Best 1000 Watt Inverter FAQ

What to look for in the best 1000 watt power inverters?

To decide preferable features in a 1000W inverter or that of any other rating, application must be kept in mind. E.g. if it is to be used for a car, its compactness and light weight will be a plus. Solid structure with durable material (that doesn’t undergo wear and tear in humid environment) should also be a factor to consider. Type of output waveform (pure sine wave, modified sine wave, or square wave) must also be paid heed to. Providing best available features at lowest cost is also desirable. Voltage tolerance limit at input and output level must also be reviewed according to available battery and prospective load respectively.

How to pick the right 1000 watt inverter for going off grid?

While going off-grid, peak or surge power rating of inverter is an important factor to consider. It should be considerably high if compressor or motor based machinery is to be attached with inverter. Advanced protection system (overload, underload, short circuit protection etc.), ample protection tools (fans, fuses), good usability (availability of remote, LCD displays, alarms, LED indicators, connections, replacement of fuses etc.), and cooling system should also be deciding factors. To run maximum categories of appliances, pure sine wave inverter is preferable. If cost is deciding factor, then modified sine wave inverter can also be chosen.

What will a 1000 watt inverter run?

A 1000W inverter has almost 800W power available to run appliances assuming its efficiency is 80%. So it can run any type of load(s) which need(s) less than 800W in total. This load can include chargers, computers, microwave etc. If load includes motor or compressor, then it is advised to keep continuous load less than 200W because their surge power is too high.

How long will a 12v battery last with a 1000 watt inverter?

It depends on size of battery (Ah), discharging capacity of battery (dependent upon its type), and connected load. Let’s suppose that we have a 12V, 80Ah battery which is fully charged at the moment and can be discharged up to 50% of its capacity. It means we have 40Ah available. Account for battery losses and consider battery output voltage would be 10V. if total AC load connected to inverter output terminals is 1000W at the moment, then inverter can run on battery for (104060)/1000= 24 minutes.

How many amps does a 1000 watt inverter draw?

Amount of current, withdrawn by an inverter depends upon DC input voltage and connected load. Let’s assume that 500W load is connected to inverter’s output terminals, there are no conversion or Ohmic losses, and battery is performing well giving 12V DC; then inverter will draw 500/12=41.67 amps from battery.

Will a 1000 watt inverter run a refrigerator?

Yes, a 1000W inverter can run a refrigerator. But there is one important factor to consider before attaching a refrigerator to an inverter and it is start-up current for refrigerator’s compressor. Initially, compressor withdraws power 5-7 times higher than that of nominal power. So a refrigerator with 1000*0.8/7=114W approximately can be run with 1000 watt inverter.
