FAQs

The price for an ATS will vary dependent on the size, voltage options, and enclosure type. The purchase price of the ATS also does not include the cost of installation or any necessary wiring.

On product pages there is a price bar that shows “Our Price“. If there is a base price for the product the price will show below the label. If there are options available for this generator then you will see yellow bars below the price bar. If you put your mouse on the options bars, the bar will drop down and show you the options and their prices. If you select an option, the price of the product will automatically change to include the option price. You can remove the option by clicking on its window and selecting the yellow header.

For manual generators, the ignition switch is wired to the ATS and the auto switching off is controlled by the ATS. For automatic generators, the generator remote signal is wired to the ATS and the ATS is configured for auto generator. The rest of the generator operation is managed by the ATS.

The transfer time delay is programmable by the user, it ranges from 1-250sec, refer to the user manual.

Yes. Most of the ATS models are equipped with special load functions were this kind of loads can be connected and, the power requirement to operate the special load can be configure on the ATS either utility or generator or inverter, again depending on the model.

There are varieties of ATS depending on the load requirement. For domestic application single phase ATS is available, for commercial and industrial application 3phase system is available and for telecom application 3phase system with dual generator is also available

This can vary by the type of ATS and depends on the number of circuits you would like covered.
In a partial home application, the ATS is installed similarly to a subpanel or manual changeover, and the circuits that are covered by the generator are moved either into a circuited ATS, or are installed in a subpanel that is protected by a non-circuited ATS.
In a whole home application, the ATS is installed between the incoming utility power source and the home’s distribution panel.

Most of the engine/generator controllers used today are digital and are designed to provide control of the generator set. The controller system monitors the operation of the engine and generator functions. Typical safety items include low oil pressure, high temperature, engine start over-crank, over/under frequency (speed), low coolant level etc. Modern digital controllers for residential or small business applications are typically a simplified LED indicator a start-stop button with or without auto-start. If the generator has auto-start, the controller can be used to interface with an ATS to start and stop automatically. Usually manual controls are provided on all generators including those with auto-start. Advanced controllers provide real time monitoring of volts, hertz, and amperage in addition to the basic engine/generator safeties and auto-start functions.

First, the fault on the ATS is displayed with troubleshooting method for the touch screen models. For the LCD model the fault is displayed with a fault code which refers the user to the operational manual to interpret and troubleshoot accordingly and for the switch operated type the fault LED flashes in numbers, this numbers of flash indicates the fault code which then refers the user to the operational manual for further interpretation.

Yes. The L400 and T400 are capable of controlling inverters. The inverter will be wired to the ATS, hence the ATS recognizes it as the 3^rd source of supply making it priority 2. In other words when utility power supply is lost the ATS starts up the inverter and powers the load, and if auto generator is used, when the inverter battery is weak the ATS starts up the generator and the load is powered by the generator and inverter starts charging the batteries, when utility supply is restored the generator is shut down and the load is powered by utility supply.

The ATS unit has LEDs on the front of the unit to show which source (utility or generator) is being used at the moment and what sources are available. With the local display option, you get the ability to see either Volts, frequency, or other status parameter.

Yes, but derating factors needs to be checked. Notice that switching mechanism operating temperature limit is 50°C, which often becomes the limitation.

Yes. The L and T Series ATS are capable of automatic water pumping with level transducer installed on the water tank, which is continuously monitored by the ATS and initiates a start stop of the pump depending on the water level. Also, the power requirement to operate the pump can be configure on the ATS either utility or generator or inverter, again depending on the model.

ATS stands for Automatic Transfer Switch, but it can also be referred to as an Automatic Mains Failure system, or AMF
for short.

The ATS is an essential part of the home backup system. Its primary function is to prevent your home from being powered by utility and generator power at the same time. If utility power is lost, the ATS control panel senses the loss, starts up the generator and transfer the load to generator so it can begin providing power to the home, the reverse occurs when utility power is restored.

Generally, No. Most portable generators do not have the capability to auto-start. The generator must have an electric starter, electric choke (for gasoline units) and the start and stop controls and safety sensors to be able to start and stop automatically. The cost of auto-start and safety equipment generally increases the price of portable equipment so much that no one would buy them, so they are not manufactured.

This is acceptable for peak wattage but not recommended for running wattage. Pulling more than the rated wattage through the ATS could burn out the cables, overheat the main wiring in the transfer switch and cause a fire. To ensure proper safety precautions, a suitable double pole breaker should be installed between the generator and the ATS when the running wattage of the generator exceeds the rating of the ATS.

Diesel engines require routine maintenance for long-life service. The normal maintenance requirements are about the same as owning a diesel-powered vehicle – oil, oil filter, air filter and fuel filter.
The engine will need an oil and fuel filter change every 250 to 500 hours depending on the operating. The ATS is designed to monitor the operating hours of the generator and trigger a maintenance alarm to notify the user on maintenance due. The maintenance hours can be set on the ATS based on the owner’s requirement.

If you are interested in an Automatic Home Standby Generator, you should work with a licensed electrician/installer to determine the proper ATS. If you do not have someone you are working with, Accretive technology offers a free In-Home Assessment with our professional. They will evaluate your specific needs and make a recommendation that fits your budget. Click here to schedule a free in-home assessment. During your consultation you will receive the personalized attention and detailed evaluation you need to find a solution that works for your need.

Generally no. Most modern ATS have a manual mode so they do not switch until you change the switch position to transfer or automatic. New switches are electrically operated and when they change position, they use power from the utility or generator to move. They DO NOT have handles on the sides of them like old fashioned switches.

ATS are available through our Accretive technology Authorized Dealers or through a local retail store. An in-home assessment can also be a great place to start if you are not sure what size you need. Click here to schedule a free in-home assessment for an automatic home standby generator
