Turn off MPPT from Victron app.

[beebobby]

2022 21C, one panel, 2 lith batts. When I was winterizing, I think I turned the MPPT function off from the app, now I don't remember where in the app that was. Was it the MPPT portion or the BMV portion?

MPPT portion.

However, at a minimum I still want a manual, physical, shut off, either a breaker on the hot wire, or a double breaker to be 100% sure contact has been interrupted.

Enjoy,

Perry

Easy and cheap to put a dipole dc cut off switch just before the Mppt controller.

Her is what I used

I have installed a disconnect switch between the pv and MPPT. What I'm asking is where the setting in the app is that allows you to enable and disable the pv . I found it once before I put in the breaker.

Under settings charger enabled . Click on the gear icon

MPPT-settings-battery-Charger Enabled ?

Correct

Got it. Thanks to all. Another quick question. I installed the temp probe. Should I turn on Temperature Compensation?

Lead acid yes
Lithium no

Thanks again for all the info. It was much less technical with the Casita we had before, but I love the new stuff. As long as I have some experts on, is there any way to make the Victron app display F instead of C? The BMV display inside shows F.

You change that setting in Victron Connect

Found it ! Thanks to oldwave. Love this forum.

I want to install a switch to disable charging my Li batteries while it’s in storage with a switch between the pv & MPPT. Do you know if it’s ok to leave the MPPT connected to the batteries or do I need a second switch?

You would typically have a "battery disconnect switch" that would do the trick while your trailer is in storage.

I installed a dipole breaker between the PV & MPPT. I also installed a breaker between the batteries and the MPPT. My understanding is that its not a good idea to keep the MPPT connected to the batteries if the PV is disconnected some folks may have other opinions. Having both makes it really easy to work on the electrical system. I installed a Blue Sea 30A circuit breaker:

There are less expensive versions of this on Amazon. I personally just feel more confident in the quality of Blue Sea.

In the standard Escape configuration the solar controller output goes directly to the battery (through a thermal auto reset breaker), not to the disconnect switch. Opening the disconnect switch does not disconnect the solar controller from the batteries.

There is no need to add a switch on the output of the solar controller although I have installed a marine breaker that can be used as one in mine. I do feel a switch/fuse/circuit breaker between the panels & the solar controller is useful since the input to the solar controller should be disconnected if the batteries are removed (or disconnected).

Do you not have this setting?

I have not gone through all of the documentation on the electrical systems on our new E23Q, but this photo would suggest that Escape has installed cutoffs for both solar and DC.

Interesting. Looks like ETI made some improvements in their solar setups. Where does the DC Disconnect go, or should I ask what does it disconnect DC from?

One of the first questions I asked myself. Gonna read up on the switches on the docs that I have not gotten to yet.
