Thanks for reply and the link, I will study that next. Understood and agreed, I guess I have no logical reason to believe that it wouldn’t work as expected just because of this particular behavior with the remote switch. Disconnecting the B.T.V cables does indeed drop the M.P.P.T output to 0A. So that control aspect has been tested and confirmed.
Do you have any thoughts on the second item I had listed by any chance please? The work around on this is to simply alter the current limit value or cycle D.V.C.C off/on after the remote switch has been turned back on but that is not ideal. What concerns me is that it’s loosing it’s “Authority” to begin with, if that’s the correct term, after this remote switch operation. As an example I set the current limit to 30A, watched it regulate charge at that. Then cycled the B.M.S off/on, on resumption of charging I witnessed maximum charge of over 100A from the multi-plus. Simply moving the current limit to 31A immediately resulted in to the system then returning to normal behavior.
Thanks again for your thoughts and feedback pwfarnell…
