It's an option, but more hard work than connecting directly into the access chamber!

Following on from the other topic I just posted, it would really help if I could connect to an access chamber (300mm) the same as in the picture (note it's not this one!) There are no spare inlets, can I create one in the riser somehow? Note that this is surface water, not foul. It would be a connection from an aco drain.

As per the title, is this possible? I've found 110mm hoppers with solvent sockets, but the riser appears to be around 150-160mm diameter. Surely there is a solution short of getting the hole saw out? https://www.toolstation.com/square-hopper-110mm/p71607?store=null&utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gad_source=1&gad_campaignid=21019175163&gbraid=0AAAAAD-vLcXXXI5YTIGEGSG3qJOU7d06k&gclid=CjwKCAiAqprNBhB6EiwAMe3yhghXuo0-GWuBtdc3XxZJyOIMk0tlIYiI_Xj62GxKj9Jw_SYKfFeANhoC7NEQAvD_BwE

I've also used PassivHaus Systems own branded tape and found it very good.

It’s horses for courses really as DC coupled is lower up front cost and slightly more efficient as no need to convert DC to AC and back to DC

I fitted a manual changeover switch to bypass the inverter in the case of the inverter failing, so I can still get power to the circuits fed from the load terminals of the inverter. Also, you’re only considering the maximum load going through the inverter to the load terminals when the grid is down. What about under normal usage with grid connected? There is likely to be a limit that might be the same as when grid is down.

A lot of this foreign made/focused equipment comes with instructions not suitable for the uk imo. EV chargers are another one, although slightly better since the uk regs have stabilised somewhat in the last 4 years or so. Bottom line is you need someone who knows what they are doing to install it.

I'm no roofer either, but I agree with what Nick says. The eaves tray/whatever eaves protection strip has been used should touch the gutter imo. It looks like it stops 20-30mm short, leaving a gap for wind driven rain/splashback from the gutter.

In theory perhaps not, however this is all academic, because that's what the regulations say. You can't leave live conductors connected to the grid when operating a generating set/inverter and you can't make your own neutral - earth link when connected to the grid. In any case, it won't work when connected like this as you'll have parallel neutral paths and any RCD protecting the grid supply to the inverter will trip out as some current will go via the neutral at the RCD and some via the neutral bar. That schematic is a load of %@!$. I'd be interested to hear what Growatt come back to you with!!

If live conductors are left connected to the grid the inverter could backfeed the grid causing unexpected voltages for DNO linesmen. In practice it may well not be a problem if only the neutral was left connected to DNO grid, but that would be against the regulations and have the potential to be dangerous to DNO under certain fault conditions/if the inverter was incorrectly installed.

That schematic is wrong and potentially dangerous in the wrong hands. All 'live' conductors (this includes neutral, don't confuse live with line) must be disconnected from the grid when in island mode. This is a safety issue to protect people working on the DNO side. The schematic shows the neutral from the load connectors connected to a common neutral bar with the grid neutral. This is wrong. Most, if not all, of these inverters are made for foreign markets and the instructions are either nonsense or dangerous when applied here in the UK imo. I would like to imagine that the L&N are both disconnected from the grid entirely when in island mode, but I've not fitted a Growatt before. My Sunsynk does do this.

You won't have an earth-neutral bond once the grid is disconnected from your installation by the inverter in the event of a power cut. DNO earth-neutral bond isn't necessarily at your intake position either. It certainly won't be in a TN-S earthing system (although yours is likely to be TN-C-S (PME) if a new connection).

The same Germany whose economy is f@&£d due to high energy prices, due to idiotic policy?

It’s a bit like giving away Chagos and paying billions to lease it back. Total madness. These people should be removed from their posts immediately for that sort of treasonous behaviour. The only thing that makes sense is the elites wanting to virtue signal on the world stage or personal monetary gain. There’s no other explanation for half this madness.
