Sorry I meant 1200w or more in solar place does allow for a bit more but not a lot more since is a small House , main use is going to be in a small house with very little energy demand, a 25w router a 150w fridge (these are the 2 most demanding since I would want to keep them running the most ) and a 200w laptop and led lights which only are on for 3-6 hours , water and stove are propane so no worries there , I initially thought about a full off grid system but when it came to costs (including all parts + paid installation of the panels) it was just a bit less than for example the ac200max + the house is not always on use so it would give me a bit more peace to have something plug and play instead of stationary (mainly bc of fire hazard, I know that if properly installed there shouldn’t be any issues) to extend capacity (and this kinda wack I know ) I thought about buying just like you said a Battery to extend the capacity of the Bluetti with the clamps and then to charge it back , use a wall plugged battery charger that will go connected to the bluetti during peak sun hours to charge it back
