Connecting the Batteries 

Batteries of even very small capacity can deliver very high currents, which can cause injuries 
or fire. Therefore, battery connections should be done with caution.  

To optimise the service life of the batteries, the battery charger output voltage varies with 
temperature.  

 

Note:

 In the event of mains power failure, the battery charger circuit will protect the batteries 

from full discharge by disconnecting them when they reach below 19v. When the mains 
supply is restored the batteries will be automatically reconnected. 

Note:

 If mains power is connected before the batteries, the panel will show a Power Supply 

fault for up to 1 minute until the monitoring cycle has finished polling. This is normal. If the 
fault does not clear after 1 minute, check connections. 

Battery Charging Voltage Checks 

The battery charging voltage is factory calibrated to 27.3VDC +/- 0.2V at 20

°

C. This should 

not normally require adjustment. Where battery problems are experienced, the following 
information should be considered: 

a)  If a battery is disconnected from the charger, no voltage will appear on the output 

leads or terminals, due to intelligent battery controls. 

b)  Check the power supply voltage at the PSU 28V and 0V supply output terminals. 

With the batteries disconnected the voltage should be 28.0VDC +/- 0.2V at between 
11°C and 40°C. 

c)  To test the batteries, turn off the mains and see if the system will run on the 

batteries. Check the battery voltage, which should be 26.8V for a good battery or 
22V for a flat battery.  

d)  When the panel is re-charging a low battery, it should be possible to see the voltage 

across the batteries increase gradually. If this is not occurring, the batteries or the 
panel may be faulty.
