Review: If you want to make use of a small solar system you need this! - 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!
Review: Easy setup and it just works! - 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!

## Features

- 【Beneficial to Solar or Wind System】: On cloudy or windless days when your battery gets low, it will automatically switch to grid power, protect your battery.
- 【Works like an opposite direction UPS】: The ATS controller will switch to grid power when batteries votagle are lower than cut off point,it will switch back to battery power when the batteries votagle are higher than recovery point.
- 【Auto distinguish】: DC 12/24/48V,AC 100-120V 60HZ / 220-240V 50HZ auto distinguish.User can define the Cut-Off and Recovery Voltages.Recovery voltage must be higher than Cut-off voltage. Battery type: Suitable for Sealed,Gel,Lead-acid,Lithium battery and so on. as long as the voltage of your battery are within the voltage ranges in the followings.9-17V at 12V system;18-30V at 24V system; 30-60V at 48V system.
- 【Big Power】: 5.5kw(110V) or 11KW(220v),Fast Transfer time:Inverter transfer to public power ≤10ms,public power transfer to inverter ≤16ms.
- 【LCD display】: Battery real-time voltage;working status of public power,inverter and battery.⭐Note: The controller needs to connect the battery, powered by the battery and get battery power data.

## Questions & Answers

**Q: Can i have the correct wiring diagram becuse the manual is showing that the Neutral is going to the line side on the public power???**
A: White wire to white wire black to black green to green . Watch this video https://www.youtube.com/watch?v=ni0A_ZdH7aU

**Q: Can this switch be wired with two 120v (split phase power) inputs in lieu of 120v and neutral? The neutral would be hot1 the other input hot2?**
A: Yes the switch can be wire with two phases. Two hot 1(L1) will be 1phase, hot 2 (L2) will be another phase then tie the neutral (N) in with the utility neutral and the ground (G) with the utility ground. When using two phases the neutral is NOT to be wired in the switch but with the utility neutral.

**Q: is this transfer unit fused? If not what size fuse do I need?**
A: Because this ATS is rated at 50A CONTINUOUS (assumed) power, circuit breakers on its input & output need to be 125% of this value or 60A. There needs to be a SEPARATE single-pole breaker in the main breaker panel (or sub panel) that feeds 120V grid power to the ATS. If the inverter used is not already equipped with an output breaker, an external 60A breaker must be provided on the inverter's AC output (power is always overcurrent protected at its source).

**Q: Is this compatible for grid power 220v 60hz? because the grid power in our area is 220-240v 60hz.**
A: It says 220-240 50hz but it will work with 60hz as it doesn’t monitor the frequency. It’s just a big switch which switches between supplies when the batteries supplying your inverter reach a preset level.

### ⭐⭐⭐⭐ Good, but...
*by M***E on November 23, 2024*

Happy for Its 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.
