Yea I intend to put those box's under the panels so they are out of the sun and this was an after thought as if the box's I bought are too thick I'll get a couple of shorter height box's so they will fit.

As I did get the grid tie inverters with both lots they will do for the new MTTP's and with the first one I've stripped there is a raised part of the heatsink to fit the fets and diode on   Now as the heat sink does cover the whole back of the box I'm sure it will keep the fets nice and cool.

Got an email from Digikey saying my order will be here on the 21st   I do finish work on the 22nd for the xmas break so plenty of time to get this done.

In the morning I'll go thru my resistor pile and see if I have all the required resistors and I do have to place an order with Altronics to get the caps which I'll do tomorrow and from my last order with them it only took a couple of days to arrive so I will have all the gear to make the MTTP's. For the large caps I have enough for off the areosharp board  and I'll take the caps off that first board. With that first grid tie board there is 5 500 volt 470uf caps so I'll use them.
