Hi,

When I had my H1-6.0-E-G2 installed the datasheet showed a max input power of 9000W split 4500W per MPPT. I now see the new datasheet shows the same value but also has Max PV array power of 12000W. does this also apply to inverters before the new datasheet was published? Does the inverter just cap at 6kW total power? I'm looking at adding a second inverter when adding extra panels and splitting it between them but just wanted to know the limits of a single inverter.

Thanks

The inverter running latest firmware cannot handle more than 4,500 watts per string (or a maximum input current of 16A) whichever is met first - thereafter it will clip and derate the power to 4,500 watts per string.

It cannot handle arrays with more than 12,000 watts in other words you cannot over power the inputs too much or it will be unable to derate and the inverter will be damaged.

So in effect the main take away is make sure each string does not have more than 16A max input current and if it is over powered make sure the maximum array size is no more than 12kW but the inverter will clip each string to a maximum of 4,500 watts (9kW total).

As you have an H1-6 inverter the maximum AC output is 6kW so you could be feeding house load and exporting to a maximum of 6kW AC AND charging your batteries with the remaining 3kW.

But once your batteries are full the max output is 6kW and the arrays will be derated so that they do not generate any more than that.
