Hello!
Second Victron MPPT suddenly got error 21 current sense issue after updating FW from v1.59 to 1.64 and also after downgrade to 1.61.
Does anyone have the 1.59 fw or ideas what happened?
Thanks!
Have you looked up the error code here and resoltion? The code does not auto reset and requires you to disconnect the MPPT as described.
Hi!
Yes, i have done that multiple times and tried 12 and 24V on the batt side.
Device reset to defaults, setting the batt voltage…
Powered from the batt side the error takes about 30 seconds to appear. Adding power to the PV input all it does is clear the “Why is the charger off” message until the fault appears.
Either the unit got damaged in shipping or the FW update changed something (doubt it)
Meh, never mind, I’m sending it back!
Hi, I have this problem too!
Error 21 - current sensor problem
Hi, I’m trying to install my bluesolar 150/35. I wired the battery cables correctly first and then the PV, I immediately noticed that the blue LED did not flash with the battery cables connected, then by connecting the PV cables the blue LED turned on steadily and constantly and the app on the smartphone started to “see” the regulator. The screen gave me PV 2.3 w, battery voltage ok and current 0, this morning I received a notification on the app with problem no. 21. What can I do? Thanks to anyone who can help me. Francesco
Disconnect pv, check the voltage on the battery terminals of the mppt.
I guess it’ll be zero…

hi ludo thanks for the reply, actually in the battery connectors without PV I read the correct battery voltage (25.3)
Is this a bluesolar or a smartsolar ?
Check this for reference…
Blue Solar
How do you connect the smartphone?
yes the application only connects when I connect the PV
How ??

Ok.
I’d disconnect the battery terminals and check if they really connect to the mppt.
And try a factory reset with the connect app
Otherwise the internal fuse in the mppt failed…
I’ll try now, do you know if the fuse can possibly be replaced?
sorry but where can I find the factory reset on the victron app?

No, sorry, but i guess not.
GRAZIE domani mattina provo!
