Has anyone else had this issue? I have 3 EG4 LL 48V batteries. They were reading -3c, 04c, and -3c. When I checked Solar Assistant, they read 39.2F, 41F, and 44.6F. Any thoughts on why the difference?? The SOC percentages on the batteries and Solar Assistant were the same and correct.

Initial info is what I sent to Signature Solar tech support Hello I have been using the chargeverter for a couple of months now. I have an Lv6548 inverter and 3 Eg4 LL 48v batteries and have Solar Assistant connected to monitor the entire system. Yesterday when turned on the chargeverter...

I finally got my EG4-LL v2 battery installed on my system and it seems to be working well. However, now my SOC's are extremely different across all 3 batteries. Here is a screen shot from Solar Assistant. Pack 1 is the v2 battery and packs 2 and 3 are v1 batteries. The SOC's did seem fairly...

I have one V2 EG4-LL battery and two of the V1's in parallel. How close should all 3 batteries be for the SOC's?? Currently the batter closest to the inverter (LV6548) is at 71 SOC. Next battery is at 76 SOC. Last battery is at 81 SOC. I know the first battery can be lower because it is...

Last spring I installed the EG4 Chargeverter 5000 on my system which consists of an LV6548 and 2 EG4-LL 48v 100a batteries. It worked fine the one time I used it in the spring, but now it doesn't want to charge. I have it hooked into my Honda 2200i generator using the 30amp plug. I've tried...

I just got off the phone with signature solar tech support who just wanted me to know that solar assistant has been shown to have issues with the eg4 batteries and burning out the BMS circuit boards. Has anyone else heard of this or had this issue happen to them? I did find the thread below...

Need some wisdom here. I've been getting conflicting information from Signature Solar. I have 2 of the EG4-LL 48v 100ah batteries v1 and considering adding a third one but can't find V1 batteries. Been told I have to upgrade my firmware in the 2 I have in order to add a V2 battery. Then...

I have reviewed most of the threads on this topic, but unable to find an answer. I have an LED shop light plugged in directly to the AC output and getting flickering every 1 to 1.5 seconds. Setup: 1 lv6548 2 EG4-LL 48v batteries 30 amp panel in cabin directly from the LV6548 Turned off...

Something weird has been happening lately. I have an LV6548 powering my cabin. I have a radio plugged in and keep getting a crackling noise in the speaker. It goes away as soon as I unplug it from the wall socket and run it on battery. So, I'm guessing it has something to do with the power...

Well as luck would have it, my first winter with my new 2 solar arrays showed that my sun calculations were slightly off. The second array gets most of the sun while the first array gets next to none due to my neighbor's trees and the angle of the sun. They both get plenty of sun in spring and...

I would like to thank everyone who has helped me over the last year or so and answered all of my questions. If not for Will's videos and website, I never would have been able to do this. I finally got my entire system working now. Far from perfect. Still have work to do. Especially with...

Just noticed that the RGB Led bar on my LV6548 is flashing. Any idea what is causing this? Almost looks like a certain pattern but hard to tell.

I have my solar setup slowly moving forward. So far, I have my LV6548 installed with 2 - EG4-LL Lithium Battery | 48V 100AH batteries. The solar panels aren’t up yet but will be working on them next. In the meantime, I’ve been charging the batteries using an external charger plugged into my...

Looking for a 12v converter from a 120v plug at the cabin to run my Sureflow water pump. Does anyone have one they like? Thanks!

I've been researching ways to ground mount my panels and came across this adjustable system. Brad came up with a unique and what seems to be great idea: https://youtu.be/gHZCTBCteW0 The ability to have panels adjust/move would help me a lot since my area is surrounded by woods that I don't...

Does anyone have a picture or description of how to use a 4/0 wire lug on the EG4 battery terminals? The lugs are too big to fit. Filing down the lugs is making them to thin. Not keen on putting a bus bar extension on the terminal unless I figure out a way to cover and protect it from shorting...

Looking to make sure I am wiring my LV6548 correctly. Will be totally off-grid. Will have a generator going into the AC input to the LV6548. AC output is going to go to a breaker panel next to the LV6548. The plan is to later add a second LV6548 for 240 volt to operate a well pump, but that will...

Has anyone been able to purchase solar panels from altE lately?? I just went to put my order in for my system and they are saying they will only sell to those that are purchasing an entire system from them!

I have an MPP LV6548 that I hope to get installed this spring at our off-grid cabin. After all of my battery debacles and other shipping issues, I want to try and get a jump on the panels. Looking for suggestions on which panels are working the best for you and your LV6548. I will most likely...

Having to redo my solar architecture. Have the MPP LV6548 and will be using 2 - EG4 48-volt 100 amp batteries. Looking at using a class T fuse, but unsure which size. 200 or 300?? Thoughts? Thanks

I have a small 12 volt setup to just run a small refrigerator and it has been working very well so far. I currently use the generator to charge the 12 volt 200 amp hour battery once every 3 or 4 days. I am using an inverter going from the 12 volt battery to the 120 side to the cabin. I also have...

Still waiting on my LiFePO4 batteries that will hopefully be here before winter, but not holding my breath. I just saw that Renogy is having a sale with the reopening of their Ebay store. I have the LV-6548 that is still in the box dying to be used and considering buying these panels since...

I am awaiting my LiFePO4 Lishen batteries and some other parts for my solar setup, which means I probably won't be able to get it setup and running until late summer at this point. I am planning on getting this Unique refrigerator...

I've been learning a great deal on here and would love to get input on my system schematic. This is for an off-grid cabin. I've already purchased the LV6548 and batteries. Let me know if off-base on anything or missing something. Thank you in advance for your help.

Just purchased my MPP LV6548 and have my LiFePO4 battery cells coming as well. Now, solar panels. Does anyone have any thoughts on these cells and if they will work with the MPP LV6548? Appreciate any thoughts or help you can provide. Reference Mission Prisim Trina Example...

Okay, I am new and have been learning a lot! But need some help on figuring out what solar panels to get for the MPP LV6548. I'll be using Lishen 32v 270 batteries to get up to the 48v and also have 2 honda generators for backup. Totally off-grid. I am getting confused on how to setup the...

I've been getting a lot of great help from people on this forum and I really appreciate it. Seems like the deeper I go into developing my system, the more confused I get. This will be for a fully off-grid 320 sqft cabin with 2 honda 2200i generators to charge batteries when needed and run an...

I was pretty much set on getting the LV6548, but have read some recent posts and have concerns about the maximum PV input at 18A. 6k is a little bit overkill for my off-grid cabin, but figured better to go bigger. I would probably only need 120 and not 240. My plan is to go 48V with Battle...

Planning stages for my solar system. Looking at a 48v system with AGM batteries. Originally was thinking of getting a DC refrigerator, but not sure if it is all that advantageous to run my 120 line and a separate DC line to the cabin just for a fridge. Will be using the cabin 4-5 weeks a...

Does anyone use a 12, 24, or 48 volt well pump in a shallow well? Our new property has a 25' well with a hand pump on it. Wondering if we can put an electric pump down the well to use for showers and toilet.

I've been looking at the MPP Solar LV6548 and 5048 for a while now and have been getting some great advice on the forum. However, I contacted MPP pre-sales with a couple of questions and here was their response: Both LV5048 and LV6548 are both very good options. The LV5048 is already split...

First off, thank you to everyone who posts on this site and for the people who have been helping me so far. I am learning a huge amount. So much that I might be getting myself confused lol. We have a 320 sq. ft. off-grid cabin with a Jayco 29' camper on site and would like to go solar. The...

We just purchased a 320 sqft off-grid cabin and plan on keeping our Jayco 29RLDS trailer on the site as well. I've been researching a lot on solar and would like to go that route, but the lack of available sun light might be an issue. I will know more on this once I am at the camp in the...
