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…

How do Sunamp heat batteries work?
So, essentially the above. Can they work with heat pumps? Is the idea that they basically store energy overnight, ready for use in the morning? Would that energy be enough for winter too? Ie: for more than just water heating? I'd love to finally get away from gas entirely. This is also something I'd do after getting an…

Help with battery settings for grid charging
Hi wonder if anyone can offer advice on battery charge from grid. Just been swithched on to Octopus Economy 7 from 00:30 tomorrow. All the research I've done makes me think these settings are correct, but if anyone can spot anything wrong I'd appreciate any advice, thanks

iboost problem?
Now that we have a little sun i have noticed a small issue with my iboost and buddy. Steady sunshine yesterday and today and noticed that my iboost was sending more to hot water than i was actually producing according to the iboost and my Geo solar display. Have checked this morning that the Geo display matches the…

Converting energy consumption into kWh/annum from new EU energy labels
While shopping for a replacement Siemens A rated dishwasher, I found it quite difficult to compare energy consumption figures over my existing 5 year old Bosch unit, which has its consumption listed as 262 kWh per annum (vs. the new metholody of 54 kWh per 100 cycles). Thought it may prove useful to know how to convert the…

Solar Battery in Cold temperatures
Hello, can anyone tell me if a Solar Battery installed in a cold garage has less stored energy in the winter than in the summer? I had my Solaredge 10kWh (9.7kWh usable) battery installed recently in November and noticed I get approxtimately 6.5kWh- 7.5kWh of battery power after looking at some charts and numbers. At a…

Solar or ripple wind farm
Hi About to start looking into this. Other than the uncertainty about paying tax on ripple are there additional benefits to going solar vs ripple?

How much energy does your inverter/BMS use?
I guess this is a question more aimed at hybrid inverters. Given the poor weather for generation at the moment, the amount of energy consumed by the inverter and BMS to keep them operating becomes more apparent. It is even more noticeable when there is no cheap-rate electricity to charge the battery (Agile rates for me at…

Boiler flow temperature regular boiler
Grant Shapps would like everyone to turn their flow temperature down to 60 degrees. I have a conventional condensing gravity-fed boiler. I do not think that the temperature reduction works for me. I understand that a house has a "design flow temperature". What would the likely flow temperature be for a house newly built in…
