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).

Application: Off-grid solar or wind system Review: Vital, perfect control unit for home solar projects. - If you want to build your own solar powered project with battery backup, then this is an essential piece of kit. It's even a vital bit of kit, because it does it's job based on a simple principle of storage battery voltage sensing. My small project has 620w of solar panels, a 300Ahr LFP battery, and a 2kw pure sine wave inverter. This powers two deep freezers which use (when both are on) no more than 240w, barely 10% of the inverter capacity. The switch limits on this kit can be customised, and I have set mine to switch back to grid when my battery reduces to 12.5v, and revert to the inverter once the battery voltage increases past 13.1v. The switch between the two power sources is so seamless and quick that my freezers don't stop running if it happens while they're running. So far I've proved to myself that a fully charged battery can easily run my freezers, now it's a question of keeping the battery charged well enough. Ok with the UK weather I might need more panels, but here's the thing;- with this device you don't have to worry about your battery running low because you have the peace of mind knowing that if it does then you have the grid as backup. This is my second device, when my previous item went faulty after over two years. I have to hand it to the seller here (MOES) who gave me a good discount on my replacement.

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.at/products/115985362-moes-50a-dual-power-controller-automatic-transfer-switch-ats-11000w](https://www.desertcart.at/products/115985362-moes-50a-dual-power-controller-automatic-transfer-switch-ats-11000w) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-20*
