Equipment Portfolio:

•Solar Modules: Monocrystalline PERC high-efficiency panels with ≥22.5% conversion efficiency.

•Energy Storage Systems: High-voltage cascaded technology, ≥6,000 cycles (80% DOD), system efficiency ≥95%.

•EV Chargers: Support 800V ultra-fast charging platforms, compatible with Tesla, BYD, and other 主流 models (mainstream vehicles).

Make Homes Energy Centers, Unlock Smart Electricity Lifestyle

•PV Self-Sufficiency: 6-12 solar panels generate 8-15 kWh daily, meeting household electricity and vehicle charging needs at as low as 0.3 USD/kWh (off-peak hours).

•Storage Mutual Support: 5-15kWh home energy storage batteries store solar power during the day and switch to grid power at night, saving 3,000-5,000 USD annually on electricity bills.

•Intelligent Charging: 7kW/11kW AC chargers support APP 预约充电 (scheduled charging), with off-peak charging costs as low as 1/15 of fuel vehicle expenses.

Three Modes for Flexible Switching:

•Economic Mode: Prioritizes PV/storage power, automatically supplementing with low-cost grid power during off-peak hours.

•Low-Carbon Mode: 100% renewable energy use, achieving zero carbon emissions.

•Emergency Mode: Automatically switches to backup power during grid outages, ensuring 72-hour supply for essential appliances like refrigerators and lighting.

Policy Incentives: Eligible for national PV subsidies (0.3 USD/kWh) + local energy storage subsidies (up to 1 USD/Wh), with the shortest 3.8-year payback period.

PV Power Plant Energy Storage Coordination Solution

Solve Curtailment Issues, Enhance Plant Revenue, Support Grid Stability

Core Functions:

•Power Smoothing: Millisecond-level response to PV fluctuations, controlling output volatility within 5% (national standard ≤20%), meeting strict grid connection requirements.

•Peak-Valley Arbitrage: Store power during off-peak hours (23:00-7:00) and discharge during peak hours (17:00-21:00), profiting from 0.6-1.0 USD/kWh tariff differences.

Virtual Power Plant (VPP): Collaborate with PV plants to participate in grid ancillary services, generating 30,000-50,000 USD annual revenue per MW of energy storage
