How to choose a photovoltaic inverter?

The inverter generally chooses an outdoor type, adopts a natural cooling method, has a high protection level of the shell (usually up to IP65),  requires little environmental modification for installation, and the cost is low. The impact of the noise generated by the operation of the inverter on the user will also be greatly reduced, but good equipment protection is required.

Generally, the inverter of the corresponding power segment is configured according to the requirements of the system. The power of the selected inverter should match the maximum power of the photovoltaic cell array. Generally, the rated output power of the photovoltaic inverter is selected to be close to the total input power, (usually exceeding The configuration is controlled within 1.3), which can save costs.

On the other hand, the selection of inverter capacity can be optimized according to the installation conditions. If the installation site is not clear at the early stage of the design, and the installation site is not fully considered, it is necessary to choose a low-power photovoltaic inverter as much as possible to realize multi-channel independent power tracking. If necessary, select a micro-inverter to achieve the maximum power of a smaller unit. Tracking, so as to protect the series-parallel mismatch and other problems caused by the venue not being large enough or not regular enough in the later stage.
