How to get high voltage, high current output of solar cells
A reasonable series of parallel can be, and increase the number of sub-batteries
Using 880 0.5 volt 5 amp output of the panel, 440 in series as the first group, and then get a second group, then the two groups in parallel, you can get 220 volts 10 amps output
Series can increase the output voltage, parallel can provide output current. Using a series parallel method to achieve, for example: need 220 volts 10 amps.
