Inverters

Sine Wave Inverters

Sine wave inverters are the ultimate inverter. They produces electricity similar to or better than utilities with virtually no harmonics.

• Will run any appliance - typically used to run appliances sensitive to other waveforms like computers and electronic entertainment equipment.
• More expensive than modified sine wave inverters

Modified Sine Inverter

Modified sine wave inverters are a popular option with slightly compromised wave (some harmonics) at a lower cost. They approximates a true sine wave with low harmonics that do not cause problems with household equipment.

• Main disadvantage is peak voltage varies with battery voltage. Inexpensive electronic devices with no regulation of power supply may behave erratically when battery voltage fluctuates.
• Not all modified sine wave inverters are created equal. A high quality modified sine wave inverter such as the Xantrex DR series will run 99% of loads without a problem.

Portable Inverters

Portable battery / inverter systems provide the ultimate in convenience in an easy, all-in-one package.

Power Panels

Power panels are the ultimate in installation convenience. Choose from a wide variety of inverter, controller, transformer and other options. Have the whole unit custom-assembled for your installation.

Grid-Inertie Inverters

• Designed to “sell” power back to the utility when there is a surplus.
• Certified products available off the shelf and easy to use.
• Available with or without batteries depending on your needs.
