I recently bought a small remote cabin with another family and have been working on replacing the aging solar power system. Initially it had a Xantrex inverter that was very much failing and I could no longer get parts for, a 1kW wind turbine system that also was the solar charge controller but the bearings on the turbine were shot and it would no longer work at low wind speeds, 2x 250W panels in one string and 4x 80W panels in a second string, as well two AC-DC shop power adapters being used to charge the batteries from generator, all tied into 3 strings of 4x6V 225aH lead acid batteries.
I have since replaced the inverter, wind power, and panels with
Basically, think it makes sense, but I will be honest until last year I didn't know anything about solar and I am second guessing everything.
Is there anything that jumps out as glaringly wrong about my setup? Do I have enough solar panels to charge my battery? Would I be better off wiring my panels different?
I attached the data sheets for all the bits for additional info.
Any feedback would be appreciated. Thanks.

- Growatt SPF 3000LVM 24V - Max 2000W solar panels
- 4x 395W Q.Cell panels in two strings of two - Total 1580W, I believe it works out to roughly 74W @ 21a
- Raspberry Pi running Solar-Assistant connected to the batteries via 24V-5V buck converter pulling data from the Growatt
- In the process of swapping out the battery banks with a single Volthium 24V 200aH self heating lithium battery
