Dear Community,
I've got my SBV4600 + B4600 some months ago. Most of the functions works fine for me, but the fans are terrible noisy. I only use solar Input for the system. Since some days I recognized that Most time only the SBV itself is charging by the solar Input and the B4600 Not, maybe because of rainy days and only little solar Input. For this reason charging states for B4600 and SBV4600 are widely different. At some Times the SBV than Shows From one Moment to the next 100% charging state although the B4600 could Not be Fully charged and the SBV Shows Error Code 217, too. When I Connect any load everything works fine and charging will start again after charging state will be under the limitation, but I can't get all the Power Out of the system - means it was Not Fully charged.
Now I think about to Update my SBV hoping to fix the issues described, but I have read many about broken SBVs after Updates. The SBV Shows me Updates for MASTER, AC and DC. In which order I should do the Updates and what should I consider to Not broke my SBV? What means Error Code 217?
Current state for my SBV:
MASTER 1.0.42
DC 1.1.4
AC 2.2.1
For B4600 there are no Updates shown.
Many thanks for your Help!
