Three Phase & Multiple MPPT
ET K3040TL-3P3M, ET K5060TL-3P4M
Commercial & Industrial Sites
Overview
Commercial solar inverters are designed to manage the higher power production and consumption required for large projects. If the system includes battery storage, the inverter can store excess solar energy in the batteries or charge them from the grid. Commercial properties usually use three-phase power, and commercial three-phase inverters are built to synchronize with these systems, providing a stable current. Choosing the right inverter for a commercial solar or battery system depends on factors such as the size and layout of the solar array, whether a battery storage system is included, the type of electrical system in the building, and local codes and utility policies.
A commercial solar inverter is specifically built to meet the electricity demands of commercial and industrial applications. It is an essential part of a commercial solar power system, converting the direct current (DC) produced by solar panels into alternating current (AC) for use in commercial buildings, factories, and other large facilities.
The ET K3040TL is a three-phase inverter designed for small commercial installations. This commercial solar inverter provides high reliability, low lifetime costs, and leading efficiency in an easy-to-install system. It offers the same reliability, efficiency, simple installation, and serviceability as larger commercial inverters. It is suitable for smaller PV system designs or as a component to complete larger PV systems.
