Solar DC/DC Optimizer

Hi all, I'm Looking for someone who can Build a DC / DC Optimizer with DC Powerline Communication. Following Requirements: Optimizer: Voltage Range: 10-60V Amp Range: 5 - 18 Amps Efficency > 99% Max Dimension: 120*80*40 mm Low Power Consumtion Buck Bost Converting PCB and BOM should be not Cost more than 10 USD EMV Approval, CE Approval ready Wather Proof Housing Function: - 2 Set of MC 4 Connector - 1 Set Connected to the PV Pannel - 1 Set Connected to the String - DC Power Line Communication - Detached the PV Pannel from String - Measure V/I before Buck/Boost Converter - Measure V/I after Buck/Boost Converter - Send Periodacaly the Value's to the Power Line Communication Host - Host can send Desination V and the Module will Convert the I to Reach the V - Host can send Destiation I and the Module will Convert the V to Reach the I - Mixed Mode between V and I - Optimizer should adust the V/I periodicaly time who is setted over DC Com Line - All Optimizer should be adressable for easier find DC Power Line Host: - Should Communicate with all Optimizer - Should send the Destination V and I - Should track the Power of whole String - Should send all Data to a Interface CAN / WLAN etc. Greetings Fredi
