Good USB Hub for CCGX with low power draw or Relay shutoff for inverter?

I use a CCGX, BMV-702, 3 MPPT's, and 1 USB wifi dongle.

Since there are only 2 VE direct and 2 usb ports, I need a usb hub to get my 5th connection point.

Currently, I have a crappy AC powered usb hub on the old phoenix inverter (That doesn't have ve direct port, Insert angry face) and the inverter is in ECO mode.

The USB hub is the only AC load on my boat, and I only really need it to send the wifi to check the system.

Is it possible to use the relay on CCGX or BMV to turn off phoenix inverter using it's remote port at night, when I don't need to check the wifi?

Or should I just find a low powered USB hub that runs on DC? (Does anyone have any recommendations?)

Every night, my BMV says 100% but the AC inverter is powering the USB hub through the night, and it uses about 2% of the bank and 96 watts. Is this slowly killing my batteries? Should I not be worried about this daily 2% discharge?



Thanks,


Mark

The Digitus 4 port spider USB hub is quite good. It uses a SMSC chipset which is one of my personal favourite USB hub chipsets.
The Digitus is powerd by the upstream USB port and can be powered by an external power source if the upstream USB power is insufficient.
