Power Sonic (PULSE-INV-12K-LXP) 12LW 2PH Inverter

The Power Sonic PULSE-INV-12K-LXP is a 12 kW split-phase (two-phase) wall-mounted hybrid inverter. Specifically, it is the inverter half of the Power-Sonic Pulse residential energy storage system. First, it manages charge and discharge for 1 to 15 PULSE-ES-5K battery packs. Then, it delivers whole-home backup with under-10 ms transfer switching during a grid outage.

How the Power Sonic PULSE-INV-12K-LXP is used

Therefore, installers pair this inverter with one or more PULSE-ES-5K LiFePO4 packs to build a residential or small-commercial ESS. Also, the inverter supports grid-tied, off-grid, and hybrid configurations. In addition, it handles peak shaving, load shifting, and sell-back to grid where utility tariffs allow. As a result, homeowners get backup, daily energy management, and solar coupling in one unit.
