Hi All.
The project, we have a large pond on our property, we use it mainly for watering the garden, and we rear some fish, vie an electric pump this time of year with usage and evaporation the level drops quickly.
At the back of land is a small river distance about 220 meters, the idea is to use a sola pump to pump the water from the river to our pond.
By using a trailer mounted unit, similar to the photo, but a lot smaller, say going out in the morning and coming home in the evening.
I aim to use a 2HP pump, with a 2-inch outlet, looking at Google it will need 1600 Wats to power the pump, our local Thai Wat Sado has all the stuff they have 400-Watt panels, inverters, and pumps.
The questions are, using a DC pump, you should not need an inverter?? Wat Sado has one a 2HP DC pump 13 000 baht, as far as I can see you should not need a battery, but the guy in Wat Sado said you do, do you?
As I said our pump we use in the garden, I brought 10years ago ,it is a Mr. Eco ,Italian made pump ,one of the best you can get ,we had it 18 months brought it out at the new year ,would not start ,took it to our local electric motor guy ,who had to rewind the motor, I said it is an Italian pump, he said no, a Chines copy ,it had aluminum windings ,not copper ,he rewound it with copper ,now no problems.
The 2HP DC pump I was looking at was made in China, thinking will it last?13k for a 2HP DC pump, so I thought buy a good quality AC pump and use an inverter?
Google said you need 1600 Watt to power the pump, but I have read on start up an electric motor needs more power, just to turn the motor over, once it is going then it will use its 1600 Watt's, if so. would you need say an extra panel, for start-up.
Thanks.
