Whenever a major power outage occurs, interest in solar and batteries will increase.

The recent hail, heavy rain, lightning and squalls have once again swept across the country; leaving hundreds of thousands of homes and businesses without electricity from the main grid-and some longer.

During these power outages, many solar owners will also lose power. The reason is related to safety.

Traditional solar inverters have a necessary function called "anti-islanding", which can detect power loss from the grid and automatically shut down the inverter. This is to protect workers who are trying to restore power. If the power continues to be exported to the grid while repairs are being carried out, this will pose a threat of electric shock to infrastructure workers. It may also cause further damage to the infrastructure.

But as solar technology becomes more and more intelligent, there will be more options to obtain backup power from solar energy during power outages—no batteries required. "Grid forming" inverters can safely isolate the system from the main grid during a power outage and enable solar panels to continue to supply power to the home. One of the products is the Enphase IQ8 micro-inverter, which is expected to be launched in Australia in the first half of next year.

This is great for having some power during the day, but during solar power generation and particularly unfavorable daytime conditions at night, batteries (or generators) are needed-and during power outages, not all batteries have backup power.

Installing solar battery storage does not necessarily mean that you will have backup power in the event of a power outage or extended event.

Many battery systems currently available in Australia either use battery backup as an optional additional feature or do not provide this feature at all. On the SolarQuotes solar cell comparison table, follow the "Off-grid capability" row to view models that can provide backup power during a power outage event.

In addition, when the grid is off, under normal use, most batteries will not power your entire house. This is because the power requirements of using multiple energy-consuming devices at the same time can overload the battery.

For example, Tesla Powerwall has a 7kW peak/5kW continuous power output rating. When using a traditional oven, while the kettle and dishwasher exceed its capabilities, the Powerwall will shut down.

But it's not just about power; the energy (differences) requirements of certain appliances can cause batteries to run out quickly.

This is why it is necessary to decide which circuits to back up when installing a battery-usually just the power supply for critical loads such as refrigerators, lighting and small appliances.

In addition, depending on the system, it may not be possible to use rooftop solar panels to charge the battery during a power outage. Therefore, anything in your battery may be what you have until the main power is restored.

If it is important to you to have a backup power source in the event of a power outage, make sure you are very aware of this requirement when choosing a solar battery. If you are looking for an installer who really understands home energy storage equipment, SolarQuotes can help.

Michael discovered solar problems after purchasing modules in 2008 to piece together a small off-grid photovoltaic system. Since then, he has been covering Australian and international solar energy news.

Like the situation in 2018, does the Apocalypse prove that the three-stage housing is still very expensive?

Although I think that given the current price, it will not happen in about ten years, but I suspect that in the long run, I will look for an off-grid compatible battery system, or completely off-grid, and depending on the decision regarding usage fees and supply charges The severity of the rise. In the past few years, supply costs have risen by 20%. Usage costs seem to be stable-although it is difficult to compare across plans over time, of course, FiT is falling rapidly-by about 30% in less than a year. As costs rise and solar revenue plummets, the equation for purchasing electricity and returning batteries has changed.

Are you not sure that the cost of supply will increase by 20%? ?

For my Endeavor Energy area, the historical price is: (for ToU)

2014-15 56.34c/day 2015-16 49.72c/day 2016-17 50.41c/day 2017-18 55.33c/day 2018-19 39c/day 2019-20 40.21201c/day

These prices can be found on the AER website.

It seems that Endeavour has reduced its ToU daily supply cost by 26% from the 7-year price in 2014-2015.

Of course, what the retail market does with daily supply costs is a whole new game. Therefore, it seems that my dealers are fair, and the retail market must share the responsibility of raising daily supply costs.

When these prices were disclosed, all of these ramblings about dealers' price increases were unfounded.

FiT is directly related to the wholesale price, and the distributor cannot do anything about it because it is a distributor, not a generator or a retailer. The retailer will decide what to pay for FiT because it replaces the retailer's price already paid to a large generator NEM wholesale price. Only the beans counter of the retailer can calculate the cost that the retailer is prepared to pay for FiT when calculating its operating costs and purchasing power from NEM.

I found that even if there are 60 retailers in the same distribution network in my area, usage fees vary greatly. The usage fee is very unstable and will change every month when looking at the plan.

I found that the cheapest off-peak ToU is 11c/kWh (not to be confused with controlled load) and it is provided during the day (not just at night). The highest peak electricity price I found was 39.5c/kWh. With other people. When the electronic source comes from the same place, how can 60 different retailers offer such different prices? My local street transformer is connected to the local substation (no generator nearby). The local area substation is connected to the nearest area substation (no generators nearby). The local community substation will be connected to a power transmission switch station not far away (there is still no generator nearby). The nearest generator is about 100 kilometers because the crow flies from where I am. Even so, I don't know if that generator is providing me with electronics, depending on how the network switch occurs where demand and supply can adapt. You can't force an electron to get cheap electricity from the grid from the cheapest generator to your home. (Unless it comes directly from a person's photovoltaic system). If there are some magical ways to mark electrons, it is cheaper, that will greatly change the market, but it can't do it... Everyone wants electrons to be marked as coming from solar or wind farms! Dirty electronics in coal will be avoided as much as possible. I want to know whether those who love coal are willing to buy dirty electronics at a higher price, just to maintain their beloved creed of keeping the FF industry alive.

The electricity price we pay is obviously to blame on the retail market. Get rid of the retail market and allow distributors to restore direct sales to consumers.
