The APsystems ELS series offers a modular, single-phase AC-coupled energy storage solution built on our innovative Module Level Power Electronics (MLPE) technology. Designed for residential solar applications, the ELS system includes a single-phase battery charger and APsystems low-voltage batteries, with compatibility extending to a growing list of LiFePO4 brands*.
Intelligent software and integrated monitoring provide automated energy management across multiple modes—backup, self-consumption, and peak-valley time—helping homeowners secure critical loads during outages and optimize energy savings.
Engineered for efficient energy use, this low-voltage inverter delivers up to 12,000 VA of nominal power and 18,000 VA peak backup capacity. The ELS series also supports seamless integration with PV generation, energy storage, and EV charging, making it a flexible solution for residential, commercial, and industrial energy needs.
