MOES Dual Power Controller 50A 11000 Watt Automatic Transfer Switch for Off Grid Solar Wind System ATS DC 12V 24V 48V AC 110V 220V Black

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.

easy to set values and change as needed.....clear instructions...a very good product....especialy at the price...just what i needed for my 600 anp 300 watt set up.....

Fantastic auto switch, switches from solar/battery to mains and back without affecting any of my devices plugged in, including pc, tv, router, voip or monitor. The only downside is that the scewheads are not covered after installation, leaving exposed mains power. Not an issue really if installed away from easy access. But a simple fold down flap or slide cover would have made this 5 stars.

Really happy with this . Our previous inverter was damaged by an electrical storm. We have a battery system for back up when the power goes off which happens quite often in Ghana. We were using one which didn't have a mains power facility. Adding this one has meant we now use solar power to charge the batteries but utilise the mains power at night or for heavy duty items like our pump. The settings took time to work out ie the high and low power to work efficiently and ensure the batteries still have enough power if there is a blackout but we got the balance right and now we are making good use of solar power for the first time.

Not straight forward to wire but once you get your head around it it's easy enough. But it's a fantastic device to save some cash on electric and save your batteries

Item is a must for solar installations works a treat. Easy to configure, I don't need to worry about my storage battery going flat. Auto switch over mains.

This item dead on first run With the LV switch set to 12.3v and the HV switch set to 14v the unit is switched to inverter with a battery voltage at 12v and will not switch to grid no matter what you do with the cut out and cut in settings. It was lucky I noticed this as it would have wrecked my £1000 battery bank by running it completely flat. Also it is not very smart as you can set it up to work but if you forget to switch your inverter on it will still switch to the inverter input even though the inverter is off thus leaving whatever appliances you need to run with no power. This is not a Smart device it is nothing more than a simple voltage controlled switch that will not check if there is voltage at the inputs. Now it has let me down I will not be replacing it, it will be returned for a refund and I will be building my own with all the safety interlocks in place. In my opinion this is a good idea that has not been very well thought through and is left open to far to many errors on the part of the unit itself and the operator. (Over Priced For What it Does)

Great product.

This do the job perfectly !!!

Packaging is good, when I unbox everything, it's fine, when I open the module, the relay is 12 volt DC 60 ampere, the specification is 50A load, in my opinion, the capacity of the relay can handle safely at 50 ampere, the jumper wire it looks high capacity conductor, at this moment, not yet testing for a real load.

No priority setting possible Useless if you want priority on external (grid) power Returned to supplier

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!
