Solar Power — The Battery Bank


The battery bank in your solar technique is by far one of the most critical elements. It is crucial that a quantity of guidelines are followed in order to make certain that your battery bank gives you with sufficient electrical energy and lengthy life at a affordable cost.

Batteries utilized to shop power for your energy program require to be robust each in terms of size and capacity. The higher the capacity, the greater you can anticipate your system to function.

There are frequently two kinds of batteries in use for solar systems — flooded lead acid and gel cells.

Absolutely everyone is familiar with a flooded lead acid battery, it is the type employed in your vehicle. It is dependable, has extended life when cared for, and will make a enormous quantity of power over its’ lifetime. Some upkeep is necessary, typically in the kind of adding distilled water periodically. A flooded lead acid battery will use much more water when it is cycled more rapidly. Low energy draws from your battery will conversely show a lesser consumption of distilled water.

There are many producers who supply incredibly high top quality batteries which are created especially for solar systems. These batteries are typically extremely heavy, which is a result of obtaining much thicker lead plates than a regular type battery. They are produced to deal with the continuous cycling of power in and out. This is in contrast to your car battery, which is developed to provide a large enhance of power when you start your engine. Thereafter, the alternator in your automobile each charges the battery as well as operating the accessories.

Ought to you use a 12 volt method, it will be perfectly safe to charge your battery bank to nearly 15 volts with out harm. A 24 volt technique can go to almost 30 volts. Throughout the summer time months, it is common to see the solar panels produce sufficient power to get a battery bank very close to the 15 or 30 volt range, depending on your battery bank configuration.

A bank of gel cells is not so tolerant of such higher voltages, and you have to guarantee that your controller keeps the voltage at a decrease variety than the lead acid batteries can deal with. It is a very good notion to keep a limit of about 14.2 volts with gel cells. An occasional tiny overcharge may possibly not hurt, but far better to be secure than sorry. Gel cells are more pricey than most lead acid batteries and any severe overcharge will shorten their life span quickly.

When you set up your system, consideration ought to be made on no matter whether you will use 12, 24 or 48 volts for the battery bank. You will not get any extra energy by making use of a single number more than the other, but you might save some money if you opt for the 24 or 48 volt systems compared to 12 volts.

DC energy does not travel nicely over extended distances at low voltages. The higher the voltage, the far better it will travel.

Let us use the example of your automobile battery. Notice how heavy the battery cables are? It is that way so they will handle the big amp draw at low voltage when you try to begin your engine. Luckily, the battery is typically located quite close to your starter motor which guarantees all the battery power arrives safely.

With your solar system, there are two distinct areas of travel. Firstly, the energy requirements to travel from the solar panels to the battery bank. Secondly, it wants to travel from the batteries to the inverter.

The power from the panels, making use of a little 500 watt technique for example, will be far significantly less than the power going to the inverter. It is feasible that a 3000 watt inverter, which can temporarily draw 6 or 7000 watts (this is identified as the surge) when anything initial starts — tablesaw maybe — will want to deal with 15 times the amps that the incoming panels will give.

Any provided wire size can manage only so a lot power. Need to you opt for a higher voltage method, 24 or 48 volts, you will demand a smaller wire size to manage a related quantity of power. Because smaller wire is significantly less pricey than thicker wire, a simple configuration alter from 12 to 24 volts is going to save you some cash!
