Reverse Polarity Alarm
An essential aid for traveling boaters when connecting to unfamiliar dockside power. The quality of marina wiring can vary greatly from place to place and from plug to plug. That is why most boats designed to plug into shore power have a polarity indicator. It is usually a warning light on the AC electrical panel, although it can also be an audible alarm. It is an important safety feature that few boat owners fully understand or appreciate.
With a couple of exceptions, it should be standard equipment on every boat that is capable of plugging into a common 120-volt AC shore power outlet. Its purpose is to allow the boat owner to verify that the electrical outlet on the dock is wired correctly.
When the polarity is incorrect or reversed, it is because the hot and neutral wires are switched. Without an indicator light, you will not know when this condition exists.

What a great little piece of tech - I don't know how we got by without it in the past. No more guessing how full the holding tank is or having to clean icky tank senders. This little bluetooth RADAR sending unit mounts on top of the tank and connects wirelessly to our Victron Cerbo.
Setup is super easy, push the button on the unit so it can calibrate to the tank then enable bluetooth and set up your rank dimensions on your Cerbo. It's as easy as that.
We've had it installed and running for about two weeks now and couldn't be more pleased (We like it enough that I ordered a second one for our water tank.)
Lots of wiring - no leaks! Be sure to run ALL the wires through BEFORE completing the run!

"Currently" super happy.
Installed on Yanmar 4JH57 engines with Zeus Controllers - HOLY WOW power. Losing some power at top end but overall very satisfied. Will do a long term review later. Talk about power - hope to never need my generator again!
