If you already have a solar system in place, AC coupling an AlphaESS system is the logical choice. This means that the AlphaESS battery system plugs in to your switchboard like any other appliance and converts AC energy back to DC energy to store in the battery and converts it back from DC to AC when it is time to be used. There is some small (3-4%) inefficiency here as power is lost through the extra conversions. NOTE: Single Phase only
If you were starting from scratch and installing a new solar system, a DC coupled AlphaESS battery would make the most sense. This is because there would be no need to purchase an additional grid-connected inverter as the AlphaESS unit can do it all for you. It also only converts DC energy to AC energy once when the house is drawing down power from battery – meaning its a more efficient solution. NOTE: Single Phase Only.
