Question Flexboss in offgrid setting with generator

Yes, — but only if the device actually supports that function. If the manual mentions dry contacts but doesn’t explain how to program them, it’s possible the feature is there but not enabled by default. I’d suggest checking any advanced settings.

My understand (and I could be wrong) is that you need a grid boss paired with the Flexboss to get gen functionality.

As Joel mentioned, you would need the GridBoss in order to use a generator, as the FlexBoss was designed to work alongside the GridBoss. The FlexBoss itself does not have a dedicated generator input.

well what are the dry contacts for.  Please do not get hung up on the generator.  How about an external fan at certain voltages or while charging?

I would just like to know if those dry contacts are usable or not.

@srafter2 
NO1 and NC1 will work with a generator only when the Micro Grid setting enabled. 

Microgrid is enabled. But the only action in the app that changes the contacts state is the “ generator exercise “ button. What other parameters are available or necessary to change the state of the dry contacts?

You would need to go to the working mode tab in the settings and set the Micro-Grid parameters

@srafter2 hey, I would like to know if by using the contacts and setting the parameters in the settings you got the generator 2 wire system to work? Thanks

I have not been able to figure out how to control the contacts.

EG4 Eric, you sent a pic of the microgrid settings, however I do not have that bulletpoint in the app or the web application.

The only thin g I can do is enable microgrid. There are no parameters to set.

Any info would be appreciated

You can go to Working Mode and scroll down to Gen Function. These parameters are only applicable when Micro-Grid is enabled.

@srafter2 I was able to set generator dry contact parameters in the android app for my Flexboss18. No microgrid options appear for me either. I can set the SOC percentage to toggle on the dry contact and the percentage to turn it off in the app generator settings.

Expand the "Charge Setting - Generator" drop down and there are options to adjust when the dry contact becomes active. 

I have mine setup to turn on a 220v contactor that turns a 30 amp receptacle on or off. The receptacle provides power to my Ecoworthy 60 amp 48v charger then when powered on just goes into AUTO and charges the batteries. When the SOC reaches the setpoint I chose, it kills power to the charger outlet and the charger. The contactor I am using from Amazon is shown here.
