WARNING

 

Improper  Battery  

Type  Switch setting   

may damage  

batteries. 

 

WARNING

 

Battery input cables 
must be connected to 
the battery with 
proper polarity to 
avoid damaging the 

inverter.

 

 

Step 6: Connect the inverter to the battery.  

Connect the black, negative DC input cable from the quick connector to the  battery 

negative (-) terminal. This battery negative terminal is usually where the battery negative 

connects to the engine block or frame. Connect the red, positive DC input cable from the 

quick connector to the in/line fuse near the battery  positive (+) terminal. This battery 

terminal is usually connected to the DC  electrical system at the load side of the Battery 

                        disconnect Switch. 

Step 7: Select Load Demand  option. 

Select Load Demand option if desired, using the proper switch position on the  front panel 
Setup Switch. With Load demand ON, the inverter conserves battery  energy and operates only 
when a load greater than 5 Watts is applied. 

Step 8: Select battery type. 

The charger is capable of charging both gel and flooded lead acid batteries. Select the 

battery type using the Setup Switch on the front panel.  

Step 9: Select the charging rate.  

In the  high position the  charge  is 55 Amps.  In the low position the  output is  15.0 Amps. 
We  recommend  the  low  position  as  the  best  selection  when  two  (group  31  or  smaller) 

batteries  are  used.  Charging  at  too  high  of  a  rate  for  a  given  battery  will  damage  the 
batteries. 

Step 10: Connect the AC loads.  

Connect the  AC  loads to the  inverter GFCI  receptacle. Any time  AC power  is  applied to the 
AC input (shore/utility power), it will pass through this GFCI receptacle. 

Step 11: Verify installation. 

Verify all connections are tight and secure for maximum performance.

Inverter 

Light Action 

Description 

  

Steady Green Light . 

Inverter is On and operating 

  

Single Blink Green Light 

Inverter circuit is Off. Shore power is On and supplying AC power to the 

  

 

AC loads. The inverter will turn On and supply the load if shore power is 

  

 

lost. 

  

Double Blink Green Light 

Inverter circuit is Off. Shore power is Off. The inverter is waiting for a load 

  

 

greater than 5 watts to be turned on. 

Battery Low 

Light Action 

Description 

  

Solid red 

Inverter is On and the battery is almost too low to operate the inverter. 

  

Blinking Red 

 
 
The inverter is Off. The battery voltage dropped below 10.5 volts DC and 
the inverter shut itself Off. Once shut off, the batteries must be recharged. 
Then, the inverter On/Off switch must be cycled to reset the unit.
