Deon_J Posted April 8, 2020 Share Posted April 8, 2020 Hi, my inverter is displaying a code I dont know and cant find an explanation of, can someone please help. The inverter is still working 100% Quote Link to comment Share on other sites More sharing options...
Andries Posted April 8, 2020 Share Posted April 8, 2020 Hi,when did this happend? does your inverter perform normally? there is no electrical burn smell? when I check on my research you may blown a diode if I am not mistaken Quote Link to comment Share on other sites More sharing options...
Coulomb Posted April 8, 2020 Share Posted April 8, 2020 (edited) That's not an error, it's a ⚠ warning. Also, it's "Eq" (for EQualisation) not "E9". If you don't expect equalisation, check your settings, numbered up in the thirties. It's there because when you use equalisation on flooded lead acid batteries, the battery voltage is usually quite high, and you could be losing water from your battery cells. But if you are using the equalisation settings to work around the premature float bug, you should be using your standard bulk/absorb voltage, so it should be safe to ignore.

[email protected] Posted April 9, 2020 Share Posted April 9, 2020 The "E9" Is the indication that you're inverter/solar - PV is busy with the cycle of battery equalization. Equilization will occur on a delay cycle base which depends on the setting registers 37 interval period, 35 time duration, 36 time period.

[email protected] Posted April 9, 2020 Share Posted April 9, 2020 there is nothing wrong with you're unit at all, hope the previous information has helped. Should you not require you're system to execute the routine, you could disable it by changing the settings. This all depends on the type of batteries you are using as the power storage base.

Deon_J Posted April 9, 2020 Author Share Posted April 9, 2020 Hi, thank you for the feedback. I must say its a huge relief. Just a follow up question I have Lithium ion pack, should eq be on? Quote Link to comment Share on other sites More sharing options...
Andries Posted April 9, 2020 Share Posted April 9, 2020 (edited) So sorry I have mistaken your E9 with an 09,apologies. Lithium battery does not need equalization and you should turn it off,battery equalization is only use for lead-acid type batteries Edited April 9, 2020 by Andries Quote Link to comment Share on other sites More sharing options...
Deon_J Posted April 9, 2020 Author Share Posted April 9, 2020 Thank you, will make the change. Quote Link to comment Share on other sites More sharing options...
Coulomb Posted April 9, 2020 Share Posted April 9, 2020 (edited) 47 minutes ago, Andries said: Lithium battery does not need equalization and you should turn it off Generally true. However, it can be used as a workaround for the premature float bug, especially in models where no patched firmware is available. In these cases, the equalisation voltage (setting 34) would be set to the same (or very nearly the same) as the bulk/absorb battery voltage (setting 26). If setting 34 is significantly higher than setting 26, then this is indeed bad for your non-lead-acid battery, and you should turn it off by changing setting 33 (battery equalisation enable/disable) to EdS (disable). [ Edit: when this is done, none of the many other equalisation settings have any effect, so that's the only one you need to change. ] Edited April 9, 2020 by Coulomb Andries 1 Quote Link to comment Share on other sites More sharing options...
Helgard. Posted April 13, 2020 Share Posted April 13, 2020 Can this unit pump elect back into the grid? Quote Link to comment Share on other sites More sharing options...
