Awesome. No brainer. While I've not fully hooked up my system, the multimeter is showing full power from the panels and at that price, there's nothing to complain about.
I already have a Connecticut Electric EGS107501G2KIT ($155 on Ebay) which moves the circuits from the breaker box and comes with an outside generator plug input. The manual transfer box essentially jumps from the breaker box to itself and when there is no power from the grid, you plug your...
Shading is always going to be an issue for me since I'm placing the panels low to the ground in my back yard, lots of tall trees. I also don't want to have panels facing different directions visually.
Seems like the advice then is to keep the two 40Amp Rovers, run 3 panels in parallel to...
I already have four 12v 100Ah batteries, while I agree it would have been better to have two 24v 100Ah, at this point, I am not going to throw out what I have until I see in my system I have a problem, I'm almost $1000 into batteries.
I can fuse the two strings of panels, I read that my...
I built a system around an MPPT Hybrid solar inverter I bought from China - 4KW 24VDC solar inverter with charger - pure sine wave, split phase output: 120V 240 AC 60Hz, and will be connecting the Inverter to a 30 Amp Chicago Electric EGS107501G2KIT manual transfer switch box that I have my...
Sorry, my bad. Each battery is 100Ah.
Each panel is 8.5 amps, so 17amps each string / a 20amp fuse on each of the three strings.
The controller is integrated into the inverter, but it seems that as long as I'm adding fuses, why not just add the fourth? So, three 20amp fuses and one 125amp...
For placement of the bus bars, someone on this board drew out this sketch looking for confirmation. Is this how I should set up my four 12V 100Ah batteries to get 24V 100Ah?
I purchased the six used panels knowing they would most likely produce 80% of their rated capacity or so and I was fine with that since I paid $60/panel. I purchased two new Renology Rover 40 Amp MPPT controllers with the plan to connect 3 panels in series and run them to a Renology, then...
This is the current battery layout, along with your suggestion to run 1/0 between the batteries and the Bar, and then 4Awg from the bar to the inverter. I could use 1/0 if you think it will help from the bar to the inverter, I'd have to buy more wire. Is this what you were suggesting, and if...
I built a homebrew system around a Chinese split phase solar inverter and would appreciate someone taking a look and checking to see if I have any errors prior to powering it up. I know there are several ways to do this, but my goal has been to add a generator option into the mix and that sort...
Is this the key then? Make sure the outputs have 3 connections rather than just 2 since I think many Chinese writeups are not going to be clear regarding this?
Two seperate uses. The 125 Amp breaker is for the panels, the T Fuse is for the connection between the batteries, two 12v 100Ah, making 24v 100Ah, and the inverter.
This all began as an inexpensive project because I got my hands on 6 inexpensive, but powerful, panels. I can't change from 24v to 48v because the manufacturer already began the torodial transformer, for 24v.
I called MPPUSAsolar and spoke to a salesman, guy with a British accent. He was less than helpful, although nice enough, and was not interested in my needs or which of his systems would be best to meet my requirements. I did not get a warm fuzzy feeling buying from them and when I asked about...
That inverter is out of my price range, but thanks for clarifying my understanding regarding wattage/size. One of the inverters Will suggests, GIANDEL 24 Volt 2000W Pure Sine Wave Power Inverter, costs $369. That's where I am currently leaning, and anticipate purchasing an inverter later today.
Its so hard to read the Chinglish and decipher all the features on these ads. I'm going to take another look and see if one of the other units might be more obviously usable for my needs.
I keep coming back to this POWMR inverter:

I'm trying to figure out the number of batteries to purchase to make my new system operate. Currently, I have 6 panels running in a 2S3P setup (260W, 30.6V, 8.5A). I currently have two 12V 100MAh LiFePO4 batteries that I will combine to get 24V and was thinking I should grab another two...
The LV6548 ($1575) is double the price of the Growatt 3000TL LVM ($712) so I think I will go that direction and add a second 3000TL later once I get comfortable with the entire build and its operation.
That said, I will power a sub pannel off the main breaker connected to the 3000TL and just...
