A barnacle can be good if it’s a BRNKL
For a couple of years I have been looking for an easy way to make sure the shore power was connected and charging the batteries on Roxia. If you are a boat owner you know what I mean. Even if your boat is nearby and it gets stormy the shore power connection can be lost. If charging stops you could run your house bank of batteries below 50%. This is the critical number on a lead-acid battery like flooded cell or AGM. A battery or bank of batteries can operate through thousands of cycles if treated properly but may last less than a dozen if allowed to discharge below 50%.
Our house bank consists of twelve 8D Lifeline AGM batteries wired series/parallel giving us 1,530Ah at 24 volts. We have stacked inverters so we can get 240 volt AC to run anything but not everything on the boat. With two small SubZero refrigerators and one SubZero freezer running all the time I worry that if the power goes off when I’m not on the boat we could discharge the batteries in a matter of days.
After the great NAPS2021 Rendezvous in Poulsbo, WA I became acquainted with the people at BRNKL (pronounced barnacle) Systems. Sean Battistoni walked me through the system in a Zoom call and I realized how easy it is to install. Two keys to the system for me are: 1) All connections happen behind my main electrical panel. There is no need to run wires all over the boat. 2) The monitoring happens through a cell card that works anywhere there is cell service on the globe. Here are some photos of the install and a few screen shots from my cell phone.
I sensed the shorepower after the final breaker in my panel so I can tell if the breaker has tripped. This gives me the added ability to see if I have loaded my generator or shorepower too much with cooking and air conditioning. I can also tell if I forgot to select shorepower or generator…which I have also done.
All in all I am very happy with the installation and the ability to monitor at anytime that I am on the boat or off. The system comes with a camera which I have not yet installed. I am not sure where I want it to point. Some people point it at the main entrance or there shorepower panel. Alerts can trigger a picture taking as well. I can add more in the future.
