PV-Storage Hybrid Grid-Tie & Off-Grid Intelligent Power Solution
PV + Energy Storage + Smart Switch | Seamless Grid/Off-Grid · High Flexibility · High Reliability
IMAX Power PV-Storage Hybrid Grid-Tie & Off-Grid (Hybrid/Switchable System) Integrated Solution features ultra flexibility and seamless switching. The system integrates dual-mode operation of grid-tie and off-grid. It intelligently operates in grid-tie mode when the grid is normal, realizing self-consumption, feed-in to grid, and peak-valley arbitrage. When the grid is down, it switches to off-grid mode in milliseconds seamlessly, ensuring uninterrupted power supply for critical loads. It is the preferred solution for residential, commercial & industrial, and high-reliability power supply scenarios.
| Topology Type | Topology Diagram | Architecture & Core Advantages |
|---|---|---|
|
AC Coupling Topology Industry Mainstream · Compatible Expansion |
|
Architecture: PV inverter and energy storage PCS are connected to AC bus separately, realizing seamless grid/off-grid switching through hybrid inverter or EMS + fast switching device. Advantages: Suitable for retrofitting existing PV systems with energy storage, flexible deployment, strong compatibility, wide scenario coverage, easy construction. |
|
DC Coupling Topology High Efficiency · Smooth Switching |
|
Architecture: PV and energy storage are connected in parallel on DC side first, sharing one PCS for grid feed-in or load power supply, reducing multi-stage conversion loss. Advantages: Conversion efficiency increased by 3%~5%, higher energy utilization, smoother and shock-free mode switching, faster system response. |
Core Advantages
- ✅ Seamless Switching · High Reliability: Millisecond-level grid/off-grid switching, zero power outage, no flicker, no sense transition for critical loads.
- ✅ Self-Consumption · High Profit: PV self-consumption rate increased to over 80%, combined with peak-valley arbitrage, significantly reducing electricity costs.
- ✅ Flexible Operation · Wide Adaptation: Supports grid feed-in, off-grid self-sufficiency, demand response, adapts to various electricity prices and grid policies.
- ✅ Smart O&M · Fully Automatic: EMS intelligent scheduling, no manual intervention, 7×24h stable power supply, supports remote monitoring.
Application Scenarios
