Solar PV Hints, Tips & Troubleshooting

I got a copy of the email confirmation from ESB to my installer. I got nothing from EBS directly. That was 8 months ago (installer was 2 months late submitting it until I asked to see a copy of the ESB confirmation).

The heatpump is more efficient as there is a COP multiplier. 1 unit of electricity gives more than 1 unit of heat.

A diverter only feeds the immersion so it's a 1 to 1 ratio of electricity to heat. Meaning it's lower efficiency than the option above. Scrap the diverter and spend the money on more panels instead. We get paid ~20c a kWh that is sent back to the grid (once you're a smart meter), so you're better off getting the credit. The hot water diverter will never break even.

In the months when solar output is low, you can get use the cheap night rate and heat the hot water from the heatpump then. Assuming it's a well insulated tank that won't lose much heat during the day.

Does anyone know how I can check the grant process?

My BER report was delayed due to the BER inspector having a baby so it was only done 1.5 month after initial installation. The installation was done 20th Jan, BER issues 4th April. I checked the only application and can see that all documentation has been uploaded from the installer 26 days ago.

There is no real way to check status. I have basically 1.5 more months before the grant application expires. Any idea how I can check if there are issues etc.. with it? There seem to be no contact form anywhere on the application portal.

Thanks, I reached out to SEAI using their contact page. Let's see what happens, :) I will update when i get any response.

It will heat the coil in the cylinder and create a small amount of circulation. How far from the cylinder are you seeing it? Any chance a pipe stat on a circulation pump is closing?

I'm feeling both pipes in the hot press and the return pipe is warmer than the feed. Feed is luke warm and the return is reasonably warm. My pump is actually in my pellet stove boiler. I don't have a pump at my hwc. Tank is about 12 metres from the stove, the pipes are going up from the hwc across the attic and down the back of the stove.

I'm getting hint alarm every day in the fine weather for grid over voltage.

Nothing happens apart from the notification on the phone.

Should I be bothered about this, and is there a way of stopping it?

Unlikely the panels.....

Did you look at the telemetry for what the grid voltage is over a period of (say) 48 hrs ? Something like...

Basically in Ireland the grid voltage is allowered to be 230 +/- 10%, so as low as 208v and as high as 253v. If your hitting 254v it doesn't mean that things will suddenlt start going BANG(tm), but it does indicate that the supply your getting is technically not within service level agreement. This normally happens when you are close (or perhaps) the 1st house nearest to the substation/transformer.

If it's an issue, you can in theory get ESB to fix it. Takes a few hoops I believe. Someone on the forums did this 12-18 months ago and got their over voltage fixed.

AFAIK, the newer EN50549 Standard now permits +/- 15%

255 seemed to be the highest yesterday

I think you can pick any. Maybe go with NL

Yes that was the first thing I had to do. Change the standard due to constant over voltage alarms. We are rural so during the day the voltage ranges from 210 to 255 or higher. Depending on what farmer is doing what, I guess.

My myenergi app is showing the same readings the last few days. Anybody know how to do a reset please?

I've seen the answer posted before but can't find it?

Here is ESB Micro and they look about right so have changed to this see what happens..
