I love that I can program the low/high voltages cutoff/resume to trigger the switching.
This ATS puts my inverter on hold while switching to grid when batteries are low, and resume to inverter mode by default. Since I’m not feeding the grid, I do not have to worry about permits nor frying anyone should its power fails.
My system is very minimal, using only a 2p4S UPS lead acid batteries each about 18Ah. So at 48VDC I get 32Ah.
However, when my 2000W inverter kicks in each mornings, it maintains the batteries charged, while powering 2 fridges rated at 6.5A and 7.1A, some pond pumps at 2A on a timer, and a ceiling fan 2.5A also on a timer. Since these are surge currents, most of the time my inverter is really idling around 3A. So my electricity usage is cut by half because these main loads are working 24/7. This simple setup saves me about 2.5KW each day. Actually I could have put all the loads on a timer and not buy this ATS, but the fridges must stay on at all time. Moreover, in the future I plan to drive some heavier loads like charging some EVs and I will then get some substantial Lithium battery banks. When I do, these programmable voltage cutoffs will come handy. So I kept this ATS… But if you don’t need this feature along with the 12,24,48V auto recognition then save 2/3 the cost. Buy instead a cheaper reliable ATS and that should work as well.

Good product. Easy to set up and use. My only complaint is, I once switched off my inverter while my batteries charged so when they came up to switch over voltage it will still switch from main to inverter even if there is no power coming from it. So my freezer went off. So it doesn’t know if your inverter is on or off and will still switch.

I live in northern Arizona and have had a hybrid solar setup for 3 years now. I have a large 12v battery bank with 2 separate inverters as well as grid power. I have been trying to rely less on the public power company.
My system works like a dream until last winter when I was away. We had almost no sun while I was gone and my batteries got down to a really low level. The batteries have never been the same – not as efficient.
I stumbled upon this product and almost couldn’t believe it. It appeared to be just the thing for my solar setup. I hooked it up. Like another purchaser, hooked my grid ground to inverter ground to ac output ground. I hooked it up to one of my inverters that runs my huge refrigerator w/icemaker and deep freezer. I set the lower switching voltage to 12.2 and the upper to 14.4 (I want the batteries to charge up really well in the morning before it switches the fridge and freezer back to the batteries)
THIS THING REALLY WORKED! It switched the power from inverters to the grid so fast that the fridge didn’t even notice. Usually the fridge’s computer buttons light up and beep when there is a interruption to power. Like I said, it kept humming along like nothing happened.
I ordered a second one to switch my computers, DVR, flatscreen TV, etc. I will be setting the switching voltages for that inverter so that they switch back to grid only when the batteries get much lower.
I am a happy customer, and would recommend this to anyone who has tried on their own to get the best of both worlds between solar and grid power.

I bought this Automatic transfer switch for my new off grid 4000W solar system. It is amazing and smart. The followings are the points I have summarized after using it for some time.
A. The trouble with me has disappeared because of this device. As we all know, grid tie solar system is very expensive, and off grid system stop charging battries for a period of time in rainy day which will affect my experience. This ATS can solve this problem perfectly. When batteries run down it will automatically switch to public power (1. protect the battery pack, 2 The power at house won’t be cut off). When battery pack has been charged to the point set up, house will be rechanged from the battery-inverter, so I can save lots of costs in electricity bill every month and only need to spend a small amount of money on an off-grid solar system.
B. This product comes with no cables, so you still need 1. Male cord , used to plug into a socket of a public electricity grid. 2. Male cord, used to connect to your inverter socket, 3. Female cord, used to connect to your load. 4. Wires, used to connected to the battery pack, not need to be very thick, it is just used to monitor the battery voltage. The wire from battery to inverter shall be additionally connected. For those of us in the United States, the black line to the L, white line to N. (I suggest you to employ a professional electrician to cover all of wiring work if you don’t have relevant knowledge of electrical wiring)
C.Pls DO NOT get it wrong when you set the Cut-off voltage and Recovery voltage. As seller reminded, Cut-off voltage must be lower than Recovery voltage.
I’d love to DIY and try new appliances and products, I will keep an eye on this seller and contibue buying products from them as I think their products and ideas are very good and interesting! When I am free I will share my use feeling and discuss it with you guys.
Regarding the dual power transfer controller ,I would really recommend it to anyone who has a (5K Watt or less) solar system. 5 stars but how I wish I could give them more!

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.

Pros: Does exactly as specified: switches to grid when below a user specified voltage. Allows me to avoid low-voltage inverter shutdowns during appliance start-up surges and wear on batteries by avoiding use of them when under 75% charge.
Cons: not the best user manual, rather scary when dealing with potentially ungrounded 110v+ power and the manual warns of “smoldering fire” if anything goes wrong.
Includes virtually no info about grounding the AC output line from the transfer switch. Also does not make it clear what powers the LCD, causing me to panic when it would not start the LCD off battery power alone fearing an ungrounded defective unit may short my home’s AC lines. Turns out it apparently needs a grid AC connection to power up the LCD and program the unit at all.
I grounded the battery negative to earth via an outside stake and the AC plug ground to the battery negative. My ground detecting power strip claims it is grounded and no fires yet. Phew!

Ho installato il prodotto per avere la garanzia di una corretta alimentazione anche in presenza di un basso livello di carica della batteria o di guasto della stessa. Ho avuto modo di testarlo ed il funzionamento è quello atteso; appena la corrente erogata dalla batteria (che alimenta un inverter) scende al livello impostato (es. 12 volt) il sistema passa alla rete domestica; quando il livello della batteria viene ripristinato il sistema ritorna all’inverter. Pienamente soddisfatto.
