Conow Atlas 6000 AC: 6 kWh plug-in home battery for Germany
Conow, a residential storage brand backed by Tuya Smart, has introduced the Atlas 6000 AC home battery in Germany. The system is aimed at households that already have rooftop solar and want to add storage without replacing an existing string inverter, as well as at users who want to take advantage of dynamic electricity tariffs.
Capacity and electrical design
The Atlas 6000 AC stores 6.28 kWh using lithium iron phosphate cells and includes an integrated 3 kW bidirectional AC inverter. It is AC-coupled, so it works alongside existing solar inverters rather than replacing them. The unit measures 805 mm x 315 mm x 256 mm and weighs 55.9 kg. It is fanless and rated IP65 for outdoor installation, with an operating range of -20 C to 50 C. An internal heating film helps in cold weather, though the article notes this comes at the expense of efficiency.
Installation and scalability
Out of the box, the battery connects to a standard German Schuko socket or normal outlet. In plug-in mode, grid feed-in is limited to the 800 W regulatory threshold for plug-in storage, while charging can reach up to 3 kW. Full 3 kW discharge requires hardwiring by an electrician. Up to 10 units can be linked wirelessly for 60 kWh of capacity, or three units can be combined into a 9 kW/18 kWh three-phase setup.
Performance and safety
Conow claims a round-trip efficiency of 87.2% and rates the cells for 10,000 cycles. The system carries a 10-year warranty. Safety features include thermal isolation between the inverter and battery pack and an internal aerosol fire-suppression module.
Software and compatibility
The system runs on Tuya's backend, and Conow presents third-party compatibility as a key advantage. The software is described as connecting with existing inverters from SMA, Fronius and FoxESS, optical smart-meter readers, and compatible heat pumps and EV chargers. The article cautions that firm connectivity will depend on exact details.
Availability and pricing
The Atlas 6000 AC is available through German online distributors including Tepto, Sonnenmatrix and Solfuerza, priced between €1,239 and €1,299 at 0% VAT under Germany's residential solar tax exemption. The article does not disclose a launch date, US pricing, or detailed warranty terms beyond the 10-year period.
