Aside from getting more Power Walls, another solution would be to break up the solar a bit onto different circuits. For example, you have the entire system on the "house" side of the Powerwall, but if you were to move much of the solar to a different feed point (on the mains side of the...

Yes, absolutely!

Although I would have expected to check it, but is the PV "behind" (on the "house" side of) the Powerwall, or on the "Utility" side? I ask this because if your solar was installed before the Powerwall - and it was connected "before" the main panel (such as a ConnectDER on the meter, if the...

I've seen this sort of thing happen to a solar inverter connected via a rather long cable to the utility connection: When the inverter produced more power, the voltage at the inverter went up, and the system tripped out on over voltage. In that case, the problem was obvious: Excess resistance...

In poking around a bit, it appears that the errors 18xB7 through 18xB9 are reportedly caused by a capacitor failure on the SolarEdge inverter - the number 7-9 apparently identifying something specific in the circuitry. One such place where this is discussed is here...

It's worth noting that a FLIR - or similar - thermal infrared camera is not reliable in determining the actual temperature of any surface that is reflective - particularly at IR - so determining the temperature of the panels with it is problematic. When I measure the temperature of glass - or...

I will concur: I ordered two PW2s in November, 2017 and they were installed in October 2018 and, at the time, I had a single 5kW solar system - which I later upgraded to include another 3.8kW PV system - both series-string SMA. The "addition" of the second SMA simply involved putting the wires...

I noticed that my system just updated to 1.11.2 in the past day or so and I now see on the Android App (V3.2.3) a "Switch to my home" option. If I click this, the circle spins for a while, but I eventually get a "Powerwall Connection Error" that includes the serial number of my PW, making me...

I was going to comment on the spike: Remember that the sample rate of the current monitoring is fairly slow. It is because of this that the system - at least when connected to the grid - cannot respond instantaneously to changes in power, so there are inevitably brief "spikes" when the load...

The Neurio measures both AC voltage and current. If you look closely you'll see that the Neurio monitoring your solar is powered from a breaker somewhere: On my PV system, they installed an entirely new breaker in the sub-panel for that - it not only allows voltage measurement, but power for...

The Neurio that you show in the picture is probably the one used to monitor the production of the PV system - I see what looks like shiny, new hardware on the conduit fitting of the wires on which the Neurio was placed and I'd guess that the circuit breaker is labeled as being for the PV...

A follow-up: Last Thursday (after a week of the PW being offline) they (Solar City/Tesla) were able to schedule time to come out. After one final attempt to get the Nuerio in the garage that monitors the PV system to talk to the GW via wireless failed, it was decided to "hard wire" the two...

It was originally installed in early October.

Last week I got a call from Tesla saying that they needed to replace the Gateway on my Powerwall2 system, citing some issue with a batch of Gateways. Although my GW was working fine and passed their testing, they were directed by Engineering to replace it - a tedious process since they had to...
