BG 4-6KW On-grid Inverter

BG 4-6KW On-grid Inverter

BG series three phase inverter has been developed by INVT, specially for residential and small commercial customers. This series adopts the latest technologies and combination of T-type three level topology and SVPWM. It has many outstanding advantages such as compact size, light weight, easy installation and maintenance, and most of all, competitive prices. It also provides flexible system configuration and monitoring solutions for household and commercial systems.


▪ The core technologies are from Germany.

▪ Wider voltage range, lower starting voltage and higher conversion efficiency (Max efficiency can be reach to 98.3% ).

▪ Two MPPT, adapt to the complex environment of roof, improve power generation.

▪ Adopt the latest technologies and combination of T-type three level topologies and SVPWM.


▪ Aluminum casing, natural cooling, IP65 protection level.

▪ Adopt internationally famous brand components to ensure the stable operation of inverter.

▪ Insurance by well-known international property insurance company (AIG) for Products /Completed Operations Liability Insurance.


▪ Smart grid adaptive to meet the requirements of various power grid accesses.

▪ Variety of monitoring modes: APP (one-button registration), large screen data monitoring center, cloud monitoring platform.

▪ Support RS485,GPRS,WIFI, Ethernet.


▪ Home appliance design, easy to operation.

▪ Small in size, light in weight, easy to install by a single person.
