Product Introduction
Introduction to the Solar Inverter and Battery Integrated System
1. Basic Concepts
- The solar inverter and battery integrated system (also known as the “inverter-controller integrated unit”) is a device that integrates photovoltaic inverters, battery charge/discharge controllers, and energy storage management functions into a single unit. It supports both grid-connected and off-grid modes, enabling intelligent coordination between photovoltaic power generation, energy storage, and electricity consumption.
2. Core Function
- Bidirectional Inverter: Bidirectional conversion between DC power (photovoltaic/battery) and AC power (grid/load), with efficiency exceeding 96%.
- Multi-Energy Management: Supports three input sources (photovoltaic, grid power, and battery), automatically switching power supply based on priority (e.g., photovoltaic priority, battery backup).
- MPPT Optimization: Built-in Maximum Power Point Tracking (MPPT) controller, enhancing photovoltaic panel power generation efficiency by 20%-30%.
- Islanding Protection: Automatically switches to off-grid mode when the grid power fails to ensure power supply safety.
3. Typical Application Scenarios
- Residential Photovoltaic Storage System: Generates power from photovoltaic panels during the day to supply loads and store energy, and uses battery power at night to reduce electricity costs.
- Outdoor Emergency Power Supply: Can be paired with a portable battery pack to provide off-grid power for camping and vehicle-mounted devices.
- Microgrid Projects: In small grids under 250 kW, simplifies system wiring and improves reliability.
4. Technical Advantages
- High-Efficiency Integration: Reduces the need for independent devices such as photovoltaic inverters and energy storage converters, lowering system complexity.
- Intelligent Control: Remotely monitors power generation, energy storage, and electricity consumption data via a cloud platform, supporting customizable charging and discharging strategies.
- Safety and Stability: Multiple protection mechanisms (overvoltage, overcurrent, reverse connection protection) and fanless cooling design.
5. Purchase Recommendations
- Power Matching: Residential use recommends 3-10 kW, commercial and industrial use requires 20 kW or above.
- Battery Compatibility: Must be compatible with mainstream energy storage battery voltage platforms such as lithium iron phosphate (e.g., 48V/52V).
- Certification Standards: Prioritize products certified by CE and UL.
