The information was much helpful. At the point when you are finished with load calculations, you need to assess the PV panels maximum capacity (PVMax). The size of Inverter should be 25% bigger than the total load due to losses and efficiency problem in the inverter. Assuming 90% efficiency in our case, the total energy supplied by the battery to the inverter would be given as; Energy supplied by the battery to the inverter input = 2700 / 0.90 = 3000 Wh/per day. A system designed for the highest demand will ensure that the system is reliable. The sizing of the cables depends on many factors such as maximum current carrying capacity. Under sizing of the cables will result in energy loss and sometimes can even lead to accidents.
