The Chinese company said its modular system supports up to 64 kWh of storage, multiple PV inputs and 0 ms backup switching for uninterrupted operation.
Chinese energy storage solutions provider Hoymiles has released its first all-in-one battery energy storage system (BESS).
The residential system, called HiOne, combines an inverter, batteries and an energy management system (EMS) in a single housing.
“We have included advanced AI-based time-of-use (AI-TOU) functionality in HiOne, allowing for up to eight customizable time segments,” the company said in a statement. “By dynamically understanding electricity price patterns, users’ consumption habits and renewable energy forecasts, the system automatically plans charging and discharging strategies, increasing self-consumption and maximizing bill savings.”
HiOne is based on a range of inverters with AC powers of 8 kW, 10 kW, 12 kW, 16 kW and 20 kW, supporting maximum PV inputs of 16 kW, 20 kW, 24 kW, 32 kW and 40 kW respectively. The two smallest inverters have three MPPTs with three input strings each, while the larger models have four MPPTs with four input strings. The maximum efficiency reaches 98.5%, with an EU efficiency of 98%.
The system includes the company’s own lithium iron phosphate battery (LiFePO₄) of 8 kWh, good for 8,000 cycles. A maximum of eight battery packs can be connected per inverter, allowing for a maximum parallel capacity of 64 kWh. Built-in DC-DC converters and automatic state-of-charge (SOC) balancing allow users to seamlessly combine new and old batteries.
All inverters measure 620mm x 360mm x 255mm and weigh 31kg, while a single battery pack measures 620mm x 360mm x 255mm and weighs 67kg. Both the inverter and the battery packs have an IP66 protection rating and can operate at altitudes up to 4,000 m and humidity up to 95%. The inverter operates between –30 C and 65 C, while batteries have a storage temperature range of –25 C to 60 C.
“HiOne features 0ms backup circuitry, creating a transition so seamless that even heavy inductive loads, such as air conditioners and washing machines, continue to operate without flicker during a power outage,” the company said. “All wiring is neatly hidden behind a sleek side grille, giving the system a sleek, furniture-worthy aesthetic.”
