-When the batteries are full, we still have PV power available, but our grid operator doesn't allow feeding or we have an off-grid system, that power is lost. We could use that power and send it to a boiler or something similar. For this we are using a device from My PV called AC-Thor.

 Please check the firmware version on AC-Thor device, must be at least a0010006.
+Go to setting and select the “Mode”. For ESS select ”Hot water 3KW”, .
+{{::ac_thor_frequency_mode.jpg?nolink|}}
+ In order to have communication between the Color/Venus GX device and Ac-Thor, some parameters must be configured:
+On Signal Source, select “Adjustable Modbus TCP(Sunspec etc)”.
+Device ID must be 0.
+Metter Register 820, Int16 and -feed in.
+For Scale Register, don’t select anything.
+For Modbus Port, leave the default value (502).
+ On the IP address field, you have to put the VenusGX/CCGX IP address. If you don’t know how to obtain it, please check here: https://www.victronenergy.com/live/venus-gx:start
+On the Control target, recommended value is -50W.
+{{:ac_thor_controll_type.jpg?nolink|}}
+Press Save to store the parameters.
+On the Venus/Color GX please be sure that Modbus TCP is enabled (Setting, Services, Modbus/TCP)
+{{:venus_modbus_enabled.jpg?nolink&400|}}
+Also in Setting /ESS, Feed-in excess solar power must me enabled for system with PV panels connected using MPPT’s  and Fronius Zero Feed-in must be disabled for systems with PV panels connected using Fronius PV Inverters.
+{{::venus_feed_excess.jpg?nolink&400|}}
+If everything is correctly configured, you should see in the information screen of the Ac-Thor, the grid consumption/feed displayed as Meter measured value, positive for consumption and negative for feed in:

+AC-Thor will control the energy sent to the boiler so that the energy sent to the grid is approximately 50W.

+To prevent boiler to over heat, please be sure the temperature sensor is connected to AC-Thor and installed inside the boiler. The temperature parameters can be configured in the settings menu:
