We received an inquiry recently from a customer who is contemplating installing a large 12v (volt) AGM (Absorbed Glass Mat) battery bank, and he asked a pertinent question: Which would be better; several 12v batteries wired in parallel to multiply capacity, or large capacity 2v, 4v, or 6v cell groups wired in series to produce a high capacity 12v bank? Good question.

This customer estimates he needs around an 800 A/hr (Amp/hours at the 20 hour rate) 12v battery bank to achieve the holy grail of running his air conditioning overnight from batteries through an inverter in addition to supplying the regular daily house loads. This is a popular dream of boat owners these days, and highly achievable with the equipment we have available, and there are several battery configurations to consider. Typically it will all come down to what will fit where, so first let’s look at space constraints and then focus on the technicalities. Cost will not be considered in this article as you can’t put a price on creature comforts, now can you?

We’re living in a DIY world with the internet and answers close at hand. When your boat’s refrigeration isn’t working correctly, how many of you go to the internet, forums, manufacturer’s web site to find solutions? We’ve all learned, too often the hard way, that not all web pages are trustworthy sources of information; some information should be taken with a grain of salt; others with a truck load.

Our business is to sell, among other things, Frigoboat and Vitrifrigo refrigeration to boat owners, boat builders, dealers, service companies, RV owners, etc. Since our beginnings in 1992, we’ve wanted to ensure you, the owner/purchaser, know how to get the most out of your new equipment, not only after the initial set up, but over years and years of use. Quality equipment with clear instructions and support, sold to happy customers makes for good trust building, both in product performance and product support.

To that end, we are always fine-tuning our web page with answers to questions asked by our customers. The leading one, and theme to this blog, is troubleshooting a 12v/24v refrigeration system. We recently updated our “Frigoboat Compressor Trouble Shooting Guide” with video links and downloadable print-outs. It starts with the basic questions:

Did you know that if you store wine at higher temperatures than 65°F, you will actually be accelerating the aging process? Conversely, storing wines at colder than 45°F means they will not fully develop, robbing the wine (and yourself) of its full potential. Even that inexpensive bottle of Chardonnay you bought on sale last week can be adversely affected by storing it under your boat's salon settee until you've made room in the ice box, which in itself is normally at 40°F, so not a good place to put your wine anyway.

The temperature at which you store, and serve, your wine will have an impact on its flavor and your enjoyment. Especially if you plan to store your wine for at least 6 months, you know, for that cruise you've been planning to take before life gets in the way. On my boat, wine doesn't last long in storage, but that doesn't mean I want the taste to be compromised because I didn't handle it correctly. Something that could be so easily fixed.
