system output honesty [RE-wrenches]

[William Miller]

Marco:

I must not have been very clear, but you don't necessarily end up with the
same numeric float voltage setting.  Take the inverter with the lower
output and increase it's float voltage one increment at a time (I think it
adjusts in 0.2 volt increments)  while checking sell amps.  The change
should be immediate and obvious.  (If it doesn't improve, try decreasing
float voltage because my memory may not be accurate.)
