i want to design a off grid solar system to run a load of 450W.
the tech specs of module i want to use is as follows
Power (W) ------------------------ 270 W
Max. Power Voltage (V)------------- 36.72
Max. Power Current (A)------------- 7.45
VOC Voltage (V)-------------------- 44.49
SC Current (A)---------------------- 7.95
Please suggest me
1.battery size (for 2 days autonomy)
2.charge controller size ( using Steca germany products)
3.inverter size ( using studer germany products)
4.Number of modules in parallel and series
5.what would be the PV plant size
i already designed this system but i feel every time i do some minor mistake which make my system oversize........
So need inputs from experts......
Thanks
