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.

Works 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.

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.

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.

I run my computer equipment via an Inverter run from Solar/Battery and bought this to automatically switch to mains power when my Battery runs low. It has been flawless. I never notice when it switches to/from the Inverter. The only extra that I would like is remote access to see the state. Not a biggie as the rest of my kit is Victron and so I can see the Battery and Inverter status via the Victron Connect app/VRM.

Arrived on time. Did not auto transfer. Returned to Amazon.

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

I got this to allo me to allow devices to work all the time on my small 100W solar panel. It automatically switches the 110V power between the converter and the grid based on the power available in the battery. Works great!

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

Şebeke elektriği ve akü arasında çok hızlı geçiş yapıyor. Elektrik kesintisini hissetmiyorsun. Tavsiye ederim. Tşk Amazon

Questo articolo era proprio quello che mi serviva per completare il mio piccolo impianto fotovoltaico. Funziona davvero bene ,semplicissimo da impostare e da gollegare . Le istruzione sono davvero ben dettagliate Finalmente non si hanno più stacchi di corrente ,perchè non appena la batteria si ricarica il dual power ritorna automaticamente al fotovoltaico.Basta accendere l'inverter la mattina e spegnerlo la sera così non devi più preoccuaprti se la batteria va sotto tensione. Io ho prefertio impostare la tensione di scarica a 12 volt e la massima a 12.5 in questo modo la batteria agm durerà molto più tempo,senza scaricarla oltre il 50%. Consiglio vivamente l'acquisto di questo prodoto. Spedizione prime ovviamente puntale e veloce
