Battery and Solar

Notes
All lights on the WIC2 box should be solid green (or flashing green in test mode)
Use this guide to diagnose flashing and error lights that appear on the WIC2 computer box for Battery and Solar.

No action is required for solid green lights, therefore, they will be ignored for the purpose of this troubleshooting guide.

Battery and Solar

Idea
You will want to diagnose a problem only when the Battery or Solar lights are NOT solid green

Tools Required

  1. Smartphone with up-to-date Optiweigh app installed
  2. Multimeter
  3. Philips head screwdriver
  4. 10mm spanner
  5. 16mm spanner
  6. Standard 20A Blade fuse
Info

The Battery light will change colour based on the voltage at the time

Green = Above 12V

Red = 12V or less

The Solar light will change based on the last time it charged

Green = Charging in progress OR >14V
Red = Over 24 hours since last charge

Diagnosis

Check the Battery and Solar Voltage at the Unit

Using the Optiweigh App:

  1. Connect to the unit WiFi, and turn off mobile data
  2. Open Optiweigh app -> Unit Maintenance -> Check Unit
  3. Check the Battery and Solar Voltage. Solar should be the same as or higher than the Battery
  4. Take a screenshot to refer back to if you talk to the support team

Idea
If you can’t connect to the unit easily, take a Phillips head screwdriver and unscrew the blue WIC box from the backboard, then try again.

Using a Multimeter

  1. Test the battery with the power plugged in
  2. Unplug the power and test the battery again
  3. The voltage should be higher with the plug in if the solar is charging

Resolutions

1 - Check the Fuse

The fuse can be found in the black holder, usually above or behind the battery

  1. Turn the WIC box off and remove the power plug
  2. Open the fuse holder and check the fuse.
    1. If blown, replace with a standard 20A blade fuse
  3. Ensure the connections on the battery are tight

2 - Charge the Battery*

Charge the battery to temporarily keep the unit going

  1. Unbolt the battery with a 16mm spanner and take it to a charger 
    1. Ensure no bolts / washers are lost
  2. Once charged, replace the battery and connections
* This is a temporary measure, only to be done as a last resort. Get in touch with Optiweigh Support at (or before) this stage
Warning
Never tow the unit with the battery loose in the top box!
