- Turning Off Your Fronius Inverter | Know Your Solar | Episode 8
In this episode of "Know Your Solar", Mark shows you the correct way to turn off your Fronius Inverter. There are plenty of reasons you may need to turn off your solar, perhaps you're having your panels cleaned, maybe a new TV antenna is being installed or your gutters cleaned? Well, regardless of what's work is happening, it's important you know how to turn off your solar properly. Watch this quick video so you can learn how to avoid doing any costly damage to the inverter. That way you can rest easy knowing you're doing it correctly and ensuring your inverter survives like it's meant to.

Fantastic. So clear and succinct. The images showing what to turn are very reassuring. Thank you 🙏
Thanks!
Actually, there is a "pause" mode in fronius menu. This will temporarily stop production to click DC switch safely. And there is no need for AC switching at all.
There is a third switch, next to the inverter, 'Inverter AC Isolator'. Do you ignore this switch, or is it an alternative to turning off at the switchboard?
Good to know. Now I want to know how I do this when there is a battery also connected.
Even better, what work around will help me keep the battery full on a summers night when we have huge storms approaching and I might need to go on BACKUP POWER?
My Battery is usually at10% and cutoff by around 1am. That means I only have 10% of 19kwh for emergency backup.
So at 4pm when the battery is still above 90% and there are storms forecast, how can I safely disconnect or stop the battery from discharging too far?
PS, I know Fronius is going to provide a user activated "Storm mode" in the future but that is not here now.
Thanks Mark.
@@markcavanagh then to turn it back on say, at 3am , I just engage those breakers again yes?
@@markcavanagh I have a work around. I wanted to let you know so you can mention it if you wish.
I log into the inverter using the IP address and the customer credentials.
Then I on the left click on the menu option and select Energy Management and then Battery Management.
Then I create a time based rule for MAXIMUN DISCHARGE and set the limit as 1000W from 1pm to 6pm and a second rule limiting discharge from 8pm to 10pm to 100W.
This mean the battery is still around 80% at midnight and 20% at 5am, finally going flat just before it starts to charge again.
By shifting the battery discharge from early in the night to late in the night, I hope to have a fuller battery when if there is a blackout at say 4am.
I hope this makes sense.
Hi ! I just started looking at your videos. What would be the best solution if I have shade coming from left to right, optimizer, Enphase microinverters or Fronius ? Thank you !
Does turning off the DC on the Fronius, indeed isolate the inputs or does it turn off the electronics connected to the inputs only interrupting the current because of removing the load? (which would have the same effect as turning the AC inverter output off?)
Hi peter, I don’t fully understand your question, but if you turn off the dc when the inverter is running at full power, it’s opening an MC4 connector on a roof. It causes a significant DC arc on the contacts. It is designed to handle this, but only for a certain number of times. (If you switch it late in the afternoon, it will be fine.)
@@mcelectrical Thanks Mark, is turning the off the DC at the inverter indeed the same as disconnecting an MC4 connection or does the DC inverter switch turn off part of the electronics responsible for the load that the inverter puts on the panels? The first option would indeed encouraging that DC arcing that we should be so concerned with, the second option would avoid this as this is - from a DC input perspective - is the same as turning the AC output off. I guess it is more a question for e.g., the Fronius manufacturer as even different brands can decide how to implement this differently. Turning the DC inverter input switch off would allow one to work on the panels while the hybrid side of the inverter is still operational. It is a rather technical question with different answers for different manufacturers and the answer is not necessarily that important.
Hi I bought fronus inverter it trips when main off need to remove load to start it again my one battery is poor is this problem related to inverter battery solar or breakers?
I’m guessing you have a Byd. Either way, this should help explain why it is tripping. th-cam.com/video/lgwnzLvvaZI/w-d-xo.htmlsi=d_W85JjzgHm4p-0G
How do you set it up to switch over faster or not turn off? We have BYD battery so it should simply switch over use
Hmm, this is a real problem. I’d be interested to know who sold you this system and why they are not supporting your questions. I short, it’s about a 60 second changeover at the moment. That may get better
is this supporting unbalanced power loads? example: can this deliver 6kwh as follows: L1: 4kwh, L2: 1kwh, L3: 1kwh ?
Hi Bogdan, yes and no. Hopefully this link works, and it should answer your question www.mcelectrical.com.au/wp-content/uploads/2020/10/byd-blackout-sizing-guide-v5.x64370.png
Seems if wasn't junk it would have faster switch over and would chts its own power to itself 🤣
So every brown out and black out will damage them 🫣 should have gone Godwin it's 20 milliseconds... switching over....
Seems to me if it was junk it would have ignored regulations. Fronius plays by the rules. It’s a long game
