Hi All, In the past 2 months, I've had 2 separate clients with 48 volt SW systems have their TM500 stop resetting amphours - even after there is no current flowing into the bank for hours. The meter never goes below "0" amp hours and always shows "Full" SOC. These are TM500s that have behaved properly (at least in that way) for years. Anyone else ever seen this? Another time bomb? Any fix other than replacing with a Trimetric 2020. I've seen bizarre behavior from the TM500 before, in a 48 volt system setting up some high frequencies which effectively shut down the C40 on the system, but haven't seen this anomaly before these 2 systems...
