I managed to solve the problem by changing two of the inverter’s output phases. It seems like when the inverters changed over to battery mode, they lost reference of the phases if it makes any sense…

Hi Guys. Can anybody please advise why a 3 phase motor will turn the wrong direction when the inverters are in battery mode and when in hybrid mode, it turns in the correct direction?

I've noticed now that if I disconnect the Panels before the said tripping time, the Inverters doesn't trip at all. It leads me to believe that it's most probably DC related then, the fact that no batteries are connected to the inverters could play a role here, or am I barking up the wrong tree?

Is that with a multimeter or according to each inverter's display? It's with a Multimeter. I would suspect a neutral problem; all the AC-in neutrals should be commoned, and all 3 connected to the grid neutral. I don't believe that these inverters can operate properly without a solid neutral back to the utility transformer. All AC neutrals are commoned and connected to grid neutral, I'll just check connections again. Presumably, the three inverters are set to 3P1, 3P2, and 3P3 for output mode (setting 28). Yup, that's correct.

Hi Everyone. I have three x IFS V2 "5kw" hybrid inverters connected in parallel and setup to support 3 phase equipment and one inverter in a phase. Each inverter has its own string of panels hooked up as recommended. There's no batteries connected to the system currently. The problem I'm experiencing is that everyday at roughly 17H00 the inverters trip and give error codes, and I don't know why or what's the cause. The first inverter connected to phase 1 shows error code 80 "Can fault". Inverter two connected to phase 2 and three connected to phase 3 shows error code 52 "Bus voltage is too low". I've measured the Utility input voltages on each phase and found a bit of inconsistency there, 190VAC, 225VAC and 240VAC, not sure if it could be the cause though. Any advice, feedback or suggestions would be much appreciated. Thanks in advance.

Thanks for the feedback Coulomb, much appreciated.

Hi Guys, not sure if this has been discussed on the forum yet. Can anybody please advise which Lithium batteries are compatible with the 5kw - V2 inverters? Thanks.
