Two weeks ago my response would have been 'heck if I know' but now that we have a line that carries them I can answer the question.
Of course my first action when hearing about grid tie inverters was to ask my old friend 'Google'. Which brought me to another pal,
Wikipedia.
To start with, you might be calling them something different. I've seen GTI (grid-tie inverter), PV inverters, solar inverters, synchronous inverters, grid-interactive inverters and a mix of all of the above.
The purpose of a
grid-tie inverter is to convert direct current (DC) into alternating current (AC) and send that electricity into an existing electrical grid.
Grid-tie inverters are popular in solar panels and small wind turbines because that power is being used to power homes and businesses.
You might ask why these are becoming popular... great question and one I asked myself!
In many places you are now able to sell your energy to the utility grid. There are a number of ways to do this so that would need a separate blog (and plenty of additional research by me).
Regardless, check out our our new single phase solar inverters (GTI, PV inverter, etc.) from
Carlo Gavazzi, the ISGA series.
Marshall Wolf Automation is your authorized industrial automation distributor for the complete line of Carlo Gavazzi sensors, relays, industrial DC power supplies, monitoring relays and now... grid-tie inverters!
Transformers are AC to AC devices... you cannot transform DC. Transformers convert AC electricity from one voltage to another voltage, usually with little loss of power.
The input coil on a transformer is called the primary and the output coil on a transformer is called the secondary.
Industrial DC power supplies, on the other hand, reduce high voltage (generally AC) to a safer low DC voltage.Do you need a
transformer? We are authorized industrial automation distributors for the complete line of Micron transforms. You might also call these CPT's, control power transformers, step-up transformers or high inrush transformers.

After reading this maybe you have decided what you actually need is an industrial DC power supply to reduce AC voltage to a lower DC voltage?
Not a problem, we have a large inventory of VDC output power supplies ranging from 5 to 960 watt.

Carlo Gavazzi has released their ISGA series of Grid-Tied PV Inverters!
The
Carlo Gavazzi ISGA series features a transformer-less design which does not incorporate or require a cooling fan.
Cooling fans have moving components which eventually fail... this means not having one will give you a longer, maintenance-free product life span.
The primary markets for PV inverters include residential, commercial and light industrial.
The
Carlo Gavazzi ISGA series is available in 2kW, 3kW, 4kW and 5kW output sizes. The inverter has an output efficiency up to 96.4%!
Other features of the
Carlo Gavazzi ISGA series include:
- Low MPPT input voltage
- One or two MPPT inputs
- High efficiency rating
- Transformer-less design
- Fanless design
- Informative mimic panel display
- Free graphical user interface software
- RS232, RS485, Ethernet or USB communications

Power-supply manufacturer Carlo Gavazzi recently released a series of switching devices the company deems "economically friendly," the RMD Hybrid Relays. The product provides mercury-free switching, designed for controlling heating elements inside of food ovens, warmers, fryers, rotisseries and other food equipment. It's capable of switching up to 20 cycles per minute, with a 4 million electrical cycle life expectancy. 
The RMD Series combines solid-state technology and electromechanical relays to provide a hybrid relay. This means that there is virtually no contact arcing, which results in prolonged relay life and much less emission inside of the panel. Another benefit of hybrid technology is a full amperage rating at elevated operational temperatures. While most conventional switching devices are rated at 25-40 degrees Celsius, the RMD Hybrid Relays are fully rated up to 60 degrees Celsius. The RMD3H switches heaters on three legs while the RMD2H is a lower-cost alternative, as it switches two poles and the third pole is directly connected between L2 and T2. Additional technical features include:
- Two- (for single and three phase circuits) and three-pole arrangements
- Rated for 4 million electrical cycles
- Rated for up to 20 cycles per minute
- Two output voltage ratings: 240VAC (VL-L) and 277VAC (VL-N – 480VAC with Neutral)
- Three common control voltages: 24VAC, 120VAC, 240VAC
- Two amperage ratings: 30A up to 70 degrees Celsius, 40A up to 60 degrees Celsius
- Similar mounting to Mercury Displacement Contactors
- Mercury-free, RoHS compliant, cRUus recognized
