3.0 Setup

Parallel connection – batteries connected in parallel (positive to positive,

negative to negative) increase the AHr capacity of the battery bank, but

the voltage remains the same.

Example: A 12-volt battery bank with three 12-volt batteries that are rated

at 125 AHrs each. Each of the positive terminals are connected together and

each of the negative terminals are connected together (i.e., connected in

parallel). The AHrs of each battery connected in parallel are added together

(125 AH + 125 AH + 125 AH = 375 AH), but the voltage of the battery bank

stays the same (12 VDC).

Series connection – batteries connected in series (pos. to neg.) increase

the voltage of the battery bank, but the AHr rate remains the same.

Example: A 12-volt battery bank with two 6-volt batteries that are rated

at 220 AHrs. The positive terminal of the fi rst battery is connected to the

negative terminal of the second battery (i.e., connected in series). Since the

two 6-volt batteries are connected in series, the voltage of the batteries are

added together to produce 12-volts (6 VDC + 6 VDC = 12 VDC), but the

amp-hour capacity of the battery bank does not change (220 AH).
In battery banks where you have batteries connected in series and in parallel,

the rules are the same. The batteries connected in series are referred to as a

‘series string’ and the amp-hour capacity doesn’t change. Each series string

is connected together in parallel to increase the amp-hour capacity. Add the

amp-hour capacity of each series string connected in parallel to determine

the total amp-hour capacity of the battery bank.

SETUP: 04 Battery Type – This setting selects the battery type, which

determines the battery charge profi le and ensures the batteries are

receiving the proper charge voltage. The fi xed voltage settings are:

fi xed when using the GEL, Flooded, AGM1, or AGM2 selections, but can

be adjusted if using the CC/CV or Custom selections.
Default setting: Battery Type = Flooded
Range: AGM1, AGM2, Flooded, GEL, CC/CV, Custom
◊ Battery Type (GEL, Flooded, AGM1, or AGM2) – When the bat-

tery type selection is GEL (for Gel batteries), Flooded (for liquid lead acid

batteries), AGM1 (for Lifeline AGM batteries), or AGM2 (for East Penn/

Deka/Discover/Trojan AGM batteries), the charge voltage level for the

Absorption, Float, and EQ Charge modes are fi xed and shown in Table

3-1—depending on the battery type selected and the nominal inverter

battery voltage
