PROsine Inverter Owners Manual
SEALED FLOODED BATTERIES:
DELCO: Voyager
IDENTIFYING FEATURES:
Vents which look like they are removable but are not.
Sold as Maintenance Free at attractive prices.
ADVANTAGES:
Less maintenance required than Flooded. No need to
fill with water. Less expensive.
DISADVANTAGES:
Less resistant to over-charging because they consume
water but cannot be refilled.
RECOMBINANT FLOODED (SEALED)
BATTERIES:
HAWKER ENERGY: Genesis
OPTIMA: Yellow Top
GNB INDUSTRIAL: Evolyte
IDENTIFYING FEATURES:
Vents are often concealed. Sold using the following
phrases: Recombinant, Valve Regulated, Maintenance
Free, Starved Electrolyte.
ADVANTAGES:
Require no maintenance. Non-spillable
DISADVANTAGES:
Can be damaged by equalization. Generally more
expensive.
GEL SEALED BATTERIES:
SONNENSCHEIN: Prevailer
WEST MARINE: SeaGel
IDENTIFYING FEATURES:
Sold as either Gel or Gelled Electrolyte batteries.
ADVANTAGES:
Require no maintenance. Often can be used on their
side. Non-spillable. Low self-discharge. Less damage
from being left discharged.
DISADVANTAGES:
Damaged by equalization. Generally more expensive.
7.2 Battery Size
Just as important as the type of battery selected for use
with your PROsine Inverter is the subject of battery size
(capacity). There are a number of different standards
for rating battery capacity. Automotive starting batteries
are normally rated by cranking amps. This is not a
relevant rating for continuous use. Deep cycle batteries
are rated either by reserve capacity in minutes or by
amp-hours.
Battery reserve capacity is a measure of how long a
battery can deliver a certain amount of current - usually
25 Amps. For example, a battery with a reserve capacity
of 180 minutes can deliver 25 Amps for 180 minutes
before it is completely discharged.
Amp-hour capacity is a measure of how many amps a
battery can deliver for a specified length of time - usually
20 hours. For example, a typical marine or RV battery
rated for 100 Amp-hours can deliver 5 Amps for 20
hours. (5 Amps x 20 hours = 100 Amp-hours)
You can expect performance from the inverter to suffer
with the use of a small, low amp-hour rated battery (eg.
50Ah). Even if your battery is in excellent shape and
fully charged you will likely experience poor surge power
performance and unsatisfactory operating time with
anything but a small AC load. Statpower recommends
a minimum battery size of 200Ah for moderate loads
(less than 1000W) and greater than 400 Ah for heavy
loads.
To determine how large a battery or battery bank you
require for equipment running from the inverter, simply
add together the power requirements for all electrical
devices that you will be running multiplied by their
approximate running times in hours between battery
recharges. Each device will be rated in either watts,
volts and amps, or VA. For this calculation, all three of
these ratings are equivalent (i.e. volts x amps = watts =
VA). The following example, based on battery
recharging every three days, illustrates the calculation:
1
Power Consumption x Operating Time
Convert the watt-hours to amp-hours by dividing total
watt-hours by 10:
1495 watt-hours/10 = 149.5 amp-hours
A 150 Amp-hour battery is required to supply enough
power for the above loads, and become completely
discharged. Ideally, you normally want to discharge your
battery to only 50% capacity, so for the above loads,
you would require about 300 amp-hours of battery
capacity.
When sizing your battery, be generous. More capacity
is better since you will have more reserve capacity, and
your battery will not be discharged as deeply. Battery
life is directly dependent on how deeply the battery is
discharged. The deeper the discharge, the shorter the
battery life.
As your power requirements increase, to obtain sufficient
battery capacity, you may need to use more than one
battery. Two identical batteries can be connected positive
to positive and negative to negative in a parallel system
that doubles the capacity and maintains the voltage of a
single battery. It is not recommended to connect batteries
from different manufacturers or with different amp-hour
ratings or with different battery electrolytes in parallel.
Decreased battery life may result.
