Hi I have installed a panel and MPPT 75/10 on a Motorhome it has work fine for the last month. I am now in Portugal and after a electrical storm the 10A fuse had blown. I fitted new fuse but now system only shows 12 ish solar volts (before 25 ish Volts) the blue light is just flashing and no charging is happening. if I remove the fuse the solar volts show about 24-25 volts.
Please Help
