I've got a tricky question. I have a very good system in place.
2x Multigrid in Parrallel
20kwhr BYD BBOX
2x AC coupled Solar Systems one on the input and one on the output
3x DC coupled solar systes (all Victron) MPPT
1x Energy Meter
Works great, the minor issues and solutions I'm looking for are
1, On the colour control the Green AC load section has a PV inverter connected to it, which I cannot read with the Victron due to its locality, which I don't really mind but it only ever goes to 0W when in reality during the day it should display a negative reading. Can this be worked around or changed?
2. Where I am in Australia there is a maximum 5kw Grid feedback rule and unfortunately the Victron cannot do total export limitation to 5kw, controlling all inverters/mppts or can it? - Assuming it cannot as I don't think it can I have worked around this by having exactly 5kw of AC coupled solar and have turned off "Feedin excess charger power". This issue is during the day I would like the AC coupled to sell back and let the DC coupled power our loads but what actually happens is the DC coupled gets shutdown and the AC coupled powers the loads only providing a limited export. Any ideas on how I can get the AC coupled units to completely export and use the DC couple to power the loads?
Below is a photo of whats going on showing that DC's been ramped down and the AC coupled is powering everything, whilst the green AC load reads zero.
