Derating Curve Lead Acid Batteries
Continuing with the example above: The 150 amp load will need to run for 10 hours, so we begin
configuration with a 1,500 AH battery. If the vertical is 1500 and the horizontal is 150 amps the
percentage of load on the battery is 10 percent. The curve shows that the 1500 AH is derated to
90 percent of maximum. This means that the battery will have to be 1,650 AH for the full 10 hour
run time. It is important to add some extra battery capacity, to compensate for battery age.
CONFIGURATING THE BATTERY BANK
Six volt, 220 AH deep cycle “golf cart” batteries were selected for these illustrations because they
are generally readily available and relatively inexpensive. With regular recharging they have a
relatively long life. These batteries are “flooded” and vented types; they freely vent hydrogen and
oxygen while under charging and heavy discharge. They must be vented to outside air to prevent
accumulation of explosive gases.
If the batteries are to share a compartment with the inverter, then use sealed lead-acid batteries
that are available in gel cell and AGM varieties. Both sealed battery types will not spill liquid
electrolyte (acid) when overturned or punctured.
