I have a Bluesolar 150/45 - 48 Volts bank - 2 x 250 W solar panels
Something is wrong with it on recent days, charge highly vary up and down and allways been on bulk state.
I made the tests on a shiny day, no clouds. I already check the settings and everything seems to be OK.
Help will be appreciate, I have several bluesolar/smartsolar installations and I never face something like this.
Thanks and regards
