Blue Sky 3024dil cut in voltage
Hi All, My solar panels were covered in snow this year. The result was the house batteries got down to below 8 volts. The sophisticated charger in the Blue Sky refused to send power to them. ...

How thick was the snow Don? Im curious as I have seen charging through a bit of snow and want to know how much it takes to shut it down.
If you would have had LiFePO4 your BMS would have shut them down and protected them from over discharge you know ')
I've seen charging at 3 inches of powder snow, approximately 0.3 of an amp. However this was hard drifted. Heavy wet snow would be even worse.
If I had Li batteries they would require me renting a shop to warm them up before I could safely charge them, if the bms had shut them down. Since the starter battery was also dead that would mean towing the RV. Many of the Li formats I've investigated require a high voltage to switch the bms back on. So I'd probably require a special charger for that purpose.
As I'm 75 and a long range planner, I'll probably not get my SiO2 jars. My plan is to sell the RV at age 80--or give it away to family. I can't justify spending $4000.00 for 700 amp-hours of battery bank. Not when I can get over 500 amp-hours of reconditioned telco jars for $1 per amp-hour.
