Larry, because these MPPT CC's are bi-directional (for
efficiencies' sake), they can convert a large current<br>
at the battery side to a smaller current at the PV side if not
adjusted right. Normally this is just taken<br>
care of and reduced to a bare minimum by the controller watching
the voltages and currents carefully.<br>
It is technically possible though for things to not work exactly
correctly. I am not saying that this is<br>
for sure happening, but it is possible. The ramping up in
battery voltage from the chargers should<br>
be plenty slow enough for this not to be a problem but I am wildly
speculating that this could happen<br>
and cannot rule it out. There may of course be something else
completely different happening here<br>
though.<br>
<br>
If CBI breakers are being used, these are known to be extremely
fast at tripping when overloaded.<br>
<br>
Also, what, if any SPDs are connected to the system ?<br>

After the Magnum Inverter/charger samples incoming AC power, they
have a slight delay before starting the charger. Then, they ramp
up current slowly.

<div class="">Even so, how will any current from any other
source pass through the breaker unless the Classic is
presenting a load? I suppose something else could be wired
through the breaker but I’m guessing Daniel would have looked
at that.<br class="">
