Glad you have got your setup optimised. Would be interesting to see how it performs over the summer and how much (if any) you’ll need to pull from the grid. Good work.
Good to see the update. If you can get import at 9p/kwh then surely as long as you can go 20hrs on batteries then exporting all your solar pays 15p/kwh? I can't remember which ev charger you have, I assume it's not a zappi or ohme as then you could go on Octopus Intelligent Go, for 6hrs at 7p/kwh?
FYI your charge at 10p/kWh doesn't work out as your import rate as you're not adding in the losses from the battery & inverter which workout at 12% give or take. So charge at 10p/kWh costs 11.2p/kWh discharging. Considering tracker at approx 18p/kWh you're only saving 7p/kWh but you've spent over £20k on batteries. For most consumers this doesn't make sense, but if you're a higher user it may, but Octopus Tracker does put a big dent in break even date. That said, I do love your set up, so jealous
Loss from grid to battery and back out is around 5%. Now on 7.5p off peak, and additionally not for 4 hours but 6 now. Super cheap, break even at this rate much much sooner!
@@IanSampsonRLO I have the FOXESS Energy Cubes & the % difference between cumulative charge/discharge efficiency is 90-91%. A 10% loss from battery storage is common. How are you calculating losses?
It'd be easier if you could use the cars as storage for the winter 🤔 well at least if you didn't use them in the winter ? You'd need an ICE vehicle for winter 😂
Expecting my new battery this week from Company called Fogstar 15.5kwh battery for £2500 Should of been delivered by now but some issue with courier. Have sold off my plyontech batteries for arrival of new double capacity. Have not seen any reviews of this battery yet. Be interesting see how it goes ....
Oh no you're not you could be using a second hand car battery and the battery emulator on some lilygo. Since you have two inverters you could have have two kona/niro packs 64kwh each i.e. 128kwh probably for the same price as the oem ones you have there.
