I'm also getting Error 32 on an LVX6048. However, I didn't do a firmware upgrade and it is generally working fine other than.... at roughly the same time the unit stopped powering up unless it has active connections on both Battery and Solar inputs. Once I power it up with both it will stay on if I disconnect either. I also saw somebody reference an "unpowered device connected to the USB port" so I tried to disconnect the device I keep connected to the USB port with no luck.
For ~13 months now the inverter has worked fine in off-grid condition with the inverter (aC output, silver button) OFF. The unit maintains battery charge for several 48V DC loads (cameras, network, etc) unless I"m there in person and need 120VAC. Now unfortunately I'm left to having to leave the AC output on all the time which is rough given the standby losses on that unit. Anybody else with similar experience or a solution? I'm on firmware 63.03
