I returned my Kodak to the distributor, and it was sent back to the supplier, they tested it and confirmed a hardware issue if that helps. I have have yet to install it again, not sure that I will, it's a backup for now. Just to be clear I made sure that the device was only producing 50% of its PV capacity, it was not a 'reporting', 'calculation' or 'indication' issue.

Hi Guys, Just a quick update from my side. I have had zero joy with the distributors of Kodak, Blue Mountain Energy, no info, help or feedback, they only answer phones when they feel like it and have zero customer service. Will be returning the inverter to where I bought it, Communica, they say it must be sent back for testing... blah blah blah. @BritishRacingGreen helped getting my old RCT going again, he is an absolute legend. See attached the difference after I swopped them back.

Sorry yes you are correct. It is not a clone.

The plus spec allows for parallel operation, thought id pay the extra R1200 for the possible upgrade path. Will be having the RCT inverter serviced and will probably just put that back. I got the Kodak installed 12 days after purchase, and noticed the issues 13 days after, had I gotten it all done within 7 days I could have just returned the Kodak inverter for credit and take another model.

The issue is independent of load. Starting the borehole(0.75kw but pulling 1.1kw) or booster-pump(0.25kw pulling 0.38kw) simply pulls the excess watts from the battery. I even tried 3S, for a dead middle of the MPPT range 90VDC, only 50%. Connect the RCT 5KW and I get 100%, plug in the Kodak 50%... gotta be a hardware/software issue with at least a few units, I am not the only one. I am using a Narada battery, on USE settings, I use the RS485 on the battery for my ICC connection, I am not even sure the Narada could talk to the inverter nor do I really see a need to.

I have the Kodak OG 5.48+ (The plus model has a MPPT of 60~115VDC)

I have the same issue. Off-grid setup. 1x Kodak 5.48 OG plus (Axpert King clone) FW 72.00 4x Trina Solar 330W 2S2P = 1320W My old RCT 5kw inverter gives ~1200W, MPPT ~64V ~18.75A New Kodak OG plus ~600W, MPPT ~63V ~10A Changing the solar string to 3S: My old RCT 5kw inverter gives ~830W, MPPT ~96V ~9A New Kodak OG plus ~400W, MPPT ~96V ~4.5A The conclusion is inescapable, the new inverter only delivers 50%. I have contacted the distributors Blue Mountain Energy, have yet to be advised further.
