I added three 400 Watt panels to the other MPPT controller on my SolArk 12k and am getting some odd results. The voltage stays fairly constand at 130-131 volts but the current climbs until about Noon then drops from 2.5 Amps to zero current then picks up again at about 4PM but never exceeds half an Amp. I know I am close to the minimium start up voltage of 125 volts for the MPPT controller according to the specs. The other thing is that the operating range of the MPPT according to the specs is 150-400 volts. It is also 98 F today.
The STC Vpmax is 36.05 and Voc is 43.02. The number I am seeing is more consistent with the Voc figures.
I originally purchased and planned on four panels but reduced that to three and may have cut that too close in terms of Voltage. I may have to install that other panel.
