VE.Direct non inverting remote on-off with 70/15 mppt

chenirl asked Jul 27, '23

My question is about amp drain on the SOLAR side when the remote is set to OFF

I will try to explain my setup:

System is a 48v main battery.

There are 2 75/15 on the solar side connected to the 48v.

On the battery side on mppt is connected to charge the 12v bus battery.

The other mppt chargers another 12v that is for lighting, Cerbo GX, BMS, and other DC stuff.

If the 48v battery has a low voltage or other condition, I want the BMS to toggle the 75/15 mppt's OFF.

Hopefully it makes sense.

Thanks!

Chen.

Oddly I got a mention from Alexandra, but it doesn't show here.

I am charging 2 independent 12v batterie, each on a dedicated MPPT, solar side of MPPT is connect to the main 48v battery.

I am thinking of using "VE.Direct non inverting remote on-off" cable to control MPPT in case of battery(48v) emergency.

not sure what will be the consumption from the solar side once turned off.
