Note: If an extension cord is used from the inverter to an appliance, limit the extension cord
length to 50 feet or less. Make sure that the cord is properly rated to carry the appliance load.
Extension cords are not to be used as permanent wiring. Instead, use High Output Terminals and
NEC compliant wiring, outlets and installation techniques.
CHARGING THE BATTERY BANK
It is not the purpose of this inverter user’s guide to provide detailed information regarding battery
charging systems. However, the user should try to augment any charging system with either
wind power or solar power. These can continue to operate during power outages and they also
reduce recharge time.
Regular Loss of Commercial Power
If an inverter system is used during commercial power outages that occur daily, configure
the charging system to replace energy during the time that commercial power is available.
Replacement of battery energy always requires more than was taken from the battery
(typically 130 percent). When charging you battery bank, make sure the current received by
an individual battery is within its charge rating. Be sure that the battery is well vented as the
area will likely have accumulations of an explosive mixture of hydrogen and oxygen. Follow all
recommendations for use that are contained in the battery charger manual.

WARNING: THERE IS DANGER OF EXPLOSION� DO NOT CONNECT OR DISCONNECT
CHARGER CABLES DIRECTLY AFTER BATTERY DISCHARGE OR RECHARGE–MAKE SURE THAT
THE BATTERY BANK AREA IS WELL VENTED BEFORE ATTACHING OR REMOVING CABLES�
If the flooded lead acid batteries are used, as examples given in this document, be sure that
periodic checks of battery electrolyte levels are accomplished. Follow battery manufacturer’s
instructions in keeping the electrolytes at the proper level. Be sure to use pure distilled water
when replacing evaporated electrolyte liquid.
Aboard a Vessel or Vehicle
Manufacturer supplied engine driven alternators can usually be replaced with ones that can
continuously deliver higher amperage. This should be done at the outset. Keep the batteries
charging when the vessel or vehicle engine is operating. In the case of a vessel, make sure that
shore power is used to recharge the batteries whenever possible.
Television and Audio Suggestions
Although all inverters are shielded and filtered to minimize signal interference, some interference
with your television picture may be unavoidable, especially with weak signals. However, here
are some suggestions that may improve reception.
• First, make sure that the television antenna produces a clear signal under normal operating
conditions (i.e., at home plugged into a standard 11O/120V AC wall outlet). Also, ensure
that the antenna cable is properly shielded and of good quality.
• Change positions of the antenna cable and television power cord.
• Isolate the television, its power cord and antenna cables from the 12-volt power source by
running an extension cord from the inverter to the television set.
