BG 20-40KW On-grid Inverter

iMars BG 20-50KW string three phase on grid inverter has been developed by INVT, specially for commercial users and distribute grounded power station. This series adopts the latest technologies and combination of T-type three level topology and SVPWM. It has many outstanding advantages such as power density, modular design, easy installation and maintenance, and highly cost effective. It also provides more flexible system configuration and solutions for distributed PV power station and large PV grounded power plants.

Efficient

▪ Integrated intelligent DC combiner and surge protection improve system flexibility and lower the system cost.

▪ Max efficiency is up to 98.6%, wide input voltage range, adapt to all kinds of solar panels and string configuration.

▪ Dual MPPTs work independently and allow unbalanced input power. One MPPT maximum input is up to 60% of Max. DC power.

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

▪ Reactive power control and Power factor adjustable:0.8 leading~0.8 lagging.

Reliable

▪ IP65 protection level, suitable for various installation environments.

▪ Bus capacitors consist of advanced film capacitors, designed with the latest thermal simulation technology for longer lifespan.

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

Smart

▪ AC output power is adjustable between 1-100%.

▪ 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.

Simple

▪ High power density, small size.

▪ Modular design, easy to maintain.
