So when the BMS reports 100% charge at what voltage is the battery, Is that voltage rising or falling at the time and what current was the battery taking when it reported 100%? When you discharged the battery did you discharge it until the BMS shutdown and did you then reset the coulomb/soc...

Added the 4 way hub to my system today, worked as intended. I'm glad I now have isolated inputs and outputs on the VE Direct bus, it always worried me that the DIY ones weren't isolated particularly as when the Raspberry Pi was switched off the VE Direct bus was attempting to power the USB...

The pinout is different too, its not one to one, gets the old grey matter going when your making up your own leads!!

Also bear in mind that the supplied JST connector on the 4 port Usb pcb is a different size to the JST connector used by Victron. Victron use 4 pin JST PH connectors whilst the PCB uses JST XH connectors.

I paid €37 including p&p. They were on back order for a long time 2 months maybe but it arrived this morning.

I dont think this has been mentioned before but for those looking to connect Victron kit to a RaspbPi this product has appeared on the market. Its a fully isolated 4 port hub for the VE direct ports. https://www.duppa.net/shop/isolated-4-port-usb-to-ttl-uart-ftdi/

What was the connections on the bench seat you took out? You may also be able to take it to a dealer and have them disable the second seat

I've been using Guimods since the beginning and I find them really useful more for the setting up of the pi, not sure why the shutdown because as has already been said how do you start it up again? You can aleady reboot remotely so whats the point. I also lost my A/D inputs on the last update...

Worth opening up the inverter and see if the earth pins on the outlet are connected. I would suspect that the earth pin of those two sockets are not connected to the earth of the inverter, I doubt they are connected to anything. Happy to be proved wrong. That statement is based on opening up 3...

I used those diodes as I thought people could relate to them and to be honest they are 69p on Amazon when in a pack of 10. But you are right if there is only a handful of leds then a lower value could be used

You could just use a couple of 10A solar blocking diodes, one in each feed to stop one battery feeding the other

TVs mainly they generally have a 3v and 5v rail, 3v & 5v regulators in the majority have either 15 or 16v maximum ratings and seeing as most always employ reverse protection diodes which drops another .7v for a silicon rectifier diode you can see my point. We were recently discussing the...

I guess thats one of the advantages of running Lithium, the 12v supply is always going to be limited to a max of 14.2V and with most series regulators now fitted to equipment having a max input voltage of 16v its not really a problem for me. The current shunt on my Bailey control panel is very...

The control looks really impressive but I cant help that think controlling the fridge via the freezer may have different characteristics when its loaded up. It would be good to see the graphs with a full freezer and part loaded fridge just using water perhaps, just to give it some load. I wonder...

My Lithium hasnt charged for 10 days down here in the midlands mainly due to low tempearture. Plenty of Sun although only getting around 14w and that was yesterday for the first time above 5C I'm not sure about small charge amounts, there are conflicting reports out there as to wether its pk or...

If you take 13A from a socket it will get warm, thats 3.1Kw across the contacts. If its too hot to touch then yes theres a problem

Dont attach it to the coil of a relay as when the power is removed you will get a much higher back emf voltage unless the relay has a diode across it. More importantly I looked up the spec for the 3.3v regulator on the W1209 pcb and its max voltage rating is 15v so it should be fine, if your...

Victron Connect runs on a Mac

If you have 12.6v on one side of the switch and not the other side then either you have connected the switch wrongly or the switch is defective. You cannot have 12.6v going into a switch that is turned on and nothing on the output, that just cant happen unless it is defective. The earths of the...

I asked the question about input voltage tolerances but got no definitive answer other than what is in the manual +/-70v. I did confirm that what ever is the first voltage listed is the voltage of the controlling electronics so in a 12-24-30A 12v is the internal voltage, 24-12-30A 24v would be...
