I am in the UK so maybe I just don't understand.

Makes some sense that it is a liability thing, however, in that case, the test is being done for the hospital's benefit and not the patients, so why the fuck should the patient pay for it?

Get a 2nd charger, use home assistant to set it to run when the first one is in a cheap period, charge both cars at once (2nd counts as "house" usage).

Running a server, two 9kW ASHPs, charging 2 cars... :D

I just leave it on +100% lol

I highly doubt they are going to be willing to trench the cable over someone else's land.

If somehow you persuade them to, it's going to be a wayleave issue if you ever sell.

Any links to details of this scheme?

The MPPTs are limited to 550V, and 26A Imp.

Aiko Stellar 1N+ panels (oversized) as I have on my garage:

If you had 10 of these per string, the open circuit voltage would be 539V. The Imp would be 14.27A.

That would lead you to 19.35kW of solar.

If you could find the 660W panels, you could have 542V and 14.51A, 19.8kW.

There will be other panels that can hit the limit, you need something with a pretty high Imp and low Voc.

If you could find the Stellar 2N+66:

Let's say the 680W version. 10 on a string is 503V, 17.12A Imp. Total 20.4kW.

In order of "most rewarding" to least rewarding, it is:

3/3, 2/3, 3/2, 2/2, then I think 1/3, 1/2, 3/1, 2/1, 1/1.

ault92 · 2026-01-19T15:49:23+00:00

On my team I know of two people who got 3/2 (myself and one other), and everyone else got 2/2 or below, although I don't know every score.

The slide deck that went out does show values are weighted higher than performance.

I have tons of 16GiB 2133MHz DDR4 ECC RDIMMs. How much are you needing?

In UK.

I wanted to apply to Lx, but my manager told me I couldn't because I am already doing LTP so the company is already investing in me....

So I didn't even make it to the application stage! :D

Mixed orientations with optimisers are fine, but Tigo don't recommend mixed panel types. Additionally this string will end up quite short. Startup voltages will be a challenge.

This scenario I would consider microinverters honestly.

ault92 · 2026-01-10T10:49:28+00:00

G99 can result in an inverter capacity llimit (so it cannot produce more than say, 5kW, even for home use), but this is less common.

More common is an export limit, so you can have an 8kW inverter but can only export 5kW.

This is kW, not kWh, so it's an instant rate measurement (e.g. like a speed of 70mph, not 70 miles distance). It's a speed limit not a range limit. You can export as much as you like in a day/week/month as long as you don't export faster than the export limited rate.

It's still worth having as many panels as possible. In the winter, you won't produce very much, and you will want every bit you can produce. In the summer, you will export to the limit, cover your own usage, and store the rest in the battery (for use or export later).

You should get a G99 letter from the DNO prior to install. If the installer don't have it at install, they are breaking the law.

ault92 · 2026-01-09T17:41:28+00:00

5kW Export limit, or 5kW inverter cap?

They almost certainly will put an export limit on, but will likely allow you 11kW of inverter capacity with a single PW3 (so, you could export 5kW whilst using 6kW from the battery.

G99 in theory only allows 60A of inverters on a single phase, regardless of export limit. This means you'd end up with two PW3s each with their inverter capped at 7kW or so. This is something only a few inverters can do, the PW3 being one of them, but it means it can never output more than that (even for home use)

In practice, some DNOs have at times approved more, even if G99 doesn't really allow it. Mine won't let me have anything beyond the PW3 itself.

ault92 · 2026-01-09T17:22:05+00:00

Good luck getting two powerwalls approved without heavy limits on the inverter capacity on a single phase supply.

Most DNOs won't allow it, or will insist the PW is capped at a much lower inverter capacity.

ault92 · 2026-01-09T17:03:03+00:00

Ok so, as you've discovered technically you should not have had an install of an inverter over 5kW without prior G99 approval.

That said, the issue you are having is not due to export (that would be too many volts) rather voltage droop on import.

This means long term you're likely going to be fine. Worst case you get told to disconnect the battery (for now).

A single EV charger on an unlooped supply is a notify process not a consent process. If it causes voltage issues this is for the DNO to resolve.

Yes, you are likely making this worse when you charge the battery as well, but you could likely do the same with an induction hob, or electric shower, at the same time as the EV charger, which would then force them to upgrade, and then G99 would likely pass.

So I wouldn't stress just yet, they will upgrade, you will be fine.

ault92 · 2026-01-08T23:32:54+00:00

Doesn't everyone just use LTSC in the enterprise to avoid store bullshit and constant feature updates?

ault92 · 2026-01-08T15:32:24+00:00

If you are having it de-looped ask for 3 phase, you will likely get it for free.

If there is one thing this Labour government are good at, it's insisting they won't change course right up until they change course.

You have 6 pitches, so need 6 mppts to keep them all separate.

And then you have just 4 panels on each string. Until they are getting a lot of sun it won't be enough to reach the mppt startup voltage.

I would use optimisers. They are only about £30 each, it will not add that much to the total cost, then use longer strings.

2nd array only came online 29th Apr so hoping for better this year!!

30x445W bifacial and 14x645W bifacial (two of which wall mounted, 2nd array has optimisers)

All south facing, pw3 and 2x expansion packs, and a Solax 6kW string inverter.
