First, Your website and videos are fantastic, very good information…thanks.
I am having trouble understanding how the manufacturers are calculating the hours that certain appliances can run on their solar battery “generators”.
Bluetti AC200 – 1700Whr battery – max inverter output = 2000watts
They claim:
Refrigerator(300 watt) – run for 17 – 19 hours
Toaster (900 watts) -run for 1.6 – 3.2 hours
Fan (25 watts) – run for 36 hours

I thought:
- amps X voltage = watts
- battery capacity given in watt/hrs – meaning that a 1700 watt/hr battery could produce 1700 watts for one hour and then it was empty. Or 17 watt for 100 hours.
- Amp rating for appliance x voltage of appliance = watts (continuous need to run appliance)
- So for example the refrigerator referenced by Bluetti (AC200) uses 300 watts continuously.
- 1700watt hrs divided by 300 watts = 5.6 hours. What are they talking about 17 -19hours????
