Product Instroduction
This dual power transfer controller ATS-11KW is used between an off-grid system and public power.The controller is separately connected with public power,inverter,battery and load.On the top of the controller,there is an on/off switch,please turn on the controller after ensuring all cables are well connected.
The ATS power transfer controller provides reliable operation of an inverter and AC utility power in one compact device. The ATS switches automatically between the AC utility power and the inverter, while protecting the inverter against external Voltages.
Works like an opposite direction UPS
- The ATS controller will switch to grid power when batteries are lower than the user define.
- Auto distinguish:DC 12/24/48V,AC 100-120V 60HZ / 220-240V 50HZ auto distinguish.
- User can define the Cut-Off and Recovery Voltages.
Beneficial to solar and wind system
- When cloudy or windless days and your battery get low,automatic switching to grid power,Take over your battery.
- BIG POWER:5.5kw(110V) or 11KW(220v),
- Fast Transfer time:Inverter transfer to public power ≤ 10ms,public power transfer to inverter ≤ 16ms
- Please tie the ground wire together.
Application Area
- In applications where there is a stand-alone solar or wind system with an available AC mains supply(utility power),one can choose to use the energy stored in the battery(IES) first and when the inverter disconnects due to a low voltage battery,the controller automatically transfers the loads to the mains(utility power).
Adjustable Cut-Off and Recovery Voltages
1.LV-SW:setting the switching voltage function.
2.BAT-V:normal displaying battery voltage.
3.HV-SW:setting the recovery voltage
4.12V,24V,or 48V:displaying after the system indentification.

6.Right arrow:shows low voltage switch to mains status.
7.Left arrow:shows the low pressure is restored to the inverter state.
8.LCD red no function control display,fixed display after power on.

Works great for my home made solar set up.Switches over really fast when needed to from solar to grin.

From what I can garner, the unit draws 7-8 watts of idle power consumption. The transfer switch worked seamlessly upon initial testing. When I forgot to turn the PV input back on, the unit had already switched to shore power by morning. Since my batteries were run nearly all the way down, with little sun the last few days the Moes unit has worked flawlessly switching back and forth from grid power to battery. Very good and easy setup after tons of research into a solar battery transfer switch. Easy to use, settings are a breeze and it just works!

Après 15 jours d'utilisation, je peux vous dire que c'est un super appareil.Temps de transfert extrêmement rapide ( aucune micro coupure).Maintenant reste à voir dans le temps si il garde ses performances.

Great product, makes for smooth transition from solar power to grid power when your battery bank is low in energy. Then automatically switch back to your solar power when your batteries are chargedGreat peace of mind. I use mine to power the fridge, the freezer, the water pump and the sump pump.It's very important to never have power outage for theseI warmly recommend this item for your peace of mind.

Happy forIts been little over two years since I bought it, I dint find anything quite like it. Super easy to install, granted you have a basic understanding of electricity. Extreamly reliable and worry free. Just install and watch the magic of automatic power transfer. Bearly notice the changes. Would have give it a 5 star but I wished it would at leats last 5 years. Any way, im not dissapointed. Great product. I bought at $133.00 Its now $79.00 . I'm defenetly buying another on after I write this review. Still seems to be the best product out there. Other with similar capabilities are a bit more expensive. By the way, what happened to mine is that the output power port died/fried.

(update at bottom... had to drop it to one star, no relay validation means the two sources can be cross-linked).The unit works decently well, but I can't give it 5 stars because it isn't really a "reverse" UPS or anything of the sort. It only monitors the battery input voltage to determine when to switch. It does not monitor either of the line inputs at all.This means that if the battery voltage is fine, but the inverter gives up the ghost, this ATS will not switch from inverter to mains. And similarly, if voltage or frequency of the "inverter" input goes out of spec, this unit does not monitor that and will not switch to the mains. It goes strictly by battery voltage.It would be a whole lot more robust if the unit also monitored the "inverter" input.If battery power is lost entirely, the unit powers down, but if the unit had already switched to the mains it will remain on the mains while powered down. However, the unit does not remember its last state when it powers up again so when power comes back the unit will not wait for the battery voltage to reach the recovery voltage. Instead it will switch back to the inverter if the battery voltage is above the low-voltage point, even if it is still lower than the recovery point. I'm not going to dock a star for this behavior but it is worth noting.--There are a few other quirks. The battery monitoring inputs are high-gauge (small wire) screw terminals, and to be totally safe you not only have to tap-off your battery to go to these inputs, you also need to put a little 2A fuse in-line so those high-gauge wires don't become a line of fire if they happen to short.And, as described in the manual, the unit is powered by the battery input. This is also a bit of a problem if the battery goes completely dead, so you have to make sure that that does not happen. I won't dock it a star on that account, but it would be a whole lot nicer if the unit could power itself from any of the inputs.There are no screw terminals for GND, you have to tie your GNDs together externally.--I took it apart to check whether there was a relay state validation feedback circuit, which is absolutely required for any sort of automatic transfer switch. There appears to be none. It is articulating the relays in the blind which means that when the unit eventually fails it will likely cause the two power inputs to be cross-linked to each other... which is extremely dangerous. Pictures included.This make the unit a complete non-starter, a failure could cause a fire. Dropped to 1 star

I enjoy experimenting with solar power and I've never had a permanent solar system. The main problem with using solar power as a hobby is that when your battery runs low, your inverter and all the devices connected to your inverter will turn off too. This makes it really difficult to reliably use the power you generate, at least till I learned about this little gem. With this ATS you can connect your grid power, and inverter as an input, a plug (or what ever you decide to use) as an ouput, connect a voltage monitoring cable to your battery (from the ATS), and this device will automatically switch between your inverter and grid power depending on your batteries state of charge without ANY interruption do your devices. If you are watching TV, or gaming on your computer during the switch you will not even notice it. The best part is you get to determine the low voltage at which it changes to grid, and the high voltage when it changes back to your inverter. This means that you can run your devices off your solar panel/battery and then when that power is used up it will swap back to grid power. The next day when the sun comes up and the battery charges, you are back to solar power. This is great way to make permanent use of smaller solar systems. The other exciting thing is that you could (if your batteries can support it) add more and more panels to the system and get usable solar power when the sun is up without having to spend a ton of money on batteries.There is feature i wish this device had, mainly the ability to manually choose if you want to use grid or solar power, but it's not a deal breaker.This device can show an incorrect voltage reading (might be off by .2 volts, but if you hold the up and down arrows for 3 seconds you will be able to adjust the offset.I have used this system for over a week now and it's working flawlessly, i wish i had known about it a long time ago!
