![]() If you're planning to run heat-generating appliances, electric stove, pumps, microwave, iron, hairdryer, etc. The easy way to look at this is that if you only require power for things such as general lighting, small electrical appliances, and any appliances that don't generate heat, 12-volt is usually sufficient for off grid electricity storage. Usually, that will be 12, 24, or 48 volts with higher voltage, generally meaning that less amperage input is required. This is generally defined by the input voltage of the inverter, which changes the DC current into AC current. When setting up your battery bank there are several things to think about. They are the most expensive to purchase. However, they have more cycles and more amp capacity delivered over the life of the battery. Lithium batteries are also on the market now, which some are considering for off-grid applications. These are generally more expensive to buy initially than flooded lead-acid batteries, but what you save in both maintenance time and cost is a consideration for some people. ![]() ![]() ![]() The other two options are absorbent glass mat (AGM) and gel batteries. In the lead-acid category, there are generally three types of batteries: flooded, absorbent glass mat (AGM), and gel batteries.įlooded batteries are maintainable and have to be checked fairly regularly to ensure the water levels are correct and the plates remain submerged. It’s important to take your budget and off grid costs into account as well as the time you want to spend maintaining your off-grid battery bank. There are different types of batteries to consider. Since batteries aren't cheap, the ideal situation is to find a balance between your average usage and what type of energy source you have.įor example, if you have access to hydro through a local utility company, their energy is usually less expensive than any power you can generate. So if your sole interest is from a financial perspective, it is prudent to consider keeping that power source. To begin with, there are different types of batteries, voltages, amperage, and costs to consider when planning your system.

The dilemma you face is that very few areas have a consistent balance of sunshine/nightfall/clear skies/cloudy skies/comfortable temperature day after day, month after month, and year after year. And this is an important consideration when it comes to batteries for living off the grid.ĭo you want to run appliances such as a washing machine or dishwasher in your off grid home in the middle of winter? If so, you'll depend on those batteries. This allows you to run longer without the need to replenish your power. The larger the battery bank, the more power you can store. Yet you don't want to run a generator 24/7. The real advantage with a battery bank occurs when you’re off the grid and want to have power available on cloudy days, nighttime, etc. Batteries for Living Off The Grid: Why a Battery Bank is Best The answer, of course, is not so simple and we will rely on a tried and true lawyer's response: it depends. The next question to consider is: “Do I really need a battery bank?” You literally save “energy” for a rainy day. It is energy generated through the use of a water turbine, a topic for a different article.Ī battery bank is an appropriate term since it's like banking. Our battery bank plays an important role as part of our off grid home system.įor clarity, aqua power is not “Aquaman”. In simple terms, a battery bank is just a place to store energy that you've acquired through the use of generators, solar power, wind power, or even aqua power.
