look up your exact model and read the manual did you look up your model and see what its actual LRA is? how and where are you measuring this? if we still assume your batteries can do 400a, thats 400a * 12.8v = 5,120w 5,120w / 120v = 42a 42a * 0.80 inverter efficiency = 34a so you possibly...

I have 2x EG4 6500. Split phase for 240v Been using them since the beginning of this year. Completely off-grid. One inverter shows ~400kw in ~200kw out. The other shows ~300kw in ~100kw out. On a sunny day I’ll run them kinda hard. The most being 4.5kw Solar going into one of them, while...

Right off the bat, one of these companies is talking about heating to 300-500C. That’s 500-900F. So sounds like you can pump a lot of heat into a small space. Here is their website. https://polarnightenergy.fi/technology...

If they do become a trash problem at some point, people will probably be giving them away for free. Even if you have trash pickup by the town, you usually need to pay for oversized items. I imagine at that point people will ignore the solar part and find uses for them as just "panels"

Thanks so much @BentleyJ ! I could have sworn the 6500 did this, but after re-reading through the settings, I didnt see it. I thought I was confusing it with the 6000. I forgot the 6500 has a different way to program this thats not in the usual setting manual. Im completely off grid with my...

maybe this one is closer to yours...

I still haven’t updated my firmware, so I do have the same issue but it hasn’t really mattered with the nice weather and long days. I have an older model (pre Nov 22) (black terminals) and that is the one that works fine. New model (post Nov 22) (grey terminals) is the one with the issues. I...

I ment with PV and Batteries in Standby mode, but it sounds like no matter what the inverter thinks its overheating

Strange on Teslas website it says the normal powerwall has 10KW peak. But the spec sheet says 5kw continuous power. 7kw peak (for 10s). Powerwall + says 7kw continuous 10kw peak. All those are for a no-sun condition. Apparently it can do a lot more if there is sun available. Also powerwall...

By “fix itself” I meant, increase the voltage property. If you are pulling 3.5Kw then you must be at a higher voltage than 100v. Otherwise you would be pulling crazy amps. But do you have to “reset” it to get it to pull this much in full sun? Or will it start pulling +3KW on its own? Good to...

LFPs can handle sitting at near 100% a lot better than other Lithium Ion chemistries. Some real world examples being Tesla recommends most of their cars only be charged to 80% unless you need the range for a longer trip. But for their LFP cars, they recommend always charging to 100%. LFPs are...

Yes, it should be called “Low DC Cutoff Voltage” or something similar. Setting #29 for the 6500ex but I’m not sure what model you have. Here’s a chart I found that should allow you to get in the ballpark of Voltage/SoC

Yep. 2x more batteries coming soon! They are on their way. Then I’ll have my 6 slot rack filled out.

I believe so, to pass inspection for my offgrid home with 2x EG4 6500s I was required to have 2x ground rods spaced greater than 6ft apart. Bare #4 copper wire that runs in a loop from the panel to both ground rods and then back to the panel. Edit: The ground rods are connected to my Main...

Maybe a good idea to start communication with Signature Solar sooner rather than later. It seems like sometimes it takes a while for them to replace stuff if there truly is an issue. Also, they will probably give you some suggestions for troubleshooting or things they want you to test before...

https://www.kbb.com/car-news/study-electric-vehicles-involved-in-fewest-car-fires/ Here’s a short article talking about how EVs have fewer fires per car. Interesting what was mentioned in this thread about the age of EVs compared to gas cars. But one thing mentioned in this article that points...

There are a few experienced 6500 users in this thread already that might have other ideas as well. I imagine they will give their input soon enough

just wanted to post the info I have on Cycle life as well as calendar aging Cycle and life of battery vs DoD cycles https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries Calendar Aging https://www.frontiersin.org/articles/10.3389/fenrg.2023.1108269/full...

Since im running in split phase and already have 2x for that, i consider that having a spare. Ill be fine if i need to abandon running my 240v hot water heater and well pump for a while if one breaks and needs replacement. I mentioned 5 years because thats what the warranty is for, I kinda...

A simple way to balance them would be to just charge each one individually until they are full and then reconnect them. Post in thread 'EG4 USE vs BMS Communication Settings' https://diysolarforum.com/threads/eg4-use-vs-bms-communication-settings.52856/post-675501

Just upgraded the no-till off-grid farm a bit (well more of a market garden than a farm haha). So far it consists of a solar well pump powered by 2x 12v 100w panels in series, that pumps the well water from the well, up to the farm and fills 2x ~300gal cube tanks. Then to pump the water out...

The best would be cycling between 75%- 65% according to the chart I’ll post. But then you’re not using very much of the battery capacity. If you want to use 60% of your capacity, something like 85%-25% would be good. That would be better than using 60% capacity by cycling 100%-40% (and also...

Yeah you will probably have problems balancing all of them at the same time like that. Hopefully doing each one individually will work. Spec sheet says to start with low voltage cutoff at 47v, so you should be fine using that, but there is also this quote ill leave below about what is 20%...

I’m currently on a temporary Certificate of Occupany. In an off-grid home. Things in question that the electrical inspector didn’t know the answer to: 1. Busbars outside of the battery rack that split and go to each inverter - Do they need to be in junction boxes? They have covers over the...

Idle power consumption. 6500ex - 85w each so 170w total (some people have reported higher). 8000 - 115w Surge capacity. 6500 - 13kw each for 5sec. So 26kw total. 8000 - 12kw for 1sec. Max PV charging current 6500 - 120amp each for 240 total. (Divided by 6 100ah batteries is 40a. That’s...

The only way you can really tell is if one of your MPPTs is at a much higher voltage than the others, and resetting the one at 90v causes it to instantly rise to to the level of the others. Or if all of your MPPTs are at 90v and resetting one causes it to jump up to 200v immediately. I still...

here is a thread on fixing it. I was able to get mine fixed. basically just make sure its turned on in setting and then reboot the inverter. https://diysolarforum.com/threads/eg4-light-bar-showing-faint-red.59295/ all of the links below are from the above linked thread, so you could just...

- Can you check the battery voltage at the time of the pic you just posted? I bet the PV is ramped up to cover the loads while still keeping the battery at 54v Float. Then when you shut off the heavy load, it only needs a fraction of the PV to keep your batteries at 54v Float. You can see it...

How many batteries in your battery bank? Do they all go over voltage or just a few? Have you tried top balancing each battery individually and then reconnecting them? What type EG4 inverter and what type EG4 batteries?
