EPEVER Kirin Series: Off-Grid Inverter/Charger

Subtitle: Multi-Source Charging, Dual Output & Scalable Power for Unstable Grids

Core Product Advantages

• Multi-Source Charging Flexibility: Powers up via solar PV (80-500Vdc input range, max 32A current), utility, or oil generator, adapting to diverse energy sources.
• Dual Pure Sine Wave Output: Delivers stable 220/230VAC±3% power (THDv ≤3%) to protect sensitive electronics, with independent main/second load cut-off/recovery settings.
• Powerful Scalability: Supports single-phase/three-phase parallel operation of up to 16 units, expanding capacity to meet large energy demands.
• Dual Operation Modes: Works with or without batteries; sleep mode triggers automatically under low power output or low battery voltage to save energy.
• Smart Monitoring & Data Tracking: Isolated RS485 interface connects to Bluetooth/WiFi/4G for remote control; optional high-resolution color LCD; stores 25,000 historical data records for performance analysis.
• Comprehensive Safety: Battery/PV reverse polarity protection, full electronic safeguards, and IP20 enclosure with anti-dust kit ensure stable, safe operation.
• Seamless Switching: Inverter-to-utility (10ms) and utility-to-inverter (20ms, load >100W) switching for uninterrupted power.
