Connecting The Inverter - Wagan Tech Slim Line 2294 Guide D'utilisation

• Use of DC appliances and compliance with turning off unnecessary DC
loads
• If the inverter is installed in a vehicle and the alternator output in Amps
cannot supply enough current for the inverter, additional batteries are
required to supply the required current.
DERATING THE BATTERY BANK
Most lead-acid batteries have a rating expressed in amp-hours (AH). The most
common rating of AH is at the "20-hour rate".
NOTE: Despite several Internet explanations, here is no relationship
between Cold Cranking Amps (CCA) and Ampere Hours (AH).
For example, if a 20Ah battery is discharged at an 1 amp rate, is will take 20
hours to discharge that battery. The terms "charged" and "discharged" relate to
actual battery voltage. This means that the output voltage of a nominal 12 volt
battery starts at 13.2 volts (fully charged) then drops to 10.6 volts (discharged).
If the load on the battery causes the battery to discharge faster than the 20 hour
rate, the capacity (AH) of the battery is measurably reduced (derated). Derating
is a major run time factor. Some benchmarks are as follows:
• If an 100 Ah Battery is discharged at 100 Amps, the battery capacity acts
like a 56 Ah battery.
• If an 100 Ah Battery is discharged at 200 Amps, the battery capacity acts
like a 32 Ah battery.
Again, both high discharge rates are faster than the 20-hour rate so battery
capacity seems lower.
INSTALLATION
Safe installation requires that a Battery Protection fuse is installed within one foot of
the positive (+) battery Terminal [red]. Use ANL marine fuses or equal because they
do not spark when they blow. Use an appropriate fuse holder for the fuse. ANL
fuse holders can be mounted so they do not move in a vehicle or vessel.

CONNECTING THE INVERTER

Loose DC (battery) connections will result in a severe voltage drop that can
cause damage to connectors, conductors, and insulation and can cause
sparking. Reverse polarity connection can permanently damage to the inverter.
Damage caused by reverse polarity will void the warranty.
