I have two "Voltronic":"InfiniSolar V x 2" also known as "IGrid SV-IV-5.6KW" from EASun. I have them in parallel config attached to pytes lithium batteries, solar, ac input attached to grid and the output to the breaker panel.
Every hour on the half hour the inverters start drawing power from the grid to supply the load for between 15 and 30 mins even when there is plenty of battery capacity. See solarassistant chart attached.
I notice that the inverter mode is switched to 'solar\battery\utility' during these periods and "solar/battery mode" when not. I have the inverters configured as follows during standard rate periods, the idea being that the load will be serviced by battery and/or solar only as electricity per kwh is 4 x cheap rate.
output_source_priority = 'Solar/Battery/Utility'
charger_source_priority = 'Solar only'
For cheap rate periods I set the following, the idea being the grid will charge the batteries when electricity is cheap as well as service the loads.
output_source_priority = 'Solar/Utility/Battery'
charger_source_priority = 'Solar and utility simultaneously'
Does anyone know why it is using the utility and how to prevent it? I thought of adding an automated wifi breaker to disable the ac input during these periods but my understanding is this could damage the inverters due to surges or inrush. Is there a setting i'm missing? Thoughts?
