Solar's basic dilemma, solved.

Like bread and butter, black and white, sun and sand -- solar and storage are a perfect pair. Storage addresses a fundamental problem of solar energy: while solar production peaks during midday, energy consumption is highest in the morning and evening. With storage, you can save the energy you produce for when you need it most.

Storage systems come in two varieties: AC-coupled or DC-coupled. AC-coupled systems connect to a solar array on the AC side, while DC-coupled systems connect on the DC side. The most obvious advantage of DC-coupled systems is that they allow both the solar array and battery to be served by a single inverter. AC-coupled systems offer equivalent efficiency to DC-coupled systems with advantages in flexibility, reliability, and safety. The Enphase AC battery is an example of an AC-coupled system, while Tesla’s Powerwall is an example of a DC-coupled system.

AC-coupled system advantages

  • Minimises high-voltage DC indoors

  • Solution can be retrofitted to existing solar installations

  • More incrementally scalable

DC-coupled system advantages

  • One inverter handles all conversion for PV and batteries.

  • Equivalent efficiency to AC-coupled systems
