BTW, the BZ charge controller (MPPT500) has been fine since returned from fix-up. I think the display is not very accurate, but not too bad: The voltage shows a bit higher than my DVM or the voltage display on the inverter, and the currents displayed don't quite make sense sometimes. E.g., if the input (PV) amps is 3 and the output (battery) amps is 15 that's an impossible 5x "current boost" as the voltage ratio is only 3x or so. But it does seem to charge the battery well, with peak output current on sunny days around 20A as it should be, and even on cloudy days and at dusk the battery is up around 14V. I reduced the float voltage a bit from the factory setpoint, to about 13.8V (by my cheap DVM) - or about 14.1V as displayed on the BZ.
