SMA skriver så här under “7 Reasons Why You Should Oversize Your PV Array” från 2015, https://www.sma-sunny.com/en/7-reasons-why-you-should-oversize-your-pv-array-2/. De skriver visserligen “This post was originally published in 2015. The tips and techniques explained may be outdated.” men misstänker att nedanstående varning gäller. Svarar inte specifikt på din fråga men indikerar att det är olämpligt att försöka.
“The most important input characteristic which should NEVER be exceeded for any SMA inverter is the input voltage limit. Inverters and their constituent components are designed and rated for certain input voltage levels. If an input voltage were to exceed this rating, it will almost certainly result in the inverter’s immediate failure. When oversizing a PV array, it is important to never exceed an inverter’s maximum input voltage. Consideration should also be given to the maximum power point tracker’s operating voltage range, to make sure that the PV array will not go outside that range. When a PV array voltage is outside an MPPT voltage range, the inverter is not able to maximise the performance of the system.
To most easily design an oversized PV array, Sunny Design is the simplest tool since it can provide warnings if a design will exceed an inverter’s critical input parameters.”
