So I'm looking at DC submersible well pumps for an off-grid home water supply. For example, this:
https://pumpsupermarket.com/product...72v-1200watts-600-gph-model-3hr1200-180-2-3c/
I'm trying to figure out how to satisfy the controller's 72V desired input from battery when the solar isn't producing. This seems to be the situation with all these solar DC pump systems.
The two options I can think of are either a 72 battery bank or a DC boost converter on a conventional 24V or 48V battery bank. Either option requires hardware which seems to be unusual and difficult to find - high voltage MPPT charger controller for the former, or a large (>1000w) boost converter for the later.
So, is anyone here doing a DC pump system like this, and what did you use for the battery side of it?
