It is an interesting approach you created there,to coax a 50Hz sine wave into the primary. I shall follow this topic with interest and might even rustle up the courage to start tinkering with the arduino I bought a while ago (after madness suggested its usefulness). Writing programs is a bit beyond me since that art progressed past basic language but I should manage to program what you and others so kindly post here. So the idea is to replace that EG8010 adapter board with an arduino based version which can be tailored to requirements. How durable will that then be afterward, when used in a working inverter? Will it be just plug in and let run as the EG8010? Considering one would want a spare board to minimise inverter down time should something go awol in that electronic brain. I can even see an opening for somebody to supply plug in adapter boards for those (like myself) not having much programming skills. At the moment I'm working on an opto isolated driver board which would be removable from the power board where the mosfets, etc. reside on. The drivers are optically interlocked (as per warpspeed) to prevent cross conduction. Another big advantage with this is the control board can be located a fair way off since its output is current based. It would be easy to re do my control board so it can accommodate the sine wave generating arduino. Perhaps we can come up with a truly bullet proof inverter - or is this wishful thinking . Klaus
