I need to hire the inverter hardware design and firmware developer either together or separately for development of my hybrid inverter. Those freelancer having very good factory expertise and independent manufacturer with capability to deliver the project on time only can apply the same. Payment term:-The work has to deliver on time and If the work meets the technical specification, then only payment will be made. The payment will be discussed before awarding the work.
The glance of specification is given below. However the logic requirements shall be given during awarding the work. As per the requirement, complete design, schematic preparation, BOM list, firmware code, Proteus simulation and offsite support for 3 Phase ongrid solar & battery hybrid inverter along with MPPT suitable to operate in ongrids mode as well as island mode based on the requirement. during island mode of operation, the inverter should recharge the battery banks through its inbuilt 48V DC boost battery charger which will operate through 600V/48V DC-DC bidirectional circuit. The MPPT should control & manage the solar PV voltage fluctuations and give a constant 600V Dc output to DC bus/ inverter input. The inverter output is 10kW 415V, 3 Phase, 50Hz which will have inbuilt grid synchronization circuit as well output EMI filters. The scope includes offsite testing support during prototype work. Total 4 nos of micro controls model no- dsPIC33FJ32MC204 use for MPPT, Inverter, DC-DC bidirectional inverter and battery charger. The single line diagram is enclosed for your reference. However detailed operational logic will be provided after awarding work.
