Questions & Answers


Please help me understand how the modules work.

Asked by Dennis2000 January 25, 2015

your assumption about the modules is correct however so far I have not been able to get them to communicate with the transfer switch .and the instructions are poorly written..I can't even figure out by their own instructions whether the damned thing is wirelessly communicating or not.. but so far I have no way to make it work .

Since I am disabled I need to ask this, I have a GE double wall oven, in addition I have a GE mic...

Asked by Gjp May 30, 2018

At this time there is no such thing as a symphony 3 transfer switch. I would recommended adding a symphony 2 module to any 240 volt high wattage appliance (A/C, electric range or oven, hot water heater, etc.)

Would this be good for my fish tank,?

Asked by Jackie September 12, 2017

That would depend on what generator your using and the electrical requirements of your fish tank. Your best resource for that information will be through a local Briggs and Stratton service center.

Where's the Manual

Asked by RobertBaltimore November 20, 2015

Please locate a product model number and work with your local technician.

What modules do I need for a double wall oven and an electric dryer?

Asked by Todd August 31, 2011

Greetings Todd, My name is Tom, also known as HD116 here and at Home Depot's How to Community found at the site above. Thank you for your question. You could hook either your wall oven or your dryer up to the other module. The GE 13 Watt generator 49324HD features Symphony 2 technology which allows you to create a "Hierarchy" or choose which high voltage appliances you wish to run in the order you choose when demand occurs. Each additional appliance does require a module, and the system can monitor up to 8 modules. If you have any further questions please contact GE's customer service for Standby Generators directly at 1-888-575-8226.

What about loads without a module?

Asked by Dennis2000 August 21, 2015

Please work with your local technician for further assistance.

Can i use this with an older b&g transfer switch?

correct installation of modules
this module is a great addition to your generator for load management. not to be used for HVAC equipment. That is what low voltage modules are for. high voltage module such as this one is great for managing your loads to any appliance up to 50 amps 120 volts or 240 volts. make sure your installer leaves you manuals with your new equipment. every component has a manual that comes with it. appliances for this module would be dryer, range,water heater, cooktop, etc

Flaky, keeps disabling my heat pump, even when not on generator
Quality :
I got this box along with my GE generator, and while the idea mat be good, the implementation is lousy. While I got no manual for it (nor can I find one anywhere on-line), the installer explained that it should: 1) Keep the heap pump powered when on mains power (it doesn't always do that) 2) Communicate over the power wires with the generator controller, to insure that my whole house system doesn't over load (indicator says it doesn't have communication while on mains power, but I have no idea whether this is normal) 3) Shut off the heat pump when I'm drawing too much from the idea if it does that, because we're careful not to overload it in the first need to bake or do wash during power outages. So, we were pretty cold last night until I got up at 3AM and shoved a piece of plastic to close the relay and get my heat back. Now I'm waiting for the installer to call back.
