The MPP-current values (STC and NOCT) of PV modules are increasing in conjunction with higher module nominal power. Huawei Technologies, as a manufacturer of Photovoltaic Inverters, hereby confirms that the below listed Huawei inverters will meet the following conditions, while all the installation, commissioning and maintenance should be strictly abided in the user manuals of the corresponding products:
The max. current per single Input (A) listed above and shown in the datasheet and user manual of the inverter, is the current that the inverter can process on the DC side. This value is not a safety- and warranty-relevant specification. This information shows the capacity of the inverter on the DC Input that limits the current of the connected PV module string to this maximum value.
The max. short circuit current per single input or MPPT (A) listed above and shown in the datasheet and user manual of the inverter, is the limit to ensure electrical safety and maintain the validity of the inverter warranty. The specified value shall be strictly observed. The short circuit current of the connected PV module string shall be lower than the value from the inverter.
