[what does this do?]:
This item is for grid tied homes to eliminate or reduce their electric bill without going the expensive grid-tie route or having to get permits. (All state, county, city laws are different, check to see what your laws are in your area!!!).
This ATS allows you to run your solar system in parallel with utility at the same time (THIS IS NOT GRID TIE!!! OR NET METERING!!) This gives you power when the grid is down too!
Most importantly this product physically prevents backfeeding to the grid utilizing an industry standard double pole double throw (DPDT) relay.
This means you can safely run your ENTIRE home, or select circuits (i.e. if you have a 110v inverter you can run all your 110v circuits on the solar and all the 220 on grid or mix 110 and 220 circuits). This ATS monitors the solar system inverter output. Once voltage is detected from either the inverter, a charge controller (available in 12, and 24 volt DC and 110 / 220 volt AC relay coils) or generator 110/220 volt output it switches off utility.
When the battery level is low and your inverter or charge controller load (not all have this) goes to your set threshold it switches over (without loss of power) to grid. When the sun comes up the next day and your batteries reach your set threshold it instantly switches back to solar (without power loss). Fully automated solar but you can still use the grid when ever you want or to supplement.
This is all accomplished without back feeding to the grid utilizing a double pole double throw relay (required by law). This is installed on your side of the meter so you will not have to pay grid tie fees and grid tie solar panel fees! The Utility can't even tell you are running solar (both old school dial meters and smart meters).
Available in 120 amp (300 amp surge) 110/220 volt relays.
IF YOU *DO NOT HAVE* A CHARGE CONTROLLER THAT ALLOWS VOLTAGE / LOAD ON OFF SETTINGS WE SELL AN ACCESSORY UNIT (SEE LAST PICTURE) THAT ALLOWS YOU SO SET YOUR ON VOLTAGE AND OFF VOLTAGE OF THE RELAY FOR 12 AND 24 VOLT SOLAR SYSTEMS AND ALLOWING IT TO TURN YOUR INVERTER ON AND OFF AUTOMATICALLY.
This has a built in relay and electronics to work with any inverter switch. ***THE ITEM DESCRIBED IN RED (AND THE LAST PICTURE) IS NOT INCLUDED IN THIS sale!!!***
