The battery bank in your solar system is undoubtedly one of the main elements. It is important that a number of guidelines are followed so as to ensure that your battery bank gives you adequate electricity and longevity at an acceptable cost.
Batteries used to store energy for your power system have to be robust both in terms of size and capacity. The greater the ability, the greater you can expect your system to function.
You can find commonly two forms of batteries in use for solar systems – flooded lead acid and gel cells. battery balancer
Everyone is familiar with a flooded lead acid battery, it’s the kind used in your vehicle. It is reliable, has longevity when looked after, and will produce a huge amount of energy over its’lifetime. Some maintenance is important, usually in the proper execution of adding distilled water periodically. A flooded lead acid battery will use more water when it’s cycled faster. Low power draws from your own battery will conversely show a lesser consumption of distilled water.
There are numerous manufacturers who provide very high quality batteries which were created especially for solar systems. These batteries are often very heavy, which is a results of having much thicker lead plates than a standard type battery. They are created to handle the constant cycling of power in and out. This is in contrast to your car or truck battery, which is designed to provide a huge boost of power when you start your engine. Thereafter, the alternator in your car or truck both charges the battery as well as running the accessories.
Should you work with a 12 volt system, it will soon be perfectly safe to charge your battery bank to nearly 15 volts without damage. A 24 volt system can visit nearly 30 volts. During the summer months, it’s common to begin to see the solar panels produce sufficient energy to acquire a battery bank very near the 15 or 30 volt range, depending in your battery bank configuration.
A bank of gel cells is not too tolerant of such high voltages, and you need to ensure your controller keeps the voltage at a lesser range compared to lead acid batteries can handle. It is advisable to maintain a control around 14.2 volts with gel cells. An unexpected small overcharge might not hurt, but more straightforward to be safe than sorry. Gel cells are more pricey than most lead acid batteries and any serious overcharge will shorten their expected life quickly.
When you create your system, consideration should be produced on whether you will use 12, 24 or 48 volts for the battery bank. You will not get any extra power by utilizing one number over one other, but you might save some funds if you choose the 24 or 48 volt systems compared to 12 volts.
DC power doesn’t travel well over long distances at low voltages. The bigger the voltage, the greater it’ll travel.
Let’s use the exemplory instance of your car battery. Notice how heavy the battery cables are? It is this way so they’ll handle the large amp draw at low voltage when you try to start your engine. Fortunately, the battery is generally located very near to your starter motor which ensures all the electric batteries arrives safely.
Together with your solar system, there are two distinct areas of travel. Firstly, the energy needs to visit from the solar panels to the battery bank. Secondly, it needs to visit from the batteries to the inverter.
The ability from the panels, employing a small 500 watt system for instance, will soon be far less compared to power likely to the inverter. It is possible that the 3000 watt inverter, that may temporarily draw 6 or 7000 watts (this is called the surge) when something first starts – tablesaw maybe – will have to handle 15 times the amps that the incoming panels will provide.
Any given wire size can handle only so much power. Should you go for an increased voltage system, 24 or 48 volts, you will require a smaller wire size to take care of an identical number of power. Since smaller wire is less expensive than thicker wire, a straightforward configuration change from 12 to 24 volts will probably save some money!
