I have started planning my second build and want to confirm my plans before I order parts.
The first project was an off grid solar setup to power an electric fence for farm pasture.
For my next project, I would like to get it up and running without a battery.
For a quick install & setup,I am thinking I can go direct from a panel to charge controller to inverter tointermittent on/off timer to pump (4 amp).
System Power to pump would be off at duskuntil I build a battery. (Yes would still need a small battery as required by charge controller)
At dawn when panel reaches required voltage, the pump would start cycling again (Power cycling recommended to prevent heat buildup in pump).
Question: I want to reuse the same/similar setup I used on my fence which was 100W with 30 amp charge controller.
Since I did not need to deal with any inverter sizing& conversion lossesfor my first setup, what would be a typical spec for an invertertodirect power the (4 amp 120v pump)?

Seems like there are a lot of junk inverters out there that I need to sort through.

RE: Modified sine wave not good for "any" electric motor. When it comes to electric motors, the ratings on the tag are "running" values, not starting values. Generally speaking, an electric motor can consume up to 5x the rated power when starting up. A compressor style motor will most likely get closer to that than one like for a fan.
