PV throttling on heavy load
We have an 8kw inverter with 16x 540w panels (8 per MPPT), when our total load reaches around +- 6kw the PV / MPPT seems to be throttling quite badly.
At first we thought this was a temperature issue, but after installing an aircon and adding a desk fan, we had little to no improvement.
The PV delivers max power when charging the batteries, and will stay at max power until full, but it doesn't like heavy loads.
When a load gets added that will exceed +- 6kw total load, it will instantly throttle. Is anyone experiencing anything similar? Or could this be an firmware issue?

Just some feedback regarding this issue: After requesting a firmware upgrade, the inverter is working 100% again.
