He we go. First charge in series. Gfp 280 from Michael. All arrived in perfect shape. The braided busbar were a nice surprise. 2.5mm thick on the smashed ends. Studs are 8mm , aluminum. Didnt like that part , but they torqued down just fine.

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...

Sent message to Rec. Waiting on answer. I went to take apart a battery pack and add insulators between the cells. Turned off one of the slave to deeneregize the pack. 30 sec later , the Sma Si6048 shut down and gave error that bms timed out. I hope this is a program fault and not a feature...

I'm a REC bms guy . So trying to figure out the daly a guy gave me Its 8s 200 amp. Plastic case with fan. It has the main cables, a 9 pin cell cable. Then there's the temp wire. Next to that is a 3 pin socket. Am I to assume this is not a smart bms , bluetooth capable ? How the hell do you...

Guys If you have time, I'd like to pick your brain. Ultimate goal. 1900 square foot house. Super insulated as I am building it myself. Summer temps 120 degrees in Az. Fixed mount ground panels. Have 50 , trina 250's so far. Our households consumption peak month was 2054 kwh. Batts will be 280...

Anyone is one ? I'm looking for someone to draw up a set of house plans to submit to building dept. Everyone I have contacted is 9 months out or price out of this world. Greg
