Hello, I want to put panels on my roof (max. 11 or 12) with a Growatt 5000 ... and this battery EG4 Budget Model 48V. I never need more than 5000W at the same time. So my question is if anyone can say what I need? These Growatt things look easy and I would like to be able to bye each 3 months an extra battery till i have 4. Is that posible and what panels do i need? 12 v or 24 or 48 or 700 I really dont know. Thank you for responding. AAAH something else. My house is in Granada, Spain. Lot of sunny days a bit cold in the winter and in the summer a lot of days near 40C degrees. Something else: First i will use the grid 240V but next year I will not anymore with 4 batteries of each 5kWh. These are the solarpanels which I can find in Spain: https://autosolar.es/paneles-solares Please anyone???
