SolarEdge optimizers track Maximum Power Point (MPP) at the module-level and thus mitigate shading losses occurring with string or central MPP tracking. In addition, as opposed to micro inverters, power optimizers can track a module’s MPP at voltages as low as 5 volts, a specification allowing SolarEdge to optimize module performance even under severe shading conditions.
SolarEdge Power Optimizers perform solar module-level MPPT and are typically fed into a central SolarEdge SE Series grid-tie inverter on a single string of modules. The parallel design of the optimizers allow for a fixed low voltage, regardless of the string length. The power optimizers work in conjunction with the inverter to allow module-level monitoring and fault detection on the SolarEdge web portal.
