We carry many different sizes, and several brands of power inverters. See our inverter page for specifications on
each of our models. The size you choose depends on the watts (or amps) of what you want to run (find the power
consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model
than you think you’ll need (at least 10% to 20% more than your largest load).

Example: You want to power a computer with a 17″ monitor, some lights, and a radio.

• Computer:
  300 Watts
• 2 – 60 Watt lights:
  120 Watts
• Radio:
  10 Watts
• Total Needed:
  430 Watts

Advantages of Pure Sine Wave inverters over modified sine wave inverters:

a) Output voltage wave form is pure sine wave with very low harmonic distortion & clean power like utility-supplied
electricity.

b) Inductive loads like microwave ovens and motors run faster, quieter and cooler.

c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, Game consoles, Fax, and
answering machines.

d) Prevents crashes in computers, weird print out, and glitches and noise in monitors.

e) Reliably powers the above devices that will normally not work with modified sine wave inverters.

You can use these formulas to calculate how long your appliance will operate on your battery.

For a 12 Volt System::

(10 x (Battery Capacity in Amp Hours) / (Load Power in Watts)) / 2 = Run Time in Hours

For a 24 Volt System::

(20 x (Battery Capacity in Amp Hours) / (Load Power in Watts)) / 2 = Run Time in Hours
