Fully Off-Grid Solar-Storage-Charging Integration
100% Self-Sufficient Green Power · Modular Deployment · Minimal Maintenance
Application Pain Points · Solving the Park Energy Dilemma
Against the backdrop of “dual-carbon” goals and urban renewal, traditional grid connection is difficult and costly — off-grid solar-storage-charging is the optimal solution.
Grid Coverage Blind Spots
Wilderness and wetland parks often have no grid access; grid upgrade investment is high and the construction cycle is long.
Severe Load Fluctuation
Daily lighting/AC use coexists with seasonal EV charging spikes, placing extremely high demands on grid regulation.
Missing Municipal Infrastructure
Drainage networks and power demand are rarely planned together, and traditional approaches are inflexible.
High Electricity Costs
Commercial electricity rates plus long-distance line losses are costly, with significant idle drain overnight.
Insufficient O&M Capability
Park management teams lack dedicated electrical staff and need “dumbed-down,” remote intelligent monitoring.
Strict Landscape Integration
Solar and storage installations must blend with the natural landscape, avoiding an “industrial” look and feel.
Six Core Principles · Defining the New Off-Grid Standard
Fully Off-Grid, Independent Operation
No reliance on the utility grid — solar and storage together guarantee round-the-clock self-sufficient power.
Integrated Solar-Storage-Charging
Deep closed-loop from generation to storage to consumption, with millisecond-level EMS response.
Landscape-Friendly Integration
Bionic solar canopies and solar benches coexist naturally with the park environment.
Modular Rapid Deployment
Prefabricated cabin delivery, with on-site assembly and commissioning completed in 3–5 days.
Minimal Intelligent O&M
5G cloud platform plus AI self-diagnosis of faults, with remote management via mobile app.
Flexible Capacity Expansion
Solar, storage, and charging modules configured on demand, with smooth phased upgrades.
Overall System Architecture · The Smart Energy Brain
“Solar first, storage as backup” — daytime green power is prioritized for direct use and charging; at night or on cloudy/rainy days, storage provides seamless millisecond-level switching, ensuring 3–5 days of backup power in poor weather.
Flexible Configuration · Covering Every Use Case
A three-tier standardized solution, covering everything from simple wilderness rest stations to large park service centers — all components are modular and interlocking.
| Tier | Solar Module Capacity | Storage System Capacity | Charging Pile Configuration | Recommended Use |
|---|---|---|---|---|
| Basic | 6 kWp | 10 kWh | 7kW AC slow charging | Wilderness simple rest stop / no-charging-demand power use |
| Standard | 15 kWp | 25 kWh | 7kW slow charging + 60kW fast charging | Urban park comprehensive station / e-scooter charging |
| Flagship | 25 kWp | 55 kWh | 7kW slow charging + 60kW fast charging | Large park service center / new-energy vehicle charging |
Storage Technology Upgrade
LFP-A grade battery cells, over 6,000 charge cycles; wide temperature range (-30°C to 55°C), IP66-rated, weatherproof.
Wind & Solar Expansion Reserved
Supports EVs feeding power back as mobile storage; optional vertical-axis micro wind turbines for a combined wind-solar-storage microgrid.
Core Functions · Multi-Dimensional Smart Empowerment
Energy Management Module
Intelligent EMS dispatch (economic optimization / priority self-consumption / emergency backup), real-time monitoring of solar output, storage SOC, and load; auto-generates peak-valley arbitrage & carbon data reports.
Smart Rest Station Operations
Shared power banks, drinking water, Wi-Fi 6, and information display; smart access control with foot-traffic counting and SOS one-touch calling; self-service coffee kiosk and commercial-community integration.
Remote Monitoring + O&M
5G IoT cloud platform for centralized management; mobile app for real-time viewing of power generation, storage reserves, and charging pile utilization; AI fault self-diagnosis with recommended solutions — O&M cost reduced by over 80%.
Solution Highlights · Redefining the Park Energy Landmark
Fully Off-Grid Independent Operation
Millisecond-level island-mode switching, self-governing battery voltage, self-generation and self-consumption, with surplus power not fed back to the grid — completely free of grid dependency.
Landscape-Friendly Design
Solar canopies, bionic solar carports, and specially designed solar installations preserve a leisurely, relaxed atmosphere to the greatest extent possible.
Flexible Modular Deployment
Factory-prefabricated cabin delivered as a complete unit, on-site setup completed in 3–5 days; no excavation or pipe-laying needed for older parks, allowing smooth capacity expansion and avoiding large one-time investment.
Comprehensive Safety Assurance
Four-tier battery protection plus storage cabinet fire suppression, temperature/smoke sensing; anti-backflow/leakage/lightning-protection grounding; storage cabinet kept away from active zones — dual insurance for electrical fire safety.
Multi-Dimensional Value · A Positive Zero-Carbon Investment Cycle
Investment Payback Period
Standard-tier solutions offer attractive lifecycle returns: 30–80 kWh generated daily, saving 1.5–4.5 RMB per kWh; annual charging service revenue reaches 50,000–120,000 RMB (flagship tier).
CO₂ Emissions Reduced / Year
Each standard system generates 15,000–30,000 kWh of green power annually, equivalent to planting 1,000–2,000 trees — zero fossil fuel consumption, zero exhaust emissions, supporting the city’s “dual-carbon” goals.
Elevated Social Services
Round-the-clock station operation creates a child-friendly rest space and a convenient EV-charging-plus-travel scene, becoming a replicable zero-carbon showcase with real social value.
Cutting-Edge Technology Integration · Rock-Solid Off-Grid Assurance
Integrated Host
Solar inverter + PCS + DC module + EMS fully integrated, eliminating redundant wiring — an industry-leading level of integration.
Extreme Environment Adaptability
Outdoor-rated protection, IP66, operates stably across -30°C to 55°C — able to withstand harsh weather conditions.
AI Fault Self-Diagnosis
The cloud platform continuously learns from operational data, automatically identifying anomalies and pushing recommended solutions — unattended and worry-free.
Multi-Mode Intelligent Operation
Economic optimization / self-consumption priority / emergency backup mode — EMS dynamically adjusts to the optimal strategy.
