Q: What battery and solar panel is recommended, MM372W Gate, Houston Texas area. And winter with less sun light?

6 months ago
1 Answer
  • MightyMuleSupport
    A: No Easy Project, the MM372W uses item 3602762 a FM150 Battery, 12volt 7 amp hour available at TSC. The Mighty Mule FM123 solar panel item 3609879available in store and online from TSC.com should work in Texas, but you can upgrade to item 2541061na FM125 30-watt available on line from TSC.com. Moreover, If you want an all inclusive kit, please order the RSCK572W item 1481834 as that kit includes the battery & FM123 solar panel!

Once I installed the batteries the gate started working great. It increased the range of the clickers and is now easier to open and close.

Does what it says it'll do.

My gate was acting up, we have two of these plus a solar panel. I measured the voltage and it still said 12 volts or so, but the batteries say right on them they're only goid for so long. Ordered two new ones online, plugged them in and we were back in business!!
