Hello coulomb I have AGM batteries and today I left it at USB mode and in fact it turned on at low DC warning which is 46v. Cutoff set to 44. It turned off at around 51v. Set to 20amp charging with utility. At around 7am I heard the generator turning on and off several times for seconds and so I changed to SBU with the phone and it stopped. If I let it in SBU mode the batteries will take forever to start charging, the generator is working for nothing (for bypass like 200w or so) In USB it charges fast at 20 amp as set. So somehow I think we can use that USB mode and play with the battery settings whoever must figure out what's causing it to turn on and off several times for seconds. Also what I notice is that when only utility is charging the batteries, the battery voltage increase very fast, same happens when discharging. Thank you for your replies coulomb and Scorp

Hello guys, can anyone lead me in the right direction? Tonight was tough... Affffr 😪

Today generator started at around 7h30 am, no battery charging at all. SBU mode Solar and utility selected as charging option

I have it set like this Back to grid 46V Back to batteries 51v

Hey Scorp, I use the dry contact on the NO position. In SBU mode it starts and stops with no issues there...

Hello guys, I'm new around here and I've been reading the forum for a while now. Sorry If my English is not perfect. I'm building my own house, and I am completely off grid therefore 100% dependent on my solar system. That beeing said I have 8 x 545w panels Axpert max 7200 inverter 8x 250ah batterys Hyunday diesel generator as backup. What is happening to me is that in order for the automatic startup of the generator works, the inverter have to be in SBU mode. But in SBU mode the charging of the batteries work very bad, or don't work at all which cause the generator to stay on for long periods. If I set USB mode, the charging works as it should which is set to 30A for utility, but the auto start doesn't... Same applies to SUB. I've read in the forum that it might be a firmware related issue but I am kind of scared to update it because me and my family, we are completely dependent on the system and I'm afraid I mess something up. Can anyone point me or guide me the right way? Firmware version 45.07 Firmware version 2 12.06 Thank you in advance, if I can update something that can help you to help me let me know.
