FAQ
Q1、How to choose the right capacity of PV step-up transformer?
A1：It should be matched with the inverter capacity, considering system efficiency, loss, and future expansion, usually selected according to 1.0–1.2 times of the total inverter power.
Q2、What are the advantages of photovoltaic prefabricated cabins?
A2：They feature factory prefabrication, short installation period, high integration, good protection, strong weather resistance, and are suitable for outdoor photovoltaic projects.
Q3、What’s the difference between a power transformer and a PV step-up transformer?
A3：A power transformer is for general power transmission. A PV step-up transformer is optimized for photovoltaic inverter output, with better adaptability to harmonics and fluctuations.
Q4、What is the function of a PV grid-connected cabinet?
A4：It realizes grid-connected control, protection, metering, switching, and safety interlock to ensure stable and compliant connection between the PV system and the power grid.
