1. Performance Description
² Reliability:Intelligentized, modularized, simple structure design with powerful function and stable performance; the high-quality components and the strict production process make the inverter suitable for severe environment. It also has reliable performance and long lifespan.
² Pure Sine Wave Output: Compared with square wave and modified sine wave, the inverter has stronger load capacity. The apparatus can drive inductive load and any other AC load within the required power.
² LCD Display: The LCD display battery voltage, AC output voltage and status parameters. (Remark: If inverter output capacity ≤2kVA, AC output voltage will not display )
² High Efficiency Transformer Isolation: Power frequency toroidal transformer, which ensures high efficiency and low no-load loss of the inverter.
² Perfect Protection Function: Battery over voltage, over discharge, anti-reverse protection; output over load, short circuit, over temperature protection; lightning protection etc.
² Optional by-pass function: When the battery is over discharge, the inverter will intelligently switch to Utility grid to drive load.
² Optional light control and time control function: According to illumination intensity, the inverter can control output without manual operation. This function is available with our matched controller.
