To start could I humbly suggest that the mods create a “Mk2PVRouter” tag on this forum because I think it would be helpful for people specifically looking for information related to it.
I would like to ask if anyone has had success in using serial communication to control the MK2 instead of the typical CT clamps? I’ve searching a lot but I haven’t found an example of anyone who has used a different form of control except for CT.
In my particular case I use grid tied inverters with limiters so my net export is always zero, If I could interface with the MK2 using serial to sent it a watt value to heat the water by then I could implement some logic that will allow me to better control power balances between my battery, house and time of day and predicted weather.
If anyone could direct me to anyone who has done this in the past I would be really grateful, of if they had suggestions how I could approach the problem to fixing it myself it would be brilliant. Thanks!
