Why is my Vantage Connect or EnviroMonitor battery low?

There could be a number of reasons, including:

  • Obscured or lack of direct sunlight on the solar panel
  • Prolonged temperatures of -4 degrees F (-20 degrees C) and below
  • Possible physical malfunction

When fully charged, the battery should last for approximately 21 days (without recharging).

TROUBLESHOOTING ACTIONS

Obscured or lack of direct sunlight:

It's possible that your Vantage Connect or Gateway solar panel could be covered with snow, vegetation or dirt so make sure your solar panel is unobstructed to receive maximum sunlight. If your Vantage Connect or Gateway is in an area where the solar panel is not exposed to sunlight for the majority of the day (due to prolonged cloud cover or shadows), you should either move or turn your solar panel so that it receives adequate solar charging. 

Cold Weather:

When temperatures are -4 degrees F (-20 degrees C) and below for prolonged periods of time, the battery is unable to recharge itself. Once the weather warms, charging via solar power will resume.

If you routinely experience temperatures below -4 degrees F (-20 degrees C), consider moving your Vantage Connect or Gateway indoors and supplying electrical power directly to the unit (if power is accessible) using Davis' Optional AC Charger Kit. This optional charger kit supplies power to and charges the battery using a specialized adapter, AC plug and power outlet. You can find the charger kit here. 

Check for Malfunction:

If none of the above conditions apply, please check your installation to make sure all cables (i.e. solar panel cable, battery cable and primary power cable) are connected properly. Please refer to your Vantage Connect Manual or Gateway Instruction Manual for details on where to find each cable.

If possible, measure your battery's voltage with a volt meter. A well-charged battery will measure above 6 volts.
