One part power electronics and one part networking and communications technology, microinverters and DC optimizers (commonly referred to as module-level power electronics, or MLPEs) are playing an increasingly significant role in large-scale and distributed renewable electricity generation. With the potential to improve the grid’s reliability and increase the overall energyRead More

The combiner box of today does more than just hold wires and fuses. Most solar product names are self-explanatory — an inverter inverts, a tracking system tracks, an optimizer optimizes. And even though a combiner box falls in this self-explained category (because, after all, its main job is to combineRead More
