March 13, 20233 yr Hi, can anyone please tell me if I can run 4 x 460watt panels with 2 x 470 watt in series
March 13, 20233 yr Do you have the datasheet for both? If so, compare the values and if they are within a couple of percent it should not be an issue.
March 13, 20233 yr My understanding: in series, the entire series will run at the amps of the lowest rated panel. So effectively, presuming similar specs, your 470w panels will be "de-rated" to 460w, no other issue. But as previous poster pointed out, compare the spec sheets, specifically the amp ratings.
March 14, 20233 yr Author Hi Marcus, thanks for your reply, the 470watt MPC (IMP) is 13.41Amp and the 460 Watt is 13.13amp
March 14, 20233 yr 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 😉 Edited March 14, 20233 yr by markus_m2

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.

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.
