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!
Looking for energy management solutions? With the growing cost of fossil fuels, there is a growing demand for alternative energy sources such as solar.
Carlo Gavazzi offers a broad range of products for improving the efficiency and reliability of your solar installation.
Their EOS system is a modular system that allows you to monitor the current, voltage, and power of your individual photovoltaic (PV) string arrays and provides immediate feedback of it's performance to your monitoring system. In addition numerous installations can be monitored through their EOS-BOX or EOS-GATE interfaces.
They also offer our ISGA Series of Grid-Tied Inverters to convert the DC power from the solar panels to either single phase (up to 5 KW) or 3 phase AC power (up to 15 KW).
They also have one of the industry's broadest ranges of Energy Meters and Transducers Contactors, and Wind Turbine Components.

11 Series Energy Meters: innovative energy management solutions! The EM10 Series is a single-phase energy meter to monitor 120VAC or 230VAC. Providing a cost-effective solution for most metering applications, this AC digital panel meter allows an effective energy measurement without the need for an external current transformer. This ultra-compact device can easily be interfaced with a PLC, thanks to its optional pulse output (1 Wh resolution). It is ideal for use in public buildings, offices, condominiums, apartments and in most facilities that require energy cost sharing and the metering of common loads.
The EM11 Series is also a 120 or 230VAC single-phase device, which provides information concerning the status of the power supply, in conjunction with energy measurement. It is the ideal solution for any application requiring a power analyzer to display and control the main energy supply. It prevents line overload conditions by switching off selected non-priority loads through its alarm output. Controlling and limiting power before a shutdown of the entire electrical system occurs makes this item irreplaceable. It is also suitable for metering most commercial and industrial applications.

Carlo Gavazzi relays and sensors too! 800-325-9653 (WOLF)
What is a programmable logic controller?According to the Crouzet website:
A logic controller is a programmable module. It can be used to control
and monitor a set of conditions according to the state of the sensors, the
passing of time and the program created using a software workshop.What can you replace with a programmable logic controller?Counters, timers, level control, relays and temperature controllers.

Reclaim normally wasted energy and convert it into 3 phase AC power!
The
RCU Series offers an affordable “green” alternative to traditional dynamic braking (DB) systems. Instead of wasting regenerative energy as heat, the RCU reclaims that energy, converting it into 3-phase alternating current (AC) power.
The energy is recycled through the AC line, resulting in increased energy efficiency and reduced energy consumption. In many applications, the amount of energy that can be reclaimed is quite significant, thus providing a measurable return on investment and short pay-back cycle relative to the cost of the RCU.
Furthermore, the waste heat generated by conventional DB often creates the need for additional cooling and air-conditioning, which can be costly. Thus, the elimination of DB waste heat is a secondary benefit of the RCU Series. In this way, incorporating an RCU in the system allows for a smaller cooling system (HVAC), offsetting the up-front cost of the regenerative unit, and additionally, reducing the demands placed on the cooling system.
The RCU is simple to install and operate, with only five connections necessary for basic operation. It incorporates LC-filtering to mitigate harmonics and an LED display for monitoring of operation and faults. The RCU is available in several sizes, and units can be parallel-connected for higher power handling.

Crouzet Millenium Application #2:
Water TreatmentDo you own a pool, manufacture swimming pools or service pools? This application is going to focus on controlling water quality in a swimming pool.
As a pool owner, manufacturer or user you need to:
- Control physical filtration of water
- Set fitering time in relation to the temperature of bathing water
- Control the pH of the water
- Control the level of water disinfection
Using the
Crouzet Millenium 3 XD10 24VDC logic controller, pH probe, ORP (Redox probe) and Pt100 probe, plus an application specific analog extension you can do the following.
Water needs to be filtered regularly to keep it clear. The higher the temperature the longer this takes.
Both pH and Redox are measured using probes submerged in pipes, a container or an analysis chamber. These probes will analyze the presence of hydrogen and chlorine ions capable of oxidizing an electrochemical couple with the probe.
This oxidation generates an electrical voltage, expressed in mV, which is forwarded to the PLC. After a calibration process the PLC converts this into values for the pH and Redox.
Additional Crouzet Millenium 3 functions are available for other requirements including lighting control, vacuum pumps for the pool cleaning brushes and more!

Crouzet Millenium Application #1:Heat PumpsMake the most of natural energy - air, water - to heat or cool a hot water system or heating circuit.Using a
Millenium 3 logic controller and NTC and Pt100 accessories you can do the following:
The heat from the warm fluid is captured by a refrigerating liquid which is compressed to give it a pressure of 40 bar and a temperature of 140°.
In a heat exchanger, this refrigerating liquid then transfers its heat to water for a hot water system or a hot water tank.
Once this thermal exchange has taken place the fluid, which has lost both temperature and pressure, has its pressure further reduced by a solenoid valve which drastically reduces its temperature even more.
This fluid is then able to receive the heat from the hot source and the cycle is ready to begin again!
