Johan van t Wout Posted 2 hours ago Report Posted 2 hours ago "Hello, I have a question regarding the following. I have designed two nearly identical systems in PVSOL. Both have 4.4 kWp of PV capacity, the same battery type with 19.2 kWh storage, and both use a hybrid inverter: a Growatt SPH3600TL BL-UP and a Solis S6-EH1P3.6K-L-PLUS. There is such a large difference in battery losses that I don’t understand the cause. Who can help me? I am uploading a spreadsheet with all PVSOL input values for the battery, the PV inverter, and the battery system. With the Growatt configuration, the loss is 819 kWh/year, while for the Solis, it is only 233 kWh/year." Growatt Solis I hope someone can help me out on this. Many thx Kind regards Data Solis and Growatt PV Inverter - battery system and battery.xlsx Quote
