Self-employed embedded software and hardware engineer. Consultant for PV power storage and general power supply solutions. Working on storing surplus PV energy in LiFePo4 batteries for grid tied and off-grid situations. 20+ years of experience in industrial power solutions.
Have my 1.8kWp PV test system installed in July 2011. Main purpose is for testing of PV storage solutions. An then I am also interested to know where my consumed grid power really goes. I have a three-phase OEM system installed together with three temperature probes and Emoncms running on a
Raspberry PiWindows Home Server.
Second system running in parallel consists of an Eastron SDM630 three-phase energy meter read out via RS485 and Modbus by a RaspberryPi with Emoncms 'low write' and RS485PI addon board.
Added another 1kWp PV system with battery storage. Uses an MPPT charge controller to charge a 24V 240Ah LiFePO4 battery, which is discharged by three AEconversion micro inverters to compensate the self-consumption on all three phases avoiding any feedback to the grid.
