HOW TO SIZE A DEEP CYCLE BATTERY BANK

If the battery bank is oversized, you risk not being able to keep it fully charged; if the battery bank is sized too small, you won't be able to run your intended loads for as long as you'd planned.

The energy stored in the deep cycle batteries can then be used directly to power DC loads or it can be inverted to power loads. The batteries recommended for RE systems are deep cycle batteries. To ensure you have enough reserve capacity to provide the electricity you need (without running additional generators), invest the time to size your deep cycle battery bank properly. Because of the various conditions affecting battery bank sizing, this process may be one of the more challenging calculations you’ll have to do when planning your RE system.

Before tackling the calculations, start by identifying a few key pieces of information:

Watt/hours of electricity usage per day

Number of Days of Autonomy

Depth of Discharge limit

Ambient temperature at battery bank

ELECTRICAL USAGE

The first thing you’ll need to know is the amount of energy you’ll be consuming per day. Measure starting and running loads

of pumps, refrigeration compressors, electronics, etc. and for what lengths of time. Track this information on a loads list; as you will need it for sizing other components as well. Your final tally should be expressed in Watt-hours (Wh) per day. If you know the kilowatt hours (kWh) per day just multiply that number by 1,000 to determine the Watt-hours per day. (Example: 1.2 kWh = 1,200 Wh)

DAYS OF AUTONOMY

Next, you must determine the number of days of battery back-up that you want to have on hand. In other words, if you are unable to charge your deep cycle batteries by any means, and you still need to draw power, you must provide this additional storage by increasing the size of your battery bank. For solar panel powered systems (PV), Days of Autonomy represents the number of cloudy days in a row that might occur and for which you intend to store energy. Consult a weather website, local meteorologist or even long-term area residents.

If you conclude that you need more then five days of battery backup, you may want to explore multiple sources of electricity generation or backup generator options (like a fossil-fueled generator). If your primary electricity source is wind power, determine the number of days when there is little or no wind. This information can be found in the data you’ve collected using your data-logging anemometer. Hydroelectric turbine systems are unique because they usually operate continuously, and therefore do not require extensive storage. If you’re sizing a battery bank to be used in conjunction with an on-demand fuel-powered generator, the number of days of backup will represent the number of days you wish to go without using your generator.

DEPTH OF DISCHARGE

Another factor to consider is the planned (DoD) of your deep cycle battery bank. Flooded lead acid batteries (FLA), sealed AGM batteries and sealed gel batteries are all rated in terms of charge cycles. A single cycle takes a battery from its fully charged state, through discharge (use), then back to full charge via recharging. The depth of discharge is the limit of energy withdrawal to which you will subject the deep cycle battery (or battery bank). DoD is expressed as a percent of total capacity. The further you discharge a battery, the fewer cycles that battery will be capable of completing. Simply stated, deeper discharge shortens battery life.

It’s recommended that you never discharge a deep cycle battery below 50% of its capacity ; however, many battery manufacturers recommend even shallower DoDs. For off-grid applications, a 25% DoD will extend battery life significantly. On the other hand, if you’re only using the batteries occasionally, as a backup system, you can factor in a DoD of 50% or perhaps more.

TEMPERATURE

Deep cycle battery life and capacity are affected by temperature. Unlike PV modules, batteries perform best in moderate temperatures. In fact, the temperature standard for most battery ratings is 77° F. Cold temperatures tend to reduce battery capacity while high temperatures tend to shorten battery life. For this reason, people in colder climates will often find a place to keep their batteries indoors rather then leaving them subject to outside temperatures. FLA batteries can be destroyed in freezing temperatures. While sealed deep cycle batteries can operate in sub-freezing temperatures, their reserve capacities will be reduced substantially. Identify the lowest temperatures that the batteries will be exposed to and factor this into the calculation using the temperature table (below).

SYSTEM VOLTAGE

By this point, you will have identified your system voltage. This is typically 12V, 24V, or 48V.

CALCULATIONS

Once you’ve pinpointed all these variables, it’s time to calculate the size of your battery bank! Let’s go through the steps below, using the following example system:

A system load of 6,000 Watt-hours per day

Three Days of Autonomy (back up) needed

Planned Depth of Discharge (DoD): 40%

Battery bank ambient average low temperature 60° F.

A 48V system

Step

Process

Example

1

Identify total daily use in Watt-hours (Wh)

6,000 Wh/day

2

Identify Days of Autonomy (backup days); multiply Wh/day by this factor.

3 Days of Autonomy:

6,000 x 3 = 18,000 Wh

3

Identify Depth of Discharge (DoD) and convert to a decimal value. Divide result of Step 2 by this value.

40% DoD:

112,500 / 0.4 = 45,000 Wh

4

Derate battery bank for ambient temperature effect. Select the multiplier corresponding to the lowest average temperature your batteries will be exposed to. Multiply result from Step 3 by this factor. Result is minimum Wh capacity of battery bank:

Temp. in [degrees] F. Factor

80+ 1.00

70 1.04

60 1.11

50 1.19

40 1.30

30 1.40

20 1.59

60° F. = 1.11

45,000 x 1.11 = 49,950 Wh

5

Divide result from Step 4 by system voltage. Result is the minimum Amp-hour (Ah) capacity of your battery bank.

49,950 / 48 = 1,040 Ah
