5.7 MODULE TECHNOLOGY
SAJ grid - tie solar inverters provide the optimal solution for any module.
Transformerless-type SAJ grid-tie solar inverters are designed for ungrounded
modules, especially for the crystalline silicon photovoltaic modules, such as
monocrystalline silicon and polycrystalline silicon. While the thin-film
modules are not suitable for SAJ transformerless inverters.
5.8 POLLUTION DEGREE
SAJ grid-tie solar inverters comply with the pollution degree 3.
5.9 OVERVOLTAGE CATEGORY
Overvoltage category III applies to SAJ grid - tie solar inverter AC
terminals. For PV circuits in general, Overvoltage Category II is assumed.
