A 4000 watt inverter is enough to run most 1.5 HP AC well pumps. These pumps consume 1500 watts but the surge wattage is double that, which is why a 4000 watt inverter is the best choice. .
An AC well pump requires a lot of power to start up and run. It is comparable to running an air condition on solar, so make sure your inverter can handle its requirements before. .
A 4000W inverter can run a 1.5 AC well pump for 2 to 3 hours. The runtime assumes the pump runs for 20 minutes an hour and is rated 1 to. .
Majority of AC well pumps used in homes are 1 to 1.5 HP, so that is what we will use here. If you have a 1.5 HP pump, its running watts is. .
AC well pumps are more affordable than DC pumps and easier to maintain. DC pumps are more efficient, but for home use, an AC system. It has a power output of 1,500 watts and an input voltage range of 200 to 450 volts. The total solar panel power would need to be at least 2,925 watts, or 1.95 times the pump power. This means that you would need at least six solar panels in series.
