This makes sense and I think this is what I'll do. Thanks to everyone for the replies.

So....going back to my main question...am I safe with my current setup of 7 eg4 batteries and an LG6548? no added fuses.

I have a few EG4 batteries and an LV6548 all in one. The batteries come with a built in circuit breaker/fuse and I'm pretty sure I read the LV6548 has built in fuses. They all connect to the same bus bars. Do i need a T Class fuse for each battery too? Do I not need any more fuses? Am I safe or...

I added 3 batteries about a year after i got my first 3. There is no noticeable difference that I can see. I'm sure more time will add to that, but I think worst case is that you have some that charge up quicker and you'll lose a little bit of the capacity as those will discharge into the weaker...

All great info guys. Thanks for clearing this up. With all the inverters out, it was pretty hard to see why the 6000ex is not the go to seeing as it does 240v. Nobody mentions this 3000 watt limitation per leg and if you want to wire up your house or a cabin, you have to be careful with 3000...

One thing that I found interesting is that the manual for the 6000ex calls for 10awg wire for the AC output wires. Got me thinking there was no way it supported 6k watts on a 10awg.

The EG4 6000EX runs 240 volts on two legs. Does it max out at 3000 on each leg? If I have a sub panel and one leg goes to one side, the other leg to the other side...what happens if one side of the panel (through a few breakers) wants to draw for example 4000 watts?

My 6000EX puts out 49-50v DC on those inputs.

Thanks!!

I guess my main concern is that usually it's been my experience that Lithium likes to be slow charged at the higher voltages. I'm worried that doing the opposite could shorten lifespan of my batteries.

Thanks, but they're separate systems that share the battery bank.

Each battery has 4ft 2 awg cables going to a 300amp rated bus bar. Inverter 1 has 4ft cables too and inverter 2 has 5ft cables all 2 awg.

5 minutes max and usually it's like 30 amps and and sometimes hits a minute at 50amps

My poor memory says I have bulk set to 58v and float at 54v. Batteries are not getting warm as far as I can tell.

I have 6 of the EG4 48v batteries. They never are all at the same battery percentage according to the BMS software. No biggie, they're close enough and work great. I get all the rated power out of them. The issue is that when I charge them up, they don't reach 100% at the same time. One battery...

Ya, I'd say there is definitely a need to create a dump load :ROFLMAO:

Actually, I've done quite of bit of this. Works great.

Ya, that's what I'll do or bring a big towel to cover one of the panels. I think that'll lower the string voltage too. Maybe do all of the above.

So that's what I've read anywhere but it's hard to fathom the idea that I could touch a high voltage wire and be fine. Last time I setup panels it was around 200 volts and I was able to make the mc4 connector ends, touching the wire as little as possible, but still touching it here or there and...

Not that I want to just go out and touch the live DC wire, but I'm curious. It seems if I touch just one of the DC wires it doesn't shock me. I've done this with panels pushing 200 volts. Why does it not shock me? Is there a point where it would shock me? I am looking at getting a second mppt...

I will buy some thicker wire and report back once that is set up. Thanks for the tips.

I have 3 of the EG4 batteries connected to each other with 2 gauge wire and a 2 gauge wire going to the inverter. 10 gauge wires for the breakers/loads. It happens at all times no matter if the batteries are full and it's the only thing running or if i'm running lots of other things. One...

I have an LV6548 setup with a nice battery bank and have a sub panel with breakers etc etc. A dedicated line runs to the washing machine and dryer, a separate for lights, and so on. When the washer is running, most lights in this system flicker in line with the back and forth movement of the...

So the LV2424 has 2 x 40 amp fuses inside for solar input and they are not removeable. I blew them. Yes, I know, my mistake and now I have in line fuses hooked up. The odd thing is that you can't remove these fuses. What is the point of non removeable fuses? They're literally soldered to the...

This is true, but you still have this same draw on your batteries whether the system is idle or not. If you power 500 watts, it's not like the idle consumption 75 watts goes to 0 and your batteries pump out 500 watts. I figure he's looking at how much power he'll burn overnight. Either way, he...

Great, I got this set up and it worked fine. Hooked up the charger to a smart outlet and can now turn it on and off or set a schedule for it from my phone.

I have 2 of the eg4 48v batteries hooked up to my lv6548. I want to connect a 10 amp battery charger for occasional use but want to leave it connected to the batteries at all times. I would unplug the charger when not needed and just plug it into utility power when needed. Are there any issues...

Yes, it is extra power used on your batteries. So if you need to power a 200 watt light, you can figure that your batteries will output 275 watts. If you need to power a 500 watt light, figure your batteries will output 575 watts. In reality they'll probably power even more than that since the...

Next question: Anyone know where to buy a raspberry pi 3 or 4 these days?

Wow, very nice. It's a shame you have to jump through hoops and buy extra gear to get this type of interface.

I've seen on posts that it's not good to force lifepo4 above resting voltage when at full charge so I have my float low. Can anyone chime in on that one?

I have a new LV6548 and 2 EG4 batteries hooked up. The battery percentage is all over the place and is clearly not accurate but the batteries are able to fully charge just fine but the bms is stopping charge. I really want the inverter to stop charge just a little before the BMS. And I want the...

Can you tell me more about the MQTT broker? What use does it have for this software? Is the Victron Smart Shunt not able to connect directly to the pi? Why use the home assistant software?

Oh, I think you are right :)

The panels come with a 15amp fuse in them...so should my strings also have the same size...15amps?
