power consumption over the charge controller !!!

calculate input/output

avoid leakage current (e.g. use inverter if not needed)

avoid short-circuit (e.g. false connected cables)

Model:Honda EU10i

Sound Level dB(a)52 @ 7m

Output (Watts): Rated: 900 Max:1000

Output Voltage (V)230 (+ 12V)

Operating Hours Without Refuellin:3.6 to 8.3

Fuel Type: Unleaded petrol

Common: Calculating power

Power: P=U*I

example:laptop power supply (19V*4.62A=87.78W=90W)

charger (12V*1.5A=18W)

USB charger (5.1V*0.85A=4.335W)

elec. energy consumption: W=P*tin case of the laptop, e.g. needs 4h to charge the battery

W= 90W*4h = 360Wh
