BWT1500 serial 220Vdc &220Vdc modular parallel connection inverter is an inversion device that converts 220V dc/220Vdc power supplied by communication DC power supply into 220V/50Hz sinusoidal AC power. Through conversion on the input DC power, the Pure Sine wave inverter offers users stable and Non-distorted AC power. In case of a power failure in business places, it offers key devices the power of flexible output voltage and frequency.

Basic System Architecture

The following illustration shows the basic application for this inverter. It also includes the following devices to
have a complete running system:

Product Overview

√ ? Digital control: It adopts 32-bit DSP full digital and high-frequency SPWM technology, featuring strong anti-interference ability, fast calculation speed, high intelligence, accurate control precision and pure output waveform
√ ? N+1 parallel redundant design: It can form an N+1 parallel redundant power supply system. The modules are backup each other, with high reliability and flexible configuration.Large 128*64 digital LCD display data information,4 led display working;
√ ? No master-slave parallel technology: The operation and parallel connection of each module are independently controlled by the built-in DSP, no single point of failure, independent flow between modules.
√ ? With hot plugging: no need to do any parameter setting and operation, plug and play, the module automatically enters the normal working state, maintenance and replacement is simple and fast.
√ ? Module built-in bypass: Users can choose inverter priority or bypass priority
√ ? Monitoring management: indicator panel, fault sound and light alarm, RS485 communication interface and fault dry contact.
√ ? Protection function: It has the functions of input over-voltage, output over-voltage, over-temperature, short-circuit and so on.
√ ? High power density: 1/2 19〞 width design, the volume is only half the width of the conventional inverter, saving space and convenient parallel.
