SanjayK Posted September 24 Share Posted September 24 I am seeking assistance with the settings for my Blue Nova BN52V-100-5.2K BP battery. I am currently using a Mecer SOL-IX-5P Inverter. The system operates correctly under normal conditions. However, during power outages that exceed the battery’s charge, the battery does not automatically switch back on when utility power is restored. I have to manually jump-start the battery using the reset button to restore power. I would greatly appreciate any guidance on the settings that might be incorrectly configured to ensure the system operates optimally. Currently, I have no solar panels connected and no BMAC. I am using a single battery. Quote Link to comment Share on other sites More sharing options...

GerhardK83 Posted September 24 Share Posted September 24 According to the datasheet (see the link to the datasheet) the Low Voltage Cutoff for the battery is 48V, https://www.bluenova.co.za/wp-content/uploads/2023/01/BN52V-100-5.2k-BP.pdf Have a look at the setting for Program 29 - Low DC Cut-off Voltage on the inverter the voltage must be above 48V so that the battery does not discharge fully, also email Bluenova support and ask if the battery can communicate with the inverter, also check the settings of Program 26 and 27 and set them according to the voltages in the datasheet. Another option would be to limit the load of the inverter if there is an extended outage so that battery life can be extended or to purchase another battery.that can be used in parallel with the current battery.

SanjayK Posted September 25 Author Share Posted September 25 Thank you @GerhardK83, i will look into that Program 29, just to clairfy, the voltage must be Above 48V (what would you suggest on a 52V Battery). My issue with this whole thing is that, this installation is in the Drakensberg, and I have to travel 300kms to reset the battery.. Quote Link to comment Share on other sites More sharing options...
GerhardK83 Posted September 28 Share Posted September 28 According to the battery datasheet the voltage cutoff voltage is 48V so the inverter low voltage cutoff must be set higher to prevent the battery from draining completely, can't you train someone to reset the battery?
