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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F12RDZ2 | | Best Sellers Rank | #141,839 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #729 in Solar & Wind Power Parts & Accessories | | Brand Name | MOES | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (1,096) | | Display Type | LCD | | Item Weight | 2.9 Pounds | | Manufacturer | Wenzhou Nova New Energy Co.,LTD | | Material Type | Gel | | UPC | 741722875483 703931915893 703931915732 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** MOES - **Color:** Black - **Display Type:** LCD - **Item Weight:** 2.9 Pounds - **Material:** Gel ## Images ![MOES Dual Power Controller 50A 5500 Watt Automatic Transfer Switch for Off Grid Solar Wind System ATS DC 12V 24V 48V AC 110V 220V. - Image 1](https://m.media-amazon.com/images/I/61TJ5L1pZML.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ If you want to make use of a small solar system you need this! *by S***N on November 7, 2023* I enjoy experimenting with solar power and I've never had a permanent solar system.

Great device for automatically switching from my inverter to utility power. Installation was easy and it worked as it was advertised right away. Because it does work as advertised, I am giving it 5 stars, but I hope for a 2.0 version. There are times though, when when there is going to be more lack of sun days then your system is designed for. I wish they could provide a way of pressing one of the buttons to force it to the opposite source (solar is forced to utility, utility is forced to solar) with disregards to the settings.....a manual override. Then you could press the button to force it back to automatic mode. I sometimes want to keep a little juice in the batteries if I know we will have several stormy days in a row, in case I do need it. Last, as previously pointed out, if your inverter shuts down for some reason, maybe a failure or blown fuse in the inverter, this device will not automatically switch over to utility power. As pointed out, you can manually add a relay, powered by the inverter AC output, to disconnect the battery from the battery input on this device. Having it built in, with an option in the settings, would make it bullet proof. ## Frequently Bought Together - MOES Dual Power Controller 50A 5500 Watt Automatic Transfer Switch for Off Grid Solar Wind System ATS DC 12V 24V 48V AC 110V 220V. - DIHOOL Solar Disconnect Switch, 30 Amp 2 Pole, DIN Rail Mount, Non Polarized, 12V 24V 48V 400V, AC/DC Circuit Breaker, RV Battery Isolator, PV Array MCB, Thermal Magnetic Trip - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/69472565-moes-dual-power-controller-50a-5500-watt-automatic-transfer-switch](https://www.desertcart.ec/products/69472565-moes-dual-power-controller-50a-5500-watt-automatic-transfer-switch) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-22*
