April 18, 20233 yr Hi there, I recently had a SunSink single phase 5.5kW hybrid inverter with a SunSink Batt 5.32 and 6 solar panels with a max supply capacity of 3kW. I have recorded a solar supply of 2.7kW ( Charging the battery without Grid connection) average load is about 500W so my panels are more then suitable to maintain my batterie charged and keep my demand during the day. I want to make sure that my battery is only charged from the grid during night time. I have my setting as it follow ( Load shedding currently) but is not working as the battery and my load gets connected to the grid during the day. What am I doing wrong?
April 18, 20233 yr Can you share your System2 screen? By nature the inverter will dip into the grid (when its there) in order to balance the power needs between the house, PV and battery. For example, If the house suddenly requests 2kw of power - the MPPTs can take a second or 2 to react to this and in that gap the inverter will use grid until the other sources react. There is no setting on the SS currently to switch off grid during a period. Edit: Oh and with your SOC settings so high (80%) even for daytime hours the system will use the grid to power loads until that SOC is reached, e.g. say its 9am and battery is only at 40% because you had overnight loadshedding, until the battery gets to 80% it will use grid to supplement PV. If you want it to use PV and not grid during sun hours set the SOC to something lower then tick Prioritise Load on System2 Edited April 18, 20233 yr by mzezman
April 18, 20233 yr Author Hi Mzezmam, thanks for your reply, appreciated. Seeing that system1 timer is set only for 1-5 and 23-1, should the Grid not only come online during that time? Previous System2 setting Now new setting as per your recommendation. Your feedback is much appreciated. Kind regards

Your feedback is much appreciated. Kind regards The ticks for System1 grid are to enable the battery to be topped up to that % by the grid. If there is no tick it wont top up the battery using grid
April 18, 20233 yr See how the system performs tomorrow with sun and those new settings then we can make tweaks post that
