How to set up self-use and if needed time of use to set charging times on RHI hybrid inverters

1) Make sure you have the right battery selected on the inverter.

Advanced Settings (password 0010)--Storage Energy Set-- Battery Select

Set an Overdischarge SOC of 20% (value down to which the inverter will discharge the battery) and Forcecharge SOC for the battery of 15% (value bellow which the inverter will start charging the battery from the grid.


2) Select the correct type of meter

Advanced Settings--Storage Energy Set-- Meter set--Meter Select--Single phase meter (Acrel) or Eastron single Phase meter


3) Set Storage mode to self use mode

Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use--ON
Make sure the other modes are disabled


4) Enable charge from grid function

Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Charge from grid--Allow


5) Set time charging to ON - if the customer needs to charge battery during lower tariff periods (for example during night time)

Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Time of Use--RUN

Select a charging time to include the current time to strat force charging the battery

Advanced Settings--Storage Energy Set--Storage Mode Select--Self Use-- Time of Use--RUN--Charging time

In this case you don't need to select a discharging time. Just set discharging times to 00:00-00:00

6) After all, this is set, I suggest turning off a load and checking the inverter's behaviour.
