Product Summary:
The EG4 12kPV Hybrid Inverter is a powerful, all-in-one solution designed for both on-grid and off-grid energy systems. This is a hybrid inverter, which means that it inverts the energy from your home’s solar energy system from DC to AC so that it can be used by the home (and the grid).
It also offers numerous other features and functionality to serve as a single point of management for your home’s entire electrical energy infrastructure. Delivering 8,000W of continuous split-phase power with support for up to 12,000W PV input, it provides efficient, reliable performance for residential solar and backup applications.
Featuring dual MPPT inputs, the 12kPV maximizes solar production while seamlessly managing energy from solar, battery, and grid sources. Built-in breakers, fast UPS transfer (~20ms), and advanced system protections ensure uninterrupted operation and safe, dependable performance.
Designed with ETL & cETL certifications and built for durability, transformer-free architecture, the inverter offers lightweight, energy-efficient performance without sacrificing power or reliability. With smart features like load control, AC coupling, and peak shaving, it helps reduce energy costs while providing backup protection during outages.

Frequently Asked Questions
Is the 12kPV UL 9540 certified with the ETHOS?
Yes. The 12kPV is UL 9540 certified with closed-loop communication for both grid-tied and off-grid operation, and BigBattery ETHOS is listed as a compatible battery, alongside EG4 batteries. That combination is what makes it viable for a permitted grid-tied install.
12kPV or 18kPV: which one?
The 12kPV gives 8,000W continuous output with 12,000W PV input. The 18kPV gives 12,000W output with 18,000W PV input. Choose the 12kPV for a typical home with a moderate solar array. Choose the 18kPV for whole-home backup or a large array.
Can the 12kPV do AC coupling with existing solar?
Yes. It supports AC coupling for system upgrades and retrofits, so you can add battery storage to an existing grid-tied solar system without replacing your current inverter. It also supports load control and peak shaving to reduce energy costs.
Does the 12kPV work with the GridBOSS?
Yes. The EG4 GridBOSS 200A MID is offered as a compatible add-on. GridBOSS adds advanced load management, AC coupling and generator support, which matters most on whole-home installations where you are managing which circuits stay live during an outage.
How fast does the 12kPV switch during an outage?
UPS transfer is around 20ms, fast enough that computers, routers and sensitive electronics stay running without rebooting. It also includes built-in breakers and advanced system protections to simplify installation and improve safety.
