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, there is no relationship between cold
cranking amps (CCA) and ampere-hours (AH).
For example, if a 20 AH battery is discharged at a 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 13.4 volts (fully charged) then drops to 10.7 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). In heavy battery
discharge applications, double the estimated Amp Hour rating and configure
batteries to support this capacity. If the batteries are frequently charged by an
alternator, the Amp Hour rating of the battery may be reduced.
CONFIGURING THE BATTERY BANK
Batteries that are used indoors or inside a vehicle or vessel, should be deep-cycle,
sealed lead acid batteries.
NOTE: It is important that for any inverter installation to battery protection fuses.
Battery fuses are added to the positive (+) battery cable as close as possible to
the battery bank’s positive terminal. The fuse amperage rating must be sized to
allow simultaneous operation of all the AC appliances to be powered, plus 20
percent safety factor. Fuses are very important to protect equipment, batteries, and
personnel. The fuses protect against battery explosion if the cables that connect to
the inverter accidentally short.

WARNING—Exploding Batteries!!
Exploding batteries can spray molten lead, hot sulfuric acid, and other metal,
and plastic fragments. Batteries that are charging or under high discharge
rates produce explosive hydrogen gas into the surrounding area. Be safe–fuse
the battery bank and make sure the batteries are properly ventilated.
DC CABLE GAUGE
Minimize cable losses by using the thickest wire available and the shortest practical
length.
Measure Round Trip (RT) cable distances in feet. Round Trip cable distance is
battery to inverter and back to battery. If the application is in a vehicle with engine
operating, use the supplied cables for round trip distances up to 5 feet.
Use a recommended ANL fuse and Fuse holder. Fuse at 125 to 150 Amps. ANL
are quick acting and sealed so they do not spark when they blow. Place fuse no
more than one foot from the Positive (+) terminal of the battery.
RT Length Up to 2 Ft 3-4 Ft 5-6 Ft 7-9 Ft 14-16 Ft
AWG 6 4 2 0 0
If the inverter and the battery are positioned within four feet of each other, a
minimum of 7AWG insulated copper wire should be used to make the connections.
If the distance is longer than 32 inches (2.6 ft), heavier wire will be required.
CONNECTING THE INVERTER
Loose connections will result in a severe voltage drop that can cause damage to
connectors, conductors, and insulation and can cause sparking. Reverse polarity
connection will blow the fuses in the inverter and can permanently damage to the
inverter. Damage caused by reverse polarity will void the warranty.
Installation Procedure:
1. Mount the inverter in a secure location. If the inverter is to be mounted on a
wall, mount it horizontally. Make sure that the front and rear of the inverter has
free air flow.
2. Make sure the cables are the proper gauge and have the fuse holder as close
to the battery bank’s Positive (red) terminal.
3. Install the fuse in the Positive (red) cable.
4. Make sure the ON/OFF switch located on the front panel of the inverter is in
the OFF (O) position.
