I almost bought SOK instead of Eg4 but they were out of stock. Damn. I guess they probably were out of stock for a reason
Anyways lessons learned. I'm still new to all this stuff so yeah signature was a bad experience and it cost me a lot of money to find that out, but I am really excited about being off grid ( luckily by choice ) so if it takes me a few attempts and a few systems to get to where I want to be so be it. I've made more expensive mistakes before.
So yeah... in summary what I learned from this, lesson number one is that the company you buy from is almost, if not more important than the product you buy, and second lesson is to always test each component first before you spend 3 days on installing wiring and conduit etc
