EG4 EG412KPV8LV 8kW Hybrid Inverter/Charger

EG4 12kPV (EG412KPV8LV) — 8kW Split-Phase All-in-One Hybrid Inverter | 12kW Solar Input | NEMA 4X

The EG4 12kPV is a high-efficiency, all-in-one hybrid inverter/charger designed for homeowners and off-grid builders who want maximum solar input capacity in a single compact unit. With 12,000W of PV input across dual MPPT channels, 8,000W of continuous split-phase AC output, and a NEMA 4X outdoor-rated enclosure, the EG412KPV8LV delivers a feature set that punches well above its price class. Whether you are building a new solar-plus-storage system or retrofitting battery backup onto an existing installation, Emston Tech Inc provides the 12kPV to give you all the necessary tools in one pre-wired enclosure.

8,000W Continuous Output with Strong Surge Capacity — Power Your Whole Home
The EG4 12kPV delivers 8,000W of continuous AC output at 120/240V split-phase, covering the full electrical demand of a typical home. When heavy motor-start loads demand a burst of extra power, the inverter handles:

• 16,000W for 50 milliseconds
• 12,000W for 1 second
• 10,000W for up to one minute

This ensures HVAC systems, well pumps, and other inductive loads start reliably without tripping the system or shedding other circuits.

12kW of Solar Input — Dual MPPT at 500VDC
Two independent MPPT charge controllers, each rated at 25A, accept a combined 12,000W of PV input across a voltage range of 120–500VDC. It supports arrays sized up to 15,000W to account for real-world production variability. Dual independent channels allow you to wire separate roof orientations or array sections without cross-shading losses, maximizing harvest from every panel. With 99.9% PV-to-battery efficiency, the 12kPV converts more of what your panels produce into usable power.

Reliable Split-Phase Performance & Seamless Backup
The EG4 12kPV can manage up to 4,000W of load imbalance between the two phases for up to 30 minutes, preventing nuisance shutdowns when 120V loads are not perfectly balanced. In the event of a grid failure, the 12kPV switches to battery and solar backup in just 10ms—fast enough to keep sensitive electronics and network equipment running without interruption.

NEMA 4X Enclosure — Outdoor and Coastal Rated
The NEMA 4X rating provides full protection against windblown dust, rain, hose-directed water, and corrosive coastal salt spray. This makes the 12kPV one of the few residential hybrid inverters genuinely suitable for direct outdoor installation in humid, rainy, or coastal environments without requiring additional weatherproofing hardware.
