I've been so focused on what to buy that I hadn't looked too much at the paperwork etc. I've already ordered part of it and now full of regrets fully expecting that by the time I have negotiated sign off of my installation I'm going to have spent so much money it will never be worth it (especially if the difference between night / day prices get squeezed) lol Guess I'm one of the people that likes the maths to add up!
I have decided most likely on the following
To be honest it does not look like a DIY friendly environment so just wondering what you guys have been doing?
Looks like main points for install are
I have decided most likely on the following
- Sunsynk 8.8kW ECCO Hybrid grid tied limited to <3.68kW by CT
- 15kWh Battery
To be honest it does not look like a DIY friendly environment so just wondering what you guys have been doing?
Looks like main points for install are
- Wiring a new connection to the existing CU (probably 16th edition).
- I considered if I could change the CU to a larger 18th edition and introduce the backup / load connection but it seems this requires a lot of paper work & approval etc. Changing a CU seems like a pointless DIY exercise, assuming you get it certified by a sparky they will basically re do everything and charge double. It is also obviously now notifiable work Part P / BC under penalty of ?
- It seems like a more cost effective solution is to add a 50A RCBO on the unprotected side of the existing CU for the inverter grid connection and connect up with 10mm2 T&E. Pretty sure the CU manufacturer is defunct so it will not be the same company which apparently is another frowny faced endeavor. It looks like the RCBO I have will fit the unit though and align with the busbar which is another PITA sub standard manufacturer specific dumping ground.
- It looks like this is still notifiable Part P work and I'm not really sure how much of a headache that is. If I mount the inverter and cable it then ask a sparky to connect it, will that be sufficient or will they say I need approval to alter anything going into the CU first / after?
- Looking for a DIY friendly sparky sounds like a bit of a contradiction to me. Perhaps I've got the wrong impression but the forums populated by sparks seem to be full of trolls. They all seem very keen on sniffing out DIYers and stating whatever they are proposing is dangerous / illegal / stupid it's one of those protectionist methods of poisoning useful information on the internet & spreading FUD. I've noted it in reverse too, call them out on a bad practice and you'll be told to it's fine even though they just harassed someone they assumed is a DIYer for asking a similar thing. One even specifically stated he would screw over any cheap skate DIYer and charge them double to teach them a lesson. With that kind of attitude I seriously have concerns about asking anyone to even come and estimate for the job. Also I've had a ton of bad experience with shoddy work done by tradespeople in general which doesn't help matters.
- Anyway if anyone with experience knows the best approach to reach a decent sparky that would be appreciated.
- Presumably it is a good idea to notify the DNO?
- G99 A1.1 - I assume this form is OK if I'm planning to limit export but what would I put for the installer...? Sounds like if you are going to fill in DNO paper work you must get an accredited installer otherwise what do you fill in. Maybe I missed what everyone is doing or should I just put down the name of the electrician I get to connect it up even if that isn't totally appropriate. Surely I can't fill in my own details here, accreditation / qualification ... none / something sarcastic.
- I'd consider hiring someone to do the install, presumably would have to be a sparky anyway but I'd consider setup of the inverter to be my domain. Got the impression there aren't going to be any DIY friendly options here either or maybe I don't know where to look?
