AquaVolt — 5.12 kWh plug-in AC battery for homes
Country: China · Model: AquaVolt
This AC-coupled home battery stores 5.12 kWh and delivers 2.5–3.6 kW continuously, up to 4 kW in off-grid mode, through its built-in converter. It ties into an existing PV system on the AC side, including microinverter installations, and takes over backup supply for the house.

Description
Inside are LiFePO4 cells rated 100 Ah, and the 95% depth of discharge means nearly all of the 5.12 kWh is usable. Because the converter is integrated, the existing grid-tied inverter stays in place and the battery simply joins the AC line between the PV system and the distribution board. When the grid drops, loads move to the battery in 10 ms or less, fast enough for computers and boiler controls. The IP65 enclosure accepts mounting outdoors under a canopy, in a garage or in a utility room. At 560 × 650 × 185 mm and 65 kg, the unit needs a load-bearing wall or a place on the floor. Wi-Fi and Bluetooth handle monitoring, LAN is optional, and RS485 links the unit to external controls. Rated cycle life is at least 8,000 cycles.
How to choose
Power is the deciding spec here, since 3.6 kW continuous covers lighting, a refrigerator, a boiler and network gear but not an electric cooktop and water heater running together. If the house has no inverter yet and needs more capacity, the Cygni kit with an 8 or 10 kVA hybrid inverter and 7.68–46.08 kWh of storage is the better match. AquaVolt suits retrofits of a working PV system without rewiring.

FAQ
Can AquaVolt be added to a microinverter system?
Yes, the battery connects on the AC side and works with microinverters. It has its own converter, so the existing PV equipment stays as it is.
How much power does AquaVolt deliver during a grid outage?
Up to 4 kW in off-grid mode and 2.5–3.6 kW continuously in normal operation. Switchover to backup takes no more than 10 ms.
How much of the AquaVolt capacity is actually usable?
The maker states a 95% depth of discharge, so almost the full 5.12 kWh is available in each cycle.
Can AquaVolt be installed outdoors?
The IP65 rating permits outdoor placement, preferably under a canopy and out of direct sun. The unit weighs 65 kg, so the wall must carry that load.
What is the cycle life of the AquaVolt battery?
At least 8,000 charge and discharge cycles on 100 Ah LiFePO4 cells.
