I have a MPPT 150/85 TR-Ve.can Charge Controller and an MPPT 150/70 - TR-Ve.can . These are daisychained and terminated according to installation manual. Both charge controllers skip absorption and go directly to float. This was occuring in Firmware V3.15 and when update was available I updated to V3.16. No change
When I discinnect the data cable the MPPT operate properly as stand alone units, Bulk, Abs, Float
Any ideas here?
They say the below quoted in the changelog.
It seems that, if you are not missing some other configuration, the bug is not quite fixed…
Fix bug in the VE.Can synchronized charging mechanism. In systems with two or more Solar Chargers connected in a VE.Can network, the bug could cause the chargers to skip absorption every day. It only affected systems where the Solar Charger is running its own charge algorithm. Systems with a GX device, DVCC, and either managed batteries or a VE.Bus system were not affected. This bug was introduced with v3.15, released in January 2024
