Off-Grid Hybrid Inverter with Photovoltaic Storage & Low-Frequency Energy-Saving Transformer
Product introduction:
Off grid inverter is a device that converts direct current (DC) electricity from batteries or solar panels into alternating current (AC) electricity to power appliances in an off-grid system. it is suitable for low power applications. This type of off grid solar inverter include features like battery low voltage protection, battery over voltage protection and overload power protection. the split phase off grid solar inverter is a versatile component in solar power systems that provides essential AC power for off-grid living while supporting various household appliances through its dual voltage outputs.
Product Features:
1. Low-Frequency Energy-Saving Transformer
Full-bridge pure sine wave inverter with low-loss, high-efficiency operation (up to 93% efficiency).
2. Triple-Mode Flexibility
Seamlessly switch between Grid Priority / ECO Mode / PV Priority for optimized energy utilization and flexible deployment across scenarios.
3. Dual Operational Modes
Static bypass (direct grid-to-load) or inverter output with integrated UPS functionality for uninterrupted power.
4. Solar Integration
Built-in 60A high-efficiency MPPT solar charge controller (max PV input: 450V DC).
5. Intelligent Monitoring
LCD+LED dual-display interface to monitor system status, voltage, frequency, and fault codes in real time.
User-adjustable output voltage (90-280V AC) and frequency (50/60Hz ± 0.5%).
6. Advanced Connectivity
Multiple communication interfaces: RS232, Wi-Fi, GPRS, and cloud connectivity via mobile APP for remote monitoring/control.
