Well sorry to report that I am once again looking for advice from the experts on this site that have been super helpful in the past. I was supplied with a faulty design from the beginning of this process trying to get an off grid system set up at my cabin in Northern Saskatchewan. I rectified the design according to the advice from the experts on this site......SolarQueen, Hedges, GSXR1000, Digital Steve, and Steve_S just to name a few.
I had everything hooked up with a new electrician as per their advice. However there was some down time in the winter that the system wasn't working due to the initial poor design and as a result the batteries were just sitting in -30 Celcius(-22F). I have 4 Rolls 6v AGM batteries that I bought brand new in April, 2020 and paid over $2000 for all 4.
Now, according to the new electrician I have hooking the system up, all 4 batteries are completely toast and will not hold a charge!(after trying to cycle the batteries at least 10 times at a specialty battery shop and they would not stay up). He says they all need to be replaced.
Obviously I am super disappointed that I essentially through away $2 grand on these batteries and now have to replace them. My question to the experts on this site......is this possible that the batteries are completely useless after only 1 season of use??? Is there anything I can do??? I looked up the batteries on the Rolls site and they apparently have a 3 year replacement warranty but I would assume this doesn't apply as the batteries I guess froze due to the cold temps and faulty design??
Any help or advice would be very much appreciated!! Thank you in advance!
