Minimum two SP120 solar panels needed. Just buy the five panels.
After the cold spell and no electricity for a many days in Texas, bought the Bluetti 2000wh (AC200P), with five (SP120) 120watts panels, based on reviews by Hobotech and Will Prowse on YouTube.
Takes me ten minutes to deploy all five panel on the deck. On a clear day in Central Oregon, charged the batteries from 32% to 100% in about 3-1/2 hrs, between 12pm and about 3:30 or 4.
Test so far making breakfast:
Kettle boil wataer, toaster, induction cooker for eggs;
day one used up 15% of 2Kwh, day two 10%, did it faster 😁. Sofar I figure that I can charge the battery every 5 days.
No, you can't use the Kettle, Toaster, and Induction cooker at the same time. It's done serially! One at a time!
I learn that the Inverter (DC to 120vAC) uses up 2% per hour of the 2000wh battery just sitting there ready for use.
Lesson: turn the Inverter On for use then turn it Off. Think about this way; your phone uses battery just sitting there not being used. When it is Off, it is still using battery, talking to the towers.
Have a refrigerator in the garage, Amana (TX21A3L, 115VAC - 7.74amps) and using a kw-meter for 12 hrs real time, it run for 7:16 hrs and used up 1324 wh.
Have not run the refrigerator with the Bluetti yet. So. From the numbers I can derive that the battery needs to be recharged every day. And yes, you can use the Bluetti while charging the battery with the solar panels.
