The Dyness AquaVolt is an AC-coupled home energy storage system with LiFePO4 cells and 5.12 kWh of nominal energy. It can be added to an existing photovoltaic system and works with 99% of PV inverters and microinverters. It has a plug-in output for essential household devices and, when the grid is down, switches to emergency power within 10 ms. Management relies on a P1 meter, an IR Reader or a smart meter, and includes scheduling by time-of-use periods and dynamic tariffs. Installation is plug and play, suited also to those who do it themselves. Protection is IP65 and communication runs over Wi-Fi, Bluetooth, LAN and RS485. Service life is at least 8000 cycles.
Highest technical score among the 5 sheets in the AC-coupled, no panels category (room-sized tier): 75/100.
