Clean Power for Every Home
Power your home with clean, reliable solar energy and intelligent battery storage. Yiwei's residential solar + storage solutions help homeowners generate, store, and manage their own electricity — reducing bills and ensuring power when the grid goes down.
Our system combines high-efficiency photovoltaic modules with safe, long-lasting lithium iron phosphate batteries and a smart hybrid inverter. It automatically stores excess solar generation during the day and discharges it in the evening, maximizing self-consumption and reducing reliance on the grid.
From rooftop PV to wall-mounted LFP batteries and smart hybrid inverters, every component is engineered for seamless integration and long-term performance in homes across Europe, Southeast Asia, and Central Asia. Monitor production, consumption, and savings from anywhere with our intuitive mobile app.
Why Choose Solar + Storage
A complete residential energy system that delivers savings, resilience, and peace of mind.
Maximize Self-Consumption
Store excess solar energy generated during the day and use it at night, raising self-consumption rates from 30% to over 80% and dramatically lowering your electricity bills.
Reliable Backup Power
When the grid fails, your battery system automatically switches to backup mode, keeping essential appliances running — from refrigerators and lighting to internet and medical devices.
Time-of-Use Optimization
Smart algorithms charge the battery during off-peak low-tariff hours and discharge during peak high-tariff periods, unlocking additional savings beyond solar self-consumption.
Smart Energy Management
Monitor real-time production, consumption, and battery status through a user-friendly app. Set preferences, receive alerts, and optimize your energy use from anywhere.
Engineered for Simple Integration
Every residential system is built around four core components that work together out of the box. Modular design means you can start small and expand storage capacity as your needs grow.
- High-efficiency monocrystalline PV modules (400–600 W)
- Wall-mounted or stackable LFP battery, 5–25 kWh usable capacity
- Hybrid inverter with UPS-level backup switching
- Wi-Fi / 4G smart monitoring with mobile app and cloud dashboard
Built for Every Living Space
From compact urban homes to large rural residences, our systems adapt to your roof, your lifestyle, and your local grid conditions.
Urban & Suburban Homes
Rooftop solar arrays paired with wall-mounted batteries fit seamlessly into garages or utility rooms, providing clean power and backup for typical household loads.
Rural & Off-Grid Residences
Larger PV and battery configurations with optional generator input deliver reliable electricity in areas with weak or unstable grid infrastructure.
Apartments & Balcony PV
Plug-and-play balcony solar modules paired with small-capacity storage allow renters and apartment dwellers to benefit from self-generated clean energy.
