Fronius Reserva Pro
The Fronius Reserva Pro is a DC-coupled, high-voltage battery that pairs with Fronius GEN24 Plus inverters. It stores 11.9 kWh to 31.9 kWh in a single tower, so you can size it to your home or business without adding a second battery. DC coupling means your solar generation goes straight into the battery without an extra conversion step, so less of it is lost along the way.
The lithium iron phosphate cells are rated for indoor and protected outdoor installation. That suits Canberra, where winter nights regularly drop below zero and your battery needs to be ready for the next morning.
