Steve Posted January 10, 2020 Share Posted January 10, 2020 Hi can anyone please help l have an AXpert 5000 and it doesn’t seem to charge from the grid when the batteries are flat also there are 2 inverters in a pair and one has ( S L ) in the middle of the screen at the top and the other has (H S ) or ( H 5 ) many thanks Steve Quote Link to comment Share on other sites More sharing options...

Check settings 12, 13, 29 (ensure that setting 29 is at least 2.0 V less than setting 12). Also setting 16 should be SNU or CUt (might be called something different on your model, there are many Axpert 5 kVA models). Quote also there are 2 inverters in a pair and one has ( S L ) in the middle of the screen at the top and the other has (H S ) or ( H 5 ) That's normal for paralleled inverters. One is a SLave, the other is the MaSter; they can't show an 'M' in 7 segments so they show a 'H' instead. Steve 1 Quote Link to comment Share on other sites More sharing options...

Perhaps cso is the better option? Just a thought. Quote Link to comment Share on other sites More sharing options...

Sorry, I rarely fiddle with the actual settings these days; Node Red does that for me, and uses more user-friendly terms. Quote Link to comment Share on other sites More sharing options...
Fazil Posted January 11, 2020 Share Posted January 11, 2020 What is node red? Pls share info on that Quote Link to comment Share on other sites More sharing options...

It runs on a BeagleBone Black (similar to a Raspberry Pi). Here is one of my screens, shrunk: Edit: the above is all custom software, based on a home-made battery management system (LyteFyba). It doesn't come "out of the box" like that. Edited January 12, 2020 by Coulomb SYC, ibiza and Steve 3 Quote Link to comment Share on other sites More sharing options...
