The EG4 18kPV provides up to 12,000W of continuous split-phase output and utilizes up to 18,000W of solar power through three high-voltage MPPTs. Its 100–600VDC solar input range supports efficient array design, reduced cable requirements, and streamlined installation. The inverter can operate on-grid, off-grid, or in grid-assist mode and supports exporting excess solar energy where permitted by the local utility.

Paired with the 314Ah battery—featuring 16.0kWh of storage, 200A continuous output, 10,000 cycles at 80% depth of discharge, and an advanced third-generation BMS—the system provides stable, long-lasting performance for homes and small businesses.

Closed-loop battery communication allows the inverter and battery to coordinate charging, discharging, monitoring, and system protection. Built-in Wi-Fi provides remote access through the EG4 monitoring platform, while the inverter’s configurable LCD interface allows convenient on-site control.

Designed for safe indoor energy storage, the battery includes automatic self-heating for cold environments, Auto-ID technology for simplified expansion, natural-convection cooling, and flexible wall- or floor-mount installation. The inverter features a NEMA 4X outdoor-rated enclosure, integrated PV disconnect, arc-fault protection, ground-fault protection, and rapid-shutdown support.
