EG4 18kPV Hybrid Inverter — 18,000W PV Input / 12,000W Output, 48V Split Phase

The EG4 18kPV is an all-in-one hybrid inverter built for serious off-grid and grid-tied solar installations. With three independent MPPTs handling up to 18kW of PV input and a 48V battery bank, it delivers full split-phase 120/240V (or 120/208V) household power and can run in off-grid, grid-assist, or grid-tied modes. Up to 10 units can be paralleled for larger installations, and it's EMP-hardened for added resilience.

Key Specs:

• Continuous Output: 12,000W @ 240V (10,400W @ 208V)
• Surge Power: up to 15,500W (5 min, with PV assist)
• PV Input: up to 18,000W across 3 MPPTs, 140-500VDC range
• Battery Voltage: 48V nominal (40-60VDC), max charge current 250A
• AC Output: split-phase 120/240V or 120/208V
• Efficiency: up to 97.5% (PV-to-grid), CEC rated 96.9%
• Certifications: UL 1741 SB, NEMA 4X, CEC, CSIP compliant
• Dimensions: 34.3 x 20.5 x 11.2 in.
