I'm looking to evaluate the output of a solar setup using an SmartSolar MPPT 17/15. The setup currently uses a 12V lead acid battery with a DC fan on the "load" output. The SmartSolar is set to turn the fan on at a high battery voltage threshold, and turn it off when a low threshold is reached.
This ideally means the solar panels are always being driven in MPPT mode, allowing recording of max power throughout the day.
However, when monitoring this system in VRM the periods when the fan is running show a negative solar yield - with mention of "battery watts" I assume yield is being taken from the current flowing in/out of the battery.
The "Solar Charger PV Voltage and Current" widget appears to have the correct data as both readings remain positive, but is there anyway to translate this graph into PV power output and graph it?
