Yes. Ideally, not Cyberpowers, as their accepted frequency range is too narrow. Look for an Eaton UPS, which has an upper frequency range to 70Hz and will not have any issues with the PW raising to 65 Hz.

Seriously - the Ubiquiti gear is good, and I use them too, but I would NOT recommend them to provide comms to a PW2 gateway. In fact, to get a reliable connection, I had to fire up a legacy dumb access point on a different SSID just for the PW2, while running the rest of the house on Ubiquiti...

Fairly common - many homes get upgraded to 3-phase to service a new higher power aircon system, or (shudder) swimming pool heater, if its not done with gas. Lately, some large induction cooktops recommend the house being connected to a 3-phase supply, if only so the cooktop can be on one phase...

I'm not sure I understand the problem. If you are off-grid (the grid has been disconnected/failed) and the battery is full, then the solar inverters can't produce any more energy than your house is using at that instant. Sure, if you turn on a pile of things and make more load, your solar can...

I don't know when mine updated to 1.44.4 - only in the last day or two. It seems they've fixed the charging priority - 1.43 used to send a lot of excess solar out to grid early in the day, despite the battery being less than 30% and needing some charge. It would then switch to finally directing...

After a year-and-a-half, and correcting for the current SOC of 1.8 kWh stored, my stats are "energy_exported": 6319520, "energy_imported": 7035558.2, efficiency 89.82% (close enough to 90% for my purposes).

Note its not "either/or" - the PW2 gateway can be simultaneously connected via WiFi and hard-wired cable to your home LAN, AND through their internal 3G gateway to the cellphone network - up to all three simultaneously. It will use whichever provides the best connectivity at any moment to upload...

Mine went one better - installed a new LAN cable through the ceiling cavity to connect the Tigo optimiser control box to - which is mounted nestled within 1 foot of both the inverter and the PW2 gateway that both connect fine on WiFi. They installed the PW2 and inverter first, so they knew the...

Mine always locks on to the channel that the basestation SSID is being broadcast on - whichever channel number this is, it switches the internal 'TEG-XXX" SSID to the same channel. If something is changing to stupid channels, are you sure its not the gateway simply responding to your basestation...

It IS possible - our powerwalls in Australia, and several other jurisdictions, are allowed to and do exactly this. It is administratively disabled in many USA territories, for reasons, possibly only USA-specific-tax-reasons.

FWIW, we don't have 1:1 net metering either. In fact, when I called the Tesla hotline (through to the US-based callcentre) and asked about the two TOU modes when they were first brought out, her response was 'You're in Australia? ah, probably those TOU modes won't make sense, since they are...

FWIW, I think I've figured out what the algorithm is trying to do in the morning. Overnight, between midnight and whenever the sun rises around 7am-ish, the system runs the house on some mixture of battery and grid. (you can argue that during off-peak it shoudn't ever draw from battery, but...

Yeah - Nah. There's plenty of PW2 batteries installed in Australia, and many other brands of batteries, and they work fine during power outages. Its perfectly possible and legal and common practice to have batteries back up the mains, just like most other countries. Its not dangerous, the...

No - they're installed in NZ, and throughout Asia, often as power backup for cellphone towers - and lately in South Africa also. Theres a list of international partners at the bottom of Redflow – Sustainable Energy Storage, if you get in contact I'm sure they'll be only too happy to tell you who...
