    Tesla: we need more control over our PowerWalls

    Sadly all my contacts at Tesla UK no longer appear to there (emails to them now bounce). I still have the export setting on the GW as a legacy from TEP. I'm currently sticking to Self-Powered as the Time-Based control draws ~4kWh/day whereas Self-Powered only 'leaks' about 1kWh/day. It is...

    Tesla: we need more control over our PowerWalls

    I do hope the request to be able to discharge a PW to grid doesn't die again. I have a connection agreement that permits me to export at 40kW. What I would dearly like to do is fill the 4xPWs from solar (Currently they are full be 10:00 a.m.) and then discharge a proportion e.g. 40% to the grid...

    2x Powerwall on 2-phase UK supply: sensing PW SOC individually

    I have no issue with one phase on a 180 degree split phase (230v - 0 - 230v) supply not being backed up. It is whether the GW2 will function correctly with 2xPW/2 on the backed up (house load phase) and 1xPW/2 on the non-backed up phase (workshop so the PW/2 here is just to improve...

    2x Powerwall on 2-phase UK supply: sensing PW SOC individually

    I have a written reply from Agile Phil (Octopus) that they can supply a Polyphase SMETS2 meter which function as a two phase vector sum meter on a 180 degree split phase supply.

    2x Powerwall on 2-phase UK supply: sensing PW SOC individually

    Simply down to cost. We are currently limited to 23kW gen / 17kW export on a single phase supply. To expand our capacity WPD offered split phase for £6k (48 kW gen / 40kW export) but three phase would require a replacement PMT and a second 11kV conductor back to the substation and would cost...

    2x Powerwall on 2-phase UK supply: sensing PW SOC individually

    @TyneTes I would be very interested in your experience of a split phase supply and a gateway2. We currently have a number of PW2 and a GW2 on a single phase supply but have reached the DNO prescribed generation limit. The solution being offered by WPD is a second supply 180 degrees out of phase...

    Is there a log of the Powerwall Battery Percentage?

    I just pull it every few minutes from the gateway using a simple PS script and plot it out. The anomaly on Friday was that I only check for token expired and that was the day Tesla decided to downgrade the firmware resulting in an unexpected response until I manually created a new token. (Yes I...

    Software Version 20.49.x

    For those that use Powershell to read local stats from the GW, post 20.49.0 this works: Powershell 7.1 example: Authenticating is simple: $postParams = @{"username"="customer";"email"="PW Customer email address";"password"="PW Customer password"} $tokens = Invoke-WebRequest -Uri https://your...

    UK Only - Tesla Energy Plan/Octopus Energy

    Yes, I have started to see small exports around breakfast time but it is still whacking it up to 100% from the grid most mornings and going on to export most of the PV around the middle of the day as the batteries is full by then. If it goes on like this I'll have three EOL PW2s well before...

    UK Only - Tesla Energy Plan/Octopus Energy

    I have been on the Octopus Tesla Lite tariff for a couple of months now and am in two minds about it. Apart from a cock up where WPD swapped over the MPAN# and my use was showing as export for a few weeks it seems to be working as expected. It does hammer the batteries. There is no benefit in...

    Beware SMETS2 meters

    After the faulty L&G smart meter was replaced my half hour readings are showing 0 kWh import instead of a steady 0.03kWh / 30 minutes One very happy customer (of Tesla and Octopus). Octopus have offered a compensation package which is slightly higher than I had calculated so the excess will go...

    Beware SMETS2 meters

    Yup Kaifa MA120 arrived yesterday. The display implies that it also functions as a CAD but after send an enquiry to Chameleon Technology it appears that enabling wi-fi just uploads your usage data to their cloud to use as they like. So now the search is on for a SMETS2 CAD that can be configured...

    Beware SMETS2 meters

    Meter change tomorrow 08:00. I'm hoping it is another L&G meter as it took ages to find out how to pull data from the E470. I assume switching manufacturer will push me back to square one on that front. Has anyone already had an Octopus meter replacement and knows which one they are replacing...

    Beware SMETS2 meters

    Their reply this afternoon said they had had a sudden influx on this issue. They seem to have forgotten that I emailed them a year ago about these two issues - 1) this E470 was incorrectly recording use in the wrong time period i.e. I was drawing 20kW one minute after off-peak started and 4...

    Beware SMETS2 meters

    I received the email. I had already contacted Octopus about the timing issues with the L&G E470 but thought I should re-register this complaint. I was told, after they had a discussion with their 'metering dept.', that they had not received any similar complaints - which is surprising.
