Battery monitoring for a solar powered system, with LCD display. You may want to monitor the following parameters: Battery Voltage level, Solar Voltage level, Solar current/power delivered Relevant Skills and Experience I have designed this kind of systems. I have experience designing Solar inverters, Solar monitoring systems. Will be able to do this project. Specifications will have to be lot more elaborate Proposed Milestones $888 USD - Project delivery. Final price will depend on final specifications It is not possible to calculate amount of charge inside the battery , unless we monitor current flowing in and out of battery at each cell level and also specific gravity, which is difficult. We can only monitor the Battery voltage level. We can make the system which monitors Battery Voltage, Solar Voltage, Current following into Battery from Solar panel, Total duration of charging and cumulative power delivered from Solar and Battery body temperature, in a a line 16 character LCD display We can design PCB, develop firmware for it and test it and deliver it There will be separate charges for PCB design, PCB manufacturing, Firmware development and testing and delivery Budget will not be small. :( Can we discuss further? Thanks
