- Using the Solinst-supplied Solar/12 Volt Cable Assembly (pt# 109452), shown in Figure 6-5, to connect to a user-supplied external 12V lead-acid battery (minimum 60 Amp-hour). See connection diagram in Figure 6-6.
Note:
The external 12V battery should have a minimum 60 Amp-hour rating. It is recommended you have a higher Amp-hour rating if you have a high report rate, or if your station is in a very remote location and you are not able to replace the battery easily.

- Using the Solar/12 Volt Cable Assembly (pt# 109452) to connect to a user-supplied Solar Panel (minimum 15 watt) with a built-in regulator for 12V. See Figure 6-7 for the connection diagrams.
Note:
Solar panel power will not be available at night or during very cloudy conditions. If Reporting sessions are scheduled for these times, the internal batteries will be used.

6.1.2 Solar Panels
A solar panel is connected to a RRL station using the Solar/12 Volt Cable Assembly (see Figure 6-7). The solar panel is user-supplied. The panel should output a minimum of 13V open circuit in order to effectively re-charge the batteries. As a guideline, the solar panel should be at least 15 Watts. Higher wattage panels are also suitable. The solar panel must also include a regulator to handle external battery charging cycle.
