So a 7.4kwp PV with a 5kw inverter and a 10kw battery, sounds ok to me.4.3kwp JA panels, Huawei 3.68kw Hybrid inverter, Huawei 10kw Lunar 2000 battery, Myenergi eddi, South facing array with a 15 degree roof pitch, winter shade.1

Agreed, £13k seems pretty normal for that size of system in the current market.EcoScruples said:So a 7.4kwp PV with a 5kw inverter and a 10kw battery, sounds ok to me.

I'm paying 1k more for two of those batteries and two inverters ( gen2 3.6) with a similar size array and Tigo optimisers- but I placed my order at the end of March, so may have got lucky.PV total 19.8 kW system:
23 x 420W East/West split over two flat roof areas at 10 degrees inclination.
13 x 390W South spit over two flat roof areas at 5 to 20 degrees inclination.
6 x 390W south wall mounted at 90 degrees inclination.
7 x 390W West wall mounted at 90 degrees inclination.
2 x 5 kW hybrid inverters
4 x 9.5 kWh batteries (38 kWh total)1 -

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

Here is a bit of reading that may help.

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.

That seems better, TIGO optimiser prices seem to fluctuate almost daily, I've also TAP monitoring with mine. Good luck with your install if you've settled on this option.vienly said:94JDH said:I'd ask your supplier to look at his prices again as I've been quoted alot cheaper than you - around £32 per optimiser.
I got them to add 18 tigo optimisers and clould connect kit with TAP for £800 which seems reasonable.
so all that grand total £13800PV total 19.8 kW system:
