SPF 3000TL HVM24 MPPT problem?

[Robert]

I have SPF3000TL HVM24 , FW version FV503,08/014.05/null.
On the roof I have 6 pieces of solar panels with a power of 430W, which amounts to 2580W of installed PV power. On an MPPT inverter, it never reaches more than 1250W charging power . I tried all the possible ways in the parameters of the inverter. I have set the maximum charging currents but there is no change. The maximum charging current I achieved is somewhere around 40A. What’s wrong?
