Hola Amigos,
I am looking for a way to have auto start/stop capabilities with a Flexboss 21 and my 2 eg4 14.3 kw wallmount batts. The house is Off grid and will have a propane Kohler 14kw generator . Is there a way for my flexboss 21 and generator to communicate to charge my batteries as needed without having to purchase a Gridboss.
Just to clarify ; completely off-grid home, approx 14kw of panels/ flexboss 21 / 2- eg4 14.3 wall batteries/Kohler 14kw propane generator
thanks

The FlexBoss21 is designed to work specifically with the GridBoss and does not include an input for a generator. To have communication between a generator and an inverter, a GridBoss is required. While you can charge the batteries without a GridBoss by using a chargeverter, keep in mind that this setup will not support automatic generator start/stop functionality.

Actually the Chargeverter-GC does a;;ow for communication with a battery pack and SOC/Volt setpoints for generator start.
However there are dry contacts on the flexboss . I just have not figured out where they go?
Anybody know?
