● Natural heat convection, no need of external fans
● 5 years standard warranty, 25 years extension warranty


In the string system, the PV modules are connected in series to form a PV string, and the single or two parallel PV strings pass through the independent DC/DC DC boost converters inside the string inverter, and then share the string inverter. The same set of inverter circuits inside the device realizes grid-connected power generation. Therefore, this string system architecture has multiple MPPT functions. This kind of system generally has two-stage power conversion structure of DC boost and AC inverter. When the input voltage is low, the DC boost converter will work and complete the MPPT function. When the input voltage is high, the MPPT function is realized by AC inverter. . Group-type inverters are widely used in distributed photovoltaics. They are generally installed in industrial and commercial or domestic roofs, and can also be installed in agricultural greenhouses, fishing ponds, and barren hills. The household roof is distributed using a single-phase grid-connected inverter, and the power section is generally from 1.6 to 5 kW. Other medium and large power applications use three-phase grid-connected inverters, and the power section generally ranges from 5 to 60 kW.
