Ats

What would be ideal settings on a moes ats switch on a 48v system
Low and high
Thanks

Are you talking about low voltage cut out , to swap with ATS from off grid to on grid ?

What batteries chemistry are you using ?

Thanks for reply
4 12v 200ah sealed wired for 48v
Yes low cut off and return to battery

Don't use a Moe's. They're not safe.
They don't have any safety interlock. They can connect to both sources at the same time. This has fried people's inverters in the past.
It's not a true transfer switch. It's just a couple of relays in a box.

Lead acid, sealed lead acid (AGM/gel) or LiFePo4?

Sorry lead acid

Yes, the Moes is dangerous.

You got me thinking now
But why are they sold with the description that they will do the job

Because people will buy them.

Right after I saw Will's review I went out and bought one.
I've only seen a few complaints about fried inverters, I imagine if they are as dangerous as stated I'd had seen more with a few fires thrown in for good measure.

It's been operating for over 3 years now without problem.
I've got a 24v, 3500w dumb as a rock inverter. (Eco Worthy)
It took my system from a backup only, to a "grid assist" providing about 20% of my electric us

I've taken the cautions and warning on the forum as a reasonable heads up.
Someday when I can afford a good AIO the MOES will go into retirement
Until then the system's components stay in the garage

More than likely. The people who didn't listen to the warnings. Were too embarrassed to return.
You have been very lucky, so far.
When (not if) yours fails. Please join us in trying to save others.

Sorry lead acid

No probs at all ... it's just it's different for different batteries, good to be accurate.


really if you want them to last a long time, you shouldn't take them below 50% state of charge/SOC - which is roughly 11.6v

BUT voltage is a poor indicator of state of charge (SOC) , 11.6v won't be exactly 50% it could be a lower eg.40%

so it's best to get yourself a shunt that monitors amps in and out , and gives an accurate SOC like a victron smart shunt or Aili battery monitor... then you'd set the low volt cut off to the voltage the shunt reads @ 50%soc

again that's not perfect but its better

victron is more accurate but triple the price
