Victron Phoenix remote control with SmartBatteryProtect

[lydart]

I would like to use my SBP65 to switch off my inverter via the remote switch. I've used the wiring diagram from the SBP manual but it won't switch off the inverter when low voltage is triggered by the SBP. All the other circuits are automatically switched off by the SBP.

Any ideas?

Has your inverter got a ve-direct port?,have you got a pic of the set up

 

[lydart]

Yes it has a ve-direct port. It's a 12/375. I've followed the wiring instructions on both the inverter and sbp manuals to use the remote control instead of the ve-direct port. The inverter is connected directly to the battery bank by anderson connectors because there is no room left under the seats! The left hand terminal of the remote on the inverter is connected to the output side of the sbp.

Got a pic of the invter terminals?

 

[lydart]

I'll take a pic tomorrow.

 

[Lowlec]

Have you removed the factory link from the 2 pole remote connector on the inverter,before installing the sbp cable to the left side terminal?

 

[lydart]

Yes I removed the link.

 

[lydart]

Here is the inverter. It does not work if the green terminal block is removed. So it works with the link in place or left terminal connected to the sbp output but doesn't switch off when sbp is active.

[Dellmassive]

so we need to look at the SBP side of things

[Dellmassive]

what is the settings on the SBP ?

 

[Dellmassive]

 

[Dellmassive]

are you sure that this black wire on the LHS of the inverter remote block is connected to the SBP OUTPUT side.




can you use a volt meter to measure the voltage at this terminal when the SPB is

on..? (should be +12v)

an

off ?? (should be no volts)


i think the problem is here at this point.

 

[lydart]

Yes the black wire is connected to the output side of the sbp. I haven't decided on the final settings and was just testing the sbp and the inverter remote control.

I'll check the voltages.

 

[lydart]

On is 13.23v

Off is 1.643v

Error code E3 on sbp. All other circuits, fridge etc are automatically disconnected.

 

[Dellmassive]

So we are saying the 1.6v is enough to startup the inverter?

Possible back drain from the rest of the kit.

I'm thinking first of all email Victron technical and ask them..... they are very good. / helpful.

In the meantime in thinking use a high value resistor (1k - 1M ohm) across that line and ground at the inverter input terminal as a pull down....... its sounda like the similar thing that keeps some LED lights on very dim.

Either that or fit a relay before the input to shunt the connection on/off mechanicaly ...

 

[lydart]

Thanks for your help. I was already thinking about a resistor but I will contact Victron technical. I've ordered a clamp meter which is arriving today. I'll try and find the source of a possible back drain tomorrow. I'll post back when I find a solution.

Did you get any response from Victron? I am about to contact them with the exact same scenario, and I found others online. It appears the BP has a residual 1.6v when turned off on all devices.

Make sure all devices are full up to date regards to firmware

I don't have the smart battery protect, does it have updatable firmware? I assume I would need to purchase a VE direct cable for the inverter to do this?
