The Chinese manufacturer said its new three residential battery lines support 90% depth of discharge and deliver more than 6,000 cycles.
Chinese manufacturer Solis has announced the launch of a range of residential energy storage systems.
The launch, introduced under the SolisStorage brand, marks a shift in the company’s focus from manufacturing inverters to becoming a more comprehensive supplier of energy storage systems.
“All batteries are built with long-lasting LiFePO₄ chemistry, support depth of discharge of 90% or more, deliver more than 6,000 cycles and are designed to maintain reliable performance for up to 10 years,” the company said in a statement. “Natural cooling, CAN/RS485 communication protocols and the ability to connect multiple units in parallel ensure maximum flexibility, safety and sustainability.”
The new portfolio includes three series.
The low-voltage IntelliHome is a wall- and floor-mounted storage system with capacities from 5-16 kWh, available in IP20 or IP66 protection classes, for indoor and outdoor use. It is offered in three storage capacities – 5.1 kWh, 10.2 kWh and 16 kWh – and targets home solar-plus-storage applications looking for backup power and improved self-consumption.
The smallest model in the series offers 5.1 kWh nominal and usable capacity with a nominal cell capacity of 100 Ah and a recommended charge and discharge current of 50 A. The mid-range version delivers 10.2 kWh with a recommended current of 100 A, while the largest unit offers 16 kWh of storage capacity and a recommended current of 157 A.
The batteries are based on lithium iron phosphate (LFP) chemistry and operate at a nominal voltage range of 44.8 V to 57.6 V. According to the manufacturer, each battery pack integrates an intelligent battery management system (BMS) that manages charging, discharging and safety functions. All variants use LFP cells
The FlexHome series is a stackable low-voltage system with IP66 protection, with capacities ranging from 5 to 40 kWh. It operates within a voltage range of 44.8 V to 57.6 V, which puts it in the low-voltage residential storage segment.
The system is available in eight capacity variants, increasing in steps of approximately 5 kWh. The smallest model offers 5.1 kWh of nominal and usable capacity with a nominal cell capacity of 100 Ah and a recommended charge/discharge current of 50 A. At the top end, the largest model offers 40.8 kWh with a cell capacity of 800 Ah and a recommended current of up to 320 A. Intermediate models are offered with 10.2 kWh, 15.3 kWh, 20.4 kWh, 25.5 kWh, 30.6 kWh and 35.7 kWh.
Finally, the FlexAIO is a high-voltage all-in-one stackable system with capacities of 15-40 kWh.
All three battery series are suitable for up to 8,000 charging cycles at a depth of discharge of 90% and are designed for a service life of approximately 10 years. Each battery module functions independently and integrates a battery management system (BMS) designed to manage charging, discharging and system protection.
“This launch isn’t just about adding a battery to our portfolio. It’s about completing the ecosystem,” said Jimmy Wang, president of Solis and SolisStorage. “With batteries, hybrid inverters and intelligent AI energy management through SolisCloud, we can now deliver a truly integrated and complete residential solution. We listened carefully to installers around the world, they wanted reliability, flexibility and simplicity – that’s exactly what we delivered.”
