My Bluesolar MPPT 150/85 ceased correct operation after a small short on the pv side (unfortunately between PV panel fuses and MPPT )
First it showed a warning "inf 21 " then after complete discconnecting no more error messages but now
- current reading is 0 A , but PV current seems to be simply passed through
- measured current from PV is 7 amps ( cloudy ) and output current is exactly identical
- Voltage on panel is battery voltage + approx 0,7 V
- No MPPT function -
Is there anthing likee a fuse or so ?
Anything I can do ?
