My first post so apologies if the question has already been broached. I have just installed a pair of 48v, 5KVA Quattro II's connected to a 16Kw battery bank. All is well, the inverters work fine independently but will not configure for parallel operation. As soon as the second inverter is powered up as requested buy the setup program, an error is reported that they must be the same units (they are) running the same firmware (they are not). The firmware is indeed different (2651493 on one and 2651485 on the other) but I cannot find either version in the firmware download lists... Advice please or am I overlooking something obvious?
Thanks in advance.
