1. External Battery Design:Uses external batteries for higher inverter efficiency and reduced overload risk.
2. Wide Voltage Input:Supports DC 10 - 32V (12V) or DC 20 - 64V (24V) input, compatible with various batteries.
3. Multi - Output Ports:Features AC (220V/50Hz pure sine wave) and DC outputs to power diverse devices.
4. Smart Power Switching:Automatically switches between utility power (with charging) and battery power during outages.
5. Comprehensive Protections:Includes over - voltage, under - voltage, over - load, short - circuit, over - heat, and reverse - polarity protection.
6. High Surge Power:Peak power up to 2x rated power (e.g., 2000W for 1000W model) to handle high - startup - current devices.
