What size power inverter should i get

Circular saw, bench grinders and other power tools can be compared to running a welder on solar power in that the watts per hour does not tell the real story. A router can use up to watts an hour, but only if it runs continuously for 60 minutes. But most power tools are not used that way. Usually you turn on a table saw, cut some wood for a few minutes and turn it off. After a few minutes you cut another piece and so on.

The same goes for other tools. While the watt hour requirements are high, it is unlikely the demand would be reached. It could happen of course if you use different tools. You might start with a circular saw then a belt sander followed by a drill etc. In this case you can easily reach thousands of watts, but again it is unlikely the power tools will reach their maximum watt they are stated for. Also keep in mind that surge watts are only for a second or even less. A circular saw with surge watts is not going to tie up the inverter.

It just needs a second to startup and then it will only use watts max. Compared to a refrigerator, motor or freezer, we cannot give an average of how long an inverter will last. This is because power tool usage differs widely from case to case. On one day you might use several tools to build a desk. On another you might only need a drill to make a small repair. The most practical way to go about this is to get the largest inverter you can afford.

Your inverter can never be too big for these tools. And if you find yourself with extra inverter power available you can always use it to run other appliances. A pure sine wave inverter is recommended for power tools. It is more energy efficient than modified sine wave inverters and it does a better job of reducing energy loss. We suggest the heavy duty Giandel as it is one of the best pure sine wave inverters available.

Given the power demand of these tools, you need an inverter that is as effective as possible. If you have an energy efficient solar system, the inverter should be too. Another reason to use pure sine wave is modern power tools may not even run on modified sine inverters.

You might be able to make some of them work, but the tool will not produce optimum results. And forcing a table saw or any power tool to run on something it was not designed for could damage the equipment.

An inverter in a grid tied system does not need a battery to run any appliance or tool. An off the grid system however, requires batteries to power the inverter. A grid tied system means the inverter and solar panel system are connected to the company electrical grid.

The grid functions as the battery, as that is where any excess solar power is stored. The inverter is connected to this system so you can use any power tool — or any electronic device — without using batteries. An off the grid system is independent from any power utility.

Note: If you intend to use power tools for commercial use, or any load of W for more than 1 hour regularly between battery recharging we recommend installing an auxiliary battery to provide power to the inverter.

This battery should be a deep cycle type and sized to meet your run time expectations with the vehicle engine off. This will lengthen the time before your batteries will need to be recharged, giving you a longer time that you can run your appliances.

Home Advice on selecting an inverter Before choosing an Inverter for your needs, we recommend you read this page and note the definitions explained. This will help you understand why certain Inverters cost more and others less. These definitions can apply to all makes of Inverters whether they are supplied by us or not. What size inverter must I use? What is the difference between modified sinewave and pure sinewave? Inverters have either modified sinewave squarewave or pure sinewave output. Some of its advantages are as follows: Output voltage waveform is pure sine wave with very low harmonic distortion and the same as the ESKOM supply Inductive loads like microwave ovens and motors run correctly, quieter and cooler Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and answering machines Prevents crashes in computers, unreadable print outs, and glitches and noise in monitors It can be efficiently electronically protected in overload, overvoltage, undervoltage and over temperature conditions Modified Sinewave Inverter The Modified sinewave inverter has limitations.
