Cyclone Alfred: What to do with your solar and battery

As everyone will know, Cyclone Alfred wears some rather populated parts of Queensland and New South Wales. Solar installers have published useful links. Without expanding the information overload, we would like to insert some of the best tips we found together.

If you have connected a standard network

Energy gives a covering advice to switch off your solar power. It is really not necessary and it is really angry in the installation program industry in Brisbane, because the phone simply does not stop ringing.

AS4777 stipulates that when the power supply ends, also your inverter. It is not important to switch off solar systems.

Unless your system has an insulator on the roof (for which nobody should search for a wind in 100 km/h), which switches the DC on the inverter, really does not achieve anything. By separating the safety functions for the earth in the inverter, the system makes it less safe

Quote from Brisbane Solar repairs; Your inverter is a very clever piece of machine – it can recognize when the power supply fails or the network has become unstable and switches off from you without intervention.

First switch off the air conditioning; Then the DC

If it makes it more convenient, you can of course complete the system as a precaution.

It can be worthwhile if there are probably lightning strikes, electricity poles or trees.

In any of these scenarios, you could have fed a monumental tension over your street. Trees can drop feeders and cross them with the 230 volt Street distribution system, which leads to a continued injection of 11,000 volts, while a flash can be more million more volts.

However, the general council is that a battery -operated radio is set to ABC Local and some ice is inserted into the freezer to transfer into the fridge when the electricity fails.

This triggered a storm full of unnecessary fear and unnecessary phone calls

Energy may have reasons to tell people that they should switch off solar, but they don’t explain them properly.

With temporary HV generators or Piggyback network -Feeder, which are provided as stop gaps, if you try to put things back into operation, network stability can be difficult.

However, the explicit instruction of Energyx for people with batteries to switch off DC Solar for “security reasons” is simply wrong.

If you have a battery

Fortunately, it is worth testing the blackout function (provided you have activated this option for installation) by switching off the power supply.

A “main switch” or “main switch supply” or possibly “meter insolator” should be present in their main tablet, and this should be a different label for the rest.

If you switch off the offer from the street, a failure simulates so that the lights remain switched on depending on the system, or it can take up to 40 seconds to get back, accompanied by a knock from the switching board.

Batteries may need administration

Many thanks to Scott Su at Sungrow, who was proactive on social media to explain how you can make sure you have a complete battery before the network drops.

Follow the red highlights to navigate the app and make sure that your battery is fully charged, or try the YouTube manual here.

  • First find the account for your installation or property

(This is an administrator screenshot, so that you may not encounter this view of your consumer monitoring.)

  • Note that the apps can vary with the age and installed hardware
    • Scott says you choose “menu” to expand the technical settings
    • In my own sun woman app I have to select “device” to get to the next screen
      (where it says in this picture “dashboard”)

Standard three bars for the menu

  • Select the “Hybrid inverter” oR “energy storage system”

Your system may be listed more than 1 inverter.

  • Slide the upper bar via the “Settings” tab and then tap on “General Settings”.

There are many settings, consult your installer or possibly your YouTube if you have doubts.

  • Set your battery reserve to 100% so that it is fully charged, unless the network will be missing
    • Ie “please enter 100”

The security mode should already be activated if the house was of course wired for this.

This is a good example of the process, but SungRow promises us to work on a more user -friendly switch on the start screen to make it much easier.

If you have another brand of solar hardware, surveillance will of course look different and there will be another procedure.

For example, Tesla has an option called “Stormwatch”, which is designed in such a way that this battery is automatically noticed. However, if you are via other controls such as a retail contract with AMBER or part of a virtual power plant, these may have to be deactivated so that you have complete control over the battery.

When she wades out of a house that goes down

Nobody makes this situation light, but the inimitable John Ingliss of Voming’s own Positerian solar has a very helpful video that is posted on YouTube.

Remember this is the pragmatic advice for competent people. The authorities would consider it for electrical work that should be legally carried out by trained electricians. Since these qualified people are scarce in an emergency, you can take these tasks at your own risk.

In this video, he outlines how you can deliberately short-circuit your DC solar energy and make it safe by clamping the tension to zero.

The use of a clear path for circulation of electricity is actually a security feature that some inverter manufacturers like SMA uses to deal with potential earth errors.

This is pretty certain because the cabling for DC Solar Arrays is drastically oversized to minimize the losses. Sun collectors are a currently limited source, so that it simply does not overheat the wiring, which has tripled the workload for double or tripled.

Separating the source of alternating current is not a guarantee, but it means that the likelihood is less likely to be damaged if it has some moisture occurrence. The separation of the DC prevents the possibility of an inner inverter fire in the hours and days after the water decline.

However, there is an important restriction

  • Since this video was recorded, most solar inverters have moved to a DC insolator on board in the inverter.
  • If you want to make the array short for one of these modern units, it is best to do the work at night as it will be the DC solar plugs live If you try to remove them from the inverter and connect them.
  • Separating or fumbling with living plugs causes a considerable DC arch flash, blackens and melts the pens and may burn your fingers and sings her eyebrows.
  • If you have any doubts, let yourself be easy to do, it is not worth taking the risk.

Energy has advice; Not everything is good

If you go to your website, there are some general precautions in a PDF and a website with rather solid arguments.

However, the general advice on processing solar power systems published on social media on social media causes unnecessary fear, uncertainty and doubt.

The message to take away is:

  1. Treat solar power systems and components with respect, especially if you may have been flooded with water.
  2. If you have a power supply system that is probably flooded, you will receive professional help to move components and the array too short.
  3. Let your system inspect and recommend by a qualified installer after the weather has expired.

The small print in their network connection contract contains a regular inspection of an electrician, usually at intervals of no more than 5 years. So take the opportunity and make sure that everything is good for the coming season.

I will only make myself worse

Although it has passed 35 years between the drinks, it is not unprecedented that cyclones after New South Wales have an impact, but according to the insurance industry, it is the excessive precipitation and the resulting floods that prove to be most harmful.

When we catch more energy in the climate system with a carbon ceiling in the atmosphere, extremes of the weather like this storm become more frequent and stronger. There is no debate, it is not about believing in climate change, the insurers repeatedly put their hands on state subsidies.

Regardless of whether you are in Alfred’s line of fire this time, it is worth dealing with your solar and battery system when a strong storm is to do because it is becoming increasingly likely that you do it.

I just hope that these, who also complain about the AFL season start, had to be canceled to pay attention. If football is affected, this gets serious.
