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.
