Hi guys been using emoncms (self hosted) for about 2 months now and it is awesome. Before now I use to manually upload my usage data to pv output… Anyway to understand my question here is my setup.
I mainly use emoncms to log solar generation data. I live completely off the grid electricity wise. The data being logged are from 2 victron solar charge controllers and a victron battery monitor. (I used the Victron interfacer with emonhub)
The key feeds like real time PV voltage, power current, peak power, battery charge and discharge current all come from the charge controller and battery monitor.
I also get figures on total energy harvest for the day in kilowatt hours. It is the last figure that I want to log into a cumulative figure of total energy harvest for the week months and Year. I have not figured how best to achieve this. I have them graphed but you only see individual daily figures not cumulative. The daily energy harvest is already supplied by the charge controller so I don’t want to generate it from the emoncms from PV power log to feed and to power to kwh. I just want to log the daily harvest figure from the charge controller and make it cumulative. The figure is already in kilowatt hours. The energy yield figure starts once PV starts to generate electricity and it increases until 7pm when PV stops generating and the generated yield remains till next charge cycle.

Suggestions would be highly appreciated.
