If you have 1:1 net metering you have a virtual battery at 100% efficiency, infinite size, and zero cost. What was the question again? Now you know why the power companies don’t like it.

Baby steps: 1AWG wire on order, those GoodWe grid-tie inverters are getting swapped for a pair of 18Kpvs

So buy the panels now, and if you don’t move in three months, they will be more valuable and you can sell them for a profit.

Everyone disconnected their antennas so it wouldn’t blow up their radios. 🤓

Still, it’s all about the pricing. Dollars per installed kilowatt hour, dollars per kilowatt hour, stored and released, those are the things that we care about.

See if traceroute shows a routing loop somewhere, that’s what usually causes this kind of thing.

Shiny! Specs and prices, please! 🍿

Our Kona has a more agressive Nanny, but it’s saved my bacon in FL a couple of times as parking lot race cars cut across my stern as I’m backing out of a spot. But that’s FL, I used to think MA drivers were the worst, then I moved to FL. 🙈

No-one can because it’s not that easy balancing all the factors (range, power, size, mass, cost), and the US consumer has proven over and over again that ’size matters’, and it’s the Suburban Assault Vehicles that sell, while the $25K EVs are either never produced (looking at you, Tesla) or sit...

Or having tax rebates for the above. 🤷‍♂️ None of this stuff has a single solution, and everything’s chaotic enough that the unintended consequences push the results even further from what the originators (said they) wanted. We’re going to have tariffs and rebates and incentives and job...

Wall Street Journal: /* Beyond raising tariffs on electric vehicles, the White House announced on Tuesday that Biden is increasing a key tariff rate on steel and aluminum products to 25% from 7.5%, while the tariff on solar cells will rise to 50% from 25% and a new duty on shipping cranes will...

We still need specs on your panels, inverter, and central air system, but this probably isn’t going to work. Look at mini-splits instead, ours run betwee 200-500 watts average and do not have the startup surge that older, non-inverter central systems do. Can you swap out your central system...

We call the windows “Rain Preventers”. If you close them it will never rain. Leave them open on a clear day and it’ll pour.

Works fine from the Turks and Caicos, are you sure your ISP isn’t blocking certain traffic to the states?

Sorry, I don’t know what that means

Our PoCo wanted to give us avoided fuel cost before my AHJ nerfed net metering completely, so off-grid with batteries and controlled grid purchase through ChargeVerters it is. Not a bad idea, I keep getting emails from my monitoring system along the lines of: /* Grid Frequency is 54.7 Hz at...

It bypasses the need for the WiFi password. If you’ve set a local password for the UI then you’ll need to know that.

At the end of the day it’s the consumer. While the supplier might cut their margin to balance the old supply/demand curve, they are not going to take a permanent loss.

Looks like when the sun comes up and the panels start producing power, but again if the settings don’t match the physical configuration then I’m not surprised “weird stuff happens”

This. Even with batteries it’s useful to spread the stress on your equipment out over the day.

This. Everything is Opportunity Cost.

That doesn’t say “Trip by AC”, it says “Trip by NO AC”. You seem to have told it you have batteries but then not connected the batteries, so I’m not surprised it’s confused. How is your inverter connected to the grid and the house and the PV?

So you are grid-tied and the grid goes out of spec?

If you only have to visit your roof once, that’s a big win. Put up as many panels as you can in one go and bring each string back to the inverters separately in case you need to test or reconfigure without making a roof visit.

If it’s a port on the inverter that wants to talk to batteries it’s almost certainly going to be the bus master, so your solution would have to eavesdrop on the inverter->BMS communication and hope the data you are looking for is in there. Alternatively you could do a man-in-the-middle...

Typically RS485 is labelled as A/B or +/-, and RS232 is labelled as Tx/Rx, so you first need to figure out what you have.

Well then both sides have a self-assigned address, figure out what your laptop got and do a network scan for the Pi. Or hook it and your laptop up to a router and ask the router what IP the Pi got

I’m going to say no, though the fiction writers and doomsayers don’t find any interest in that. Not that significant grid disruptions wouldn’t put a big dent in so-called “civilization”

Thank you for this, it finally makes sense!

I keep hearing this, but every high tension power line I’ve ever seen has individual strands running in parallel next to each other from tower to tower. Twisting the individual aluminum current-carrying strands around the steel strength member won’t cancel the voltage in that one strand.

What’s the network on the Ethernet you plugged into it, and what DHCP address did it get from that network?

So exactly what is Edition 3? EG4 ESS has had UL9540 for a while now…

Yes, the Ethernet user interface is identical to the WiFi one, in fact they are just the network UI.

As always, if you ask a question of the Internet, it will respond with yes and no and maybe. First of all the hundred percent tariff is for electric vehicles, as far as we know batteries will not have 100% tariff. Second of all while the announcement is due on Tuesday, we don’t know when the...

There seems to be some confusion as to whether we want Grade A EVE cells with traceable provenance, or we want paperwork that says the same thing but at a lower price (or a higher markup for some middleman). The middlemen don’t care, they’ll sell you what looks like what you want. If it’s...
