Tips: 3 important points for solar water pump installation

  1. The DC controller must match with the recommended solar water pump. Don't use the controller for other pumps.
  2. For the perfect performance and long-life working, the controller should be kept away from strike, shake, sunshine, salt mist, oil mist and etc.
  3. Because of the power loss of cable, try to use the shortest cable when installing a solar water pump. While using longer cable, don't use single-wire to connect solar water pump and DC controller. For example, while the cable length between controller and 12V solar water pump is shorter than 30m, the cable size should be at least 2mm2. While over 30m, the cable size should be at least 4mm2.

Easy to setup and better than expected performance
High quality 80w solar water pump, ship packing as good as it gets. This little pump has exceeded my expectations. The pump curve they supplied seems to be accurate and maybe even a bit conservative in how much flow you should expect.

It looks like a nice little pump!
This set looks great! It's easy to connect. The pump is rubber lined and has a stainless steel impeller shaft running through it. The whole system looks fine, my only concern is how long it will last. Time will prove everything.

Great 80W solar water pump with great power
Great 12V DC solar water pump and has strong power. I purchased the 80W solar water pump about three years ago. Pump work flawless as long as there is enough sunlight.
