Sorry, I’m jumping in on this conversation…
We were looking 20x Jinko 370w panels to a SMA SunnyBoy 5.0 - located in New Zealand so don’t have the regulations you guys have with panels to inverters ratios etc. also don’t have as much sun to play with either… hence looking for the additional panels to increase shoulder input.
Confusingly, the 7.2kW array does limit the choice of inverter, where the array size exceeds the input of inverters like Sungrow - even tho it’s within the maximum voltage range…
However, I’m struggling to work out if the SunnyBoy 5.0 is a 5kW or a 4.6kW inverter. The spec sheet seems to imply both.
We reached out to SMA for there input, but the reply was:
The unit is designed to work at 97% of its capacity, you won’t get 100% due to factory reasons.
That results in 4.85kW, however I do wonder if he was meaning the unit is 97% efficient?
Interesting in your insights to this.
