Note: No grid export and no net metering - the datasheet has no grid-output or feed-in section, and certification stops at IEC62109 and IEC61683 without the IEC62116 anti-islanding and IEC61727 grid-connection standards a net-metered unit needs. It runs the load from PV and battery and takes utility or generator as a backup charging source. The Pro is a different machine on the DC side despite sharing the 3 kW output and the chassis of the standard IPV-3K24U. It takes 4500 W of array against 1500 W - a 500 V ceiling and a 70-425 V MPPT window instead of 145 V and 30-120 V - so it runs proper high-voltage strings rather than a short low-voltage one. Input current drops to 18 A because the voltage does the work. Output side is identical: 3000 W rated, 3600 VA apparent, 6000 W surge for 2 s. Overload is quoted differently as 150% for 2 s and 105-150% for 10 s. Same 24 V bank at 60 A solar, 120 A mains, 125 A discharge. IP54, 6 kg. The datasheet publishes MPPT tracking efficiency and battery-mode conversion efficiency but no PV-to-AC conversion figure, so the efficiency field is left empty rather than filled with a number that measures something else.
