Basic solar setup - 2,400W with 14,400w storage

This is the start of my solar setup. I have two 1.2Kw panel sets on trackers and 12 LiFePo4 12v batteries setup in 4S3P configuration. I'm still tuning it to get things stabilized. Will be adding one more set of panels to bring it up to 3.6Kw. in reality, that will typically only generate 2.4Kw even in good sunlight. These things just don't out out what they say they do. That said, it's possible that my wiring, etc. may be causing more loss than I realize.
More to come as I figure this stuff out. I'm putting links to the batteries, solar panels and inverter I'm using. This is the first video where I'm using Amazon affiliates so if you happen to purchase one of these items, through this link then I'll get something for it.

Nice setup I'm curious about the battery setup in series, and parallel I'll research that interesting. You have a lot invested hope everything works out for you.

[@DavisOffGrid]

Thank you! The series/parallel is a common setup for solar. It all depends on the inverter you are using from the pack. In my case it's 48V and I have to match that, hence the series. But a series bank with 4 12V 100ah batteries is only 48v at 100ah. And I needed more capacity, hence the 4 parallel rows.

@@DavisOffGrid got you I like it.

Sweeet setup. The solar array is super cool with the wind sensors and moving panels is super cool

[@DavisOffGrid]

Thank you! I like the trackers. Actually alhave a 3rd one, but haven't had time to setup.

[@509tilouis]

Nice setup. Just remember those batteries have to be charged at atleast 0.2C which means 20amps per series bank. At 48v you'll need (54.6 by 20 amps = 1100w). You have 3 series bank so you'll need 3*1100w. Standard solar panels produce typically 75% of their rated power in full sun (around 11am to 2pm). So 3*1100w/0.75 = 4400w. You need at least 4400w of solar panel at rated power to effeciently charge them. And of course if you have loads you have to add their power consumption to that. Also note that lower amps will still charge them but will take an eternity even if you discharged them at 90-80%.

[@DavisOffGrid]

Thank you. Great information. I'm still learning here. Making some progress. I need more panels.

[@DavisOffGrid]

It's kind of a list! I'm sure some are self inflicted, but it's been a learning process. I've worked out most things. My biggest remaining issue is that when I need to run a generator because the batteries are low, it's been difficult to get the charging and the bypass to the RV happy. I'll try to do a video in the next several days.

[@FJRyder]

I know you said you would bring it up on another video. But what kinda problems are you having?

[@DavisOffGrid]

I'll work on that video sometime next week where I'll lay out my issues.

messing cable and messing battery cable look horible can u get those battery server rack

[@DavisOffGrid]

Yep. I can get a ton of stuff, but working on basics before cosmetics.

[@ryan99gsr]

​@@DavisOffGridmy solar system is smaller like this and I'm always improving. I'm also running a camper. I had 1/0 wire loops between my batteries like yours forever. Yesterday I removed them and installed some flat busbars between the series strings that I found on Amazon. They are meant for individual cells so I had go drill the holes out bigger but they had a length that is perfect for those batteries. I wish I had done it sooner. Especially for as many batteries as I plan to do it saves a ton on wire and lugs.

[@Madsci-zy8wm]

Nice solar array but a very poor choice of inverter. lightweight, High frequency, transformerless inverters like these offer a far poorer surge capacity as well as a much shorter life expectancy than a real inverter that uses low frequency, transformer based inverter tech. You'll be lucky if you get even two years of service out of this high frequency inverter.

[@DavisOffGrid]

I hope your wrong, but will keep your input mind when adding additional power.

[@ryan99gsr]

​@@DavisOffGridI've been using an eg4 3000w high frequency inverter for 2 years and it hadn't missed a beat. Planning to add 3 more to it in the future. I like the small inverters
