Discover Battery HELIOS Hybrid Inverter Bundle 16kWh + Megarevo 12K Inverter

The Discover HELIOS Hybrid Inverter Bundle HIB-MGR-16000 is a pre-engineered energy storage system that pairs one Discover HELIOS lithium battery (16.08kWh usable energy) with a 12kW Megarevo hybrid inverter. It is built for whole-home backup, solar self-consumption, and hybrid energy management in residential and light commercial applications, with a 200A whole-home passthrough.

The battery, inverter, and system components ship together as a validated set, which reduces on-site wiring and configuration time and makes commissioning more predictable. The system supports grid-tied, hybrid, and off-grid operation, closed-loop battery communication, generator integration, and integrated monitoring. Additional HELIOS capacity can be added later for scalable expansion.
