Has anyone placed there rasberry pi insdie there invter to power it?

If so have few questions.

1. Where have you connected the pi to power.. did you connect it to battery terminal or did you find a 5v rail?

2. How have you secured it insdei the invter?

3. Does it invalidated your warrenty doing it his way?

Do you have any pictures of such.

As I have just had my install done but it is all outside and only way is to place the pi inside the invter and find a power rail / use battery rail to power it using a buck convter .

Many thanks for looking and your replies.

To get anything inside that inverter means breaking the seals and thus voiding the warranty. That's before you make any internal connections.

I think I see a WiFi dongle there. Almost certainly there's a port for an ethernet connection. So you have ways to connect the PI to the inverter via LAN.

If you need access to the PI then you have to crack the inverter open.

LAN is the win here.

Hi there is a wifi dongel yes... where would u say the lan port is? As I will be using S.A I need to connext the pi to the bms/can port.

Thanks

On the sunsynk you will not usually void/break the inverter warranty by opening the front access panel.
That is a user panel after all for connecting things.
That said, it is not a good idea to put the rpi inside the inverter. rather put it in an enclosure outside the inverter.

The sunsynk itself does not have a lan port, there are some versions of the dongle that have a lan port on them.
In the inverter there are rs485 ports that you can use to connect rpi and or other monitoring devices.

Think that is what I will have to do, is encase the pi in a ip rated box.

Only other question is where can I pull power from the invter to power the pi, as I have no power sockets out side.

Many thanks

SA has a power connection which you can connect to the battery.

Yes I have something similar to that a buck convter.

So does it connext to where the battery connects to in the invter or to the battery itself?

whichever side is easiest for you to reach :)
The terminals inside the inverter are a tiny bit more tricky to use.

Just make sure it is rated for 60v else you gonna fry it. And put at least a 5 amp inline fuse on the line between the battery and the converter :)

The buck convyer is 10V - 60V

So what would be best way to power the pi.

As u can tell I'm very new only had it installed and don't want to void warrenry or make it go bang.. and unsure where to locate a power source to power up the pi.

Just now, Bobster. said:

Have your electrician install a socket in a suitable protective enclosure.

Unfortunately that is not possible it would be an ideal solution but can't

That should be fine then :)

Installing a monitoring device should not have any effect on the warranty of the inverter. As for the warranty of the installation, you would need to make sure with your installer that they are ok with you adding in a monitor.
Should not be a problem as you will not be changing the way the system was installed. But check anyway just to be sure :)

Il drop them an email.

Now it's just to work out where to pull power from.

I appreciate you answering my questions thanks so much.

The sunsynk battery has a proprietary cable connection so your best bet would be at the battery terminals in the inverter behind the user panel.

Not sure of your model, but my 12kW Sunsynk inverter has a 12V connection (Pins 11 and 12) that should be just what you need - just confirm in your user/installation manual...

See screenshot from my manual below. Hope this helps 🙂

Actually I have never thought of checking the other terminals for output voltage.
I have 5.5k sunsynk similar to the @WelshDragon80 image.
I am off to find my multi-meter and go check :)

The invter I have is the Sunsynk 7kW ECCO Hybrid

Inverter I will have to go down load the manual and see if there is such on mine as that be so much easier

Impossible to connect any wiring if the service panel is not opened . No seal to monitor for warranty. AFAIK all inverters you have to open something in order to connect wiring

Doesn't look like mine does

Yes the 7k eco is an upgraded 5k, so has mostly the same configuration of terminals.
Just tested the terminals on mine and do not find any 12v output.

That does suck as could done it my self, as the wife does not want me or trust me more like to connect it to the battery terminals inside the invter 😅😅

alligator clips come to mind 🤣🤪

A friend did suggest that but I'd rather screw them on so I know nice and tight... I'd just have to see if any of my electrical friends will do it for me.

So come to the conclusion put the pi in a ip rated outdoor box next to the invyer and run some conduit to from said box to invter to protect from the rain and weather.

Would the pi be OK in a ip rated box, as I have the pi in a case with fan.. it would run too hot?
