Most optimal solution for AC coupled battery installation
I'm seriously tempted to add a battery to our current set up, but am not very good at math and just not sure which set up would be most beneficial. We are limited to the AC coupled installation due to the solar panels being leased. The solar array that we have is about 3kw (and no option to upgrade this due to the lease).…

Record breaking 2022 for Solar
Has anyone else found that 2022 has been a record year for solar generation? Previously 2020 was the best from the last 11 years but we've now beaten that with a month to go so even if the sun doesn't shine at all for December then 2022 is still the highest for the last 11 years. If December is average we'll have got…

My system's performance - Using PVGIS to get an accurate generation?
Hi all, this is really just a brain dump with a few questions, I may have just got particularly lucky with my install, it's performing spectacularly and I'm not sure if it's 'normal'. I would like other users opinions, especially those with a few years of data under their belt, and also wonder what others put into PVGIS to…

Heat Pump integrated into Hot Water Cylinders (Vaillant, Daikin etc.)
Seems like a sensible way to reduce hot water heating costs without going with a heat pump for the entire household. I wonder if any users/ owners are out there? https://www.ariston.com/en-uk/products/heat-pumps/air-source-heat-pump-water-heater/nuos-plus-wifi-uk/

PV only, or Solar Thermal too?
Hi We're building a new house in Somerset. It'll be very well-insulated and energy-efficient ; almost a "passive house" but not quite ... It'll have an air pump. There are two options for heating: StoreEdge 5.3kW Solar PVs only; or 3.9 PV and Solar Thermal. There will be a 10kWh StoreEdge battery. The PV-only option is…

Impressive Performance of Sharp 400W Panel installation!
Recently helped a friend with his PV install for his Billericay (Basildon) home. 12 X 400W Sharp panels + SE optimizers tied to a SolarEdge 5000 inverter. Aspect is South Facing with minimal shading. We both had clear sunny winter skies yesterday. The nearly 3X difference in generation of 15.5 kWh for the day is a bit…

Uhome LFP 2400 add-on
Hi! I have 3x Uhome LFP 2400 batteries and I'd like to add another 3, but the price I've been quoted (supply only) is eye-watering! Does anyone know a good supplier? I'm hoping that I can install these myself and save cost... Any ideas? TIA.

Solar panels working at night?
My panels are still outputting 28w right now, any idea what the problem is? Clearly they are not generating so why is my Geo monitor saying they are? I have had my panels for 7 years and have never seen this before and this is at the same time as another problem with my iboost which is reading 400w higher than my recorded…

Using air conditioners as air source heat pumps
Fitting an air source heat pump on our terrace has been suggested to us, given that our storage heaters can't cope in winter, and our main room is often below 18 degrees, which is uncomfortable. Electricity costs for our 90 sq. m. flat are now £60/month in summer (covering water heating and cooking) and £220/ in winter…

Discussion ... ASHP(Air/Air) with Solar pv ....
Hi All The combination of a small ASHP(Air/Air) with Solar pv seems to be a valid pairing of complementary technologies which has been raised a number of times on this forum. The idea of this thread is to encourage discussion of this combination in order to validate what an appropriate equipment specification would look…

Solax 5.8 kWh battery with Solax AC Invertor
Excuse my grammar I suffered a severe brain injury several years ago. On the 12th of October a local company fitted a Solax 5.8 Triple battery and AC invertor to my existing 4.4 kWh solar array, I have been chasing this company since the 25th of October for a receipt for payment and associated paperwork, to date I have…

Solar maths not adding up
Hello all, Just want to run this past you, as I am struggling justifying the cost vs gain on solar. I already use batteries that are charged during Octopus Go Rates and last the whole day. My roof (East-West) is an odd shape and being a three story house means the scaffolding price is pushing up quotes. so 9 x 415w panels…

Has anyone submitted a planning application for a micro wind turbine?
Greetings all, I'm exploring the potential of installing a SD3 grid tied wind turbine in a corner of our small garden, to boost our grid exports over PV. It will be mounted on a 6m high Taperfit hydraulic monopole. Right now, the proximity to the boundary wall and home prevent it from permitted development status. This…

Octopus Export : Fixed Rate vs Agile?
I'm with Octopus as my energy supplier, and they appear to have this. I'm not sure what's best RE: exporting back to Octopus when selling excess solar. It appears they pay 15p/KwH as a fixed rate for export which is better than the SEG https://octopus.energy/dashboard/accounts/A-7E6ABF06/switch-to-outgoing/

Battery Bank Switch Relay Timer Base ( DC Isolator)
Hi I have a Solax AC Inverter with a Solax bank of batteries. The limitation of the inverter is that I cannot add more than 3 batteries ( single phase). It allows parallel mode - where an additional AC Inverter(salve)/Batteries can be installed. I want to avoid installing another AC Inverter, however, be able to buy…
