Even if you use CANbus between BMS and Victron, I strongly recommend to also use the Aux in1 and Aux in2 inputs start/stop charger and inverter. Just...

HiLeigh, I have no experience with this integrated Victron EasySolar-II GX unit, but looking at the documentation: The Victron EasySolar-II GX i...

Model "D" needs a minimum of 32 VDC to close (the relay will not close if the coil voltage is less than 32V). So if you power it with 48V, that shoul...

A quick search shows there are a few suppliers on AliExpress who have 48 to 24 Volt buck converters with a larger range of power Here is one example...

No significant difference for the TAO monitor if you power it with 12 or 24V. It uses a buck converter to take that voltage down to 5V, so it is quit...

With a larger resistance the current is lower and more time is needed to charge the input capacitors of the inverter - so 12 seconds with a 66 Ohm res...

Yes that should work. Very good idea to test charge curve with a momentary button to power the the inverter through the resistor. Do you have the...

The idea is to have a current a bit less than 2A when it starts charging the inverter input capacitor (the capacitor behaves like a short circuit when...

Hi Andre, I am afraid that will not work as the documentation for the REC precharge unit says: The pre-charge energizes the contactor coil throu...

Quote from molly on 05/03/2022, 10:46 am then i could leave out the bluesea 7700 relay in front of the multiplus and switch the charger and invert...

Hi Leigh, I do not have pre-made CANbus cables as each vendor has a different connector and also wiring to different pins. The most flexible and le...

@leighcaldwellbigpond-com Yes, the BMS can also remote control the MultiPlus charger and inverter independently. I do that on my installation with ...

Hi Andre, You did put a lot of thinking into your installation planning. There is a lot in there to absorb, but at a first level that should work. ...

You do not want to connect the backup battery more than a few seconds before the disconnection of the lithium battery. If you connect it too early i...

I am not sure I understand your concern about the Monitor consumption for a 560Ah battery @ 48V. The current draw of the Monitor is a bit less than 1...
