array wiring , series or series parralel
I have an 18 panel 170 watt two string array should I series parralel wire this so I will have nominal voltage and higher current levels or just series wire the whole 18 panels? I have a sunny boy 2100 grid tied string inverter. It is operating close to its maximum 600 volt threshold but the array current is low in comparrison to the voltage. Currently both arrays are in series. My voltage drop under load is around 200 volts dc and output is around 700 watts average over a time period of 10 hours. production is around 7KW hours per day.
