Generation from wind turbine and PV panels to cover loads.
Excess energy from PV / wind turbine to storage. Solar (45kwh storage), Wind (2.5kwh storage)
Batteries to supply balance of load in case of no/low PV/wind
PV & Wind Battery topped up from mains when energy is cheap (midnight to 5am).
Wind Turbine(Victron) to cover ~500W load as often as possible, this should be priority over discharging Solar batteries…
I was able to accomplish the above before by using a sine wave inverter and just having that constantly feed 500W out (when the batteries had enough stored). Any demand above 500W was picked up by the Solar Inverters (Huawei).
Issues:
I am not aware of an ability to say the Victron unit “always put out 500W irrespective of grid loads”.
Islanding is managed by a system that keeps the circuit closed if the grid is present and opens the Victron AC circuit when the Grid is not present. I don’t have to keep this if Victron has a more elegant method.
I can compromise and say that the Victron unit handles some directly connected AC loads on AC Output 1(Think out building heaters, lighting etc) and then only if Grid consumption is outside of the cheap energy hours it helps support the grid should the Solar PV batteries be unable to provide enough energy for the property. What I don’t want to do is have the Victron unit provide energy to the house(from the batteries) during cheap energy hours because it spots grid consumption as the batteries are charging.

I have the EasySolar 2 GX unit, ET112 over RS485, USB <> RS485 adapter, Victron Shunt (for wind turbine input monitoring).
Great news @johnyma22 . What modifications did you make to get it operating and what have you implemented to force the export? Others may be able to chip in if they know what your latest configuration looks like.
Looking at your dashboard you appear to have 300W coming in from Grid with 7W AC loads.
You are charging the battery at 691W with 414W of that coming from another DC source.
The display at the bottom is showing a charge of 343W, is that another battery?
@Sean the schematic indicates the DSU666 is connected to the 3x Huawei 6KL inverters.
The ET112 is currently not working. It is connected as the last device (before the tails) and I have the RS485 installation completed as per the docs and wiring over Cat6E running ~60M (tested voltage on D-, D+ and continuity on GND to validate) which goes into an RS485 <> USB adapter. Termination has been completed on the ET112 Afaik it’s pin 4 and 7 or something? Either way it’s done as per docs.
The light on the ET112 is a solid green indicating correct comms w/ the RS485 <> USB however nothing shows up in Settings > IO OR Settings > Energy Sensors.
Borrow a Windows laptop, or buy a cheapy one from ebay then
The twists need to be maintained right upto the termination point, and is the 485 bus correctly terminated ?
The ET112 only needs a 1A fused neutral connection, and there’s way too much copper exposed on your tail termination - it’s impossible to give fault finding assistance if you dont have the necessary tools or there is a lack of clarity as to how your system is wired.
What function are you expecting the CT on the non Victron inverters to perform ?
I read that I needed an Energy Sensor for what I wanted to accomplish but it appears that information was incorrect (as I have things working properly w/ out them functioning).
