Pump 500W DC 48V Solar Water Pumps, Max head 393ft,7.9GPM Flow，3 inch Solar deep well submersible Pumps with MPPT controller float switch kits for home or farm

This pump works so well!!! It was easy to install and pumps about 8 or 9 gallons per minute from a 30 foot deep well using 2 48v 400w panels in series.... The controller changes the pump rpm depending on the occasional cloud blocking some of the light... It is completely automatic and does not need you to be there at all.... I am so happy after trying 2 cheap solar pumps from Vevor which burned up within 2 hours....

I have to say I was skeptical at first of buying this and even more skeptical when I received it because of how small and lightweight the pump was. I figured there was no way this little pump is gonna produce any legitimate amount of water out of a 130ft well. I was wrong but more on that later. Setup: For me the setup was fairly easy, I know the well will produce more than I can pump and I am pumping into a 1 acre pond rather than a tank so I did not bother with any of the level switches that turn the pump on and off based on well or tank level. It was just splice the wires together (I used a well splice kit from Menards), hook up the drop pipe (I used 1” poly pipe for potable water usage), connect a safety rope and drop it in the well casing and hooked it up to the solar panels. The only hiccup I had here which maybe the manufacturer can correct is that the tags on the pump cable (w, v, u) were not correct and made the pump spin backwards which results in the impeller unthreading and popping out. We switched one set of the wires at the controller and pushed the impeller back in and then when the pump started it re threads the impeller back in as it is spinning the correct way. I would recommend putting the pump in a 5 gallon bucket and starting it up briefly to ensure it is spinning correctly and pumping water. This would have saved us from having to pull the pump back out of the well after the initial startup attempt. Regardless it didn’t damage anything or cause too much grief so I am not docking it any stars for that. Performance: 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. The water level in my well is right at 130ft below ground and this pump is able to fill a 5 gallon bucket in under 1 minute (5.85 gpm). The controller also has worked well for my application as it shuts off when the sun isn’t shiny and runs on and pumps when it is shining. I am using 8 x 100w solar panels and still only get max rpms for about 4 hours a day. So if you think you can get by with 500w of power you will likely be disappointed. From what I can tell the controller tries to maintain ~70-75 volts by adjusting the pumps rpm’s up to 4000rpm. There really isn’t great instructions on any adjustments or settings changes on the controller to adjust really anything. I tried to press the “settings” button and it just give like a p-0 message that you can adjust but I have no clue what I am adjusting so I just least it alone. It has performed well out of the box with the default settings. Overall, it has been good so far for the money. The well company wanted to charge me 7500 for a solar pump setup so for the tots cost of this system I have saved a lot of money and still get good performance out of it.

Had a problem with the pump that was originally sent, but they took care it and sent me a new one. Troubleshooting was a difficult process but the pump works.

This company is excellent and their customer went beyond to make sure they resolved my issue with my pump. They replaced the pump. I recommend this company and their product which requires only two solar panels.

We installed this 500W DC 48V Solar Water Pump a month ago, and it has been working flawlessly. The pump delivers great pressure, and on sunny days, it provides plenty of water. If you're in an area with frequent cloudy days, consider adding batteries for continuous performance. The installation was straightforward, and everything worked as expected. We’re so satisfied with it that we’re buying another one as a backup since we live in a remote area. We’re also looking forward to upgrading to the new MPPT controller with WiFi once it becomes available. A huge plus has been the amazing customer service! Every time we’ve had a question, they’ve responded quickly and helpfully. Cathy has been especially great—super responsive and knowledgeable. It’s reassuring to know that support is always available when needed. Highly recommended to anyone needing a powerful, efficient, and reliable deep well pump, backed by excellent customer support. We will definitely recommend it to our neighbors!

Pump works great. Customer service is great. Here is my setup. Pump: 1830 ft of ¾ pex pipe that pumps into a storage tank. About 180ft ft or more total elevation. We are pumping from a sistern. Power 3s2p 100w solar panels 4x 12v deep cycle batteries. (48 volt system) 1 charge controller I needed a solar powered pump, that was high head. We tested the pump on the solar panels in the summertime and it ran with no issues. When we got the pump installed during the winter months, we had alot of prep work to do. The solar panels did not get enough sun, due to tree shade and clouds. That is when I hooked up the batteries. I contacted customers services, on what was the best way to wire everything up. They responded quickly what the best practice for wiring it up. When I ran the pump, to check it would pump I measured a little over 1 gpm, the pump was running around 2800 rpm. While I was finishing up the installation and getting everything set in place, we had alot of rain, come in and soaked the panel. I contacted customer service once again for support on getting a replacement. Once again they replied quickly and are helping me get the part I need. I was impressed with how quickly they responded and helping me get my pump running again. I am truly impressed with this pump and customer service. If someone was asking me what they needed I would look to see if this pump would work for them. *I did hook up a golf cart charger to top off the batteries at night in case the panels could not.*

Background: Been ranching in S TX for 40 years and have been using solar pumps for 30. Been trying to use this pump almost 3 months in the brightest and longest sun light days, summer time. The reliability and functionality of this pump is poor at best. The well is 350 ft deep with 100 feet of water. Location gets over 300 days per year of intense sun. The pump that this one replaced was a Grundfos SQFlex, was looking for a less expensive alternative. The pump is placed at 300 ft. which gives it a 250ft head. The voltage supplied by the solar panels is 72 volts. If another panel is added that brings the total voltage to 108 volts the controller shuts the complete operation down due to hi voltage (8 volts). At that depth under optimum conditions with 72 volts the pump will only pump 1 maybe 2 gallons per minute water flow rate. Customer service has been helpful but unable to get the pump to work anywhere close to the advertised specks. As far as the durability on the product it seems good but it does not function as advertised. This pump might work better in a much shallower well but it does not operate any where close as advertised. Definitely not good for a commercial or an application that relies on reliability.

Unit is set at 320 feet below surface. Had to increase voltage at the control unit so i would have 48 volts by the time it ran through 360 feet of wire. Now working fine.
