can be oversized above the rated nameplate capacity without voiding the manufacturer’s warranty, provided that
the following conditions are always adhered to:
The string and array configuration do not exceed the sizing limits of the inverter (Isc_max, Ppv_max, Udc_max)
stated in the official datasheets and in this document. This includes, but is not limited to conditions like, low
temperatures, high irradiances, bifacial gain, etc.
Exceeding any of these limits can damage the inverter or even cause harm or injury.
