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.
