September 16, 2026 — Responding to diverse needs in Europe’s residential PV market, OneHo today officially launched two new Plug-In Battery: Solar Arc P2700 Pro and Solar Arc P2700 Pro AC. The new products target households installing PV for the first time and those upgrading existing PV systems, respectively. They address key pain points such as low surplus PV utilization, high retrofit costs, and complex installation and commissioning, helping users increase PV self-consumption and household energy returns while ensuring easy installation and emergency backup power.
Solar Arc P2700 Pro: High-Power PV Input, Higher Household Energy Returns
Designed for new PV installations, Solar Arc P2700 Pro features four independent MPPTs and connects directly to PV modules, reducing system configuration and installation complexity. Each channel supports up to 1,100 W PV input and is compatible with mainstream 400–700 W high-power modules. The four MPPTs independently track and optimize each PV input, maintaining higher generation efficiency even when modules face different directions. This enables flexible deployment on balconies, apartments, or rooftops with complex orientations, meeting diverse household PV needs.
With industry-leading 4,400 W PV input, the system captures more solar energy during the day and stores more green power during limited sunlight hours, further raising self-consumption and household energy returns.
Its scalable 2.6–15.6 kWh storage capacity can be flexibly configured to household electricity needs, accommodating changing energy demands at different stages.
Solar Arc P2700 Pro AC: Plug-and-Play, Easy Storage Upgrade
For existing PV households seeking storage upgrades, Solar Arc P2700 Pro AC integrates seamlessly with existing PV systems, adding plug-in battery on the AC side without changing the original setup. This true plug-and-play design eliminates complex wiring, significantly reduces installation time, and enables a faster, simpler setup.
Up to 2,500 W bidirectional AC power and 3,450 W peak output power enable more efficient energy storage and Delivery and support more high-power appliances, delivering stable, reliable power for daily energy scheduling and emergency backup.
3rd Gen WBG Power Semiconductors (SiC & GaN): Higher Conversion Efficiency, Lower Energy Loss
For core power devices, the Solar Arc P2700 Pro series adopts 3rd Gen WBG Power Semiconductors (SiC & GaN). Compared with conventional Si MOS designs, the system efficiency ceiling is raised to 91%; each 1% gain can reduce energy loss by about 50%, significantly improving energy conversion among PV, battery, and AC loads. It also reduces heat generation, ensuring stable output under high-power and long-duration operation, and delivers more power in the same compact design. Superior thermal performance also eliminates the need for fan cooling, enabling silent, maintenance-free operation for a quieter and more reliable home energy storage experience.
Long-Lasting Reliability for Household Energy
Solar Arc P2700 series uses LFP cells with up to 8,000 cycles—about 33% more than the industry mainstream of around 6,000 cycles—significantly extending system lifespan and delivering lasting storage value. It features a cell-level intelligent BMS and multi-layered safety protections for real-time battery monitoring and comprehensive protection. Built-in low-temperature heating ensures stable operation at -20°C for reliable winter use.
Intelligent Scheduling, Holistic Energy Optimization
The Solar Arc P2700 Pro series also the OneHo Omni AI Agent. By combining weather forecasts, PV generation, household energy consumption, dynamic electricity tariffs, and other real-time data, it continuously optimizes charging and discharging strategies for smarter, more efficient home energy management.
Open Ecosystem for Smart Energy
To enable a smarter home energy management experience, Solar Arc P2700 Pro series is compatible with P1, TIC, IR1, and other mainstream smart meters. Users can optimize charging and discharging based on real-time electricity prices, household loads, and PV generation, further improving self-consumption and household energy economics.
Driven by smarter energy storage and a shared vision for the future, OneHo will continue to explore home energy innovation, helping households worldwide move toward a green, low-carbon future with smarter, more efficient, and more open home energy solutions.
