Compare ‘DC Couple’ or ‘AC Couple’ for the Alpha ESS
If you already have a solar system in place, choosing to use AC coupling with the AlphaESS battery system is a practical option. Basically, it’s as simple as plugging the AlphaESS battery into your switchboard, just like any other household appliance.
The system then converts the AC energy from your solar panels into DC energy to store in the battery, and when you need it, it converts it back into AC to power your home. While this process is pretty straightforward, there is a small energy loss (around 3-4%) during these conversions.
However, if you’re starting fresh with a completely new setup, a DC-coupled AlphaESS battery is likely the better choice. In this case, you wouldn’t need to buy an extra grid-connected inverter, because the AlphaESS system can handle everything for you.
The DC coupling process is more efficient since it only converts DC to AC once, when the battery power is being used in your home—resulting in less energy loss and a smoother overall experience.
