Solar Well Pump Linear Current Booster Photos Ron Castle's Simple Pump

We drilled our water well at www.nealcreekfarm.com in Franklin County, Tennessee in April 2011 and installed our Simple Pump as a hand pump initially.  The installation took two of us an hour and twenty minutes to put the pump at 91.5 feet in a 100 foot well.

Simple Pump Initially Installed As A Hand Pump

The motorized head to operate the pump as a solar well pump was added in May 2011 so that the block layers working on our new off grid house construction could make mortar.

The pump house is now completed and the installation of the solar pump powered by a 210 watt Evergreen 12 volt solar panel and a linear current booster is finished.

The pump house is 8 x 12 feet with a 10 foot roof on the high side for future maintenance of the Simple Pump cylinder which is attached to 10 sections of 9 foot Schedule 120 PVC pipe.

The 210 watt panel is mounted to the block wall on T-hinges using Tapcon concrete anchors.  This allows an easy panel angle change from 20 degrees in the summer to 50 degrees in the winter.  To the left is a Midnite Solar combiner box with a 20 amp breaker and Delta lightning arrestor.

The conduit through the wall brings the current from the combiner box to a 4 connection terminal strip. The positive is connected to the red linear current booster wire, negative is connected to black.  From the linear current booster the white wire is connected to the pump positive and blue to negative.  The Simple Pump has a built in switch with fuse so no further overcurrent protection is required.  Some folks might want to also use a DC rated breaker.  The breaker rating depend on the solar panel being connected.  The lower pipe on the wall goes to fill the storage tank. The upper pipe is being stored for the addition of a outside frost-proof faucet.

I added a second terminal strip and a 30 amp relay to handle the amp requirements of the Simple Pump motor so that I could use an 8 amp mercury free float switch to turn the pump on and off according to the water level in the tank.  See our low voltage relay wiring for off grid solar page for a video and instructions on how to wire a relay.

In October 2012 we changed out the Simple Pump Scotch yoke drive for the new linear bearing link drive, rewired the pump controls to use a signal wire from the linear current booster rather than an external relay, added a float switch bypass switch so the pump can be operated when the storage tank is full, and added LED lighting to the pump house.  Please watch the video to see all the changes and how the system works.

Pardon the tools on top of the tank.  This is a 550 gallon storage tank which will gravity feed water to the house and to Sunshine Cottage.  The water will be boosted in each dwelling by a small pressure pump.

Gentlemen take note: A platform will be built over the tank because sleeping in the pump house will be warmer than sleeping in the dog house during the winter.

No, we don't have a leak.  The drain line to the right was used to fill a water bottle.  The far line goes out through the floor to a tee which splits one to the house and one to the cottage and both of those lines have their own shut off valve.  If you note the water level in the tank, Simple Pump pumped about 450 gallons on September 28 from when the sun first created enough amps to start the pump motor until 12:20 PM.  I was not there when the pump  started.  My guess is about 9:30 AM.

Now that we are fully operational I will be recording some information that will be useful regarding specific performance under specific conditions.  This will help us to make better recommendations regarding linear current booster pumping versus batteries when water volume per day is critical.

In May 2014 we added a second pump to the well, a SHURflo 9300 submersible pump which operates from a 24 volt battery bank.  The panel on the left is a 120 watt 72 cell 24 volt panel a SolarLand SLP120-24U.  The submersible is a backup to the Simple Pump and is mainly used for irrigating the raised garden beds that are down the hill from where this photo is taken.
