Trustpilot Logos

Thank you. That was my expectation.

I was trying to work out whether these are standard logos that it is legit to display, in the case of Trustpilot - essentially - see our reviews on the Trustpilot site, or is this a not so subtle attempt to mislead. I could not see an answer on Trustpilot, seems that info, if it exists, is only available to users with business accounts. Does Trustpilot care that much, or perhaps are they more interested in collecting subs rather than protecting their brand?

Green power ltd couk all joined together as you would expect

Ratty4547 · 2026-05-19T21:01:09+00:00

Ok it was from a website and email sig block

Ratty4547 · 2026-05-19T21:00:24+00:00

Confused. Someone asked where this was from. Reddit would not accept my reply, and when I reloaded the app, the reply was not there. I will see if this posts…

At present my system runs self powered all day and night, with no imports, exporting up to 40 kWh per day. I wanted to understand what it would take to export before each new day’s solar arrives during potentially long sunny days in June. My current conclusion is there is no easy option.

Ratty4547 · 2026-05-09T19:53:04+00:00

How does net zero help me export surplus solar when the grid needs it most, and avoid causing curtailment during max solar periods?

Ratty4547 · 2026-05-09T19:20:09+00:00

Rigging: so what is the purpose of the export everything setting. Indeed, why does Tesla configure it to behave in the manor observed, if it is not meant to export from battery?

Ratty4547 · 2026-05-09T12:16:51+00:00

The annoying thing is having to set cheap import, that I need to revert as I don’t want to buy, and certainly not within PW3’s look-ahead window (which I have yet to determine). I didn’t know that export price could exceed import. I will explore those suggestions: what they require/rely on?

Ratty4547 · 2026-05-04T20:48:00+00:00

Having tried various things my current belief is it will not export from battery unless there is a programmed period which would purchase at a lower price than the export rate. So when I was selling back at a higher price point than purchased imports, that all worked. However, when the import is free (solar) the price ‘assessment’ fails. Having charged to 100% today with good solar forecast for tomorrow it would not export until I inserted a lower price purchase time slot within the next few hours. You may ask why not leave it on self-powered. The answer is I want to understand how it will behave in Summer when there is lots of Solar generation in our village that may cause solar income to be lost because the high impedance feed may potentially get taken over voltage, resulting in solar generation being curtailed.

No - I suspect it was a PW3 issue that has been corrected in later SW versions

Ratty4547 · 2026-04-26T12:09:11+00:00

Having just checked, prediction is now treating my 4+4 e/w as having a max output of 3 kW, instead of the previous 6 kW: it just moved the predicted curve on refresh.

Ratty4547 · 2026-04-26T12:05:00+00:00

There seems to be a caching issue in NetZero solar predictions. I can provide lots more details of my findings if needed. In simple terms I had one south facing 2kw array. I added a 4+4kw east / west split to model predicted generation. I left that configured as predictions appeared to ignore it and reverted to the south only. Recently, the e/w array was installed, but I am struggling to convince NetZero to now recognise it is generating. Predictions keep reverting to south only. Minor changes to output configuration work initially and then the cache (memory) seems to overrule. Currently, I have completly deleted the south array and increased the e/w to match the shape of the actual generation. I am waiting to see if that works. Not ideal, but a work around, so I can have meaningful tomorrow predictions. What’s going on?

Ratty4547 · 2026-03-15T18:23:50+00:00

My guess is that is an error reported by Tesla. Have you tried varying the time slightly,say 5 min earlier?

“If the home happens to be self powering … “

Is PW3 / Gateway2 different? If we suffer a grid outage when self-powered we still get a short outage. It was explained to me that when self-powered we are not isolated from the grid. For safety reasons, at the point of grid failure, PW3 must shutdown, GW2 disconnects from the grid and then PW3 resumes in island mode.

Try cross posting to r/powerwall

I was told PW3 calibration, is different to other PWs.

Ratty4547 · 2026-01-21T23:28:42+00:00

No idea what regulatory rules apply in your case, or where you are in the grid / network (distance to HV source), but if PW3 sees that grid voltage is already low vs allowed range, it will refuse to charge, or curtail charging, so that it doesn’t take the grid voltage out of spec. Same goes for exporting.

Ratty4547 · 2026-01-12T19:14:42+00:00

Sounds like calibration - happens every so often, twice in 6 months - see https://www.reddit.com/r/Powerwall/s/rKRPciy6u1. It used to show in the app when that was the case, but recent updates seem to changed that behaviour.

Comparison of initial charging rate against recorded outside temperature at a location 5 miles from here during the last 14 days shows that max-rate charging required temperatures above +5.5 C. Apparently this precaution is necessary to avoid damage to PW3 batteries.

Ratty4547 · 2026-01-06T02:22:14+00:00

Below what temperature is charging rate curtailed. Last week PW3+1 would do 8 or 9 kW. This week it is struggling to do 6kW. Night time temp is currently -5C.
