This series is a three-phase grid-tied PV string inverter (transformer less) that converts the DC power generated by PV strings into AC power and feeds the power into power grid.
Flexible Design: Small size, light weight, support manual installation, reduce user installation and maintenance cost.
Efficient Conversion: Transformerless, Max.efficiency is up to 99%; Euro. efficiency is up to 98.5% , Total current THD <2%.
Grid Friendly: Active and passive, Anti-islanding protection, Continuously adjustable, Active power (0-100%) function.
Excellent Qualities: CQC Gold Sun Certification, TUV Certification, SAA Certification, CE Certification.
