Pure Sine Wave Home Inverter with BMS

Overview

Description

Unstable power conditions, frequent brownouts, and blackouts are common issues worldwide, making reliable home inverters essential for ensuring continuous and stable power supply for sensitive electronics and household operations.

This high-performance, noiseless, and efficient inverter system generates 50Hz/60Hz with 230V AC from a Li-ion battery backup system. The intelligent battery management system (BMS) controls and manages performance, yielding lower losses and clean load waveforms for extended power backup during outages.

System Benefits​:

  • Capacity (rating) ranges from 800VA to 1800VA, providing compatibility for a wide range of appliances and devices.
  • Both low-frequency and high-frequency inverters can be derived from the same system, offering versatility and flexibility for different power conversion needs.
  • An isolated setup to track AC output and an auxiliary flyback power supply provides reliable monitoring, control, and power management for robust and stable operation.
  • A low-cost MCU optimizes performance and reduces system costs.
