DC-to-AC Inverters: Off-Grid, Grid-tie, Grid-tie with Batteries

Inverters change the DC (Direct Current) electricity produced by PV solar panels into the more common AC (Alternating Current) house current electricity for normal household appliances and devices. As shown below, we offer several types of inverters to include grid-tied, off-grid and grid-tie with battery backup for the complete energy independence.

Off-Grid Inverters

Off Grid
SOLAR OFF-GRID POWER

About residential off-grid systems

A basic off-grid system consists of a renewable energy source, which generates DC power, a battery bank that stores the DC power, and an inverter. This inverter (made by Xantrex) is the center of a renewable energy system, converting DC power into clean and reliable AC electricity for you and your family's needs.

The off-grid system pictured here is a solar-electric hybrid system that offers additional automatic features. It consists of solar panels, a battery bank, a Xantrex SW Plus Inverter/Charger, a charge controller that manages battery charging, and a generator.

When the sun is up, the solar panels generate power to charge batteries and provide electricity. At night, the Xantrex inverter/charger automatically runs your electrical equipment from your battery bank. The generator provides additional back-up battery charging capability for extended periods of cloudy weather. The Xantrex inverter/charger can automatically start the generator and initiate a recharge cycle when the battery bank is depleted, or a load is too large for the batteries to support independently. You can even have a connection to the grid should you want to use utility power.

Sharp 3500 Sunvista Inverter
The Sharp intertie inverter has proven itself over several years and tens of thousands of Japanese installations. We're pleased to introduce it to North America. Offering up to 3,500 watts of output, with maximum power point tracking, the Sharp is unique in that it uses three separate input channels. Each channel operates independently, making the most of the array attached to that particular input. PV arrays can face different directions, with different numbers or even brands or sizes of PV modules to make the best use of available space, and it will still harvest maximum output from each module. All modules within a single input channel must match, and all must face the same direction. This inverter also lends itself to starting with a smaller system with lots of room for future expansion. With most 24 volt-nominal modules, strings of 5 to 7 modules are acceptable. With 12 volt-nominal modules, strings of 9 to 14 are usually acceptable.

The light gray Nema 3R case can be mounted indoors or outdoors. Inverter output lands on a 20A/240V circuit breaker in your main breaker panel. It has automatic active cooling fans to allow full power output under very hot conditions up to 105 degrees F. During even hotter conditions it will limit power output to the most efficient setting possible without overheating. An interior wall-mounted LCD display is included. It shows instantaneous output, cumulative output for one year, and total CO2 abatement. (A great feature for bragging rights.)

UL and IEEE approved. Requires a high-voltage DC Disconnect between PV arrays and inverter for electric code compliance. Lightning protection is optional, but recommended. Size is 23.6"W x 17.7"H x 7.6"D, weighs 62 lbs. 5-yr. mfr.'s warranty. Japan.
