 For Off-grid systems, its strongly recommend to make sure there is a minimum of DC-Coupled PV (= MPPT Solar Charger) in the system. Ie. not only AC-Coupled PV. Also, minimum battery configuration, and factor 1.0 are always important to adhere to, and even more so in case of Off-grid systems. Both Cegasa and Victron will be reluctant or even refusing to give support to systems that are not sized according to the minimum battery configuration table.

 If the system is not operating correctly, go through these steps.

+=== Step 1. If the Inverter/Charger or GX device does not switch on ===
-As a safety precaution, the inverter/charger will not switch on if the [[venus-os:start|GX device]] is not on. If you are unable to start the system due to a total system blackout / battery shutdown due to low voltage, you may need to disconnect the VE.BUS connection cable between the inverter/charger and [[venus-os:start|GX device]].
+Low voltage and deeply discharged behaviour
-You can then start the inverter/charger from an external charge source such as a generator or grid connection. Once the inverter/charger has started, it should supply power to the DC terminals and this should start the [[venus-os:start|GX device]] and battery again. You will need to then reconnect the VE.Bus Communications cable back to the inverter/charger and [[venus-os:start|GX device]].
+When the grid is connected there are two software controls to sustain voltage. The Minimum SOC (while grid is connected) set in the GX device, and the sustain voltage (set in the ESS assistant).
-=== Step 1. Check that the battery is visible on the GX device list ===
+If the grid fails and no AC supply is available, in this deeply discharged state, and the battery has set the Discharge Current Limit (DCL) to 0A, then the inverter will turn off in a software off state.
-{{ :battery_compatibility:cegasa_gx.jpg?290 | }}
+The GX device will remain on, as there is still DC voltage provided by the batteries for a while.
+Note in this state an AC PV inverter will not produce any power, and will not start up, as it requires the inverter to create the sine wave to synchronise.
+If the AC grid or generator, or DC MPPT is connected, then the battery will begin to charge and then the inverter will start itself again automatically, also resuming charge from an AC PV inverter.
+If instead the battery becomes completely discharged the battery will further protect itself by not just sending the 0A discharge limit, but also disconnecting DC voltage from the battery terminals (via internal MOSFETS).  As there is no DC voltage available on the terminals any more the GX device will also shut down, and the inverter will also then be hard off (not just software off).
+If you then reconnect a DC charge source, or AC input supply (grid or generator), after approximately 2 minutes the inverter will start up again, power the DC bus, powering up the GX device, and then powering up the battery, and the system will recover.
+=== Step 2. Check that the battery is visible on the GX device list ===
+{{ :battery_compatibility:cegasa_gx.jpg?400 | }}
