EG4® 18kPV-12LV All-In-One Hybrid Inverter

SKU: EG4INV18KPV00V2

UL 1741 SB | NEMA 4X | CEC | CSIP

The EG4 18kPV hybrid inverter/charger is a robust solution for solar users seeking flexibility and efficiency. EMP-hardened to withstand natural or manmade disruptions, it supports off-grid, grid-assist, and grid-tied modes, allowing for energy independence, backup from the grid, or selling excess energy.  

With 18kW PV input and 12kW output, the inverter offers high energy handling and can parallel up to 10 units for expanded capacity. A 600V DC input and three MPPTs ensure optimal energy conversion and streamlined cable management. The 18kPV provides split-phase 120/240V or 120/208V output and integrates seamlessly with 48V EG4 or other battery brands. Built-in Wi-Fi enables remote monitoring via the EG4 app, making it ideal for homes and businesses focused on solar savings and 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 Exportis 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 neutralground 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.
