I'm struggling to find how to set up the inverter correctly.  Any assistance would be much appreciated. 

I simply want to

- minimise grid input, so use the battery down to 25% SOC whenever house usage is greater than solar output

- import when solar and battery can not cope, but only for house usage - not to to charge the battery

- export excess to the grid when the battery is fully charged (as I get paid for this).

Is there a way I can set up the system to achieve these requirements?  

Thanks

 

Make sure "Use timer" is ticked on this screen

1 - For all timeslots that you want the battery to be at min 25% set the SOC to 25% - note that solar will charge your batteries as high as they can go based on the load and generation power. So the 25% is a minimum that your batteries will run down to. At 25% the house will draw from the grid to service the loads. If there is no grid (say during loadshedding) the batteries will continue to run down until their shutdown %

2 - If grid charge is ticked then the house will charge batteries from the grid. If you do not want this then make sure its unticked

3 - Tick Zero Export, Tick Solar Export and Priority load (this will export excess PV once the batteries and load are serviced)

Thanks for replying, I will set this up today!
