Convert dc to ac without transforming the voltage
1. I have 8 solar panels. 23 - 29 v output. 7,5 max amp, 175 W max output ...
2. I have an electric waterpump with an expansion barrel pumping up ground water ... The pump is installed below the expansion barrel below the ground surface so i cannot see it. But from experience i know it must be between 1000 and 1500 watt.
3. I have a large capacity of reservoirs to collect rainwater for gardening.
4. I only use the waterpump during the summer when we have exceptional drougth to fill up the reservoirs once in a while. Happens maybe 5 times a year. Maximum 10 times and i only need to pump a few hours max to fill all my reservoirs.
5. I do not like noisy generators.
6. So here is my reasoning ...
If i connect the solarpanels in series i have a voltage between 184 (8 × 23) and 232 (8 × 29) volt.
I think on 184 volts the pump will run slower but i do not care because time is not my enemy but much rather my friend.
The max output will not damage my pump.
The problem however is DC output from the solarpanels and the pump ofcourse needs AC. So i guess i only need to convert from dc to ac. No need to transform to another voltage.
I can find all kinds of converters and transformers combined on the internet but non of them who don t change the voltage.
I have two questions ...
1. Your opinion about my reasoning ... does it make sense or do i see it the wrong way ? I barely know something about electricity indeed.
2. If it makes sense i reckon it would not be that hard to make my own converter fit for what i want to do. How could i accomplish this ?
