With the 2 × 100 A c.t you get with the Solar bundle, that gives you 5 c.t’s good for 13 mm diameter wires (Solar + EV + 3 on main panel), plus the two for the 16 mm service entrance wires.

Don’t forget to add the power supplies for the emonTx’s.

I’d also strongly advise you to add a programmer. It might or might not be necessary, depending on the other c.t’s you buy, but in any case if you do need to update or adjust anything else in the emonTx’s software, you’ll probably need one. And depending on the cost of carriage, it seems hardly worth not adding one.

So let’s just hope the radio gets through.
