Myth Vs. Fact. Batteries should not be stored on a concrete floor.

batteries Myth - This false notion has been around since about WWI and just never seems to die. In the early 1900's battery cases were made of wood products and sealed with asphalt. The battery acid would slowly leak and often formed a discharge circuit through the acid pool around the battery case. Plastic battery cases solved that problem.

A Little Love During the Planning Stage, Will Help Your Solar Batteries Live Longer.

battery Deep cycle batteries need a little love to squeeze every life cycle out of their service life. Sulphation, which is irreversible, is caused if the battery is not sufficiently recharged after each discharge. Over time, Sulphation crystals grow and can no longer be transformed into lead or lead oxide entirely. In the operating period, the active mass decreases, and the dischargeable capacity falls. The lower part of the battery cell is mainly affected by sulphation since a full charge is rarely attained there. You can avoid this by matching your daily solar impute during the shortest days of the year with your energy budget, so your batteries are fully charged each day.

OutBack Sealed AGM Energy Storage System

roof rackOutBack's new EnergyCell RE high-capacity solar battery employs a modular design concept with an integral racking system that can be installed more quickly and efficiently than most Valve Regulated Lead Acid (VRLA) batteries of this size. The included racking system is deployed with four cells per shelf, so a 48 VDC system typically uses six shelves. The 1600RE is three modules per shelf and eight high. Terminals and connecting plates, as well as clear safety covers, are also included.

Deep Cycle Solar Batteries for Solar Systems. Lithium- AGM (Sealed) - Lead Acid

Multiple Parallel Battery Strings. How Many Are OK?

battery Multiple parallel battery strings are only good up to a certain point. 1 string is ideal. 2 strings are okay. 3 strings are tolerable. More than 3 strings is just BEGGING for trouble! Tiny resistance differences between strings are unavoidable, and electrons being the supremely lazy things they are will always try to take the route of least resistance. With 2 or 3 strings battery string imbalances can usually be kept within control. But with more than 3 strings it’s inevitable that some strings will end up doing all the work, and some will do next to nothing. Neither condition is good for solar battery life expectancy.

 

Converting Watt-hours to Amp-hours

  • Solar Batteries are rated in Amp-Hours (Ah)
  • To convert Wh to Ah, divide WH by the battery voltage; 9500Wh/day ÷ 48VDC = 197.9Ah/day
  • Round up to 200Ah - This example system will use about 200Ah from the 48V solar batteries bank, on average, each day
  • If this were a 24V system, it would be 400Ah/day
  • If this were a 12V system, it would be 800Ah/day

 

What Size Solar Battery Bank Voltage?

battery Whenever possible, use a higher voltage battery bank such as 48V over 24V battery banks. (IE: 8 - 6V batteries = 48V battery bank) Your equipment will run cooler which means a longer life for things like refrigerator condensers etc. If your solar panel array is higher than 2,000 watts, we strongly recommend you employ a 48 volt solar battery bank.

 

Rated Solar Batteries Capacity in Ampere-hour (Ah)

battery Battery capacity is the measurement of electrical storage and is often expressed in Ampere-hours (Ah) but also can be expressed in watt-hours (Wh). An Ampere is the unit of measurement for electrical current and means a Coulomb of charge passing through an electrical conductor in one second. The Capacity in Ah relates to the ability of the battery to provide a constant specified value of discharge current over a specified time in hours before the battery reaches a specified discharged terminal voltage at a specified temperature of the electrolyte. The voltage at the terminals is highest at the beginning of a discharge cycle and gradually falls.

As a benchmark, the battery industry usually rates batteries at a “Discharge Rate” C/20 Amperes corresponding to 20 Hour discharge period. The rated capacity in Ah in this example will be the number of Amperes of current the battery can deliver for 20 Hours at 80ºF (26.7ºC) till the voltage drops to 1.75V / Cell. i.e. 10.5V for 12V battery, 21V for 24V battery and 42V for a 48V battery. For example, a 100 Ah battery will deliver 5A for 20 Hours.

How Can You Squeeze More Years (Cycles) Out of Your Solar Batteries Bank?

battery This starts with the design. Minimize the number of strings of batteries by using higher Ah 6V or 2V batteries. Having fewer strings can help distribute the charge equally across the battery bank. Make sure your battery connections are at opposite corners of the battery bank. This will also help equalize the charge and discharge distribution across the battery bank. The last tip involves rotating your batteries within the series strings can help with more evenly distributed charges between cells. Use this opportunity once a year for your Saturday exercise routine and not only will you be in better shape, but you will save some money by extending the life of your battery bank. (Ok, we threw in the exercise part in to see if you were paying attention.)

Solar Batteries Energy Storage, Its About the Chemistry and the Plates.

battery We all know from high school that chemical reactions slow as it gets colder. A cold battery will not hold as much energy as a warmer battery. On the converse, a cold battery will last longer that one stored in an area that is unusually hot. That being said, the larger the surface area of the battery plates, more electrons will be allowed to react at one time creating more amps. Car batteries are thin platted which means there is more surface area for the electrons to react but they draw down very quickly. Deep cycle batteries use much thicker plates and have less surface area so they produce power over a longer time frame.

How Temperature Affects the Storage Capacity of Solar Batteries.

battery Local temperature is a significant consideration when sizing a battery bank for a solar system. The capacity of a deep cycle battery to store energy is reduced in cold temperatures and shortened in high temperatures. Mother earth is a great insulator in high or low temperatures. If you bury the battery bank in the ground, you can increase the battery banks capacity at colder temperatures and lengthen the life of batteries at high temperatures.
