Hi everyone, long story short I think I have done goofed up. Now I really need some help.
In an attempt to put together a solar system for an off grid cabin I am building I purchased the following components...
- 16 of the SanTan Solar T Series 250W Panels
Some specs for the panels..
Rated Power: 250W
Open circuit voltage (VOC): 37.6 V
Max power voltage (VMP): 30.3 V
Short circuit current (ISC): 8.85 A
Max power current: 8.27 A
- 4 of the LiFePO4 12V SOK Batteries
Some specs for the batteries:
Charge Voltage: 14.6V
Max Charge Current: 50 A
Max Discharge Current: 100 A
I also have a Growatt 5000ES
I made a post a few weeks ago asking if anyone could review this system and a few people helped me out, pointing out that there was a problem with my system. I was shown that for this system to work (running my panels as 8S2P and to be compatible with this growatt) I would need to purchase 4 more batteries, in order to run the batteries in 4S2P to achieve 48V with 200A max discharge current.
My 4 batteries max discharge current of only 100A would not suffice. To solve this problem I planned on buying 4 more batteries. However, my cabin is on a ledge, a hand driven well didn't work out, I had to have a deep well drilled, and badda bing badda boom I am out 12 grand...buying 4 more batteries does not seem to be possible now.
My question to you is... Should I try to return/sell my all in one Growatt and downsize, so I can get by on 4 batteries? If I do so, I am honestly not even sure what all in one to switch to or what that would mean for my panels?
I am doing my best to figure it all out but at this point I am overwhelmed and doubting my ability to put this together.
Thank you for any advice.
