Slightly less efficient than their DC counterparts they do have other advantages. Off Grid AC Coupled Systems have cost efficiencies at scale and are more effective at powering high AC loads throughout the day.
Generally used for larger scale off grid systems they use a string inverter alongside a hybrid or multi mode inverter. These are typically easier to set up with the potential to be expanded using multiple solar inverters to become micro grids.
Historically used in larger off grid systems, advancements in technology in recent years has seen a new evolution in battery storage with AC Coupled Batteries used in many grid connected homes. This technology allows those with existing solar the opportunity to retro fit an AC coupled battery alongside their new or existing Solar.
Don’t be fooled though. They are both AC but designed for very different purposes. On grid, rather than off grid, AC coupled batteries of this type are not typically powerful enough for off grid applications or to run a home in its entirety. Some may even struggle to handle multiple appliances so thorough research is always recommended. However, as they are smaller and compact in design, Systems tend to be modular and very easy to expand if storage needs grow.

Soltaro offer both AC or DC Coupled systems to suit your needs – Find out more by visiting our products page.
We dare to be different!
In addition to utilizing a PV-Battery DC charger, the AIO2 is also able to be AC coupled to existing solar. This means that the battery can be charged, not only from your new Soltaro solar system, but also from any excess power generated from your existing solar system.
Don’t forget to register your new Soltaro purchase to validate and extend your warranty.
