Hello

I need to clear some doubts about solar power.. I will write down my theory please correct them if i am wrong.

I must tell you that i have absolutely no knowledge of solar power system. I have tried google but couldn't understand how solar panals are calculated and how many batteries and what volt system.

If someone has 18x 245w solar pv, then what volt system should he use, 12, 24, 48 ? and why?

If using 48v system then how the panal connection will be like?

I would connect 4x panals in series to make 48v (12x4) and 14x panals in parallel to make total of around 3600 watts, is this correct?

For 3600watts of power how many batteries would require?

4x 12v battery is must to make 48v but how many amp hours(AH rating) if i need backup of around 5-6 hours?

Also i would use an AC inverter to power my electrical appliances.

How many watts or kva of inverter one would require to handle 3600 watts?

If anything is not calculated correctly or not correct please correct them and give me your insight thoughts on it.

Regards!!
