Eliminate the ethernet run to your inverter

Eliminate the ethernet run to your inverter

Running cat5 cable to a mounted inverter on the side of your house or out at a remote cabin site is a pain point most installers know well. This SolarEdge cellular plug-in connects your SetAPP residential inverter directly to the monitoring platform over cell signal — no router, no trenching, no additional internet infrastructure needed. At Off Grid Vault, every component we carry is vetted for real-world performance, and this modem is the exact unit we would specify for a remote installation where running wire is impractical or impossible.

Five years of cellular data included upfront

Five years of cellular data included upfront

The CELL-B-R05-US-S-S2 ships with a five-year data plan built into the purchase price. No monthly subscription to remember, no separate account to manage, no surprise bills. Comprehensive US coverage means your inverter reports production data and status to the SolarEdge monitoring platform regardless of where your system is located — rural homestead, remote cabin, or a property where the only internet option is satellite at unreasonable cost. This is off-grid proven connectivity for installations that cannot depend on wired broadband.

Remote monitoring and troubleshooting from anywhere

Remote monitoring and troubleshooting from anywhere

When your inverter is connected via cellular, you gain full visibility into system performance through the SolarEdge monitoring platform — production data, fault codes, and status alerts delivered to your phone or browser. For remote properties, this eliminates the need for a site visit just to check whether the system is operating correctly. If something triggers a fault, you see it immediately and can coordinate a targeted response. The 25-year limited warranty from SolarEdge backs this modem for the long haul, matching the lifespan expectations of a serious off-grid installation.

Compatibility Check

Confirm your setup before ordering — this modem is built for a specific inverter family and cellular environment.

  • Works only with SolarEdge SetAPP series residential inverters
  • Requires active cellular signal strength at the inverter installation location
  • 5-year data plan activates upon modem connection to the SolarEdge monitoring platform

Where This Fits

Built for installations where running network cable to the inverter is impractical or unnecessary.

★★★★★
“My inverter is mounted on the far side of my shop, about 150 feet from the house. Running ethernet wasn't happening. Plugged this in, connected to the SolarEdge app within five minutes, and I can see my production from my phone anywhere on the property. Five years of data included with no monthly bill sealed the deal.”

Frequently Asked Questions

If your inverter is mounted near your router, ethernet is an option. But for remote installations — a cabin 200 feet from the house, a homestead where trenching costs more than the modem, or a property with no wired internet — this cellular plug-in eliminates infrastructure costs entirely. Factor in the five-year data plan with no monthly fees, and the math favors cellular for most off-grid and semi-rural sites.
This cellular modem is designed specifically for the SolarEdge SetAPP series of residential inverters. It plugs directly into the inverter's communication port. If you are running a SolarEdge HD Wave or other non-SetAPP model, this unit will not work — check your inverter's product manual for the correct cellular modem SKU. Off Grid Vault can verify compatibility before you order.
The 25-year limited warranty is provided directly by SolarEdge and covers manufacturing defects in the cellular modem hardware. This aligns with SolarEdge's standard warranty approach for their residential product line. For specific coverage terms, exclusions, and claim procedures, the full warranty document is available through SolarEdge. As an authorized dealer, Off Grid Vault facilitates warranty claims on your behalf.
The five-year cellular data plan is tied to the modem unit itself. Based on SolarEdge's standard activation process, the plan typically begins when the modem is first connected and registered on the SolarEdge monitoring platform. If you are not ready to install immediately, the modem can be stored without activating the data plan until your system is commissioned.
This modem connects your inverter to the SolarEdge monitoring platform via cellular signal — it does not require a grid connection to function. However, the CELL-B-R05-US-S-S2 is designed for SolarEdge SetAPP residential inverters, which are primarily grid-tied string inverters. If your off-grid system uses a different inverter architecture, contact Off Grid Vault and we will identify the correct connectivity option for your setup.
SolarEdge provides comprehensive US cellular coverage, but signal strength varies by location. Before installing, check cell reception at your inverter's mounting location using your phone. If you have at least one bar from a major carrier, the modem should connect reliably. For weak-signal locations, an external cellular antenna may improve performance. Off Grid Vault can help you assess feasibility during a free system design consultation.
