Overview:
The ELS7.5-15k Series low-voltage single-phase on-grid hybrid inverter is designed for residential, industrial, and commercial
energy storage applications. It integrates energy storage and grid export capabilities for intelligent, efficient energy management.
During the day, PV energy can be routed to power loads, charge batteries, or export to the grid, helping improve returns and
operational flexibility. At night or during peak-rate hours, the battery can discharge to support continuous power supply. The
system also supports charging batteries from the grid, allowing energy to be stored anytime for backup.
Built for diverse and demanding usage scenarios, the ELS series delivers safe, reliable performance while helping maximize self-
consumption and giving users greater control over their energy, balancing cost savings with energy independence.
