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 110/120V 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.

• Coil the television power cord or install a clamp-on ferrite choke (available from electronic

parts suppliers).

Note: Some inexpensive audio systems may have a slight “buzzing” sound when operated with

the inverter. This is caused by insufﬁcient ﬁltering in the audio system. The only solution to this

problem is to get a sound system with a higher quality power supply.
