Extra solar install, how does export work ?
I have a 4.6 kW solar roof system installed 3 years ago with a 5kW export permit from the Dno. Next week a 5.9 kW solar system is going on my roof with separate inverter, by a mcs installer with a new 5kW dno Permit. It will have a seperate generation meter, I export to Octopus @15p so when my solar is installed ,do I need…

Goodwe SolarGo 5.6.0 Faulty
I'm possibly the only person here with a Goodwe inverter as part of my PV system, in which case I'm not going to get an answer. But here goes: Goodwe have an app called SolarGo that runs via your home network. It provides rapid updates about what your inverter is doing and can be used to configure the inverter. As of 23rd…

Octopus and Solaredge
I saw this linked elsewhere, upcoming support for some fancy tariff supporting Solaredge batteries. https://www.solarpowerportal.co.uk/kraken-solaredge-grid-flexibility/ Note the article calls the tariff "Intelligent Octopus", it's not clear whether they actually mean "Intelligent Octopus Flux" the existing solar/battery…

Octopus Outgoing and bill delays
So we had our PV system installed in the middle last October and had the export MPAN and the "Outgoing Octopus 12M Fixed" tariff in place for the start of November.Octopus started showing the export payments on the bill starting with Decembers - although I had to get them to issue a separate backdated bill in February to…

What paperwork / documentation will I need from the installer to get registered with my energy supplier (Octopus) for SEG payments?In the meantime, I assume it's just a case of use it, or lose it for any solar generation until registered for SEG payments (may take up to 4-6…

Green & Ethical Investment News and Suggestions
This is a subject that crops up occasionally on multiple threads, so I thought it might be useful to have a thread where we can share both news and also investment ideas that we find. I've noticed that many schemes are as financially attractive as other general investments, so there's no penalty in targeting your monies…

Octopus Fan Club - Discounted energy from your local wind turbine (when it's spinning!)

Investing in a small GivEnergy battery to access Intelligent Flux
Greetings, I’ve long aargued against batteries for low import households…the advent of the Intelligent Flux tariff has prompted a revisit of the numbers, despite the 1550 kWh annual import. As the owner of a SolarEdge system, adding a AC coupled GivEnergy 2.6kW battery would cost ~£2K including AC/DC controller. The goal…

Solaredge with Home Assistant
Hi, I think I've seen at least one reference on here from people using Home Assistant to tweak their Solaredge. I'd be interested in any pointers, and maybe in sharing ideas if I get things running. Where I am at the moment is I have HA running on a Raspberry Pi, and have installed and configured the "Solaredge Modbus…

Tesla Developments
I have started this thread so that people with an interest in what Tesla are doing, or might do next, can post all about it here without being bothered by talk about other EVs. I won't be posting here myself but I can see that there is a community of interest who love to discuss this stuff at length.

Solar Battery Plans - enough?
I have 3.24KWp solar system consisting of 12 x 270w PV panels. When they were installed in 2017, a battery wasn't recommended. I'm now planning to get a battery installed. I've gone for 6kwh because, at £4.5k installed, it'll be paid for by a recent windfall. And it was recommended by the installers. Now I'm thinking - is…

Heat Battery
I heard a mention of this piece of technology this weekend; something I had not come across before. As far as I can tell a "heat battery" works like a thermal store but rather than using water as the storage medium it uses a material that undergoes a phase change at around 60 C. Cooling through a phase change often…

Insulating Eaves of a loft conversion - Have I messed up?
Hi guys, Have an existing loft conversion that has an uninsulated eves in one side for storage with a small hatch on the purlin wall for access. The Purlin wall is insulated, but the small door seem to let in cold air. I want to use the eves for storage, but its not insulated and gets very dusty as this side of the roof is…

Solar panel quotes
Hi all, I have been exploring solar panels and received multiple quotes and whittled it down to 3. I am looking to get 3 panels on my south roof and 7 on my east as it's the maximum I can fit on. Quote 1 - 10 JA Solar 435w with 10 Enphase microinverters. 4100kwh generation per year. £7k cost all in. Quote 2 - 10 Trina 410w…

LG 10kW DC coupled Battery for £4K installed - ideal for SolarEdge PV only systems
https://spgrenewables.com/products/aa9a136 I'm not one to tout batteries, mainly due to the poor return on investment for households importing <4k kWh per year but at £4K installed (including Modbus & hardware), this seems like a very attractive price for an DC coupled LG battery. SolarEdge will honour warranties for all…

EV charging using Solar with Zappi - is it worth it?
I am relatively new to having an EV. We were advised to get a Zappi charger as we had solar panels already. This may seem like a dim question, but I am not sure if I am understanding correctly. My query is as follows: We are on the Intelligent Octopus go tariff and therefore get rates of 7.5p/kWH in the night. We have a…

Green credentials re flying
A number of councils are now adopting a policy to avoid billboard advertising for carbon fuelled cars, air flights and other activities which increase global warming. MSE recently encouraged people to sign up quickly for cheap flights. Is this a good idea, or should MSE be promoting alternative forms of travel which are…
