Hi first time poster so please let me know if there are any threads i should look into if some of what i am asking has already been covered. Since this is my first post I will provide some background, but it anyone wants to skip to my question it will be further down in the "My question" heading.
Background
I have a farm that started moving to solar 6 years ago. We installed a 16 x 275w panel array and inverter (not sure on brand) to run a 2.2kw submersible pump to pump water from our borehole into a 150 000l reservoir for our livestock. It has worked flawlessly. During winter, the pump is run once every 2-3 days for 3-4 to replenish the reservoir and in summer is in run daily for around the same duration. It is located approximately 300m from the farmhouse.
We also have a small solar setup in our farmhouse which consists of 1 x 300w panel, 1x pvm charge controller and 1 x 24v 100ah gel battery. This was installed when the house was built around 5 years ago and our initally requirement was just to have led lights in the evening and charging capacity for our cellular devices. We spend approximately 50 days a year on the farm and therefore didn't have much there initially. We have since added more and more devices, primarily tv and satellite dish, more lights and security cameras. They all draw around 150w in total when running.
We live in a semi arid desert in Botswana, Southern Africa and we probably have around 300 days of full sunshine per year. In our hours of sunshine average 10.5 hours and in summer around 13 hours.
My Question
We want to upgrade and integrate the two systems mentioned above. I would like to upgrade the house to a 5000w growatt invertor and 5.12kw lithium battery. I wanted to know if we can use the existing 16 panel array to power both the house and the pump? I assume I would have to place the invertor and battery near the existing solar panels and run a cable from the invertors to the farmhouse(300m). The initial installer only deals with solar pumps for boreholes and has said it is not possible to integrate his setup to an hybrid invertor that can be used to power the house. However since the pump only uses the panels for at most 20% of the day, i don't know why can't use the access power generated to power the house and charge the batteries..
I am a computer engineer by profession so know basic electronics and not much about solar installation and since the farm is extremely remote (7 hours away from my primary residence) I wanted to know if there is any information i need to collect when i am there to know if what i want to do is feasible or if i should just purchase additional panels and setup a discrete solar system for the house.
