How big an inverter should I use for 110v DC

To understand what size inverter you need, you need to know a few fundamental values. The first one is the total wattage of the devices you use the inverter to run. Every device, from your laptop to your cellphone charger and fridge, has a power rating in watts; of course, some are higher than others.

Using the Inverter Size Calculator is quick and easy. You'll need three inputs: Total Wattage (W): This is the total power consumption of all the appliances or devices you plan to run through the inverter. Safety Factor: A multiplier to ensure some buffer above your actual power requirement. Typically ranges from 1.1 to 1.5.

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.

The continuous power requirement is actually 2250 but when sizing an inverter, you have to plan for the start up so the inverter can handle it. Third, you need to decide how long you want to run 2250 watts. Let's say you would like to power these items for an eight-hour period.

1. Introduction: Why Inverter Size Matters An inverter converts DC power (from batteries or solar panels) into AC power (for household appliances). Picking the wrong size can lead to:

A rule-of-thumb for sizing your 1500-watt power inverter is to combine the wattage of all the devices you are planning to use at the same time (don't forget basic necessities, like lights) and give yourself 20% headroom.
