I don´t think so.Mistreating it like this allows me to utilize all functions, and sell to the grid the surplus energy.
I guess you don´t understand how MPPT works.What I was thinking now is a DC power supply of 250v DC with input connected to the generator (230v AC) and output to the MPPT (250v DC) at 12a / 3000W
Well - that is the main reason for posting in a forum with knowledgable people...Hi,
I guess you don´t understand how MPPT works.
--> the MPPT will not work with a constant voltage (low impedance)

How would you synchronize the Diesel AC voltage to the grid, even if you could?
Correct, that is my main concern now - what happens to the surplus power from the DC powersupply in case of a grid fallout / islanding situation.The grid tied inverter should meet local standards requirements for disconnection when the real mains fails - this is the main safety issue.
As to powering it off a stiff voltage source such as a charger - at 250VDC in this case - it will work ( the MPPT ) but will sit at full power, until the Vout from the charger sags a bit.
If you can obtain a charger with a controllable Imax out ( i.e. a current limit, ideally a slightly soft current limit ) then the MPPT in the GT inverter may, stress may, settle at the Imax point - so you can control the power to the grid by adjusting the Imax out of the charger.
Best of luck.
No. The current is not constant. Just the voltage could be seen as almost constant.given situation as I will be feeding a constant voltage and current.
So let´s say 230V and the generator´s internal impedance is 1Ohm. Then the MPPT point is when load also is 1 Ohms.What I am hoping will happen is that it finds the "Maximum power point"
Indeed I more talked about about the rectified AC of the generator.but is the DC power supply taken into account?
