Enables maximum use of solar power without having to check levels and switch over manually. Also protects batteries from over discharge. ## Features - 1.★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. - 2.★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. - 3.★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. - 4.★Big Power:5.5kw(110V) or 11KW(220v),Fast Transfer time:Inverter transfer to public power ≤10ms,public power transfer to inverter ≤16ms. - 5.★LCD display:Battery real-time voltage;working status of public power,inverter and battery. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F12RDZ2 | | Best Sellers Rank | 32,892 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 298 in Charge Controllers & Accessories | | Brand | MOES | | Colour | Black | | Country Of Origin | China | | Customer Reviews | 4.4 4.4 out of 5 stars (1,047) | | Display Type | LCD | | Item Weight | 2.9 Pounds | | Manufacturer | Wenzhou Nova New Energy Co.,LTD | | Manufacturer Part Number | NV-001 | | Material | Gel | | Model Number | NV-001 | | UPC | 741722875483 703931915893 703931915732 | ## Product Details - **Brand:** MOES - **Colour:** Black - **Display type:** LCD - **Item weight:** 2.9 Pounds - **Material:** Gel ## Images ![Dual Power Controller 50A 11000 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) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: uk- 240v earthing. Should the load earth and mains (grid) earth be connected but NOT the earth from the inverter?** A: They should be earthed together, as per instructions **Q: What happened to earth cables? as there aren't any connections on the ats unit?** A: No you need to connect to main earth **Q: does this product can be use in philippines 220V at 60hz** A: Yes, can support 220V, 60HZ **Q: can you make the primary power as grid and if grid fails then goes directly to inverter?** A: For the time being, we only support the battery as the main power source, and switch to the grid after the battery level is lower than the threshold. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by S***N on 21 April 2026* Works well ### ⭐⭐⭐⭐⭐ Easy install and works as described *by B***N on 17 April 2024* Very well made and intuitive in use. Enables maximum use of solar power without having to check levels and switch over manually. Also protects batteries from over discharge. ### ⭐⭐⭐⭐ Clever, but it does have some issues....... Read on! *by R***Y on 29 May 2025* Unlike most Automatic Transfer Switches (ATS) that switch over to an alternative power source when the existing power source ‘fails’, this ATS switches over automatically at your chosen pre-set voltages. An example......... When the Solar Battery voltage drops to say 12.0 volts, it will automatically switch to Mains (Grid) A/C Power thus protecting your LifePo4 Batteries from being completely drained and/or or the LifePo4 Battery BMS shutting down the power. Then when the Solar Panels have recharged the Batteries up to say 13.0 volts, it will automatically switch back to Solar Power…….. Easy! This makes it an ideal ATS for a small Solar Panel (PV) System, as it reduces the risk of your LifePo4 storage batteries from being completely discharged. Negative and notable points...... Despite this ATS being rated at 1100 watts, it does have voltage and power (watts/amps) limitations depending on your specific setup. In my 12v Parallel PV System, the recommended limit is 600 watts/50 amps. The intuitive design of this ATS does have some notable flaws, some of which could cause major safety issues…… The internal relays are mechanical and there are no apparent safeguards/protective circuitry should a relay or a power source fail (which of course they can). The terminal block and screws on the front on the ATS is not covered or protected, they are therefore live and some will have 230 volts available for little fingers or metal tools to touch. In my humble opinion (and this is what I ended up doing), the safest way to use this ATS is to have the secondary power source as a backup LifePo4 Battery or Batteries, rather than the mains grid. Given the lack of safety circuits as shown above, this will ‘reduce’ the risk of damaging your Inverter, any safety issues with the grid and/or the risk of fire. ## 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.nz/products/115985362-dual-power-controller-50a-11000-watt-automatic-transfer-switch-off](https://www.desertcart.nz/products/115985362-dual-power-controller-50a-11000-watt-automatic-transfer-switch-off) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-03*
