August 14, 20242 yr Hi All, without overomplicating the question: how long can I leave my 25.6v 106ah 2.71Kwh SVOLT *No Comms* in Bulk mode? 4 hours / 2 hours / 8 hours? And, after X amount of time in this voltage, will the built-in BMS cut-off the charge? *Yes, my MUST has the float bug, yes, I've worked-around it, mostly.

Depending on how strong your charging is as the inverter should stop charging in bulk when it reached the manufacturer's charge level. Not really a time based setting. Stop at correct voltage happens when current has dropped to close to zero being 100% charged.
August 15, 20242 yr With the Svolt BMS the fullpack voltage and fullpack current m amps is set . The battery will stop charging at the set value and the BMS STATUS will display FULL. Edited August 15, 20242 yr by Chris Louw

USR mode gets to bulk then drops to float - Li mode hits bulk and stays there for hours with 0.5a and the MPPT icon off. I assume it's just the nature of the cheapness of this thing. Changing from USE back to Li immediately sends back to bulk... I imagine the BMS has long since disconnected the battery from it's charging cicruit and the inverter is still pushing 28v lol.
