Frequently Asked Questions

1.What scenarios are the string photovoltaic inverters suitable for?

String inverters are widely used in distributed photovoltaics. They are generally installed on industrial and commercial or household roofs, and can also be installed in agricultural greenhouses, fishing ponds, water surfaces, barren hills and slopes.Single-phase grid-connected inverters are used for distributed home roofs, and three-phase grid-connected inverters are used for other medium and high-power applications.

2.What are the advantages of string inverters?

The string type can occupy a place in the market thanks to the following advantages: easy installation, wall-mounted type does not take up space, especially suitable for small and medium-sized distributed photovoltaic application scenarios; flexible technology, the number of MPPT channels can be as many as 4, The component access scheme is flexible and suitable for various component installation orientations; the maximum efficiency tracking range is wide, and the power generation capacity is increased; the maintenance is simple, and the equipment maintenance is replaced by the whole machine, without the maintenance of professional technicians.
