Enphase Myth Busters – Micro Inverter systems are not battery ready

AC Coupling allows the use of Enphase Microinverters with off-grid and battery-based photovoltaic systems. These applications require a battery-based inverter to create a “microgrid” that the microinverters can then be connected to. This is generally referred to as AC coupling because the Enphase Microinverters and the battery-based inverters are “coupled” to their AC outputs.

These systems are no more complicated than a standard string inverter set-up and have the advantage of providing power during power outages, in emergency situations, and to remote locations. Enphase Microinverters, when AC coupled to a battery-based inverter system, offer advantages over other inverter technologies. This is because a microinverter system is divided into branch circuits to provide a tapered charge to the batteries. Offering more flexibility than string inverters, Enphase Microinverter systems can be AC coupled to a battery-based inverter system after installation, and the production capacity and critical loads can be increased or reconfigured to fit storage needs. Enphase Microinverters also offer the design flexibility, increased safety, and increased performance that come with module level maximum power point tracking and monitoring.
