EG4® 18kPV-12LV All-In-One Hybrid Inverter
SKU: EG4HYB12K00V1
UL 1741 SB | IP65 | NEMA 4X | CEC | CSIP
The EG4 18kPV hybrid inverter/charger is a versatile and powerful solution for solar energy users seeking flexibility and efficiency. This inverter is certified electromagnetic pulse (EMP)-hardened, so it is capable of withstanding disruptions caused by natural and manmade EMPs.
It supports off-grid, grid-assist, and grid-tied modes, allowing users to choose between complete energy independence, backup power from the grid, or selling excess energy back to the grid. With an 18kW PV input and 12kW output, the EG4 18kPV offers robust energy handling and can be expanded by paralleling up to 10 units.
Featuring a 600V DC input, the inverter ensures efficient cable management and optimal energy conversion through its three MPPTs. It provides split-phase 120/240V single-unit output or 120/208V service operation. Additionally, it communicates seamlessly with 48V EG4 batteries or other battery brands. The built-in Wi-Fi enables remote monitoring via the EG4 app. Ideal for energy-conscious homes and businesses, the EG4 18kPV is a smart choice for those looking to maximize solar savings and achieve energy independence.

FAQs
Yes, the 18kPV can be AC coupled with up to 21.6kW of PV through an external inverter. This is especially useful when upgrading an existing system without batteries. Ensure that the feed-in inverter is UL1741SA compliant to respond correctly to grid frequency shifts and the 18kPV.
The term “Zero Export” is used throughout the industry to talk about preventing power from being exported to the grid. The reality is that Zero Export is a bit of a misnomer because no hybrid inverter currently available can achieve true zero export. All of them have a margin of error. Hybrid inverters can get it down to 100W or less. However, if there is a load on the output, this will go away.
Usually the utility’s power meter measures sellback. They may replace it as part of the net metering agreement, often free of charge.
The fan speed is temperature-controlled and varies with load. Under light loads, the inverter is nearly silent. At max cooling, fans can reach up to 68dB at three feet.
No, the 18kPV uses common neutral architecture and does not create an internal neutral–ground bond. Ensure an existing bond at the service entry point.
Use the “Time of Use” settings for peak shaving. Refer to the manual (section 6.1.4 and 7) for details.
Internet access is not required for the 18kPV, but it’s highly recommended for easier monitoring and support. Use the provided Wi-Fi adapter or other accessories for setup.
Yes, configure the system as a “microgrid” with the generator on the grid input, leaving the AUX port available for configuring a smart load.
The 18kPV is a high-frequency inverter.
From the monitoring site, you can adjust charge, discharge, and application settings. Advanced settings are accessible through the inverter menu.
No, but using closed-loop battery communication is recommended for better control and support.
