Why does the PV of LCD display 0 on my PowerTech MP3764?
If the PV value on the LCD display of your PowerTech Controller shows 0 even when sunlight is properly hitting the PV modules, it might be due to a PV array disconnection. Confirm that all PV wire connections are correctly connected and tightened.
What to do if my PowerTech MP3764 Controller is flashing?
If your PowerTech Controller is flashing, it could be due to a couple of reasons. First, it might be caused by battery overvoltage. To resolve this, disconnect the solar array and measure the battery voltage to see if it's too high. Another possible cause is battery over discharge. In this case, you should charge the battery.
