How can I compare a battery bank?
A battery bank is compared with other battery banks by the amounts of available voltage and amperage in each. On this page you will see examples of battery banks where the voltages and amperages are listed, according to what our supplier has told us.
Example:
As an example of small household item capacity: First you need to decide how much voltage and amperage that you need. The common household voltage is 110 to 120 volts for small items, so we say for calculations 120 volts. Then you need to decide how much amperage that you need. The common household breaker-box has a 100 amp rating for small items, so we say 100 amps. At this point you can go directly to the charts below and figure what you need, within reason, and we say "within reason" because the charts are estimates and can be changed by adding or subtracting batteries from the charts. Let's say that (for example) someone needed 120 volts and 100 amps, using Table BBP04 should be able to handle that. We multiplied the voltage (120 volts) by the current (100 amps) and got 120 x 100 = 12,000 Watts (or 12kilowatts, or 12KW, or 12 kilo volt amps, or 12 kva, or 12 KVA). How long do they want that backup supply to last? Let's say 4 hours is sufficient. That is a full load of 100 amps drawn at a continuous 120 volts for 4 hours. That would be row number 6 of that table,
