Results for "ATS"

The automatic transfer switch on my 1999 American Eagle detects shore power and onboard diesel genset fine, but won't recognize my external portable generator — can I fix this for under $50? The generator runs fine and produces power, but the transfer switch doesn't trigger to use it.

What causes this issue and what are my options to get the ATS to work with an external generator? …more

Every time I flip the breaker, my 21-year-old coach's automatic transfer switch stays completely dead and I'm stuck with zero AC power. My Automated Engineering Corp ATS (model M10040A with M10041 display) is showing no AC on the LED readout even though shore power is definitely good.

I popped the cover off and confirmed power is getting TO the shore power terminals, but nothing's coming OUT to feed the AC system. Even manually pushed the contacts in and they stayed, but still no juice on the output side. Generator won't make it switch over either - it's like the whole transfer function is dead.

This thing has to be repairable right? Or am I looking at replacing the whole ATS unit? Really hoping someone has dealt with this before because losing AC in an RV is no joke! …more

Noticed my Grand Design's warranty paperwork doesn't mention inverter installations — would installing a 2000W inverter void my coverage completely? except my dream apparently involves wanting to run actual appliances without firing up the generator at 6 AM and becoming "that neighbor" at the campground! 😅

My TT came with the prewired inverter loop (thank goodness, because my electrical skills peak at changing light bulbs), and I know it's wired with 10/2 Romex that can handle up to 2000 watts. Now I'm drowning in inverter options and getting analysis paralysis.

I'm looking for recommendations on the best 2000W pure sine wave inverters that'll play nice with my Grand Design's setup. Also completely confused about whether to go with an internal ATS for simplicity or bite the bullet and install an external transfer switch. Help a fellow glamper out - what are the top models you'd recommend, and what's the real difference between internal vs external switching options? …more

Wondering if anyone else has dealt with a rental RV where the Firefly batteries and Victron system are constantly throwing conflicts I've never seen before. I have a 2020 Discovery LXE 40M that I've equipped with a complete Victron system - two Multiplus II inverters, Cerbo GX, and SOK lithium batteries. The problem is my coach's existing Firefly system is creating constant conflicts with the Victron equipment.

The AC units keep getting "shed" by Firefly, I'm getting random low voltage warnings even when my batteries are full, and my Auto Gen Start has completely stopped working. I've heard this might be related to waveform differences between the systems, but I'm not sure what that means or how to fix it.

I've seen some mentions of using dual transfer switches to isolate the systems, but I have no idea how that would work or if it would solve my Auto Gen Start issues. Has anyone actually resolved this Firefly-Victron nightmare? I really don't want to rip out thousands of dollars worth of equipment, but I need my RV systems to work properly! …more
