SolarEdge S440-1DM4MRM power optimizer 440W for 1 photovoltaic module
The SolarEdge S440-1DM4MRM power optimizer works on one module and tracks its maximum power point independently of the others: a shaded roof plane, a dirty panel or a manufacturing tolerance no longer penalises the whole string.
It is part of the SolarEdge system: together with the inverter it provides module-level shutdown, with the voltage dropping to 1V per optimizer when the grid is lost, protecting installers and firefighters. Maximum efficiency 99.5 %, MC4 connectors, IP68 rating and a 25-year warranty.
Key strengths
Every module at its bestIndependent MPPT per module: shade and dirt do not drag the string down.
99.5 % efficiencyMinimal conversion losses along the DC path.
Module-level shutdownWith no grid the voltage drops to 1V per optimizer.
Bifacial compatibleDesigned for high-current modules as well.
Strings of different lengthsAllows roof planes with different orientations and module counts.
25-year warrantyThe same expected life as the PV system.
