ENERGY HUB PREVIEW

Smart Energy. 100% Local. Coming Soon.

Most smart home systems force you into a frustrating compromise: sacrificing your privacy for convenience. They beam your highly personal energy data to distant servers, leaving your home vulnerable to internet outages, server crashes, and annoying "cloud lag." We believe your home should run on your terms.

That is why we are currently developing a revolutionary Energy Hub that processes everything locally, keeping your data exactly where it belongs—with you.

Here is what you can expect:

Absolute Privacy: Your data will never leave your house. We are building a system with zero cloud storage.
Lightning Fast: Powered by lightweight, locally hosted web technology for instant control, with zero "cloud lag."
100% Offline Reliable: Internet down? Your system will keep running flawlessly on your home Wi-Fi.
Secure Global Access: Control your home from anywhere via an encrypted bridge that simply connects you, but never sees your data.
Hacker-Proof: Setup will require physical presence in your home, making remote hijacking practically impossible.

By combining cutting-edge local processing with a secure, invisible tunnel for remote access, we are building the ultimate smart energy experience. You will get all the seamless convenience of modern automation, without ever surrendering control of your digital life.

The future of private, local energy management is currently in development. Stay tuned.

INVERTER TECHNOLOGY

Key Product Advantages

Our inverters highlight several technical and design innovations that set them apart:

Advanced SiC Technology 0.5-1% higher efficiency, higher power density, better heat dissipation, and operations up to 3000m+ without derating.

Max. 15 Units (High Scalability) Parallel connection of up to 15 units for maximum system scalability as power demands increase.

98.4% Max. Efficiency Highly efficient power conversion achieving an industry-leading peak efficiency of 98.4%.

Smart Load Control Intelligent load management with integrated and highly secure leakage current protection.

150% PV Configuration Supports photovoltaic input power up to 150% of the rated AC output power.

110% Output Overload Stable power supply guaranteed with a 110% continuous AC output overload capacity.

180-960V Wider MPPT Range Extended MPPT voltage range for higher energy yields across varying light and module conditions.

APP+H5 Smart Data Analysis Supports batch inverter management, OTA upgrades, 15 languages, and smart data visibility.

Two Independent Battery Ports Mix old and new batteries with different voltages, currents, or BMS protocols. Saves costs on extra inverters.

Software-Based Power Expansion Expand power capacity via software upgrades instead of new hardware, saving 80% or more on expansion costs.

100% Three-Phase Unbalance In off-grid mode, supply 100% of rated power to a single-phase load or output 100% across each phase individually.

Display-Free Design Removal of failure-prone LCD screens lowers repair costs and extends inverter life. Reliance on app and cloud platform.

LOW VOLTAGE (LV)

LV Inverter Lineup

We cover a wide power range from 1.5kW up to 50kW. The Low Voltage (LV) lineup is designed primarily for smaller-scale residential or off-grid applications.

Single-Phase LV Hybrid (3-12kW) Up to 98% efficiency, 150-200% PV input, ultra-quiet (<25dB). 0ms on-grid / 4ms off-grid switchover. Parallel up to 6 units.

Single/Three-Phase LV Hybrid (5-12kW) 165mm ultra-thin IP65 design, massive 166%-400% overload capabilities, dedicated generator ports for smart monitoring.

LV Off-Grid Inverters (1.5-12kW) Built for off-grid. 97.5% efficiency (3-5% higher than market avg) and wide AC input power ranges (190-460%).

HIGH VOLTAGE (HV)

HV Inverter Lineup

The High Voltage (HV) lineup is engineered for more demanding, higher-capacity applications, leveraging the SiC technology for maximum efficiency.

Single & Three-Phase HV Hybrid (5-12kW) 165mm ultra-thin form factor, higher max efficiency of 98.2% and AC voltage range of 168-276V.

Three-Phase HV Hybrid (5-20kW) Supports 100% three-phase unbalance, <10ms grid switchovers, ruggedized for extreme altitudes up to 5000 meters.
