Somehow I got into the distributor program of SOLAX UK,
They run training courses, last one 13th Sept 2017, planned start sales is Oktober 2017
MIII X-Hybrid 3-phase series,but these are meant to work with high voltage 170-500V batteries,
so more complicated to manage using a diy BMS system, given the number of cells to control.
Still think Batrium could be a good option
They push LG Chem gen 2 as battery option,
