Excellent grid compatibility
Output current quality in low irradiation condition
PR control is performed in closed loop in the static
coordinating, not relying on the grid phase angle,
and will not be influenced by grid fluctuation. By
using the PR controller, under 20% loading, the
output current harmonic will be decreased from
2.8% to 2.28%

Good heat dissipation design, up to 120% overload capability
• Good heat dissipation design: the air flows into the inverter from the frontside and flows out
of the inverter from the backside. The inverter can be installed against the wall, to reduce the
length of the air duct and increase the heat dissipation efficiency
• Strong overload capability: up to 120% overload capability can be achieved under 50℃; while
derate according to the curve above 50℃
