Save on installation time and labor with the Tank Alert solar alarm system. Since no external power is required, it's perfect for remote installations and retrofits. Alarm runs on two rechargeable lithium-ion batteries powered by a 10W solar panel. Without sun, the alarm operates for up to 72 hours (24 hours when in an alarm condition). For best results, install the solar panel where it gets at least four hours of sunlight daily.

System features a battery-power indicator light as well as a charging indicator that lets you know when enough sunlight is present to charge the batteries. It also includes a test/silence switch and reverse polarity hookup protection.

Includes normally open (NO) SignalMaster float switch with 20'L cable for high level alarm operation, integral mounting tabs, two 3.7 VDC lithium-ion rechargeable batteries, and 10W solar panel with mounting bracket and 10 feet 18/2 cable. 2-year warranty on system; 1-year on batteries.
