  Series battery connection: When using multiple batteries in series, all 

batteries must be equal in voltage and amp hour capacity, and the sum 

of their voltages must be equal to the voltage of INVERMAX Nominal 

Input Voltage (Apply to INVERMAX 1500/2000) 

 

 

z

  Parallel battery connection: When using multiple batteries in parallel, 

each battery’s voltage must be equal to the voltage of INVERMAX 

Nominal Input Voltage (Apply to INVERMAX 500/1000 extend the 

backup time)
