Synopsis
CL-350 pilot crew reported several abnormal electrical CAS messages after takeoff. The pilots diverted and landed overweight.
Narrative
During climb out of ZZZ to scheduled ZZZ1 crew noticed electrical flickering and anomalies. Our initial response is to level the climb and troubleshoot. We initially monitored the situation which was intermittent; and led us to a 'Unexpected Electrical Indications Checklist'. This Checklist was completed per SOP and the decision was made to continue monitoring electrical indications and system as it seemed the issue had self corrected. Momentarily after as we continued our climb to higher the issue continued; and we were alerted with multiple and varying EICAS messages regarding the electrical system. These notifications included L (R) BATT OFF; L (R) GEN OFF; Electrical fault. The crew immediately decided the issue was true and decided to divert to ZZZ2. During descent more EICAS alerted us with messages: R GEN FAIL; L GEN FAIL; APU GEN FAIL; L BATT FAIL; R BATT FAIL. We acknowledged these and continued our descent into ZZZ2. The crew acknowledged our fuel load which would require us to land overweight (roughly 2000 lbs). We accepted this given the alternative of total electrical loss. The rest of the approach phase; landing phase went per SOP and crew and it's passenger made it into the ramp safely.Cause: Electrical wiring; faults; etc.Suggestions: Maintenance
Second reporter narrative
After departing ZZZ; we began a turn to the East to join our assigned route to ZZZ1. In the climb; after we shut off the APU; we noticed several white Crew Alert System (CAS) messages stating that our left and right batteries were off and both of our generators were off. I instructed the FO to get the QRH and we ran through the checklist for a potential intermittent electrical issue. The checklist explained that we should monitor the electrical system and land as soon as practical. With this in mind; we decided as a crew that it was not practical to continue the flight. We attempted the start the APU. Fortunately; it started but the generator did not come on line. At this point; our white CAS messages turned to amber. We diverted immediately to ZZZ2 and attempted to get below the clouds. We were able to do this and proceeded to land; knowing that we would be overweight; but unsure of how much time we had before all of our instruments stopped working;Cause: Electrical wiring fault was the most likely cause of the event.Suggestions: Unsure; I am not a mechanic.
