Where batteries are joined
in
parallel
, add the capacities
together, the voltage will
remain the same as each
batteries voltage.
Getting Started Quickly
2 x 12 Volt 150 Ah batteries connected in parallel would have a
capacity of 12 Volts – 300 Ah. This would
not
suit your 24 Volt
LD550-24.
Only use identical batteries when joining batteries together.
How long will my battery last
To work out how long your battery will last follow this basic guide.
This guide presumes commencing with a fully charged battery.
Take the total rating of the appliance being run
1
light globe
25watts
1
20 inch TV
67watts
1 VCR
30watts
Total load
=122watts
Divide this figure (122) by 20 to know the approximate DC current draw
=6.1Amps
To convert this to Ampere hours, multiply by the number of hours used -
Say 1 hour
=6.1Ah
So if we have a 150Ah battery, then with the above example we should have
150 minus 6.1 = 143.9 Ah remaining in the battery.
As a general guide never discharge a battery below 50%. The deeper
a battery is discharged on a regular basis, the less life you can expect
from the battery. See you battery specifications for full details.
If you want to get powered up quickly here are the 11 simple steps.
1.
Familiarise yourself with the details in the first 6 pages on this manual.
2.
Unpack the LD550-24 from the packaging.
3.
Check unit for any damage that may have resulted during transport, if any
damage is evident report this to your supplier immediately.
4.
Make sure the LD550-24 ON/OFF switch (12) is in the off position.
5.
Connect battery positive wire (red) (10) to battery positive or battery fuse.
6.
Connect battery neg. wire (black) (11) to battery negative or battery fuse.
7.
Plug a 230 - 240V appliance into inverter front power point (8) but do not
switch on.
8.
Turn ON/OFF switch (12) to ON.
9.
After 3 seconds LED (1) will begin to flash. If no LEDs light, check for
correct connection to battery.
10.
Turn power point (8) on
11.
You’re away.
