10 Signs it’s Time to Replace Your Boat’s Refrigeration
- Category: Refrigeration
1. Box no longer reaches desired temperature set point
A refrigerator box should be kept at 35-40F for safe food storage. If your box used to do this, but doesn’t anymore, then you could have insulation degradation, perhaps your thermostat isn’t telling the compressor to turn on when the box gets warmer, there may be a refrigerant leak, or your system may simply be showing its age.
2. System works sometimes OK, sometimes not
You can bet your bottom paint that everything will be hunky-dory for month after month, and that the gremlins will strike on the first day of your annual cruise with all the family on board. Time to get proactive and get the fridge fairies on your side with a nice new, shiny ,reliable, fridge system.

I think we all get the idea of what a “By-Pass” is, whether it’s a by-pass road to divert traffic around a city, or a heart by-pass operation to channel blood supply around a restricted artery. So what does a By-Pass Diode do in a solar panel? Obviously it must divert something around something, but what, why, and how?
Right away, let’s quell the myth that By-Pass Diodes are there primarily to improve performance under shaded conditions.
Solar Myth Busters - Revisited

We had another highly successful show in Miami this year, with a lot of interest in our solar offerings, but we still find it necessary to spend considerable time with interested parties having to explain the what’s what of solar power for boats. Evidently there is still a lot of misinformation out there on the subject, so this seems like a good time to re-hash one of our most popular blogs from many moons ago. Here follows a list of ten myths and busts in an effort to set the record straight.
Current Affairs - Making the Right Connections
- Category: Battery
Continuing on the theme of the previous blog, regarding wiring individual batteries in parallel to make a higher capacity bank, now we can look at the best way to wire them up.
I included a teaser graphic in that last blog that showed two batteries wired in parallel and with the two main cables, one positive and one negative, both connected to one battery. I expected a flurry of comments on this, but to my surprise received only one. Mr. D said that the configuration shown would result in uneven current draw from each battery, resulting in greatly reduced cycle-life of the first battery in line. Is that so?
And if so, what is the best configuration? What are the alternatives?
Yipee! Time to put on the testing hat once again.
