Series and parallel connections of solar panels part2

[@junaid9944]

Excellent explanation specifically for non technical person. Thanks

I am question... For running 10hp motor. Voltage range =380 to 440 Amp= 13 Which option is best..... Plz guide. I have 20 solar panels of 450 watts. Their specifications are...voltage =41.5 Amp= 13 Which option is best....??? My opinion is 2 sting of 10 panels series then parallel.... What u say....

Ok, Is the motor dc? If yes then Depends on the controller or dc voltage regulator you are using,if it can carry up to a 1000v then do all series reason for this is because the open circuit voltage is 41.5 Close circuit voltage will be around 38v 10*38=380v and you need a bit more than that to power the motor because of voltage being unstable . else Your opinion is the best for an AC motor

Ok,I support your opinion of 2 strings of 10,check the inverter or charge controller if it supports 500v or more

What is the minimum amps to charge a 48v system?

[@colcent_solar]

From 1-300amps depending on the battery bank it can be more The higher the current the faster the battery charges For eg 5amps can charge a 48v battery 5kwh - 10kwh but it may take 2days or more to full the battery 🤔
