Viper Power Pack 25

Power Pack Instructions:

• Plug the solar panel in any of the ports, if you have 2 solar panels you can plug both at the same time.
• The optimum tilt angle is calculated by adding 15 de-grees to your latitude during winter and subtracting 15 degrees from your latitude during summer. For instance, if your latitude is 34°, the optimum tilt angle for your solar panels during winter will be 34 + 15 = 49°. The summer optimum tilt angle on the other hand will be 34 —15 = 19°.
• Best to charge the VPP all day in the direct sun, 6 to 7 hours mini- mum.
• Light bulbs included 3 Watt each, and switch with 4 stages.
• Cold weather will affect the performance of the batteries inside the power pack. The subfreezing temperature will lower the charge capacity and ability to hold the charge for long time.
• When the battery is depleted connected devices will disconnect auto- magically.
