Hello
I have a small solar system 4 panels a. 175 Watt the system is connected to a BlueSolar Controller MPPT 100/50. When I look at my monitor I see that my panels deliver 80 Volt, but 0Watt and 0.2 Amper.
My battery monitor BMV 700 indicates that the battery is 100% full with a power of 9.5 volts.
The Phoenix Inverter 12/800 goes right on error. The system is located in the south of Spain
Where's the mistake?
Hola Hilton. I'm presuming freshly installed, not a failure.
The 9.5V is likely correct, indicating flat batts. Why the Phoenix is faulting? You must fix this, don't just leave it..
The 100% SOC won't be right, and the BMV will need a good tune-in. If it's somehow set to control anything, disconnect it's data link.
You'll need a multimeter to check the continuity of all your wiring. Check polarity too, especially of your solar wiring. Depending on your panel specs, you may have 2x strings of panels, so check both strings separately up to where they join together, then at the mppt.
Don't rely on the panel 80V to indicate anything at all. With no A it's meaningless.
Same with the 0.2A (bmv?), it may be just a zero-error, which can be fixed when you sort the real problem.
Sorry if I'm offbeam, comes with assumptions.. Good luck.
Hallo John
Fehler gefunden, <Sicherung zwieschen MPPT und Battery kaputt getauscht jetzt wieder alles OK
Ha, I'm not very worldly, but do have google -
Error found, <Backup between MPPT and Battery broken replaced now everything OK
Good work..
