Help wanted


Can anybody help me?

I want to use an emonTX unit for load limiting.The unit is to monitor the output from a large PV system.
We are only allowed to export 80 Kw max across 3 phases back to the grid. So we would need to add a relay board to the emontx unit and write a sketch to open the relay when export reaches 80kw. The unit has to be fail safe,(the relay reverts to NO state if power fails or no input data received)
We are so looking to develop an emon unit that can deliver a 0-5v or 0-20ma variable output signal dependant on the level of export. The idea behind this unit is to ramp down the invertor output dependant on export level.
We are not looking for any bodies help free of charge, we are a commercial business and expect to pay for this help.
