[RE-wrenches] In search of better generator start relay for Outback system

Fri Feb 9 18:50:29 PST 2024

I agree with Roy and Jay.  No failures since exclusively using the auto
cube relay triggered by any of the Outback relays in the inverter or charge
controllers. I'm having good luck
keeping a Magnum based system running remotely and on auto using an old
MX60 I had hanging around it for its aux 12v output relay to trigger the
the cube and starting a Generac EcoGen 14 k.  All I can see on Optics is
battery voltage and  temperature at the water pipes using the battery temp
sensor and generator hours from the AGS set ip as a DC Genset.  All I need
to know....  pipes won't freeze and the generator will start. (PS I can use
the temp sensor as I am not using the Outback for battery charging as not
recommended for LFP batteries.
If the generator needs 3 wire start, such as the Honda 6 or 7K propane
generator. I use the Atkinson Mini autostart module triggered by the cube
relay.  Only one failure an it was the Atkinson unit.
