off Grid Solar Inverter 3kw 24V DC AC Pure Sine Wave Charger Lithium Power Inverter UPS Function with Charging

Ups power inverter 24v 3000w solar low frequency off grid inverter with Ac chargerThe advantage of Solar Inverter:1. The Efficiency is up to 99%. 2.  64-bits DSP Intelligent control chip. 3. Result fetched from  effective value, not average value. 4.  Photoelectricity isolation circuitry technology. 5. Switching power is supplied by  the independent system. 6. True  over temperature protection. 7.  The full bridge rectifier and  mainboard structure are highly optimized.  Input and output circuits are isolated. 8.  Strong loading capacity with a true onetime  soft start. 9. New and original electronic components. 10. Internal circuit lines and signal lines are based on  plug-pull blocks, not welding.
