Hi all, I am trying to work out what suitable parts to send my family in Cuba so they can have electricity during the long blackouts. At the moment, I cannot afford a full solar setup with panels, but I would like to start with sending them a battery with a charger within a budget of ~1200 USD, and perhaps in the future we could upgrade to include solar panels (right now it is also a risk to have permanent solar panels in the roof since they are being stolen a lot in my neighbourhood). To start with, the idea would be to charge the battery in the 2-3 hrs when the electricity is on. The use case would be to run a small chest freezer (~7 cubic feet), a small to medium fridge, the lights of the house (mostly LEDs and CFL bulbs), and occasionally use an electric cooktop (1000W), microwave or air fryer. But the priority would be to run the chest freezer and fridge so the food doesn't spoil. I also would like to have this system permanently wired into the grid of the house, so the battery takes over when the blackout starts. I do not know much about batteries or solar systems, beyond what I have read on the internet over the last few days. With that in mind, this is the setup that I could come up with: 12V 600Ah LiFePO4 Battery built-in 200A BMS 7680Wh 3500W Pure Sine Wave Power Inverter with Transfer Switch, 12V DC to 120V AC Converter, 7000W Peak 80-Amp 12V Lithium Battery Charger Additional 2/0 AWG battery cables of 1FT and 2FT with 3/8" lugs, since the reviews mentioned that the cables that came with the inverter were not very good 400 Amp ANL fuse kit with M10 stud terminals I realize that these might not be the best quality components, but there is no point to getting components with good warranty, since once this is shipped to Cuba, it cannot be shipped back. So it's better to buy the cheapest available that could be more easily replaced. Here are some questions that I have: Are these parts fully compatible with each other? Is there anything else I should include to make assembly there easier? Are there other websites better than Amazon to buy these components? Could this setup be used together with solar panels in the future? How many panels would we need to charge a battery like this one and what are good affordable brands you recommend? Thank you in advance for your help
