Don't think about it. After a while, the battery will be dead, 1000W, 12, which requires a current of 83.3A It is reasonable to say that 100A battery can be used for more than an hour, and the actual battery has a virtual 1 standard, plus the inverter conversion power consumption line loss,1. At least 2000W should be sold for two or three hundred kinds of step waves, and sine wave 1500W is enough, but the sine wave with high price 1000W is more expensive than the step wave of 2000 W. However, it is often recommended to buy sine wave, which is suitable for all kinds of electrical appliances. The step wave can only be used with resistive loads, and some electrical appliances cannot be used.
