We are running a 3 phase hybrid system using a cerbo GX, 3 x 15 kva inverters and its backed up by a 45kva generator. We have an intermittent fault of the generator not detected at AC.
We have checked the relays are all set up correctly with open and closed messages, we have ensured the battery charger is connected and the addtional water jacket heater on the generator is connecred to aid start up function on the unit in colder temperstures. We have changed the cranking permitres in the control panel it attempts 3 times before shut down.
The hybrid units are in remote areas where the auto function is vital however its letting us down. When we send an engineer to manual intervein and test the system it will work, once left fot a few hours it just stops seeing the generator upon request. The invertors see the message directly from the pylontec batteries can bus system. We have the soc and the voltage level set in the low level perimeters.
It seems to me we have a communication error for when the batteries are depleted and it requests help from the generator, the message is sent however the link is broken remotely becuase it just fails to start.
Can you help or offer any advise?
