EG4 EG4-12000XP 12kW Off-Grid Inverter/Charger

EG4 12000XP — 12kW Split-Phase All-in-One Off-Grid Inverter/Charger

The EG4 12000XP is a high-output, all-in-one off-grid inverter/charger engineered for homeowners and properties that have outgrown entry-level solar solutions. Delivering 12,000W of continuous split-phase AC output and a massive 24,000W of solar input capacity, this unit provides the power and flexibility required for large-scale energy systems. At Emston Tech Inc, we offer the 12000XP as a feature-complete solution for those building resilient off-grid homes or whole-home battery backup systems.

12,000W Continuous Output with 18kW Surge — Power a Full-Size Home
The 12000XP provides 12,000W of continuous AC output at 120/240V split-phase—sufficient to run central HVAC, electric water heaters, well pumps, and EV charging simultaneously. For heavy motor-start loads, the inverter handles peak surges up to 18,000W for 5 seconds, ensuring your most demanding appliances start cleanly without overloading the system.

24,000W of Solar Input — Quad PV String Inputs
Equipped with two independent MPPT charge controllers—each featuring two dedicated PV string inputs for a total of four—the 12000XP accepts up to 24,000W of combined solar power. This quad-input design allows you to:

• Wire multiple roof orientations or arrays directly to the inverter.
• Eliminate the need for separate external combiner boxes.
• Optimize production across a voltage range of 120–385VDC with up to 35A per MPPT channel.

100A Bypass and Programmable Smart Port
The built-in 100A bypass allows up to 24,000W of grid power to pass directly to your loads, removing the need for an external transfer switch. Additionally, the unique programmable Smart Port can be configured for AC Coupling (to integrate existing grid-tie inverters) or as a Smart Load Output to manage non-critical loads based on battery state-of-charge.

Automated Backup and Safety Stack
The 12000XP features a dedicated generator port with a 2-wire auto-start function, signaling your generator to run only when battery reserves are low. Safety is built-in with an integrated stack including:

• Arc Fault Protection (AFCI): Detects dangerous faults in PV wiring.
• Rapid Shutdown (RSD): Compliant with NEC 690.12 via external emergency shutoff.
• Reverse Polarity Protection: Guards against installation wiring errors.

Advanced Communication and Scalability:

• Battery Support: Dual chemistry support for Lithium and Lead-Acid 48V banks with 250A max charge/discharge.
• Closed-Loop BMS: Direct communication with EG4 and major third-party batteries for precise state-of-charge reporting.
• Certifications: UL 1741 and UL 9540 certified (when paired with EG4 WallMount 280Ah batteries).
• Scalability: Parallel up to 16 units for a massive combined continuous output of 192kW.
• Monitoring: Plug-in Wi-Fi for remote tracking via the EG4 app and a local LCD for field diagnostics.

5-Year Warranty
The EG4 12000XP is backed by a 5-year full parts and product replacement warranty. Emston Tech Inc stands by this platform’s capability to deliver reliable, high-capacity off-grid power.
