Might these work for me too? I saw some of them on Amazon ( ) but many reviews complained about a noisy hum and malfunctioning.

I have heard of something called 'contractors' and saw these recommended for a different application. Solar Submersible Water Pumps 12 Volt Brushless Solar 12v Dc Water Pump for Irrigation, find complete details about Solar Submersible Water Pumps 12 Volt. I live in mountainous Costa Rica and this battery-less system will be a great boon to us. These pumps are designed to be submerged in water and use solar energy to power the motor, which drives the pump.

Submersible solar well pumps are an innovative solution that can provide a reliable and cost-effective way to pump water from wells. To prevent pump overheating/failure I need something that will sense power levels and cut off all power to the pump when power is less that the required 12 volts and 6 amps DC. Submersible Solar Well Pumps: Efficient and Cost-Effective Water Solutions.

It is important on a battery-less off grid system that the pump not try to cycle when the sun is not sufficient to run it efficiently. I want to send water up hill to another tank with a toilet type float to shut off the water when the tank gets full. It operates the pump again when the pressure falls below 35 psi. The pump has an internal automatic shut-off when the pressure reaches 55 psi in the 1/2' output plumbing. DC Solar Water Pump Germany Technology Over View MODEL(LSWQB-12) 15m Lift 12V DC Submersible Solar Water Pump, 0.5HP Deep Well Solar Powered Surface Pump. This has to have an automatic shut off when solar is insufficient to run the pump. 12 volt DC submersible pump, 4m3/h maximum and 12m head maximum. But we recommend a solar charge controller because high and unregulated voltage spikes may cause damage to the pump.I need to make a water tank (1100 litres) with solar panels on top, and a solar powered Shurflo 12 volt water pump mounted on the bottom to send water uphill to home or livestock watering trough. Q: Can it be connected directly to the solar panels?Ī: Yes, you can directly connect this pump to a 12v solar panel. Solar West pumps do not have a check valve, to facilitate efficient water drain back, allowing you to use the pump earlier. While water is a scarce commodity in much of Australia, sunlight is almost constantly in abundance, particularly in the Australian Outback. The pump can be used with an Aquarium or any other small solar-based pumping application. Q : How much watt solar panels are required to run this pump?Ī: 100Watt 12V x 2 pieces in parallel connection Solar West floating pumps have a maximum lifting capacity of 40 and can be powered with as little as 1 - 64 watt panel and a single 12 Volt battery.These pumps are ideal for pumping from dugouts, lakes, rivers and streams. We would only ever suggest a DC pump (12 Volt or 24 Volt) for households that use very little water. This Solar DC Mini Submersible Water Pump Motor 12V. This DC 12 V Mini Micro Submersible Water Pump is a low cost, small size Submersible Pump Motor which can be operated from a 12V power supply.
