Yes. Plan on at least another 10 panels (total pv = 9.8kw) and another 4 pylontech batteries to existing 2 (total storage 21kw BUT of course at 0.5c discharge only).
That’s not really so much to use in a day. Multiple geysers, some high draw IT equipment and you have demand. My best was 70+ kWh for the day and I dont have one of those spinning meters
