This last winter and spring was filled with great projects. I am staying focused on improving charging and storage systems on motor yachts.  In addition to many smaller projects I was able to complete three projects in my main areas of interest that seem to offer cruisers the most benefit.  

I improved the overall performance of a traditional lead acid storage system by eliminating battery isolators, improving the wiring of the alternators to the battery bank, and charging all the other batteries on the boat with Victron DC to DC chargers. 

Also, working with the customer to build a system that he envisioned, I completed the installation of a lithium battery bank.  In this case the BMS’s were internal, and we managed to make very few changes to the boats existing electrical system, including keeping the Magnum inverter and the Balmar regulated alternators.

And finally this spring I installed a 600 Watt solar charging system on a motor yacht.  Mounting the panels is always challenging and I was pleased that I got it done within budget.  The customers spend most of the summer away from docks, so eliminating generator run time was the goal.  I am happy to report that the panels are performing well beyond what we expected and the customer is thrilled!  I keep up with the latest in solar technology with great support from NAZ Solar Electric formerly Northern Arizona Wind & Sun.

This coming winter I am looking forward to offering Victron’s GlobalLink 520.  I think this is a great product!  With no monthly monitoring fee the GlobalLink can keep you informed all winter, giving you peace of mind, knowing that your boat is safe.  It can monitor a ton of data from your boat and make it available to you anywhere in the world.  I know for me personally having just three basic pieces of information at my fingertips would help me sleep better at night: battery voltage, shore power status, and the temperature/ humidity onboard.  And another one I am going to look into adding is the monitoring of bilge pump cycles.

SOLAR CHARGING spring 2022

(4) 400 Watt solar panels

This week I finished a 1,600 watt solar project.  This rounds out the charging sources for a new 1,120 amp hour lithium battery bank.  The charging sources are two Victron 24/3000/70 MultiPlus inverter chargers (shore and generator power), a Wakespeed controlled 140 amp 24 volt alternator (main engine), 200 amp 24 volt Panda generator, and two Victron MPPT 150/35 SmartSolar charge controllers using four 400 watt solar panels.
