New installation, need help.

Discussion in 'Installations' started by PrairiePounder, May 4, 2017.

  1. Hello I just recently purchased a 200 watt solar panel combo kit, with the charge controller, and a 1000w erayak inverter.

    So it's all hooked up, including the inverter to the battery posts, not the load circuit. I am getting the smiley face on the charge contoller, indicating normal operation. I have the panels mounted according with my location, at a 45 degree angle. But I am only receiving 0.2 A from the panels, on a clear and hot day. I have reset the controller several times by holding the middle button, and it even jumps up to .5A - .7A when I do this but immediately goes back to .2

    I have checked every single connection.

    Any help would be greatly appreciated

    What kit do you have?
  3. Hello tom, I purchased the WindyNation 200 Watt 12/24V Polycrystalline Solar Panel Complete Kit with LCD Solar Controller, copy and pasted as you can tell.

    My aspirations were maybe running a deep freeze, my fridge, my 4k tv and security system, all off of the panels.
    I have one
    35AH 12V deepcycle, new, just to get started, will be adding several more after it is an established system.

    Hard to say. Panels for the controller can be series or parallel wired. With that setup.
    I did not see it but the Renology looks and has same functions.
    They say not to hook panels up until after the battery is hooked up or you could damage the unit.
    also make sure battery is not hooked up in reverse. Says it will not damage it but it will not work.
    Also go thru screens and make sure battery voltage is right.
    Also battery has to be over 10.6 volts or it will not charge.
  6. Right right, it's all hooked up 100% textbook perfect.

    Here's my latest development:

    It is still saying 0.2 A coming in, but over the past few days, the amps per hr, Ah have increased from 0000 to 0015Ah with no differance in the battery, still saying two bars outta 5.

    What voltage are you reading on the PV terminals of the controller?

    If you do not measure between 16 and 19 volts, please check all connections between the panel array and the controller.

    If all appears to be ok, disconnect the panel from the controller and measure the voltage open circuit.
    Instructions are in the following (Voc):

    This should be performed on each panel individually
  8. Here's a photo, I'm pretty sure I'm using voltmeter correct.

    I did not see the video but the voltage looks to be about 35VDC, which means the two panels are wired in series, is this correct?
    If so and your battery is 12V why would you wire the panels in series?
  10. They not in a series, not yet. Two negatives are plugged into that device to mate them into one, as is the positive wires.
  11. As for the video, I guess it failed to load.

    If using PWM the panels must be wired to give closest voltage to the battery.
    That way you will get the most from the panels.
    Just the opposite from Mppt.
    They must 1.5 - 2 times battery voltage.
    If the open voltage is good might be open or missing diodes in the connector box.
    VOC should be 18 volts DC.
    Panels have to be hooked up after the controller is connected to the battery.
    Other wise start looking at the controller.

    Hows things going.
  15. From that Picture his battery was under 9 volts. If that is the case that is why it is not charging.

    The controller requires the battery to be greater than 9VDC to operate
