Hi Dex, I am using FDH055N15A 150V 156A TO-247-3 Mosfets Element14 PtNo 2825158 STPS61150CW 150V 60A TO-247 Schottky Diodes Element14 PtNo 2806773 Both horribly expensive ... but I figured if I used the best spec I could, hopefully they'll be more reliable and forgiving. And so far I haven't had any fail. I fitted another dozen 250 watt panels on the weekend and hooked up the third mppt. Only thing that's a little disappointing is that the output is quite a lot lower than the other two that each have a dozen 275 Watt panels. While the first two might be pumping out 2,800 watts each, the third one might only be supplying 1,800 watts. Now I'm weighing up if I fit the other 12 x 250 watt panels I have here ... or sell them and buy some more 275 or 300 watt panels instead. |
