I post the code here so anyone who wants to use it, hack it and improve it can do so.   Tinker said   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. The Arduino shield board I hacked up has output pins arranged in a way to duplicate the EGS002. I can change from my Arduino drvier to an EGS002 without any configuration changes. Please note: The EGS002 needs to have the opamp removed and a trace cut (permitting the IR2110 shutdown pull down resistor to pull down permanently) for reliable running. In other words, I disable over current cut off completely.   Tinker said   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 . Awesome! Let's see if it works. wronger than a phone book full of wrong phone numbers
