Mixing panels

To my understanding, all panels will then run as if they were all 460w panels (although 470s might offer slighly higher voltage). 

So definitely can do with a very slight loss (presuming of course the combined voltage fits the MPPT range max).

Would welcome some other expert input though 😉

On a HV input inverter this should really be no issue. Less than 1% loss at peak output. Although, if it's a 5kW Deye with a 13A limit on the input, oh horror, it may be a little more.

The 1st part is spot on. Due to the maximum current of 460/470W being around 10A make specific it will cause no horror on a Sunsynk with 13A allowed to each MPPT. 

The derating on amps hold true due to the lower amps of the 460W. The small higher volts of the 470W will be retained in the series string.
