Open loop applications for the Powerflo16

[CaptainSunshine]

New to forum, first post. Thank you for your engagement here! We could not have achieved what we have so far without you all taking the time to write and exchange ideas in this forum.

Thank you especially to @mvrck for your very informative video shared in this thread.

We are running the XW PRO in open loop with the PowerFlo16 after upgrading from 6 x PHI-3.8-48-M (no communication). So far relatively good performance. Batteries communicating with the Schneider Insight using CANbus again using a separate video from @mvrck. Thank you!

We've seen the notes on Absorb and Float voltage. Any thoughts on Bulk/Boost voltage settings? We are running with both SOC and Voltage control enabled in case we lose communication with batteries. My understanding is that we can still run on voltage control in this case instead of SOC.

I also have an interesting warning we received a few days ago after flipping on a rarely used exhaust fan. The XW PRO shut down with a Fault 71 and posted the following message in the log: Cause: Battery discharge current exceeds the discharge current limits sent by the external BMS.n.

Surprised we exceeded max discharge current for batteries without causing trouble somewhere else. Batteries in the system (see signature) do not seem to be the limiting factor.

Any thoughts on these topics appreciated!

I think there is a setting on InsightHome for the inverter to issue a Warning or an Error based on BMS activity. I set that for Warning. It could be that the battery was full or near full and was instructing the system to taper charge. Or the battery was low and also was trying to lower current draw? Not sure either way, but it was set to warning, at least you would know about without losing power.
