Father's Day Promotion

Your boat's electrical system can be overwhelming. If you are not sure where to start, or if you would like to learn more about your electrical systems, book an Electrical Audit with PYS

Where is the best place to install a solar panel on my boat?

We get this question a lot and it all depends on what type of boat you have and how much solar “real estate” you have available. The first consideration is shadows. If you own a sailboat, your biggest concern will be the shadows cast by the mast, boom and rigging. On a powerboat, you will have to consider the arch and antennas......

Do Lithium Iron Phosphate (LiFePO 4) Batteries Share Your Values?

Lithium Ion (LiFePO 4) battery technology is widely available and becoming a viable option for pleasure vessel owners. Do you value any of the following features offered by lithium battery technology?

We Are Celebrating Our 10 Year Anniversary - A Message from Jeff Cote

It’s hard to believe it has been a decade since we opened our doors. PYS has come a long way from one employee, one truck and a shared office over Skyline Marina. I started this company because, at the heart of it all, I am a boater.

Forcing A Shore Power Plug to Fit

Putting around peg into a square hole. Why it is a bad idea.

Battery Chargers

Any boat that is moored where there is shore power available will benefit by having a battery charger that converts AC power to DC power which can be stored in the batteries.

Pros and Cons of a Traditional Isolation Transformer

A marine isolation transformer is a versatile device that can be used to provide galvanic isolation from shore power systems, to enhance electrical safety and eliminate corrosion caused by stray currents. Some isolation transformers can also be used for raising the shore voltage to deal with voltage drop. Another common use is to adapt the vessel’s internal power system voltage to a higher or lower shore power supply. If isolation transformers are so useful why is every boat not equipped with one?

Charge Distribution

Quite often on boats there will be more than one battery bank that will be charged from a single source, as is very common with an alternator. There are several ways of distributing the power from the charging source to the various batteries allowing prioritization of current flow.

Battery Charging Rates

Slow and steady wins the race when it comes to battery charging. It is important to bring a flooded lead/acid battery to at least 14.4VDC to get the electrolyte circulating and avoid stratification. However, prolonged charging above 14.4VDC can lead to hydrolysis (cleaving of the water in the electrolyte into hydrogen and oxygen).

Negative Battery Switching Troubles

We recently had to trouble shoot a problem on a boat that had negative battery switching instead of positive. In North America, everything is switched (and fused) on the positive side of the battery. In Europe, some boats have both positive and negative battery switching (i.e. Beneteau) however, we have never seen a negative only battery switching before.
