P30L Charge Control Error

Discussion in 'Charge Controllers' started by Jerry Williams, Jan 14, 2018.

  1. I recently hooked up a 100watt solar panel with the P30L LCD 30am Charge control to a bank of batteries on my house boat. The batteries were completely dead when this was hooked up. After two weeks I came back and batteries are still dead & the screen is showing the Sad face Icon on the control. When I start the generator the control shows it is working correctly, but as soon as it is turned off, the "error/abnormal working conditions" code comes back on. Checked on connections and diagrams and everything is wired correctly and all connections are tight. Any suggestions or thoughts? My Batteries my be shot. Would this cause that?

    This is the kit I purchased :
    WindyNation 100 Watt Solar Panel Off-Grid RV Boat Kit with LCD PWM Charge Controller + Solar Cable + MC4 Connectors + Mounting Brackets

    If your batteries were dead when you connected everything up the system can't fix that.
    you need good batteries to start with.
    Or at least showing a charge of 10 volts, even then you may not be able to get much use out of them.
    As batteries age they will hold a charge for less and less time.
