• Charge level of the batteries (between use, chargers have to be
able to fully charge the batteries)
• Temperature of the batteries (colder batteries provide fewer amps)
• Age and condition of the batteries (older batteries lose capacity
(amp hours)
• Compliance with turning off unnecessary AC and DC loads.
If there is any doubt about sizing the battery bank, it is safe to over
estimate the amp hour requirements of the battery bank.
Note:
The type of batteries you use to power your high power inverter is important.
Operating a high-power inverter will routinely discharge batteries and they will
require frequent recharging. Batteries used to start engines are not designed
to repeatedly charge and discharge. PowerBright
TM
recommends using “deep-
cycle” or “marine” rated batteries.
Cable Gauges
When connecting the inverter to a battery bank use the thickest stranded
insulated copper wire available in the shortest length practical. If the inverter &
the battery are positioned within 4 FT of each other, a minimum of #8 gauge
wire should be used to make the connections. When the distance between
inverter & battery bank is 4-6 FT, a minimum of #6 gauge wire is required.
Mounting the Inverter
Your PowerBright
TM
inverter should not be mounted under the hood of a vehicle.
If installing in a vehicle, choose a dry, cool, ventilated area closest to the battery
as practical. Before drilling any mounting holes, make sure that there are no
wires, fuel lines, or tanks directly behind the surface to be drilled.
To mount the inverter:
1. Inverter ON/OFF switch must be in the OFF position.
2. The inverter should be mounted horizontally.
3. Position the inverter against the mounting surface and mark locations of the
mounting screw openings.
4. Remove the inverter and drill four mounting holes.
5. Fasten the inverter to the mounting surface using corrosion-resistant fasteners
sized #10 or larger.
