I installed the pump using direct-connect to a 100 watt solar panel. It ran flawlessly when the sun was shining, for 3 months, then just stopped. I found that the housing was full of water. I contacted the Amazon seller who in turn contacted the manufacturer. I received several emails from the manufacturer over the next month. Most of which, after the first one, were prompted by my follow-up emails to them. I received a replacement in about 1 month with no requirement to pay anything or to return the failed pump. I was happy. Fast forward 30 days, the replacement pump has stopped working. Voltage is good from the panel and there's no water in the housing this time. It simply stopped. I'm going to contact the manufacturer again but I do not recommend this pump, perod.UPDATE: The seller, Fister-US, contacted me. That alone is amazing. They not only provided me with a 3rd pump (2nd replacement), they provided a refund for the trouble. I will return to this review and change it to 5 stars if this new pump last several months. I'm inclined to believe it will if water doesn't leak into tbe housing. I believe the 2nd pump may have died prematurely due to low voltage. The spec sheet that comes with the pump doesn't provide rated operating voltage range. The saller provided me with 20-36 vdc as the range for this 24 volt pump. I foynd reference to tbe pump operating on 12-24 vdc on forums and other reviews. With that being inaccurate, I'm hoping the increased voltage will provide for a longer life of the pump. I'll update this again later.

I bought this pump to provide water from my well to my vegetables. Unfortunately, its diameter was too big to slip past the side-saddle in my well casing. I tested this pump with a 12 volt, 100W Renogy Solar panel and it pumped beautifully. Perhaps I can find a different use for this pump.

Dura poco con la extraccion al 100 % ( 15 minutos ), disminuye su presion de extraccion, posible se acabe el agua del pozo y su recuperacioin sea mas lenta que la rapidez de la bomba. Estoy monitoreando.a los 10 dias fallo totalmente, la saque y salio sin la carcasa despues del anillo de absorciion..Solicito su intervencion para su reposicion tiene seguro.

I ha e a problem with this pump will run for few mins very strong pump. However 3 to 4 mins of run time in water that is 50 to 52 degrees Fahrenheit pump shuts off for no apparent reason. I have contacted ted the seller about this problem they were worthless as far as help. I beleive that the thermal switch is faulty or wrong one installed. Seller didnt offer to exchange pump. All they want was pi true of the battery. I can tell u the battery is new with 20 amp solar charger and 350 watt solar panel . Panel can provide 12 to 15 amps of power to the battery. Voltage when pump is running never drops below 12.2 volts . I will be disassembling the pump myself. I will update when I find the problem.Update after disassembling the pump found thermal switch. Must have been sumthg wrong with thermal switch or wrong one put in. The way I found this was I put thermal switch under hair dryer. And thermal switch goes open at 90 farenheit. With no documentation I could fi d what the thermal switch was supposed to be rated for. Took wild guess and got thermal switch for it rated for 300 Fahrenheit. Pump work great.

La bomba solar funciona muy bien, me está subiendo el agua alrededor de 60 metros , con poco caudal claro. Pero es un flujo continuo durante todas las horas solares. En 8/10 días me llena la balsa de unos 25000 litros. El único defecto por corregir algo es la salida del agua de la bomba que es a presión, debería de ser de rosca. En mi caso que tiene que subir el agua a mucha altura 60 mts a veces se sale la manguera del cuerpo de la bomba, pero en cuanto a funcionamiento todo muy bien

This motor is not worth the installation hassle. The first pump was used for 1 season then pulling it back out of the well in the middle of August. This first assembly lasted 1 year and 2 weeks with about 6 months of heavy, every day, summertime usage for the garden. After I learned about the expired warranty position of the manufacture, I disassembled it to find clues for why it failed. The first unit had signs of uneven commutator wear. This uneven wear indicates one side of the commutator winding group was heavily eroded possibly from excessive current, foreign object debris, or misaligned brush contact. I’m not leaning towards bearing misalignment since the clearance tolerance is tight for permanent magnet DC motors. I have not measured the coil resistance on the rotor assembly to determine if coil windings have overheating. I may do that inspection of the circuit resistance if provoked further.The manual has replacement part numbers however nothing on the web site which is a good thing. It prevents you from putting more of your earned money and time into this defective design.After the “unofficial” failure analysis (not through a certified testing facility but more of 20 years engineering experience), I purchased a replacement for this failed pump and it immediately started overload cycling after 2 weeks. That one would cycle with only 50' of head pressure (21.7psi). I tried to replace the original with the exact same model (benefit of the doubt) so now I have experienced 2 failures with the same model number. These canister type pump/motors are designed to fail once the O-ring gasket fails to keep the water out. You get what you pay for with this model. Not recommended for use. Save your money for a better assembly.
