Anything stand out as you are going to fail inspection? All the grid side AC stuff has been inspected and approved already, all the solar stuff needs to be inspected yet, will schedule final for next week.

I am setting up some ground mount panel arrays, how are you supposed to properly ground them, where do you run the ground connection from the panel frames to exactly? Thanks!

I am going to be setting up solar in my new home. I plan to run off solar/batteries and will still be connected to the grid in case no sun and batteries are dead. I also have a whole house generator that can be incorporated into this as well. These batteries are the first thing I have bought...

Anyone use KB Solar Panels? Are they any good? I am just starting my diy solar install and looking at panel options. I see they are made in the usa (parts sourced from china I presume) and they price seems okay at 225 for 450 watt panels. What are the most recommended panels to use, I plan...

Which are recommended panels to go with? I will be starting off with about 14kw of panels. I see KB solar has them that are made in the US, anyone have experience with those, the price seems good. They will be ground mounted if that makes a lot of difference. Thanks all

Hey all, I am new to solar so have a lot to learn. My wife and I are purchasing a new house in rural area with some land. We have lots of open space to put up a large solar array. To start I would like to tie into our current electricity provider but eventually add batteries and go off grid...

I am constantly getting EPS overload on my 3 6000XP inverters in parallel. I have read other threads about this and it seems to come down to not enough battery and/or the discharge current limit being set wrong. I have it set to 420 amps and I currently have 4 15 kwh 200 amp each battery...

I am still in the learning phase but so far I think this is the route I am taking. I want to set it up so I am on solar when there is sun, batteries when there is no sun and grid power when there is no sun and batteries are dead. I also have a whole house generator already I would like to...

If you have 8 48v battery packs all connected to bus bars, and from the bus bars you connect to your inverter, what controls which battery and how much load each battery gets? I will be using all 200 amp with 2 amp active balancer JK bms's on each battery pack, do the bms's control this? Does...

Doing a solar install, my understanding is everything needs labeling and plan order labels via pvlabels, so the conduit needs labeling as well or just the boxes/disconnects etc?

I am having 20 panels installed on the roof of my pole barn (I have the panels already, hiring someone to do the work), what are some recommended roof mount kits I should look into getting for this, it is a shingle roof. There will be 2 strings of 10 that will be go to one of my inverters (EG4...

Stainless bolts/nuts fine for use with 48v battery bus bars? Any recommendations?

I am putting up 3 adjustable angle ground mount arrays, each with 10 400 watt bifacial panels, I am in Michigan. I am putting the 3 all side by side to each other. I am wondering if it is beneficial to put one aiming more SE, center one straight south and the other one facing more SW? I will...

I am close to finishing my solar install (will schedule final inspection this week I am hoping). I still have to learn how to setup/configure the 3 eg4 6000xp's etc though once I get my green sticker. But I am wondering about monitoring the system. I know the 6000xp has some monitoring built...

I have occasional flicker when powered off solar/battery (but not when on grid) on my 3 eg4 6000xp inverters. I figured out one of my 3d printers ac heat bed causes flickering as it turns on and off rapidly to maintain temperature same with my electric kettle once it hits the set temperature...

Can I use thhn stranded copper wire for earth/ground and direct bury it? They bury bare copper wire when used as earth so I would think you could use it.. am I wrong?

I ran out of black PV wire, can I use red PV wire as the negative if I put black tape at the ends to signify that it is negative?

I have batteries and inverters (eg4 6000xp's, 3 of them to start with) but not sure which panels to go with. Are there big differences (besides wattage) between the ones sold for instance on current connected or signature solar? I was looking at 2 pallets of the Hyperion 400w bifacial panels...

I have 10 extra 400 watt (500 watt with bifacial) panels after installing my solar system a few months ago. I have 3 eg4 6000xp inverters in parallel and ~170 kwh of battery storage with 60 400 watt (500 watt with bifacial) panels but want to keep this system separate. I am thinking of getting...

Hey all, I want to add a 12000xp inverter and some more panels to it, I currently have 3 6000xp's in parallel and have ~170kwh of battery storage. Can I setup the 12000xp and some new panels to it and have it hooked up to that same battery bank the 6000xp's are connected to? It will have it's...

I am building 3 tilting ground arrays, each array has 4 6 x 6 posts set in 24" wide x 36" deep concrete in the ground. How long do I have to wait before I can build the frame off of them (made of pressure treated 2 x 6's)? Each array will hold 10 panels but mainly I want to get started on...

I have two separate strings, 10 panels each on my roof, looking for a disconnect for them, will this work? It says 2 poles in series and number of strings is 2, that mean the two strings will be wired in series together or will they be independent to each other (which is what I want)? Any...

I am building a ground mount for my solar panels in Michigan, does anyone know if the mount itself needs to pass inspection? I have the permits for the ground mount and the roof mount panels (separate permits) but I am unsure if they are going to be checking just the electrical for each or if...

I have several diy battery packs I have built in server rack cases with 200 amp jk bms's, they are 16 306ah eve lifep04 cells to make 48v packs. I am putting two batteries in parallel to the bus bars before going to the inverters. I am going to have them run through a class t fuse, how many...

I got my solar install all done and inspection passed a few weeks ago. So far everything is working well except having some trouble understanding the battery relationship with the 6000XP inverters. I have 3 inverters in parallel and 4 batteries (total of 60 kWh of storage) in parallel with JK...

I want to put a small transfer switch to switch from grid ac or solar ac to the mini split in my solar shed, does something like this exist, a small ~15 amp transfer switch?

First year with solar and just had first snow storm. The snow is sticking to the panels like a glue trap and even brushing them off it does not want to slide/come off easily. For next year I want to wash and put some rain-x or something on them, anyone else have any better suggestions to help...

I am building some 16 cel battery packs and need a bms for them, are these a good option? I will be using Schneider inverters. https://batteryhookup.com/products/7s-21s-24v-75v-300a-lithium-ion-bms?variant=43085312884898

I am having a contractor install 20 panels on the roof of my pole barn, they are Talesun TP7G54M 400 watt (up to 500 watt) bifacial panels purchased from signaturesolar. I will have 2 rows of 10 panels each, each row wired in series, so two strings of 10 panels in each. The data sheet says the...

I am looking to hire someone in central Michigan area to install 20 panels on the roof of my pole barn which has 60 degree roof. The mounts are already installed just need the panels themselves installed. Already have permit, ready to go asap, get in touch please!

Does anyone have an example of what a solar plan looks like. I am about to get permits for my solar install and they require a solar plan, I am not sure what this is supposed to look like.

I have 4 batteries I just built on my solar install. One of them is not cooperating and I don't understand what it is doing exactly. It shows charge as off but it is on, the other 4 batteries appear to be working properly. I am new to all this so still learning. Here are screen shots, it...

How do I determine the spacing between ground mount arrays to avoid shading? I am located in Michigan, 85.07, 42.98. I have looked at calculators but I am not sure how to read/interpret them. Any help would be appreciated!

I just had the inspector out here for an inspection of my solar install (not final the final inspection). He said starting earlier this year Michigan requires a decommission plan for your batteries. He said I am the first person this year he has had to deal with this himself. Anyone familiar...

How do I figure out how far the edge of the panels will be off the ground with a given height post, angle the panels will be at and the total height of the array? I need to figure out how tall to cut off the posts that are in the ground, I want to have about 1.5-2' off the ground at the bottom...

My diy install is almost done pending final inspection. I am running 3 6000xp's in parallel and currently have 4 lifep04 diy batteries with jk bms. What charge voltage should I set in the inverter? Also will the 6000XP communicate with the JK BMS? I have all the bms's in parallel and...

I am looking to hire someone that can consult with for a fairly large residential solar install. I already have the panels (72 panels), 3 inverters and diy batteries and plan to do the majority of the install myself but some of it I want to hire out. I would like to hire someone to help with...

Anyone know if the 6000xp and 12000xp can be used with each other at all?

Does it matter if you mount your panels horizontal over vertically, is there an effect on their efficiency?

Question for those how have ordered from Gobel Power. I ordered 32 cells (Eve MB30) and 2 Gobel Power diy cases from Gobel. I chatted with "Ellie" on their website for a few days about what I wanted and to confirm the Gobel Power case came with the new JK BMS or not and so on (which it does...

I have a roof top junction box, I need to have bare pv wires enter the junction box, how to create water tight seal.. or is there a way to have them enter conduit with bare wires that will create a water tight seal then go into the junction box?

Hey all, I have 9 48v battery packs (with the new jk bms on each one) for my 3 eg4 6000xp inverters. How do I hook these up to the inverters (new system and learning, starting the install process now). Do I run them to bus bars, a negative and positive and from there to each inverter? Is this...

Hey all, I have a new solar system I put in, I am running 3 EG4 6000XP's in parallel. I have the grid connected, 24k watts of solar panels and over 100 kwh of storage. I am running the latest firmware. The system has been up for a few months and things were fine until the past few weeks, I am...

I had my eye on the EG4 18K inverter. I am looking for a solution to run panels, batteries, grid and generator. So it will auto switch from solar, batteries and to grid if the batteries get too low. I have a whole house generator right now that I would like to implement somehow as well to...

For roof mount panels, I know none of the wires can touch the roof (shingles), so is the proper way to do it would be to put an electrical box on the roof, run all the wires into that box and then through conduit to the disconnect, is this the way to do it so it passes inspection?
