How big an inverter do I need for a 1500w household appliance

Do I need an inverter size chart?

The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.

How many Watts should a 1500 watt power inverter have?

Some appliances (e.g., refrigerators or power tools) start at 2-3 times the continuous operating power. Look for inverters with a surge rating of at least 3000 watts if you plan to run high-startup load devices. A good 1500 watt power inverter should include built-in safety protections, such as:

What are the different solar inverter sizes?

Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly. During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.

How much power does an inverter need?

For example, if your total running wattage is 2200W and your surge wattage adds another 400W, your total power requirement is 2600W. Inverters typically operate at an efficiency of around 85%-95%. To ensure your inverter can handle your total load, divide your total power consumption by the inverter’s efficiency.
