In my solar system, I connected 3 12v 165W panels in series. I also connected the panels connected in series with the same value in parallel. In summary, I have a battery charging power of 6x165 watts with a total battery charge of 990W. I have a 100/30 Mppt Smart charge controller. My battery is 12Volt 400 Ah lifepo4. At noon, I get Max 420 Watts of power on my Maximum mppt device. My panel direction, angle and outside temperature are at the required values. Why can't I get 800-900 Watts of power? What is the reason ? How should I connect the panels? Could I have a mistake?
My inverter is 12 Volt 1200 Watt Phonex.
