Hi
I have hit a snag in my system.
I have a Growatt SPH 3600 hybrid inverter, and a victron Multiplus II 48/5000 diy kit (with color gx). They are each their own phase. the Growatt has 6000kw solar attached.
I have two further solar systems
a SMA setup running at approx 6000kw
and a series of 250 panels with microinverters theoretical 6000kw, in real life they suck and are about 1500kw.
I had hoped that i could just set two smartmeters (Growatt runs rs485) and Victron runs a EM24 TCP up in the very front of the electric board.
Both monitor all three phases. I was hoping that they would kind of just balance, but in the end the Growatt discharged into the Victron system. I tihnk some sort of ramp up occurs. So the smallest difference in measurements, will cause one to start the ball rolling, and steadily increase effort to deliver consumed electricity.
I dont think i can change much on the config on the Growatt, so im down to the Victron, and splitting the system into phases. This sucks because i would then have to decide what supports what and have one phase i cant cover.
A physical work around is to isolate one system and its consumption to an early place one one phase, send remainder of the phase to the one covering all three phases
An alternative angel of attack is the build a man in the middle for the victron, so i intercept the EM24, modulate its values to half. In theory i would have to do the same for the Growatt rs485. This will take time and i'm not sure i will be able to complete the task. By doing this i can send a percentage of the messaured values to the device.
Im currently leaning towards rearranging the physical flow (phases), but it requires an electrician to spend considerable amounts of time rerouting my cabling. (law requirement).
Does anyone know if i can make like a deadzone in the victron, like you can with game simulation wheels ?
Or can you recommend some sort of clever fix... i'm all ears.
One recommendation to everyone else.... buy one big system, don't do like me, i bought used equipment below wanted scale. Not the smartest i have ever done.
