I have (2) 100W Rich Solar panels in series to charge the AC200p. First time i hooked everything up, the input on the bluetti display was showing low amps (1.5 - 2.0). Volts were around 37-41. Input watts would vary between 60-90 on a 1 second interval. Internet told me wiring/connections or controller could be a culprit.
I got a multimeter and ran through each panel while on the ground. Each panel was around 21V/3.5A and when put in series 43.7V/3.49A when tested directly on the panels. Generally
I thought maybe something with my wiring inside the van so the pictures below show the system set back up on the van and the test was at end of my wiring before bluetti connection. The last picture is the bluetti screen. All three pictures taken within 45 seconds of each other. A video would show the bluetti input volts/amps jumping around each second…sometime 5-7 volts. Multimeter was relatively steady reading.
Not sure where to go from here…can’t seem to get the input watts on the bluetti display over 90 or 92 on multiple sunny days, no clouds/shadows. Maybe something with the bluetti I might be missing?
Thanks in advance.
Thanks for following up. Rained yesterday so i got out today to test the charging cable. Slightly overcast. Voltage and amp reading were pretty consistent at the end of the panel MC4 connector (46.8V/2.63A) and at the end of the charging cable 2-pin aviation connection (45.9V/2.54A). I can only post the one picture as a new user it says…this one is voltage at 2-pin aviation.
