Well this morning went on the roof to measure up and the 1.9Kw array can go 10 wide with the 1.5Kw array lower.
I did need more conduit and flexi conduit for the cable tray but the mob I used before was closed for the xmas break so had to go to the big green shed where I got 4 lengths of 20mm conduit and plenty of fittings along with a 10 metre roll of flexi. Had a look at their ali selection and ended up going up the hill to Paramount Browns where I got some 40x6 ali flat bar to use for the panel clamps.
Then this is where it went south on me
the 5/16" bolts I bought were too short and when I went and looked at the 1.9Kw mounts they used SS cap screws into mild steel clamps and everyone is locked tight and 99% of the set screws are bent. Then decided I'd do the cable glands on the box's only to find I forgot got positive and negative so for the 1.9Kw array 10 cable glands and the output to the conduit
So now I can use the big box for the 1.5Kw array but I do need to get a longer box for the other and heap more cable glands.
I got both MPPT boards all finished and with the boards I got from Rodger his idea of using a dingel connector does fit the goods for my boards.
Now the wind here today is pretty strong and plenty to do as have the grand kids here for a few days so may aswell wait until my CRO arrives so i can test the inductors to make sure they will work.
Well Rome wasn't built in a day and as this is a 20 year upgrade another week won't hurt.
