Oeps lot of answers today
I try to read them all
I know that the Renogy need a D+ wire and I can make a switch in the line but I also have a BMV700 and maybe that one can switch the Renogy if the battery is 90% ful.
Otherwise the LifePo4 have a BMS which is between the battery and the BMV700 shunt. The otherside of the shunt is connected to the frame of the RV what mean that the BMS regulate the charging of the Renogy or am I wrong ?
Maybe my drawing clear what I mean.
I still have not bought a Renogy because they are not so common here in the Netherlands but the Victron Orion TR is very populair but much more expensive, twice the price of a Renogy.
