OK, thanks

Thanks Jenki, so 4mm cable and 32a RCBO??

Hello, planning to upgrade our 3 kW inverter to a 5 kW model. Existing connection to the CU is via 2.5mm cable, only 500mm long, and 20 amp RCBO. Do they need to be increased to cope with the 5kW load?

Thanks all, yes you are correct Telford make one, Tempest 200L heat pump cylinder. 510mm high x 1500mm . About £1200.

Is there a Horizontal UVC available that is compatible to an ASHP

Many, many thanks every one, so kind of you to take the time to offer such good advice based on your experience and expertise. I mentioned at the start of this thread that it is early days, and we are a small group of forward looking, active members who can see this opportunity for what it is. The Chapel membership is in rapid decline, about 30+ members, 92% are over 70 and 50% of those are 80+ but some of us don't want to see closure. We have decided that we need to push from the bottom, try to persuade our fellow members to think of their grand children and grandchildren, and the Methodist central office not to cash in this asset and disperse it to national mission projects. The person who bequeathed the land did so for the benefit of our Chapel members. If we were to achieve our objective then we would create a sustainable facility with a less intimidating church environment, which would attract more of the younger community and benefit several generations to come. I would like to compile some ball park figures for the project to support our case but the timber frame companies I have contacted so far require Architects drawings before they can quote. My quickly scribbled sketch is not suitable. I will post again if/when I have any news, and will almost certainly looking for more advice.

EV chargers? that's a good idea I know Instavolt are happy to install in our area. You are right about Architects, we would like to achieve something near PH and were thinking of approaching someone like MCB to supply and erect the shell.

Fantastic, what a lot of useful information, might take a little time to digest but very helpful. The worship space we are suggesting would be about 165m2 with vaulted or semi vaulted ceiling. There would be 37 linear metres of wall space suitable for radiators, would that provide sufficient effective radiators to heat the room from an ASHP? Yes, the existing Victorian, solid brick Chapel is is a nightmare to maintain, and we are for ever calling on the heating engineer to fix the boiler. The Chapel was constructed in a time when there was a membership of 200/300 now we are down to about 40 and outgoing funds far exceed income. We feel the sale of this large building and parking space, along with some potential grants, would possibly cover the cost of the new build. The sketch design we intend to present to the Architect includes two meeting rooms for community use, hire, meetings, craft activities, training, coffee room, etc etc. We feel that by offering a fresh, warm welcoming ambience suitable for worship, Sunday school, meeting/function rooms, suitable for community activities, that we would provide a very low carbon building fit for purpose/use by several future generations. The village does not have a village hall so we would hope to create a community hub as well as a Methodist Chapel. I feel it is our responsibility, as the senior generation, to try and mitigate some of the damage we have inflicted on our precious planet and this unique opportunity is a way of doing that. Unfortunately some people can not look forward and are locked in the past so our small supportive group here in the village have some persuading to do to convince the powers that be that a low carbon, sustainable building is the future. This land was bequeathed by a local member for local use, but not sure the powers to be see it that way. I can see that 3phase and off grid are probably not the way forward. What is an multi split air to air system, who supplies those? Sutton lane site plan 2 (1).pdf

Early days, but before we meet with the Architect to complete the pre-app and discuss our ideas, we would appreciate some advice from you technical wizards. We are hoping to build a new Methodist Chapel, timber frame with high levels of insulation to achieve a net zero building. We have done a simple line sketch of a building that would be fit for purpose, a basic "shoe box" shape circa 26m x 13m which would include a large 30 degree pitched roof SSW facing. There will be a kitchen with the normal appliances and we are minded to install ASHP + UFH. We think the SSW facing roof would accommodate about 40 solar PV panels. 1. Would there be sufficient solar generation to run the Chapel off grid? 2. Additional panels could be fitted to the NNE roof if appropriate and viable. 3. Would such a large solar PV system need to be connected to 3 phase? 4. What are the implications of going for 3 phase, ie availability, installation cost etc?

We are trying to source another 6.3kwh battery to add to our system which would increase our total storage capacity to 18.9kwh. Would that require us to obtain a G99 certificate too?

Thank you all for explaining the inverter situation. It looks like the max inverter possible would be 3.6 without going for the G99 certificate which we don't want to do. Many thanks again

Hello, We have a Solax X1 AC 3.0 Inverter and Solax 12.6kwh batteries. As I understand, although the batteries can hold up to 12.6kwh the inverter will only release that at max of 3.0kwh. If we were to replace the inverter with, a larger circa 6kwh inverter, would that allow us to draw 6kwh to supply a couple of small electric+oil radiators? Would increasing to 6kwh create a problem with the electricity supply company? Our solar panels are rated at 6.2kwh peak

Yes, good point. The description does not mention " working order" and is non comital re condition. Only states "ex display and never been used since purchased a year ago"

Hmm, sounds a bit complicated, this is an embay auction, the accepted method of payment quotes, PayPal, Visa, Mastercard etc. I think MSE is saying if I pay by choosing credit card then the transaction will still go via PayPal and deplete the cover provided by Section 75. This is a private sale so seller does not have credit card facilities himself.

Yes, why didn't I think of that, Radian. Credit card it is and not Paypal

Thanks for all the input, some of which is too technical for me. Yes, it is 6.3kwh and 100.8vdc and of course discontinued by Solax about 2 years ago. The battery I have located would give us 3 @ 6.3kwh to supply electric heaters, and allow us to stop using gas. Cost of the extra battery is circa £1000. There is an experience Solar Installation Technician in the village and would intend to call on his service to install the battery. I just needed to know that I was aware of it's potential issues and that there would be a solution

Thanks that's not as expensive as I thought but still too much for a one off job. Perhaps I could hire one for a day

Wow, that looks like an expensive bit of kit

Many thanks Bill & Mark, I believe the voltage of the proposed additional battery needs to be similar to the one it is going to be connected to. What equipment would I need to charge the additional one if it is lower and does not match? Could I just wait for the existing batteries to drop down to a similar voltage?

Hello, We have a battery storage system comprising of 2 x 6.3kwh Solax batteries, now discontinued, but I have managed to locate an additional 6.3 battery that we would like to add to our system. I understand this battery is ex display and has been in store for quite some time and not charged. My question is , if the battery has fully discharged will it charge again if added to our existing system?

Thanks Steamy Tea, Sorry I made an error in my earlier posting. The modification would be adding cells to the 5.8kwh battery to match our existing 6.3kwh. I am amazed that Solax, with all their technical expertise, can not supply a kit to enable the latest 5.8kwh battery to link with the 6.3kwh model.

When we purchased or retro inverter and 2 x 6.3kwh batteries we choose Solax because we were told the batteries could be easily expanded at a later date. 3 months after installation we tried to purchase an additional 6.3kwh battery only to discover it had been discontinued are there was not any stock available. Very disappointed with Solax, and we have been trying for nearly 2 years to track one down without success, it could be new, refurbished or good used one. Solax now supply a 5.8kwh model and I wonder if there are any solar experts out there that could suggest a way around this problem. For instance, would it be possible for a technician to reduce the number of cells in a 7.5kwh battery down to 6.3kwh to match our existing system? I appreciate that such a modification would negate any warranties. We want to go all electric but Solax have dropped us right in the you know what.

Hello, will a Solax Hybrid X1 5.0D inverter work of grid power supply only. ie no solar PV available

We have solar PV and Solax battery storage in the house. We want to increase our storage but Solax no longer make the battery that we have ie 6.3kwh Gen 2 triple power. Our garage has a CU fed from the house via a 2.5mm cable. Could we fit a 5.8 battery and inverter in the garage, connected via an RBCO in the CU? The plan would be to charge this extra battery from our Octopus Go off peak. Would the extra battery automatically feed into the house load or EV charging when required? I have chance of a very good deal on a Solax 5.8kwh battery and 5kwh inverter. Kind Regards, Ian

Yes Nick, indeed I have. In fact I have installed quite a few UVC's in the past but not since 2010 when the G3 certification was introduced. I was close to retirement at that time and decided not to undertake the courses required to get a ticket. Instead I spent my remaining working years installing kitchens and bathrooms as a subby for a local improvement store. I still have my tools and quite a few fittings etc so feel confident I could complete the work correctly and safely, albeit somewhat slower these days. We can create a space in the plant room circa 700 wide x 630deep and 2400 high so a standard 250L cylinder + pipe work,fittings, expansion vessel etc should fit OK. I have seen on line Gledhill 1603 high x 530 @ £410 and Telford 1330 high x 554 @ £540. Can you suggest/recommend a cylinder that you would normally to supply to your customers? I would of course welcome any up to date tips, suggestions etc you might think appropriate Regards, Ian
