Hi (completely new to this forum) Andrew Deacon - Namibia
I have the Mecer SOL-I-AX-5NB inverter KW 4500V. I live on a farm in Namibia completeley off grid. 3 Inverters 3 fase with 2 X SolaMd 7.4KW batteries. I have had numerous problems of which I read on your forum (premature floating & Over voltage). I upgradedfrom 71.50 firmware to 71.82 - that solved some of the problems. My problem is it does not communicate properly with the battery software as well. Can I try the 71.94 firmware on this inverter?
