It has come to our attention that some of our IPS boat builders use / wish to use a common start battery
array for IPS installations. The following information is aimed at clarifying the differences between sep-
arate (twin/double) battery arrays (hereafter referred to as 'separate battery arrays') as opposed to a
common battery array.
In the installation literature Volvo Penta draws attention to the fact that IPS installation with a common
start battery array is NOT allowed. (Note: The sensor cable must be connected to the start battery array).
IMPORTANT! Common start battery arrays are not permitted for ISP installations.
The difference between separate battery arrays and a common battery array is described in the following
text:

Separate start battery arrays

1. Starter motor
2. Auxiliary battery 1
3. Start battery
4. Starter button
5. Breaker
One array of start batteries (one or more parallel-connected batteries) is used for each engine.
This solution provides system redundancy and is moreover the optimum solution for IPS.
This arrangement must be used for IPS.
