sonnen eco: The Complete Battery Review | EnergySage

The sonnen eco is an AC-coupled battery; this means that in a solar plus storage system, direct current (DC) electricity flows from solar panels to a solar inverter that transforms the electricity into alternating current (AC) electricity. That AC electricity can then flow to your home appliances or go to another inverter that transforms the ...

Your guide to AC

The inverter converts the energy just once, from DC to AC, as it flows from the battery to your home appliances. That leads to less electrical loss than with AC-coupled systems; DC-coupled systems are approximately 4-6% more efficient than their AC-coupled counterparts. Lopez points to increased efficiency as the main draw for DC-coupled …
