Run setup in a lab, use bench PSU to mimic PV behaviour (set PV limiting parameters as curr and volt of PSU). Check if 1040 tracks PSU settings and runs around that point (PSU mode will switch countiniously between CC CV mode). Manually charge batter...

There`s actually couple of designs available with PCB.https://docs.rs-online.com/c85f/A700000006572356.pdfhttps://www.farnell.com/datasheets/1817171.pdfhttps://static5.arrow.com/pdfs/2012/1/1/0/33/7/806/st_/auto/cd00292052.pdfBoth have supercap at th...

Oh I see its a sketch refference without PCB and waveforms. Ok, if you tried to just copy ref to your borad you really missed bulk cap I talking about, C6=47uF on L6924 part. Still I recomend trying 100-1000uF. L1 is actually 22uH (reads lower), and ...

Hello!First question, what`s a purpose of IC2? It supposed to be a charger, but 1040 poses a battery charger with constant current output already.Even besides that, current sense input may be shorted to ground, if not used. R29 with 0 Ohms is decisio...
