Hi,
I'm trying to dump excess solar energy to my hot-water tank. I'm all setup, except the "MPPT Control" LED display is not clicking it's internal relay when the virtual load is set to "ON" I can see it on the screen, but it's not triggering it.
What am I doing wrong?
Thanks everyone :)

Hi Jonny ! I have been considering using excess solar for heating, and have read alittle about the relay function....but dont quite get it.
I have an Easysolar 24/3000 with Bluesolar 150/70 built in. I currently have float at 28,55 volt (and absorption at 28,65).
I have 10Kw of recycled Lithium Ion (from Mitsubishi Miev) and 2 strings of 900W panels.
Question:
I want to switch on electricity to ovens when the battery voltage i above 28,55 volts.
Or should I have the voltage level different with regards to bulk/float/absorpton -levels?
How do I do this?
Eric
Hi @JonnyT,
It is not clear to mean what you mean. Do you mean you want to use the relay in the MPPT control : https://www.victronenergy.com/panel-systems-remote-monitoring/mppt-control
The relay in this product is not supported. You should use a BMV or a Smart MPPT with relay.

Thanks Martijn,
Yes, I was hoping to use the relay that's built into the MPPT control unit you linked to. As the relay exists, but it's apparently limited (intentionally to sell other units I'm guessing) within firmware.
I have since had to swap the BlueSolar with a SmartSolar as per your second suggestion :(
