Choosing the Right Multi-Battery Isolator

Multi-battery isolators have the ability to charge more than one battery simultaneously from a single power source, not requiring a parallel connection of the battery terminals. The main reason that this is beneficial is due to the fact that a weaker battery connected to a stronger battery will end up draining the charge from the stronger battery. One battery is dedicated to holding the charge for starting up the vehicle, the other battery used for a range of things, including car radio equipment or powering portable devices. Their purpose is to ensure that the starting battery has enough power so that the engine can start and batteries can recharge in case the auxiliary battery fails or drains too much energy.

These isolators are normally used in larger vehicles rather than regular automobiles, like recreational and utility vehicles, boats and planes; they are used in vehicles with large, high-power car stereos and off road vehicles to accommodate high current loads.

In order to determine the correct multi-battery isolator for one’s vehicle, there are a few factors. Size is an important factor. The isolator should have an amperage rating equal to or greater than the peak current output in order to interact properly with the vehicle’s alternator system. Utilizing the recommended wire sizes for specific connection distances is also a factor to optimize the use of the right isolator. Choosing the correct isolator also depends on the number of alternators one has or the amount of desired batteries the system will charge.

You Have the Alternative Power!

With over 280 days of sun in Tucson every year, it’s no wonder more and more Tucsonans are turning to alternative methods of power, like solar energy. As we all know, solar power is the conversion of sunlight into electricity. This can be done directly, using photovoltaic arrays, or indirectly using concentrated solar power. Typically most homeowners will have access to photovoltaic arrays, or solar panels, which convert light directly into an electric current.

The demand for solar power has risen recently, with an expected 75% growth by then end of 2012.  And because of this increasing focus on finding and using renewable energy sources, it has provided ample opportunity for homeowners to employ a deep cycle battery. A deep cycle battery is designed to discharge a steady amount of current over a long period of time. This comes in handy when using devices that require a long surge.

So how does it work? It’s actually pretty simple. Solar panels are used to capture the sun’s energy and then convert it into electricity. Connecting the panels to a deep cycle battery is an ideal way to store that energy for future electrical use. But like all batteries, the deep cycle battery releases energy in direct current, or DC, form. What does this mean for you? Many of our every day appliances, like laptops, power tools and TVs use AC, or alternating current. So how do we convert DC into AC? With the help of an inverter of course.

These small, inexpensive devices can convert the direct current from the deep cycle battery into an alternating current that can be used by normal household devices. And our DC to AC converters can convert 12volt DC into 120volts of AC. It’s perfect for use in Cars, Planes, Boats, RV’s, etc.

With the average household paying nearly $170 each month in energy costs, having an alternative power source is becoming more alluring and not to mention practical. Deep cycle batteries can definitely be a cost effective alternative to rising energy bills. No matter what the application – No matter what the power demand, we have the correct battery for your needs. Call our experts today for advice on how to get started!
