Product Introduction
Off-grid solar inverter
1. Basic functions
An off-grid solar inverter is a core device that converts direct current (DC) generated by solar panels into alternating current (AC) and also has battery charging and discharging management functions. Its core features include:
- Independent power supply: Disconnected from the public grid, suitable for remote areas without grid coverage (such as deserts, plateaus, forests, etc.).
- Energy Storage Integration: Stores electrical energy via batteries to ensure continuous power supply during cloudy days or at night.
- Multi-Energy Compatibility: Some models support integration with generators or grid power to enhance system reliability.
2. Working Principle
- DC Input: DC electricity generated by solar panels is optimized by an MPPT controller and stored in batteries.
- Inverter Conversion: DC electricity from the battery is boosted and modulated by an inverter into 220V/50Hz sine wave AC electricity.
- Smart Control: Built-in protection mechanisms (such as overcharge/overdischarge protection, temperature monitoring) extend equipment lifespan.
3. Key Components
- Inverter/Charger: Core power conversion module supporting bidirectional charging and discharging.
- Solar Controller: Uses MPPT or PWM technology to maximize photovoltaic panel power generation efficiency.
- Battery Bank: Typically lead-acid or lithium batteries, with capacity determining system runtime.
- Monitoring System: Some high-end models feature Wi-Fi remote monitoring functionality.
4. Application Scenarios
- Remote Areas: Residential homes, outposts, communication towers, etc., without grid coverage.
- Emergency Power Supply: Disaster relief, outdoor activities (e.g., camping, night market stalls).
- Special Environments: Offshore platforms, mobile vehicles, etc., requiring independent power sources.
5. Selection Criteria
- Power Matching: Select the inverter's rated power based on the total load power (e.g., 3kW for residential or 6kW for commercial use).
- Battery Compatibility: Confirm the supported battery types (e.g., 48V lithium-ion batteries or 12V lead-acid batteries).
- Protection Rating: For outdoor use, choose models with high protection ratings such as IP65.
