off the grid. (Or at least turn the power company into my backup source of energy). I plan to update this thread and post will all of the build videos. I figured I would start a thread here to talk about it, but I am...

It feels awesome to remove the power company as a dependency from your life doesn't it. Congratulations!

Well I have a youtube video I put together as a demo. I only have the neutral leg disconnect circuit together at the moment. The video is still processing, but here is the link. This is a prototype and not even close to being ready for production. Please heed this warning. I think this...

Here is my final revision of the neutral protection side of this chart. I hope you all find it useful. The chart is open for discussion and rejections. I am also in process of making a build video so you can see how its put together in the real world.

I think we stop at a Full BOM and a working circuit that keeps peoples houses from burning down. The requirements for that are pretty simple IMO. If the neutral leg fails, turn off the things. If the utility power is being passed through, don't bond the neutral leg to the ground in the...

Here is the overview for my RV project. I wanted to get the generator away from where I sleep, and my wife has standards - so A/C is a must have. I built this system with the idea that I could run one A/C and my fridge overnight with no generator noises.

I am always interested to see people saying that this should be more simple than it is, however I see no diagrams, videos or parts lists. Not to say this can't be made simpler - I am sure it can. The most basic understanding has to be we are just a bunch of amateurs and the work is being done...

I know @Will Prowse already did an F150 video quite some time ago. I think there have been some updates since then (hopefully). I bought one a few weeks ago and I wanted to share my setup. I am using an MPP-8048 and 11.4kw autotransformer (completely disconnected from grid) to function as an...

High load peak of summer was 4500kwh a month when I started this project. During a cold snap in February of 22(I think), I hit 5000 kwh. It was at that point I knew I needed to do something, anything to make this house more sustainable. That number is just crazy. I had old R22 based units for...

I am very happy so far with my units. I even wired in a circuit level transfer switch to my shop and I am testing out how well that works. After a 30-60 day test period, if all is well I will be hooking the same system up for the rest of my house. I have to pretty much rebuild my whole system...

Here is the build video. I shot this a couple different times and I have found I suck at making good quality videos. @rfbuehler Yea, that is on the docket next. I was focused on getting a reliable system that will shut down in the event the neutral is lost. Next up is over temperature...

I just wanted to share my experience with everyone in hopes they will avoid using sellers who engage in misleading business practices. The story starts on the 28th of Dec 2022. I ordered two EEL 48V 16S Server Rack Battery DIY Unit BOX Stackable Type battery cases. I found these units in the...

If there is an EMP, energy is the last thing people in the blast radius need to worry about. I would worry more about the next rocket that is already inbound hot.

Just for anyone else that happens to search this string and land on this page. The issue was battery monitor improperly flashed the BMS and the firmware cannot boot. To fix this, I hooked up my BMS to a benchtop power supply, opened up battery monitor on the firmware flashing screen, set the...

Here is the spec sheet I will reference from - https://signaturesolar.com/content/documents/GROWATT/1519004-specs.pdf 7000w Solar Input Maximum Total 150VDC I don't know anything about your panels, so you need to do this math based on what the labels say. Lets use a value of 48v's per panel...

I couldn't have gotten here without this community. No doubts at all about that.

For what it’s worth once we get the OP’s question worked out, I planned to also show how to do this with a genset input on the GW5KES and tie back to the main panel with a simple interlock. I also wanted to show people how to setup this system as an SDS so it could be used as a backup (or...

Not to totally derail things, but have you seen this before? It does completely solve the ground / neutral bonding problem in a UL listed way. Turns the solar system into a full SDS, and may be more inline with what an inspection might be looking for. Portable Gensets aren’t UL listed that I...

Ok, here is a video to show what the SGP 12KW UL units do. Neutral and Ground are surely not bonded when they are turned off and disconnected. IDK why you would think there would be a 60v difference in potential between ground and neutral when unbonded - but when the difference is millivolts or...

There is a 2+ volt difference when on battery power. If they were bonded, the difference would be zero or near zero. (in the milli volt spectrum) There is no specification for voltage potential differences when they are unbonded, but there surely is some reasonable expectation when they are. I...

Here are the next two videos in the series.

I see there have been a couple of questions about using the chargeverter in different ways. Can I charge while the inveter is discharging? Well if you had a non-all in one system - this is how they work. A solar charge controller would be charging the battery at the same time an inverter is...

Oh it works just fine.

Oh I didn't give up on them, they are still in the shop. That system has been in production for 6 months with no issues or hiccups. This system is to power the house. I am going offgrid, bite by bite.

I am accounting for the system degrading over time. I also am planning for the coming migration to all electric cars/trucks. So will all that power be used up front... No, but it will be in time. With such a complex large system, I want to just get the energy needs of today and tomorrow baked...

Episode 2 is posted in the OP. Please let me know what everyone thinks of the shorter video format. I have been putting together longer videos, but it seems that very few actually watch more than 2 minutes. I just want to make the content people want to see, the way they want to see it: so...

Strange. My Chargeveters ramp up the power, they don't just instantly go to 100 amps. Maybe the model I have has the requested feature of the OP. I use mine for a "zero transfer time" setup, where I am always on battery and the Chargeveter is started via the dry contacts mean for generator Start...

I use a SE facing vertically mounted set of panels. Here is what I am getting from them. There will be 6 more panels mounted beside this array for battery charging only. I would go all the way up with 8 panels, but I can't find anyone to help me get the job done.

I absolutely need every single one of them
