Mixing 2 inverters in Parallel

I have just fitted a Fox AC1-3.7-E-G2-WL inverter and 2 x EP12 batteries but want more load capacity so am looking at adding a second inverter in Parallel. I can see my inverter has the Parallel connections and can get an H1-3.7-E-G2 3.7Kw but will the 2 link and work together or do they have to be the same models ?
Thanks in advance

Hi, did you get anywhere with this?
I've been told by national grid that I have a site limited for export but have 3 mppts so was planning a 5kw (with 2 strings and battery) and a 3kw (with PV input only)

Hi, yes I was told similar. The limit is 3.6Kw for a single inverter on G98. I have added a second inverter in parallel and its doing exactly what I want it to. I can now load up to 7.2Kw and charge at 3.6Kw per battery (7.2Kw total charge) I have 2 AC1-3.7-E-G2-WL inverters with 1 EP2 battery on each set up in parallel. Working very well !
