Don't know how you are charging, but the batteries should be connected to a management system, otherwise the batteries will become unbalanced (each battery is separately controlled and charged with a management system) . Also, you can't connect two inverters together unless there is a system to synchronize the phases. The expensive charger probably has a timer circuit that shuts off in 20 minutes. Spoil the warranty if you want and look for common timer chips like a LM555. The lower charging voltage is by design to increase battery life.
10-4 that timer chip is for the birds. The batteries are charging from the solar. I only use the other generic chargers to help the solar when it's been cloudy for a week
Through the video there were a few things but what is your main concern. It was a short video and it's the first time I've come across your stuff. You may know but I don't know that you do. Just because you have a 300ah battery bank doesn't mean you get 300 hours. Alot will depend on the load which you are demanding from the bank. Being lead acid batteries you should be safer to assume that you can only really discharge them to around 50 percent capacity in optimal conditions such as temperature and what you are putting back into them as you use them. In a perfect world your 300ah batteries would be good for 300hours at a discharge rate of 1 amp per hour. Which is where we get back to what you are trying to run off of this setup. Also you must keep in mind that that inverter also uses power to run which is why it came with an on off switch. Ideally it would only be on while using the powered stuff that the inverter is there for
As for the fuse issues you are having there are a few things to consider. Where you have the in line 30amp fuse I would recommend a 40amp water proof circuit breaker. But at the same time before that you should check for any shorts to ground for the circuits. The system you are running is a great way to get into solar and I myself own two arrays of these systems. Without my books or notes in front of me I can say that I only expect 3.5 hours from each of my la batteries with the loads that I run. Many things come into play in a system even this small. The flow of power is important. I am to assume your 4 panels are using a 8awg wire to the charge controller. This is good however as you add length you also add resistance to that line which will cause the amperage to rise. I don't know if you have any extensions on that line from the array to the controller but if you do it is something to keep in mind
Not a professional by any means if this field however I have done it myself and have roundabout 18 years experience in the automotive industry and have worked many jobs in electrical as well as wired my own house
Thanks for the input. It's very helpful. I'd like to think I have a basic understanding of this solar but I always want to learn more. All I run is a fridge and recently setup a starlink internet system. My main concern is that when I only had 2 batteries I could run just the fridge and only go down to 80% capacity then overnight to maybe 70% but the next day even if it wasn't optimal sunlight it would go to 100% or just about but we had a gray week and I drained then to 0% on the controller which is actually 10.9v for the batteries and since then I can only get back up to 60 or 65% and they will drop off very rapidly comparatively to before where it seemed slow and normal to me. This is when I added a 3rd to hopefully stabilize while also increasing the overall capacity of the bank but it hasn't done any good so far
Led acid you have to cut the amp hours in half also so if you have 300 its only 150 of usable AH
You also need to pull from 1 positive at 1 end of multiple batteries and then negative to other end of multiple batteries.
Yup that's what I've been told. I have the solar feeding neg of number 1 and pos of number 3 then the inverter pulls from pos 1 and neg 3
Wire your solar panels to 24 volts. The charge controller will be more efficient that way.
You cant add new batteries to old batteries
nice setup cool but some said not to take those battery down to 0% there about 20% or 12% not really know ok
keep up good work 🥰🥰🥰🥰
There will be more updates as I go but your right 0% is no Bueno even though the battery should be fine being only 10.9v

Pull the sticker off the top of the battery and then you can check water levels.
That's a good call. I wasn't thinking about the water cause they're only 3 months old but i should check it
Im interested in helping if i can. Not saying i know everything but i may be able to help

What fool uses crappy vintage lead batteries anymore?
This fool I suppose
