Newbies

I recently joined a Facebook DIY solar group. Some of the advanced groups can be very helpful with advanced tips. This was not one of them. In fact, this may have been the opposite of that, at least in many cases.  It still keeps me up to date on popular equipment and trends, but, hoo

A Sea Story or Lithium 10–Journey Into Darkness

Every summer I make a point of visiting University of West Florida (UWF) Archaeology Field Schools. One of them is underwater, studying shipwrecks of the 1559 Luna fleet.  This fleet brought settlers to establish Pensacola, America’s first European try for a permanent settlement. I was feeling pretty good about the Lithium Iron Phosphate (LFP) batteries

Stand By

I’m changing out the 5kw inverter in my boat, installing a 3.5kw unit.  Do I need less power?  No, I need an inverter that runs to spec and does not melt the rubber transformer mount when you run it over 10% for a period of time.  Good electronics, but not enough transformer.  Typical Chinese math

After much shifting of plans, The Sun King, newly equipped with a semi-massive Lithium Iron Phosphate (LFP) battery stack, cast off in search of adventure and battery performance info. For review, Sun King was the next progression in my quest for electric boating.  Knightmare, my first effort, was successful, but limited in range.   No solar.

Such a Deal

John Kimball, owner of Sun Electronics, proclaims to offer the best deals on solar panels. Have you considered the best of the best deals? Throughout my long life I have mostly bought used vehicles and for cash.  I probably paid twice for the new Corolla my wife insisted on getting back around 1981.  Interest rate

A Little Late

Hopefully, not too late. Last time I promised a series on emergency backup power, with and without solar. I also promised it would take a while because I’d need to take some pictures and make some drawings. Writing a column isn’t just writing. Writing is easy, like running off at the mouth, but people like
