Update, there has been a bit of discussion about disabling the overcurrent protection on the egs002 board (which is used on this inverter). The reasons for disabling were to do with poor shutdown control when triggered sometimes resulting in blown FETs. The disable procedure i think went something like, remove 393 SOT and jumper pad 1 to 4 and short pads 7 to 8.
If you find that procedure difficult to maneuver and really dont want anything to do with current limit there is an option. Just snip or break pin one (IFB) off of the egs002 board and plug back into its edge connector taking care to line up with original hole positions and your off to the races, no overcurrent trouble to worry about, use fuses or breakers.
Why do i know this and why did i do it?
The voltage feedback uses isolation transformer which insulates control circuit from any ground loop problems that might influence the sensitive voltage control circuit. If you omitted the tiny Vfb isolation transformer you would have all kinds of miserable problems.
The IFB doesnt have a means of isolation, (though you could make one) my system developed a problem where the overcurrent protection would trip out at random. When this happend it would shut off power to the house and my controller would switch to grid then after 16 sec the inverter would start up and do it all again. There is a small delay like 44/100 of a second for an unplanned power failure transfer this of couse isnt friendly to some appliances. Too much info i realize but you get the point. Having your main battery inverter switch off randomly through the day isnt good. I tried figuring out the real source of the problem, finally thought i nailed it when i noticed it occured instantly when relay contact closed for array 1 to grid tie 1. Great i thought now i have it cornered. Very little rain this summer but i noticed this problem only occured after a rain. So i grab a meter thinking the array has high voltage leaking. A 10mohm input meter showed 6v max of leakage between either hv terminal to ground. Scratching my head i thought, i dont need the power right now, ill just leave the array unplugged. Believe it or not that afternoon the inverter did it again even with the offending array unplugged. So id had enough, had wasted a good 4 hrs, had pulled new wire in underground conduit to the array etc. Shut power off to everything, removed board busted pin off, plugged back in and hasnt been a problem since. I might do something with an optoisolator later but for now i like it. I dont think overcurrent shutdown ever saved mosfets from a screwdriver across the output leads anyhow but could be nice if you use yours to capacity. Mine usually only runs at 1/2 capacity.
