How to measure voltages in SBR-battery system

Applicable to SBR series

Updated over a week ago

This guide describes, how to measure DC-voltages in SBR-battery systems to ensure correct installation and support trouble shooting. The nominal voltage of one battery is approx. 64V DC.

On the battery-base are two connection/measurement points.

  1. Connection point for the switch gear.

  2. Connection point for battery module.

On the battery module, are two connection/measurement points.

1. Upper connection terminal. (On top of the battery module)

2. Lower connection terminal. (At bottom of the battery module)

To check the voltage of a single battery module, measure the voltage between plus (top terminal) and minus (bottom terminal), as shown on the pictures below)

To check the voltage of the battery-base with battery module connected, please measure the voltage as shown on the picture below. If there is more than one module connected, the voltage is higher according to the amount of the connected battery modules.

Before stacking up new battery modules, make sure, there is max. 5V difference between the modules.
