So last year I bit the bullet and purchased a 6 unit slave and master from rec.
They are great hardware guys , but software and manuals suck.
The relays work as expected. But.... you must use some kind of precharge system. I tried one on the second cold start.
Now is the delay module overpriced ? I dont think so. It's nice to just turn on the system and off we go.
My biggest problem was if there was an error in o e of the packs. Over/under voltage , temperature, balance......
It would fault out , then shut down the sunny islands. You had to reboot EVERTHING when the problem was corrected.
Then there was the pack assingments. They were all numbers as 1. You scroll through them for the cell group you want. Ex . There are 6 number 16 cells.
After 3 weeks of back and forth with Tine at Rec , everthing is flawless. If one battery pack is cut out , the rest keep chugging along. Sunny island stays working. If the bad pack corrects itself ,it comes back on line.
The original programming meant if anything goes wrong when your gone, your screwed. Now We can sleep well at night even away from the site.
