Marantec's ultimate garage door operator! Designed and built in Germany with highest standards for safety and quality, Synergy 380 is the first residential garage door operator system that offers integrated LED lighting. Not only is LED lighting very energy efficient but with a life expectancy of over 30,000 hours you will never have to replace a burnt-out light bulb in your garage door operator again. LED extension kits are available to double the lighting capacity from 500 Lumens to 1100 Lumens. An integrated battery back-up system ensures that you can open and close your garage door in case of a power outage. As an additional benefit, the LED lights of the Synergy 380 will continue to work when the opener is running on battery power. A pre-tensioned, 2-piece belt rail system allows for an extremely easy assembly, while a 1.1 HPcs motor provides for an amazingly quiet and powerful operation for heavy carriage house or wind loaded garage doors. Synergy 380 offers programmable door travel speeds up to 7 in. per second and can be set separately for the up and down travel cycles. An integrated LCD display guides you through the simple 3-step programming sequence while the Synergy 380 automatically calculates and maintains the force and sensitivity levels required to open and close your garage door. Considered the safest and most reliable garage door operator system available, Synergy 380 will provide you with many years of reliable and maintenance free performance.

Rated 4.0 out of 5.0 by Marantec Synergy 380 Garage Door Opener This opener was easy to install. The components are made from quality materials. It has a very quiet motor, but it is not a true 1.1 HP motor. The lights, even with the added cost of the additional LED lamps are poor. I certainly expected brighter illumination. The operation of this opener, even with setting it to the faster speed, is slow. Performance of the remotes is good. Programming is a snap. March 25, 2015
Rated 5.0 out of 5.0 by Well Made with all the Bell and Whistles My house came with a Genie chain drive opener which has given me more than a few problems over the years so I eagerly jumped at the chance to upgrade. The Marantec Synergy 380 Belt Drive Garage Door Opener is a top of the line feature rich residential garage door opener. It arrived nicely packaged and undamaged. I've done numerous projects around my home but never installed a garage door opener. Seeing all the parts was a little intimidating but thankfully Marantec includes a complete installation guide. The Synergy 380 is for use on sectional garage doors but since garages vary in size, there are a few different install scenarios covered in the guide. I read it at least three times and took measurements before diving in. The install was not that hard but make sure you have the necessary tools. It was a little easier for me because I was able to place the new rail in the same place as the old one. I was also able to use the mounting brackets from my old opener. The Synergy 380 is a fair amount more expensive than the top models of other brands but there are a number of things that set it apart from the rest. First, the 1.1 HP motor will handle just about any residential garage door out there. Second, the LCD display takes the guess work out of programming the unit. Next, the LED lighting saves energy (although it is a little bluish) and produces less heat. The keyless entry unit has illuminated keys and is the nicest I've seen of any brand. One of the best features are the small remotes that can be placed in the car or on a key chain. I've never liked keeping garage remotes on my car visor. All someone has to do is get into your car to then get into your garage. Placing the remote on the key ring is an excellent idea. Let's not forget the battery backup. Marantec's battery fits seamlessly into the unit. This is something that may go unused for months but when the time comes it's worth its weight in gold. The Synergy 380 has worked like a charm since I programmed it. It is without a doubt much quieter that my old chain drive opener. While doing the install I did have a problem getting the motor head to fit on the rail. I contacted Marantec via email and received a reply within five minutes (yes five minutes). They also had the part I needed out to me that same day. The Synergy 380 is a well made product with an excellent warranty but it's nice to have exceptional customer service there if you need it.

Rated 4.0 out of 5.0 by Replaced M4770 with this. Got this to replace an 8 year old marantec M4770 that was malfunctioning. Took a bit of re=engineering because the mounts have changed considerably from the M4770. The 380 mounts are only on rail, the M4770 mounts were on the unit itself. In other words the 380 hangs off the end without direct support. The header mount for the rail has also changed, so basically buying from the same mfg did not save me any time. Had to do a clean install anyways. Did not like the two piece rail, it bends significantly more than the old 1 piece rail and is of lighter construction. Also not a fan of the cheap LED lights on the unit. I got the LED expansion kit which doubles the LED strips on each side and the lighting is nowhere near the old 60w x2 bubs. The LEDs are cheap and blue tinged, not pure white light as you would have with cree or similar LED's. The opener is quiet, my wife believes it is better than the old M4770. The 380 has a small LED display which the 4770 did not. The 380 also comes with battery backup in the unit, the 4770 did not. I have a very heavy wood sectional door and this unit handles it just fine. The 380 requires a stop in the rail that is screwed permanently into place, the 4770 did not. The rail from the 4770 can be used with this unit according to marantec support, but you must use the stop regardless. The openers, wireless stationary keypad and wired controls are all interchangeable with M4770 315mhz, so programming and setup was a breeze and now I have spares in case I need them. January 20, 2015
Rated 5.0 out of 5.0 by Best garage door opener I've ever installed I am a do-it-yourselfer, so I installed this garage door opener myself in about 3 hours taking my time. I did call tech support once for a question, and they answered it quickly. They have great phone support. I am pleased with the built-in LED lighting which adds to the value of this opener since you won't have to worry about changing light bulbs, or worry about which kinds to replace it with. The remotes work at a good distance, the unit is quiet which I appreciate, and the keypad has a nice feel to it. Very solidly built, and I expect it to last for a long time. March 16, 2015
Rated 5.0 out of 5.0 by All the Garage Opener Bells and Whistles My old opener was really old. I was glad to be able to upgrade to this brand new one. I remember trying to replace an opener years ago and the memory was not good. So I hired a pro this time. They could not fit me in for over a week. It was worth it. It took him 2 hours and he had to call Marantec twice for answers to questions that were not typical of other openers and not addressed in the instructions. They guided him right away. Very good cust. svc. I like that this opener is very quiet. You only hear my door squeal, which I never noticed because my old opener was so noisy. It also has LED lights and a backup battery pack. It comes with 2 remotes and keypad for outside. July 28, 2014
Rated 4.0 out of 5.0 by Doesn't work well with Homelink Pluses: Quiet Smooth Soft start and soft close Works effortlessly on heavy solid double door Minuses: LED lights are dim and blue-bought the $18 upgrade kit to made them a little brighter Works only intermittently with 2013 Lexus Homelink, about half the time, never had a problem with Homelink before on old opener (Liftmaster). Door opens/closes slowly under default settings, but speed is easily adjustable and under fastest setting it has what I consider normal speed. Does not have a motion detection light sensor that my old opener had. Bottom line: a great smooth powerful and quiet door opener. Wish it had standard bulb base that an LED bulb could screw into. Homelink does not consistently work. Contacting Customer Service to see if the issue can be resolved. March 19, 2015
Rated 5.0 out of 5.0 by Fantastic product! This product is well made and speaks quality throughout. The manufacturer has provided everything for the installation to be as easy as possible. Let it be known that the perforated L-brackets for assembly suspension off the ceiling were not included, which is understandable. Instructions are clear and easy to follow. IMPORTANT!!! The rail, with the belt drive shipped unassembled and does need to be assembled. This step seems to have confused many so her are my two cents... Lay the rail on the floor, make sure that the U-channel is in place prior to going further. Once U-channel is on the rail, hold one half of the rail against the floor and swing another half open. Both halves should be touching the floor at all times during this step, and the moving half should be traveling clock-wise or counter clock-wise depends which one is being moved. Pretend as you are moving a minute hand of the clock...As you are doing this, make sure that both ends of the rail are touching each other at the split (in the middle). As you keep opening the rail to its final, straight, position a tension from the belt will begin to "hold" the other half from going further. That's to be expected and is normal. Slowly, continue to push the other half forward toward until it is aligned with the first half. In clock analogy, one half will be looking at 12 o'clock and the other at 6 o'clock. The belt does have some "give" and will stretch enough to get through this. Once the rail has been made into one straight line, align each half so that there is no overlap at the seam by slightly tapping one of the rails with the rubber mallet. Secure the u-channel at the seam. Once installed and fired up, the unit is working as expected producing extremely low hum of motor. I think my garage doors make more sound than the unit itself. Self-learning technology is great and ensures that the door stops precisely where it should. Overall I am very satisfied with my choice and would definitely recommend to anyone who is looking to buy one. Absolutely worth every penny. March 12, 2015
