The system is all our own design - we are not using third-party relays.
We now have a draft INSTALLATION MANUAL with wiring diagrams on our web site
here. (scroll down to the PPS section)
Surely not? Not to be an a$$, but do grow your own chips, make the relay housings, weld to the chips etc? That seems to be a high capital/volume business? Teach me something new.
Oh - Most solid state have a voltage shoot through issue, and thus a rated, validated voltage for robustness, and seem to derate at some ambient temperature.
How is the errant voltage handled, and what is the full amp rated temperature environment capability? I LOVE solid state devices that are properly designed for robustness, simple and the ultimate in reliability and life.
One more thing - I am sitting with the parts to assemble, and see that electrical systems are like DNA, no two are alike. Some commonality here for schematics, locations, mounting holes, wire routing that allow for building rather than design with a drill and crimper instead of a mouse and solid modeling would certainly be welcomed, at least by me. Cost is an object, as I have a relatively simple panel and it still cost more than my first house and first 4 cars combined.
Thanks for including your potential customers in your process, that is your best idea. Having worked in a research department for 10 years, the most difficult thing was to interpret what customers "wanted" from what they would "buy" and what they really "needed". The best process (of thousands that did not work) we used was the analytical hierarchy process, AHP in a comparative matrix. Happy development!
