3 x 12kw 3Phase Parallel PV Throttling on Master
I had 3 x 12kw 3Phase Parallel Units installed 2 Months Ago with 63 x 545 Watt Panels in 6 Strings. 2 per Inverter with 66kw of battery.
The Problem is that the Master Unit Starts Throttling the power from the panels connected to it, when the other units on the other inverters come online (Sunlight). When in direct Sunlight the Master only delivers 4-5kw (Previously 1-2kw before firmware) and the Slave 1 and Slave 2 are delivering 10-11 kw. If I disconnect the Slave 1/2 Panels, and Disable the Parallel on the master, The master PC shoot up to 10KW. The big drop in PV Supply is when the Batteries are fully Charged.
I have spoken to Tech support, they have updated firmware, but after a couple of days, the issue is back.
Any Ideas of what to do.

Just a note. This was finally resolved after 2 Months and 5 firmware updates. It was a firmware issue causing the master to throttle, when the slave Inverters started producing more power.
