Installation

1) The Battery Balancer(s) must be installed on a well -ventilated vertical surface close to the batteries (but, due to possible corrosive gas ses, not above the batteries !)

2) 2) In case of series -parallel connection, the midpoint

interconnecting cables must besized to at least carry the current that arises when one battery becomes ope n-circuited.

- In case of 2 parallel strings: cross section 50% of the series interconnecting cables.

- In case of 3 parallel strings: cross section 33% of the series interconnecting cables, etc.

3)  If required: first wire the alarm contact and the alarm reset.

4)  Use at least 0,75 mm? to wire the negative, positive and midpoint connections (in this order).

5)  The balancer is operational.

When the voltage over a string of two batteries is les s than 26,6V the balancer switches to standby and all LEDs will be off.

When the voltage over a string of two batteries increases to more than 27,3V (during charging) the green LED will turn on, indicating that the balancer is on.

When on, a voltage deviation of more than 50 mV will start the balancing process and at 100 mV one of the two orange LED s will turn on. A deviation of more than 200 mV will trigger the alarm relay.

What to do in case of an alarm during charging

In case of a new battery bank the alarm is probably due to differences in initial state-of-charge. If the difference between the lowest and highest battery voltage reading is more than 0,9V: stop charging and charge the individual batteries or cells separately first, or reduce charge current substantially and allow the batteries to equalize over time.

 

If the problem persists after several charge-discharge cycles:

a) In case of series-parallel connection disconnect the midpoint parallel connection wiring and measure the individual midpoint vol tages during absorption charge to isolate batteries or cells which need additional charging, or:

b) Charge and then test all batteries or cells individually or:

c) Connect two or more battery balancers in parallel (on average one balancer will take care of up to three parallel 200 Ah strings).

 

In case of an older battery bank which has performed well in the past, the problem may be due to:

d)  Systematic undercharge: more frequent charging needed (VRLA batteries), or equalization charge needed (flooded deep cycle flat plate or OPzS batteries). Better and regular charging will solve the problem.

e) One or more faulty cells: replace all batteries.
