Hi. I want to add solar PV inverter power monitoring to my CCGX display. I have a Multiplus 3000/24. I've checked the serial number and I should be able to use the Victron AC current sensor. I'm already using the temperature compensation inputs for temperature compensation so was going to plug into the aux in.
My question: Does anybody know what the current sensor outputs ? Is it a voltage (eg 0-5V) relative to measure current with limits set up by the dip switches, or a 4-20ma current similar to water sensors etc or something else.
The reason I ask is that my whole system has been built from recycled batteries, used inverters etc. The only thing I had to buy new was the CCGX because I'm short on home time at the moment, I work away a lot and didn't have time to learn raspberry pi (YET!) . There are several alternative current sensors available which are much cheaper than the Victron unit. I realise that Victron need to make a decent profit on the accessories and where I work we exclusively buy new Victron equipment to the sum of several tens of thousands of pounds worth which I install so I do feel I support them best I can....but I'm on a tight budget here. This is just my home project to try and save the planet! :-)
Any help or information would be handy. Thanks
