Unparalleled safety: Unlike string solar systems where there is extremely high DC voltage in the solar array, modules are connected in parallel in microinverter systems and each only carries a voltage of 40 V, significantly downgrading the safety risk in the first place. As a result, the microinverter system naturally meets rapid shutdown requirements, and ESTAR microinverters are compliant with such requirements as specified in EN 50549-1:2019, VDEAR-N 4105:2018, NF EN 50549-1/-10.
