The Grid Support was preset at 48.0V, it still wouldn't let me adjust the DISABLED and was not charging.

What does SUPPORT VOLTS mean, I read it as if it's below this value it would 'support' as in charge??

But I don't get this displayed, I get:

Grid Support DISABLED
Support Volts 54.4V

Can you drop the support volts down? At 54.4V it seems like it would rarely be on battery?

Some issue with battey bms comms overriding?

Thank you for your responses.

In the manual:

• Grid Support – Rosie uses grid AC for loads based on SOC % or Battery Voltage.
   o SOC%:
      ▪ Low SOC % - Rosie uses AC IN (grid) to charge batts and run loads.
      ▪ High SOC % - Rosie disables AC IN and uses batt bank to run loads.
   o Battery Voltage:
      ▪ LBX – Set to low Batt V setpoint.
      ▪ HBX – Set to high Batt V setpoint.

But I don't get this displayed, I get:

Grid Support DISABLED
Support Volts 54.4V

And even if the inverter is in Standby I still can not change the DISABLED

The Charger is turned on.

To put the inverter into Standby I got USER/SYSTEM_FUNCTIONS/INVERTER ON/OFF and set to OFF... correct?
I tried this but still could not change the GRID SUPPORT Setting.

As far as Grid Support, there is no 'enable' function.  There are 4 choices under grid support, rotate the knob to select SOC, Battery V (voltage), Breaker, or disable.  Depending on which option you choose, the other line selections below Grid Support become relevant.

Hi all,

I am trying to connect a generator to help charge the batteries on these dull days. This is an offgrid setup, Rosie, Barcelona, Evault Max Battery + Solar.

I have connected the genset and ran it up. The Rosie changed over to the Grid/Gen AC and runs the house AC but it is not charging the batteries. On the menu, if I go to GRID SUPPORT it is DISABLED. I can not enable it. It only stays in DISABLED and I think this is why it is not charging the batteries.

It has the latest software updates on all units.

Any ideas please?

I believe you have to place the Rosie in standby before you can adjust that setting.

Just to be sure, you need to have the charger turned on in the Rosie.  Inverter Config, AC Input, Charger ... select off or on.

You didn't got back far enough Vic...boB, with Robin his brother, was also Xantrex/Trace brains, and i think in the 1970's designed and built some of the best audio equipment. 
It was always my delight to get some response from boB on a simple question on the forum.  Attention from the Head Barber for little ol me.

Hi Jeff,  &  Larry,
IIRC,  boB,  a Member here,  who passed,  within the past year-ish, did measure this nominal current,  and did post it on this Forum,  but no time to look,  just now ...  sure do miss boB !!  He was a great guy,  who did much of the design work on the Classics (and the Outback MX-60 CC, IIRC).

My opinion on this current,  Vic
