Yes indeed the charge controller is a Chinese PWM high voltage unit.
I'm looking at this as the day is very overcast and still making 1200watts. Our single Geothermal H/P doesn't draw much more and for the most of the winter it provides 90% of the heat and the second unit will provide the balance on those snapping cold days.
The duty cycle for the one unit is approx. 30 - 60% on most days.
This is just back of the napkin calculations and is looking extremely interesting.
Looking forward to the new inverter and even more to see how much of our own power we can use.
