Forgive my ignorance but, If you want the 600 watts, don’t you need to connect the panels in parallel? Otherwise you would increase the voltage not the wattage is that correct? Thanks.

Yes you would be correct if the panels all matched in voltage, but in this case the 50 watt panels operate at 19 Volts and the 250 watt operate at 24 Volts. If they were connected in parallel the 250 watt panels would operate at 19 Volts losing wattage. Which is why I have to run each set to a different charge controller to get the full wattage. In the end calculation, wattage is still the same whether its connected in series or parallel. Watts = Volts x Amps.

Did you connect the panels and series or in parallel? If you put them on the series that 90 V right? That would be the most efficient hook up.
