Not For 7.5KW PowerPact
By Karl S
Washington
Purchased 12/30/2021 |
Review Posted 01/31/2024
Even thought the 7.5 KW PowerPact Owners Manual says this will work, it won't and neither will MobilLink.

Stop Working LOST SIGNAL
By Gregory H.
Taylor, Michigan
Purchased 09/14/2021 |
Review Posted 10/28/2021
It worked great for a few weeks. Then it's as if it lost connecting signal. Only thing it does now is all 3 modes flash. That is what it is supposed to do if it has lost the signal / to far away. I put it next to the unit and install batteries. 3 modes continue to flashing. LOST SIGNAL

Limited Usefulness
By Frank P.

Review Posted 02/02/2021
This was a replacement for my original GENERAC original monitor & control device that constantly lost it’s signal and had to be reset. This unit does nothing more than let you know if there is a problem with your generator. You cannot see or set any functions. I purchased the cellular monitor MOBIL LINK device and will install that as soon as weather permits.
