5kW MPPT limited to 9.9A
I have a Deye 5kW inverter that seems to limit the MPPT current to 9.9A exactly despite the datasheet stating 11A. This is severely impacting the performance of my 450W panels which have max output at 10.8A. Can anyone confirm if this issue is also present in the Sunsynk-branded inverters or this is a design flaw? Or perhaps a firmware bug? If it's only the Deye, I'm thinking of swapping out my inverter for a Sunsynk rather.

yes, it is, I have six JaSolar 540 watt panels in series, the Impp is 12.94 amps, before buying the panels, i confirmed the new 13 amp rating with Sunsynk support, only requirement was upgrading the firmware to 31XX series
