... On the charging side, we have seen that the batteries are being destructively charged to the point where after some time they are do not hold charge. This occurs typically after 3-4 Months. [Also], when the system is placed under load, the output frequency of the alternator oscillates between 30-60Hz. There are a number of reasons for this, and our engineering team are looking at solutions. We have thus gone back to the drawing board. ... -------------------------------- This is not unexpected. Several people have noted a similar effect on batteries when running a system similar to theirs. We mentioned in our first story that Alexandros Xanthoulis of Defkalion said he saw such an effect at a university in Greece. ....
