Don't know about other systems (and will be glad if anybody else share some info about their systems), but in case of solax I have, you cannot monitor it locally - system sends all the data to China, and you can access it via web browser or mobile app. It works, but sometimes painfully slowly.

Really liked not burning anything for half the year. Now that there’s 5 of us it just couldn’t keep up and we ended up using the boiler for a top up most days. Now we have a 400L cylinder with the thermal and new PV feeding it. I know there’s an argument for whether the price per kw from oil makes the diverter worthwhile but if we can get back to 6 months of free hot water I’ll be pretty happy
rob w wrote: » Hi, Maybe this is the wrong thread for this post, if so mods can move it. Just wondering about anyone who has done a DIY install, or through a REC rather than a registered SEAI contractor (as quotes I'm getting with grants are very high). The ESB NC6 form requests the 'type test forms' to be submitted with the application. Does anyone know where these can be sourced from, I presume they are supplied by manufacturer along with purchase or how are they obtained? Thanks

rob w wrote: » Yeah but can't a registered electrical contractor do the sign off, it will just not meet the SEAI requirements for the grant then?
spose wrote: » I did same. DIY on all except connections. It was only going on a shed so wasn’t too worried about impacting the integrity of the roof. Was doing an extension anyway and electrician did it as an extra. No issues with not having seai registered installers name on the nc6 form just reci needed. Obviously couldn’t claim the grant which would have helped a lot since we were skint from the extension anyway. For me I just couldn’t justify the extra cost in going with an installer. The report for the nc6 came from the wholesaler I bought the gear from.

Shefwedfan wrote: » Wow that would be impressive....I would question him and confirm how he knows that would happen My house is a C1, I very much doubt with Solar I will jump to a B1.....I would be happy to get into the B’s at all Now maybe he is correct if house is down low like an E or something and it would jump to D I’m no expert but if jumping was that easy then happy days

unkel wrote: » Try negotiate that down a bit more. Even if you couldn't, the pay back on the bigger system without the Eddi will be quicker (provided we get a FIT, even a low one, at some point in the next 5 years or so) And like I told you before, with or without an Eddi, with or without a FIT, with or without a battery, getting excess PV into one of your cars via the Zappi that you have already installed, is the most profitable use of your PV after the direct use of electricity in your house
rob w wrote: » That's great, thanks for the info. Exactly what I was after. I'll make sure I can get the certs from wholesaler before buying if I go down that route. Just wanted to be sure too there was no hassle with using a REC (as opposed to one registered on SEAI list) for sending in the application. Might send you a PM with a few more questions on your install if you don't mind? Dont want to derail this thread any more! Thanks
Shefwedfan wrote: » For those that have system installed. Do they come with a standard system that allows you to monitor SolarPV generated etc? or do you need to invest in something additional?
worlds goodest teecher wrote: » Well he didn't specifically say that, he said that you could expect to move up a letter, the house we were discussing currently has an E rating. Will be pumping cavity plus adding 200mm insulation to the attic before I look at solar. I'm aware of the min C rating post PV installation required for grant.

worlds goodest teecher wrote: » I would be starting off at a E1. List of priorities: 1. Pump cavity 2. Adding 200mm insulation to ceiling 3. Draft strip windows 4. Composite doors front and back 5. Replace open fire with pellet stove 6. Install 4kW solar PC system with battery 7. Replace 20yr old oil boiler with a more efficient oil boiler. Wonder what the min size boiler I could get away with after all that.

wexfordman2 wrote: » Its b1 now, cant remember what It was initially, the bits were done over a few years so it was a gradual increase. The solar was the last but, and I think it took me from c to b1, will dig out the carts and see if I can get more info
wexfordman2 wrote: » Ok, so the first job we got completed with a BER was when the boiler got upgraded, and we were C3 after that. We then got walls pumped and attic insulation improved, which brought us to c1. We got the front door replaced from a timber one to a composite one, but no BER was done based on that work. The solar Pv install then brought us to b1 (vant find the ber for that, but am sure it was b1, as I was a bit disappointed hoping to jump to maybe an A3.
