I have a Sol-Ark 15K with 2 strings of 8 panels each of this panel in the 395 watt model (Vmp 30.84 V, Imp 12.81 A) run in parallel to MPPT #2.
The Sol-Ark shows a lower voltage (200 - 210 V) than the optimum in the spec sheet (246.72 V for 8 panels), and the current is flat lining at the Sol-Ark max per MPPT (26 A).

The MPPT is only hitting 5.8 kW, so in theory there's a little room to grow (up to 6.3 kW according to the panel specs, just shy of the Sol-Ark 6.5 kW limit per MPPT).

Is there some way to optimize this further? Or is it already doing the best it can with the PV modules and the environmental conditions at the time (it does get warm here in the afternoon - nearly 90 F presently). The other MPPTs are already in use, otherwise I would split up the strings.
