  1. Is there a device I can add to limit the output to 3.68kw?
  2. Solis is G98 and G99 compliant but not G100 😞
  3. That looks a lot simpler. My set-up is single phase so the limit looks like 16kw but I will check with Western Power. I'm planning to use a Solis RHi-5G Hybrid inverter and and an 8.8 (max)kw PV array plus Pylon US5000 4.8kwh battery. It seems DNO will require me to provide some sort of export limiter to ensure export to grid can not exceed 16A. Any suggestions for simplest way to do this?
  4. AndyMB did you get this sorted? I've just discoiverd I need to complete the G99 forms as well and am just as confused as you were. Any advice or sample form would be really helpful.
  5. For info panels are in roof intgegrated type and the informal approval was for PV only and suject to a G99 approval once system design was complete. Ive only recently considered the option to add batteries so can see this will create more issues. Hence the post on here for some recommendations.
  6. Hi, I'm looking for design guidance and recommendations for best Inverter & storage options for a DIY install as part of a new house build. Im not looking for an MCS FIT approved system but just to get maximum benefit from solar PV at lowest cost and would like the capabilitty to run off battery power during the evening and ideally during a power cut. I have a qulaified electrician ready to connect up the system, but I'm a bit confused by all the options. So far I have purchased 24 x Canadian Solar 370W panels (Model: CS3L-370MS-MC4-F30), which is the maximum I can fit on the south facing roof arranged as a 3x8 array. Roof is being tileds now so need to finalise the design asap to allow panels to be installed. Mains supply is single phase and I have checked with my local network provider that they are OK with me connecting a 9Kw array to the grid. Budget is tight so need the option to add additional batteries at a later stage. Any suggestions on best combo of Hybrid Inverter and storage would be really helpful.
  7. Brochure says ' Corrosion protection - Magnesium rod'. I guess this means it is not a stainless tank and rod acts as an anode? Routine replacement would most likely get overlooked so not such a good idea. But maybe there are other types with a stainless tank.
  8. Has anybody fitted one of the combined DHW and ASHP units? Was at NEC show last week and saw a unit made by Haier - CURV - HP200M3 that seems a neat solution optimised for DHW use. For my set-up the air inlet could be linked to a bathroom and would replace a wall mount extractor fan and allow the unit to recover heat from extracted air as input to DHW as well. It would also allow main ASHP to be smaller and used only for UFH. Any experience good or bad welcome.
  9. Can anybody offer guidance on options for ground floor screed. I was planning to use one of the many self levelling types as final finish will be porcelain tiles. But my builder advises these can’t be laid thicker than 50mm and even that will take ages to dry ready for tiling. So any recommendations for a 75mm layer and I've got about 100m2 to lay. I was planning to do this pretty late in the build after the ceilings have been plastered at least to maintain a neat floor for tiling.
  10. Ended up with the same pipe size as you and yes it is buried in the ground and runs inside house under floor slab. I didn’t use anything special for trench so just relying on the insulation around the pipe.
  11. Thanks for the feedback so I'll try to answer the various questions: For CCTV I've allowed for PoE cameras to various external locations. I was just planning to get a package solution with cameras and recorder to be located in central cabinet from Reolink (or similar) so was assuming this is all self contained for the POE bit. Router (BT or Sky) will also we located inside the cupboard with the cabinet etc. so I've allowed for the option to add WAP to hallway and landing areas to boost the signal. Currently this is just a spare port which ill put near to a socket but I like the idea of using a PoE WAP instead. Do these need to be celling mounted or are there basic units that can go on walls etc.? If I go with PoE WAP idea I assume I need to chose a Switch that supports PoE on some ports. Spec for these units seems very complex to me. So If i need to allow for say 4 PoE WAP devices (and maybe 6 PoE CCTV cameras if my suggestion to use a package is a bad idea) then what size/capacity switch would I need? Some other questions from me: Any recommendations on best places to source patch panels and switches? Any suggestions to help with sizing of cabinet etc. Should this be freestanding or fixed to wall? Is it best to go for more smaller patch panels or a few larger ones? i.e 2 x 24 port or 4 x 12 port panels? Which is easier to connect up? Any recommendations on best type of panels for a newbie to use for DIY set-up? If I've got 40+ Cat6 cables to terminate into a patch panel there is a lot of scope for things to go wrong! Was interested in the Connectix express system as DIY friendly. Seems easier to be able to terminate the cable to a connector when its a loose cable and then mount into panel frame rather than fix cable into the panel when its fixed into the cabinet with maybe limited access to the rear if its mounted to the wall. Any tips on how to label all the cables so it's easy to figure out what came from where?
  12. Thanks for guidance. I've got to the 40+ on the basis of putting 2 x RJ45 ports at least in almost every room, these will all feed to central cabinet and only the ones needed will be patched to a switch. But based on advice for port location I may add more ports in places like the study so have the flexibility to put printers etc. wherever makes sense.
  13. Hi Guys, I'm trying to work out what is the best cable to use to connect the Openreach Fibre supply point that will come directly into the house, with the LAN switch in my media hub. The cable that joins these two together will be about 15 m and I was planning to use just CAT6 throughout the house for all LAN connections. Current plan looking is looking like 40+ LAN points. These wont all be in use at the same time but it seems like I should be running a bigger cable into the media cabinet but not sure what? A second and related question is can a take one of the outputs from the main switch in the media cabinet to be the input to a secondary switch ( e.g in my office) if I need additional ports at some point in the future? Would Cat6 cable be sufficient to connect these two switches together? Sorry i these are dumb questions but this is my first time trying to put in a structured cable network and just want to make sure the right sort of cables go in from he start.
  14. Hi guys, Has anybody used the Kitchens4DIY brand? They have a stand at the NSBRC in Swindon and look to be very competitively priced but again not certain how the build quality stacks up against others. I was going to try Howdens or Ikea as alternatives but I've seen on other threads that the Nolte brand are highly recommended so will be investigating further. Would supply only be an option for Nolte as I understood that German brands usually only come with fitting?
  15. Hi Guys, Has anybody got any experience of using the new type of large format ceramic tiles for a kitchen. I'm trying to find a tile that can be used for complete ground floor area including living areas and kitchen. The current favourites are 900 x 900 x 9mm tiles. Other tiles we've looked at come in more size options (smaller and larger) and are typically 12mm thick but are quite a bit more expensive. Has anybody experience of using these types of tiles in a kitchen space? Would a 9mm tile be too thin to survive the likely knocks and wear and tear without cracking? Would the 12mm be a safer option? Would smaller format tiles be more suited to a kitchen space. Any advice appreciated.
