SolarEdge S440 Power Optimizer (SKU Part Number S440-1GM4MRM)

The SolarEdge Power Optimizer is a device that attaches directly to your solar module and uses MPPT technology to optimize the DC power before sending it to the inverter. The Power Optimizer is very similar to a microinverter. However, the Power Optimizers do not actually invert the DC power to AC power. The optimizers allow you to see system performance and diagnostics at the module level, similar to a microinverter, yet they last much longer due to the type of electronics used in the device. Microinverters have a much shorter lifespan vs a power optimizer. The SolarEdge optimizers come with a 25 year warranty, which means it's not too likely that you will ever have to service any of the devices once they're installed. Unlike a microinverter system, the Power Optimizers feed DC energy into a specifically designed inverter that maximizes the efficiency and output of the solar array.
