Installing a rapid shut down switch on EG4 6000xp and Power pro battery.

- In this video I describe how to install a rapid shut down button. This will apply to battery models eg4 LL-v2 and above. Remember, the switch needs to operate on “normally open”. So whatever switch you choose needs to have that option.

Here’s a link to an Amazon switch that should work. Not sure of the quality though.

Somehow I missed that the 6000 XP had this option. thanks for the info, Gavin.
Sure thing.
If and when this goes code, you will more than likely have to put a "Rapid Shutdown Switch" next to the main Electrical service panel, along with a Solar "Emergency Cut Off" switch. I would probably run them in now and connect them in parallel at the 6000XP terminal. Best bet would be to get (2) "N/O" (Normally open) BIG RED button switches. I take it that the system will automatically shutdown the Solar prior to the batteries as this is the normal shutdown procedure for inverter shut down.
Very good points
Cool. Thanks for posting this!
Thanks for watching
I don't have one yet but I plan on putting one by my meter outside
(labeled for first responders) and one by the panels. I'll just wire them off the same set of wires since both are fairly close to each other.
Good plan!
Great info!
thx
Thanks, i wish i had this video 6 months ago when i installed mine to save a few back and forth calls with sig solar haha they made me runanother set from battery to switch which made everything not work so i left it like you show here :)
Yeah I expected it to be a little harder to honestly.
I think going forward most manufacturers will have to have something like this to shut the entire system down.
When I installed mine about 6 months ago like you did here, only the inverter shut down so they told me run a seperate 2 wire set to the battery port using 3 and 6 in the pinout but no matter how I connected both sets to the shutdown switch everything shutdown so I left the battery set disconnected, maybe a firmware update is needed?
I just installed the rapid shutdown switch. It does trip the wall mount battery breaker but not the inverter itself, is it supposed to actually shut off the inverter as well?
Maybe the firmware changed, only my load output breaker would trip when I hit the button. But that was a few months ago and I haven't tried since
@@tjmooney4181 I never checked that breaker to see if it had tripped. Will do that, thanks.
Another good video. Thanks! Have you installed an external RSD on your 18KPV? When I upgrade I'm absolutely going to have an external on the outside of the garage for emergency responders, as well as for me, of course. Once I've got it all set up I'm thinking about inviting our VFD out to take a look at it and see how it works, where it's located and labeled, etc. I mentioned this to one of them a while back and he was very receptive. As with a lot of rural volunteer departments, they haven't had a lot (or any) experience responding to a fire where solar is involved. It never hurts to support those folks and I do, but making them familiar with your personal setup could be a good thing.
I haven’t installed one yet on the 18kpv. But that’s my plan.
I like your plan. This is honestly one of those options you hope to never have to use. But you’ll be extremely grateful if you need to.
This seems like a really bad design oversight on the 6000XP. Safety switches are supposed to be normally closed. It should not be normally open. Think of this scenario, say the wire gets compromised over time and has a internal break. When there is a emergency and you push the button, the broken wire keeps the invertor from seeing the button press and the red button fails to do its job. If it was a NC switch (as it should be) when the wire gets compromised the discontinuity will act as a button press and trip the RSD circuit.
Yeah I was just talking about this with another person. There may be reasons that I’m not aware that it’s designed this way. Whether it’s hardware or
firmware related I’m not sure. 🤷🏼♂️
It does accomplish what’s needed. In fact, as far as I know the EG4 batteries are the only ones capable of this.
It's designed to fail open. It's supposed to be normally open
I wired mine backwards as well, the documentation is unclear, one part says NC is needed but your tests demonstrate NO is what is needed ... Thanks !
Yeah I just never really learned much about relays till this point. Between that and the chargeveter I gained some new knowledge. Either way I guess it was an easy fix.
Glad the video was helpful!
@@GavinStoneDIY NC for an Estop is probably more standard, makes sure the system shuts down safely if a wire breaks (using NO as the 6000XP does means you won't know a rat chewed your cable until you try a panic stop). EG4 just needs to sort their documentation ! That and the EG4 battery needs to be set as LUX inverter protocol despite there being an EG4 option on the menu ... fortunately tech support was helpful :)
Did you test the other 2 terminals on the switch? A lot of them one side is normally open the other side is normally closed.
Yeah it’s spring activated. Both sides are normally closed. But you’re correct, in most cases you’d have normally open normally closed on opposite sides.
I just installed the rapid shutdown switch. It does trip the wall mount battery breaker but not the inverter itself, is it supposed to actually shut off the inverter as well?
Do you have PV optimizers hooked up? If not, it could be your solar is still supplying power to the inverter.
@@GavinStoneDIY I am wondering the same thing. How would this one switch activate the rapid shut-down at the panel level, (Tigo models), or would that be a separate device?
@@stevenfontz9022 yes with tigo optimizers set up you’d have a complete disconnect.
Too bad they don’t do it like interlock on garage doors. They have a wire that has to be connected to operate the equipment and if any point in the wire chain, it breaks open it causes the interlock to disable operation. That way you could have a switch by the door and in the garage and any place else you wanted, but they all have to be normal closed like you bought.
Garage door uses other things in chain like safety beams and pressure pads but easier to run a single wire unlike the other comment here about needing to run a pair of wires from multiple switch locations in the future
Yeah that’s true. And if the line is ever broken the relay is activated.
