setup MPPT 150/100

hi guys ive recently purchased a smart solar MPPT VE.Can 150/100

when i first wired it up it had 110V on the array and system voltage was set for 48v the batteries were sitting at 50.5v but no current flowing even tho the bulk charge light was on

i took it back to local agent who tested it on a 24v system as they didn't have an array big enough or enough batteries to setup for 48v system

it worked perfectly

when i got it home i just changed system voltage back to 48v and there is no current flowing

so i retested it here with 110v on the PV array and system voltage at 12v and on one battery and it worked

i then retested it at 24v system voltage with 2 batteries & on same array and it worked

but doesn't work on 48V system

has any one else had this issue

running firmware V3.02

Hi Tony, do you first connect the battery bank to the MPPT ? As it recognizes the voltage to use this way. Connect the batteries, then the solar PVs.

Ask your Victron dealer to test it with a 48V battery. The MPPT might be defective.
