Hi, We have made a board with LORA. It is the main communication and control board to which other sensors are connect.We have some problems with the power circuit of the main board. detailswill be provided to shortlisted candidates.

I need a solar design engineer who can prepare a design, Single Line diagrams, automatic transfer switch , The project is 600 kwp solar panel, with 6 SMA core 2 inverters, Storage inverters, 2 generators of each 350kva,. Hence need to design breakers, transfer switches. Pvsys or equivalent software simulation. SLD in autocad.

The Solar charge controller provide best power delivery from solar panel to 12V battery whether charging a single battery. These PV Logic Pulse Width Modulation (PWM) controllers achieve a constant battery voltage and thereby producing a higher charge efficiency, rapid recharging and a longer life expectancy for any battery. Energy meter to measure Solar energy generation in Cumulative Kwh Count & real time DC Voltage, DC Current, DC Wattage. We have the hardware ready with MCU- PIC18F46K22 with EPROM- BR24G512FJ-3AGTE2…
