I have a 2220 Watt Solar Array. This array is managed by TWO SmartSolar 150/100 MPPTs. This configuration has been functioning flawlessly since installation and setup in Dec 2023. This ended when I Upgraded the MPPT firmware to version 3.16. The MPPTs have refused to go to Absorption Mode, but instead transition directly from Bulk Mode to Float Mode. Is this issue with Firmware version 3.16 being addressed and when can we expect an update? If the update is not on the books, how do I go about reverting the Firmware back to 3.13?
