Good afternoon I have 12 x 250 ah Gel batteries on a 48 volt Axpert 2 x 5Kv MKS parallel inverters with 6kw of solar. Currently i have a HA-02 on each of the three banks of batteries, what would the correct wiring of these batteries with balancer Victron are suggesting that you parallel the series bridging of the batteries would this improve the charging and balancing of batteries https://www.victronenergy.nl/upload/documents/Datasheet-Battery-Balancer-EN.pdf

I have changed priority to master and still it beeps...... maybe I must do a full reset of inverters.

Model is RCT Axpert 5k

Please send email address I will forward short video.

Good afternoon, I have two 5kv Axpert inverters in parallel. One of the inverters beeps every 30 seconds. I have turned off all alarms and there are no error codes and yet in continuous beeps every 30 seconds. I have checked fuses to batteries and confirmed the program is exactly the same.

Ahhh ok....will pop down home shortly and change to 40 amps Sent from my SM-G955F using Tapatalk

Would this not be related to setting no 2 to 70 amps per inverter? Sent from my SM-G955F using Tapatalk

Yesterday there were no amps at all only registered around 105 volt at 3 pm. Definitely a software issue. Not seeing the pv voltage. Sent from my SM-G955F using Tapatalk

Definitely a problem already registering 75 volts on PV Sent from my SM-G955F using Tapatalk

System been running like this for over a year with no issues. Sent from my SM-G955F using Tapatalk

All settings are the same as previous post except for the changes you suggested. Two strings of panels. 9 x 300 watt 3 in series of 3 strings 12 x 235 watt 3 in series of 4 strings Come into two fused combiner boxes Sent from my SM-G955F using Tapatalk

I know that's what is so strange. Sent from my SM-G955F using Tapatalk

49.6 volts Sent from my SM-G955F using Tapatalk

The inverter did not switch the panels on this morning. Stayed in bypass on grid all day. I have 6 kw of Pv and on a clear day can produce around 4.4kw Sent from my SM-G955F using Tapatalk

Apologies.......panels did not come on.... Sent from my SM-G955F using Tapatalk

Hi Chris Batteries are about a year old. I did the necessary changes you suggested and my panels did come on this morning stayed in bypass all day. Any suggestions? Sent from my SM-G955F using Tapatalk

Thank you Chris I will give these setting a try. Much appreciated Sent from my SM-G955F using Tapatalk

hi all, please can someone help with the correct programming? I have two 5kva in parallel, 3 banks of 250 amp hour Sonic gel batteries, 6 kw of PV My batteries are not lasting at all anymore get to 50 volts discharge and fall off the cliff. back to grid voltage 48 volt. Bulk charge 58V floating 54V. bulk charge for 2 hours.

Charging each bank of batteries individually to see if this will bring the batteries back. Is it advisable to rotate the batteries in the string? Dave Morley

Good morning I have been trouble shooting my batteries for a while now. Changed back to grid to 48. My batteries will discharge very quickly after reaching 49 volts. This morning I did a load test on each battery and found that all three of the batteries connected to busbar on the positive leg are in a poor state. Less than 10 volt on load lest. I have 12 x 250 amp Sonic batteries. I have changed over to utility Dave Morley
