Hi all,
I am assembling a solar system and I would needs some help accessing if what I want to di is viable or if I will ending up burning down the house or frying some components.
First I would rate my overall knowledge from 1 to 10 as a solid 3 (maybe 4 if I take my vitamins) so I probably know just enough to not hurt myself but probably ruin some expensive equipment if not guided.
The objective:
This is meant as a backup for now, meant to power lights (not the entire house), a fridge, a chest freezer an oven and some other odd appliances (think toaster, coffee machine, charge cell phones, etc.). But I want to be able to upgrade and add more off-grid capability.
If I go by my power bill I consume on average 17kWh per day, but this comes with a caveat, much of that power is used for heating water, pure waste and appliances that are constantly on just consuming and that will be left out of the system entirely, and 2 pumps (I have a well, that I *think* is 100 ft, roughly 30 meters, deep that fills a ground level cistern from where another pump draws water to serve the house and garden, keep in mind the last pump turns on every time the pressure gets lower than 1.5 bar, so quite often), those pumps are power hogs and I will address them in the future, but for now they are tied to a diesel generator. I think that if I cut enough "fat" I can lower it to 10 kWh.
So onto the system itself:
I am thinking of using a Growatt SPF 5000 ES powered by 6 or 7 500w panels in series and use 2 pylontech US 3000C 48v batteries in paralel as a power bank.
The panel's specs will be provided below as the batteries and the MPPT/Inverter are very common and a known variable
Should the battery cable that connects to the growatt be 2 or 4 gauge?
I am not connecting this to the grid, so I am thinking about connecting the growatt to it's own panel where the appliances will be connected to, through a power outlet. So should the breakers be of what amperage, (20, 15, 40?), and how thick should the gauge of the wire be? I am thinking 12 but that is just a guess.
I am in southern Europe, so I get a lot of sun (annoyingly so), and the power being 230v 50hz that would mean I won't need any transformers right? In theory I could just plug an appliance into the growatt and expect it to power up, correct?
For now this is all I can think of, sorry for the infodump but this is so you have as much info as possible, so you know as much as possible and are not frustrated.
Below, you will find a diagram of what I intend to do and specs for the solar panels.
Thank you in advance for your help
