I'm thinking about adding 18 tigo optimisers plus the monitoring device which I assume will be an extra £1000 but read that bypassing diodes do the same thing, can anyone explain to me if it's worth forking out of an extra grand for it?0

I'd ask your supplier to look at his prices again as I've been quoted alot cheaper than you - around £32 per optimiser.PV total 19.8 kW system:

13 x 390W South spit over two flat roof areas at 5 to 20 degrees inclination.

I got them to add 18 tigo optimisers and clould connect kit with TAP for £800 which seems reasonable.
