I have two schneider XW+ 6848 inverters, and have sell to grid enabled on both. However, the numbers on the attached screenshot don't add up, i.e., sell to grid + load is about 1.5kW more than solar production. I know for sure the load number of 2.7kW is wrong because I turned off most of the appliances in the house, and the correct number is less than 800W, then the numbers will add up.
  1. Why the load number is wrong
  2. If I still want to sell to grid, should I do it on both inverters, or just one of them?

    I got a pair of these xw 6848 pro units. Selling to grid. Can't get them over 6 kw. Each one does 3025 watts. When I look at the settings on Insight Home I see 20 amps sell max on each one. But when I try to modify that I get a red box blocking me. Only when I try 12 amps does it light up green. Doing the math the 3000 watts IS 12 amps on the AC side. What is limiting me. I used to be able to push 10 kw, now just 6 kw !!! Seems to be out of my control as in 'Grid Codes' software.
