Hi,
I hate to say this but the BZ controllers are not good. In fact in a head to head test with a PwC the PWC outperformed the BZ MPPT.

outboundwest,
It may depend on what is selected for set points. What controller do you have? Have you changed the stock settings?
the set points are per my batt manufacturer. I used some simple MPPT controllers made by BZ Products in the US. I don't have displays inside my camper. My Magnum 3012 display, because it has the batt monitor, gives me a net amp figure. This net figure is the gross on the controller, less the load (devices + phantom), which is fine for me. I wanted simplicity.
Someone answered my question I think. If I'm under good sun and if in BULK, harvesting 55 amps, but then in FLOAT, the controllers show only 25 amps, in the same sun, then that answers my question.
I thought the controller always showed the max potential harvest, when evidently, it is only displaying the usable amps based on the needs of the batteries.
I specified Morningstar and forgot to order them before arriving at the solar place. The fellow had been using these for 20 years, so I tossed them in. They were making about the PV panel labels.
