I want to design a system that can run 3 kw system in day time and also charge battery bank good enough so that i can easily run my 2 kW load at night for 9 hr backup. Now my question is how much batteries do i need ? lets assume i have 12 V 200 Ah Dry Battery with 60% DOD.
According to my calculation, 16 batteries are required to cater this. 4 in series and 4 in parallel. Does it seems feasible ? if yes than how many panels do i required to charge this battery bank and also run load of 3 kW.
I also want to know if i have installed 16 batteries and want to run 2000 W load in night so how much ampere will i get? will it be 2000/220 Vac = 9 Amp or 2000/48V = 41 Amp?
PS: There is no grid.
