If you intend to use a microwave oven with a battery system, please be sure to read this article. Microwave ovens have two specifications: microwave output power (W) and power consumption (W). Although both use the same unit (W), when checking whether a microwave oven can be used in a backup battery system, it is crucial to confirm the power consumption, not the microwave output power. Please be careful not to confuse the two.
Even if the output power is set to 500W, the actual power consumption is not necessarily 500W. If the power consumption is mistakenly thought to be 500W and connected to an inverter with an output power of 1200W, the output overload will trigger the protection circuit and the inverter will stop running. In the worst case, the inverter may fail and the power supply will not start. Power consumption is usually marked on the back of the microwave or documented in the owner's manual, so be sure to confirm the value.
Basically in the United States, it is rare to find a microwave oven that consumes less than 1200W. In addition, even if the power consumption is marked as 1100W, do not blindly believe it, because the starting current of many high-power appliances, such as microwave ovens, air conditioners, etc., may far exceed the power consumption during use.
If the starting current exceeds 1200W, it is obviously not enough to use a 1200W inverter (it is recommended to use an inverter with a power of more than 3000W). In the worst case, the inverter may be damaged. Because some manufacturers of home appliances do not record starting current in their user manuals, be sure to confirm this information with the manufacturer before using high-power appliances such as microwaves or air conditioners.
If the inverter is damaged due to output overload, the inverter manufacturer's warranty may not apply, so please be aware of this.
