The LED's on L1 are as follows: (system operating well, no functional issues)
Inverter on = GREEN ON. All other 3 ( Overload, Low batt, Temp) are RED solid.
All cabling checked, firmware updated. System has Pylontech batteries.

By operating well, what do you mean? the correct voltage is there? It inverts if mains is cut off, your three phase devices have no issues? It reconnects to grid? It can handle the full load while inverting?
You need a GX. Do you have one?
How is it connected?
We will need more information.
Hi Alexandra, There is a a CerboGX. This offgrid system is still being commissioned but the installer indicates early commissioning and testing steps show the systems works well (ie supplies loads, 3phase output operates, AC coupled solar Fronius Symo Advance 20, Pylon batts ), apart from the LED's on L1 Multi. No generator at site yet so AC in has not been tested. Before the install, the L1 unit appeared to be dead on arrival as there were no LEDs illuminated (L2 and L3 LEDs came on) but its was found that L1 was indeed ON and operational. The installer has confirmed that during the fault finding, during power up, the LEDs on L1 will either be ALL off, or as per the description above.
Photo of L1 below when the LEDs are illuminated solid, not flashing. Sometimes these are all OFF. Installer is setting up router nxt week so I can do more trouble shooting. @Guy Stewart (Victron Community Manager)
Look forward to thoughts. David. DPA (Victron Distributor)
Extra details from installer - if this helps
- Out of the box, as a single unit, when switched on, NO LEDs, but 230v on output terminals. No comms cables connected
- On advice from DPA, removed cover to check lead to LEDS is connected ..... OK
- Unit connected to other units to create 3 phase system
- This unit is the MASTER (L1) unit
- NOT CONFIGURED, turn all units ON, LEDS on L2 & L3 flashing, as expected as they are not configured, still nothing L1
- MASTER L1 configured as pre usual and configuration transfered to L2 & L3 as expected
- NO LEDS on L1, LED "Inverter" on L2 & L3
- System produces 230v and 400v 3 phase ...
- Subsequent re-starts, the 2 bottom LEDS (RHS) would come on, L2 & L3 normal
- After a period of time, about 2-3 minutes, the LEDs on L1 would go out
- System working but NO LEDS on L1, L2 & L3 with LED inverter ON
- Various other times, other LEDS on L1 would light up on startup or when comms is disconnected and eventually go out
- System currently working as expected except NO LEDS on L1 (Master)
- Unhappy Customer!
- Need resolution before next visit, return unit to base is not an option as it is part of a working off-grid 3 phase system
I think you are at the point where the solution is three new units. Updated, set up and tested at your workshop in town, load tested, before taking to site.
If the GX is saying nothing that is weird.
But often all those lights together is a power pack problem ruling out an actual install problem?
To be more thorough on site. They get installed as stand alone not connecting by ve bus to other units and checked.
