Expecting 4 guys today to install heat pump and fit solar panels but only one guy appeared. A fair bit of coring through walls and fitting copper pipe was completed. The pump hadn’t arrived in the morning but turned up at about two o’clock so he concentrated on fitting pipes.
Program for tomorrow is complete heat pump install and fit the solar panels. The electrician needs under the floor to cable from the fuse box to the garage so a bit of work for me to lift the carpet to allow access to the floor hatch.
The electricity and heating will be off for a few hours so I will take the wife to my daughters until work is finished for the day.
I’m hoping all the work is completed by Thursday š¤

Peak sun hours is an important factor to take into account when considering solar but, panals don’t need direct sunlight to work, so will harness power regardless which way they are facing, by how much varies by location and obstacles such as trees causing shadows.
The ultimate in systems be power systems that automatically followed the sun and tilted a few degrees more during winter but, one has to be realistic with their expectations.
I woyldn’t rush into a decision re the batteries untill you have fully weighed up the pro’s and cons of each and the overall size realistically needed. Asking on solar pv forums, will also gain additional valuable knowledge alongside what you have already had, so you are competant in the decision you make.
My single phase SolaX inverter and 5.8 battery charges and discharges at 3.6kWh, it can support up 3 3 5.8kWh batteries, charge and discharge would still be 3.6kWh
Thanks for that Oscarmax š

Anything i post over three lines long please assume it is an article lol.@kezo my new air source heat pump can ādrinkā electricity. There have been days, when really cold, that I’ve used 82kwh in a day to run the house so being able to fully charge then discharge each day is essential to make the figures work as I had assumed that 45kwh of storage would run my house even in the coldest days. I now know that isn’t the case so if the amount of energy I can get at cheap rates reduces even further it will really mess up my calculations. Not only for running the house but for selling back to the grid.

Anything i post over three lines long please assume it is an article lol.Sorry the 82kwh was for running the house including air source heat pump. The pump probably used around 65kwh.

Anything i post over three lines long please assume it is an article lol.Rather than a 5hr 2 rate tariff (new economy 7), have you considered economy 10, which can give potentially 10hrs of off peak rates however, the rates can vary depending on time of day and the peak rate can be higher, so you would have to look into such a tariff, to see if it would fit your needs.
Just recieved this from the technical department of Bimble solar.
āThe Dyness should be fine with the Sunsynk. The ECCO 8.8kW can charge at 190A. In 5 hours it can therefore do an absolute maximum of 950Ah. Each Dyness module is 100Ah, so within a 5h window, they should be OK. Normally batteries are not completely discharged, so not requiring a full 900Ah to get them back to 100%.ā

Anything i post over three lines long please assume it is an article lol.Just a bit of info on the heat pump. The efficiency of the unit is called the COP which stands for coefficient of performance. They say that a COP of 4 and over is achievable on the most efficient units, to date I am achieving a COP of 2.5. This means for every KWh of energy I put in the unit it produces 2.5kwh.
There is also a value called the SCOP which is the Seasonal Coefficient of performance and refers to the efficiency over a year. I will be tweaking the pump controls over the next few weeks to see if I can improve the efficiency but the SCOP will be the number I will be most interested in.

Sunsynk inverter adapts Li-ion battery charging to self-adapt to what the battery BMS tells it to do. In other words its supplies only what the battery BMS calls for. The inverter won’t be 100% efficient but, will not cause a bottleneck imo.
The Dyness DL05c charge and discharge currents plus batter temp will play a part in the absolute maximum it will sustain a charge/discharge.

Nightmare Kezo, he came back from holiday on Monday last week and told me he would stick with the original Fogstar battery. He indicated he was in contact with Fogstar and the order would be placed.
I asked him to give me the order number but I received nothing. He contacted me on Wednesday last week and said the person who makes the purchases is of and will be back on Thursday. I again asked for the order number as soon as the order was placed.
I received a phone call from Fogstar on Friday saying he had been in touch and asking if I still wanted to use him after all the bother. I explained that I have no other choice to go with him. The girl said that unless he orders today I would miss the end-of-February batch of batteries. Isn’t him a text telling him this and later on Friday received a text from him saying the order was placed, but still no Order Number. I tried to call Fogstar for confirmation but they were closed.
I received an email from Fogstar in Monday morning giving the order number but telling me he had missed the end of February batch and that they didn’t know when the next batch was coming. They have however given me a discount and offered the new 16kwh more expensive new battery for the same price.
They don’t know when they will arrive as their manufacturer is on holiday until February so they will be able to tell me when they returnš¤
That’s not all sadly, I noticed before Xmas that the solar system wasn’t producing anything, well a few kwh here and there. I contacted them but they were closed for two weeks over the Xmas period. Last Monday the electrician text me saying there was a problem with a Meter and that, after speaking to Sunsynk, he would get an Eastron Meter replacement and get it fixed ASAP.
I have since been told by the boss that the meter is out of stock and wont be in until then end of next week. I have again asked for the meter serial number etc to purchase it myself from the web but once again no answer from the boss or the electrician.

Anything i post over three lines long please assume it is an article lol.So sorry to hear this mate but what a company! Have they been going long?
The Eastron meter is probably the SDM120 but, there are severa versions of it however, they are widely available if they shopped around. Send a pic and will confirm but, you shouldn’t be buying anything out of your own pocket.
Fogstar are a great company and glad they are looking after you, even though its not their problem. Not seen the new battery but, most likely an kW upgrade on original?
You should consider seeking compensation from the instaler.
They have been going about seven years I think.
As far as I’m aware it’s not a straight replacement but I’m sure they could get a replacement if it suited them.
Fogstar have said they have a company who could take over so I’m going back to them to get their details. I will then go to The Energy Trust to make sure they are acceptable to them and to make sure I can change at this late time in the contract.
There is a snagging list and the replacement consumer box to be sorted so its not as tidy as I would like. On the topic of the consumer unit, don’t know if I’ve asked you this before, what should I be asking for with the view to adding an EV charger in the near future.
I will be looking to recover the money I’ve lost due to the additional cost of electricity 25p as to what I would be paying with the batteries 8.5p.

Anything i post over three lines long please assume it is an article lol.You need a couple of spare ways in the consumer unit, for future upgrades however, EV chargers supply normally comes from a stand alone consumer unit in most cases.
That’s great kezo thanks

Anything i post over three lines long please assume it is an article lol.Brydo I know you are getting some serious grief at the moment, but eventually it will sort itself out and you will be pleased.
Unfortunately I have suffered a brain injury and occasionally say the wrong thing.
Oscarmax i look forward to some good news we’ve had two family deaths over the Xmas period and I’ve been diagnosed with prostrate cancer. Thankfully the cancer is low-grade so no panic but still not nice to hear.
The only good news is the heat pump is working well, touch wood.
I agree that when its all done I should see the benefit and all the these problems will be a past memory.

In 2008 we built a large environmentally friendly house, I let the wife chose anything she wanted, fortunately the wife has a level head, as always at time we had some grief but when it was finished wow.
Sorry about your bad news.

The Eastron meter is normally used when your Inverter is more than 10m away from the incoming mains to prevent inaccurate readings.
Sorry to hear you have prostrate cancer mate, are they watching or doing anything about it?
They have suggested monitoring it with regular blood tests but I’ve asked to get it removed via radiotherapy. I’ve still to speak to the radiotherapy department and that’s likely to happen in March. They may say its not required but the feeling I’ve got is they will do whatever I want.
My inverter is only 5m from the mains š¤
I’ve contacted the company the boss said were out of stock and surprise surprise it isn’t. Its only Ā£40+ so I don’t get this guy he is causing problems for no reason.
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.Kezo would the fault in the existing unit affect the solar system as a whole. Even when panels are in full sun the system is producing very little. Is the system actually producing but the existing meter isn’t recording it?
I obviously no nothing of these meters I went to them complaining the system was not performing and they have came back with this as a solution but us it the only problem there could be to cause this under performance?
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.There are many reasons a solar system can underperform from something wrong with the installation or damaged panels or other equipment from the factory, to the system is working as should but, not being recorded correctly for one of several reasons, existing CT clamp fault or installed wrong way round, even doubling or more up on twited pairs solves many issues however, its not something l’d like to hazard a guess at from miles away.
The installer seems to think installing an Eastron external meter will sort it, which I assume they believe the system is under recording, so you have got to give them a chance to sort it initially. They may not know what the problem is hence the reason the part is out of stock, so they have time to search/enquire for a solution however, telling you over the phone rather than comming out, indicates they new there was a problem with your system imo.
It maybe worth getting advice of energy Scotland on your next steps and if you haven’t allready done so enquire if you can change installer for the battery, as itsĀ all been going on too long with too many iccups along the way.
I would be inclined to get my prostrate removed if I had it, sadly it runs in my family and my dad passedin December after a 6.5yr battle with it, but his was advanced when first detected because doctor kept forgetting to put the blood test on his yearly checkups.
Thanks for that kezo, I’ve been in touch with Fogstar and I have passed my details to them which they will pass to the Ā installer they contacted. Once I’ve spoken to them about install costs I can make a decision on the way forward.
I’m sorry to hear about your dad kezo losing a parent is heartbreaking, I hope he didn’t suffer. My mum passed last year with all of us at her bedside one minute she was here the next she was gone, so sad.
Yes my prostrate cancer diagnosis is not great but as I said its probably the best outcome, other than no cancer, as its low low-grade and will probably take many years to become a problem, if at all, but I hear what your saying and removing it completely is the only sure way to prevent prostate cancer. My friend had his removed in October last year and seems to be doing well. His cancer was more aggressive than mine so that’s why he chose to have it removed.
On a lighter note can you give me an idea of how long it would take to replace the meter. I’m trying to get my head around why this guy is taking so long to do everything.
