July 31, 20232 yr HI All. Hope everything is going well. I have a Mecer Axpert 3KVA Inverter. Using 2 X Hubble S120 Batteries in series. The problem is when load shedding comes the inverter continues to supply power for about 5 seconds then stops. Both input and output display 0V. Battery Logo remains and shows full. After load shedding input displays 240V, a few seconds later 240 on output and power is back. Has anyone else had this problem before? Regards Ryan

Better to use the down arrow while the grid is on. Press it a few times until it shows you the battery voltage. You can also try to get this voltage showing and then while looking switch you grid off and see if you can spot that this reading goes down in the 5sec before it switches off. Lastly ignore the display readings and read the battery voltage with a multimeter. Then report back. May be your S120 are just not charged.
August 1, 20232 yr Author Hi Scorp007. Thanks for replying. Thanks for your input. I will run some tests tonight and come back to you. Regards Ryan
August 4, 20232 yr Author Hi Scorp007 Took a bit long but I managed to check. Used a multimeter. Battery Voltage 26.9V. I kept monitoring, then turned the power off. Voltage didn't move. Stayed on the 26.9V Thanks for helping. Regards

At that nearly fully charged or fully charged the inverter should work up to the back to grid level as set on the inverter. That's how mine works up to my 24V setting to cut out if there was no grid.
August 5, 20232 yr Author Thanks. Anyone know where I can have it repaired in the East Rand? Mustek want to replace the mainboard for R5900.
