Solar Batteries In Perth

Powerful & Reliable Solar Batteries In Perth

Perth Solar Batteries are the number one inquiry we get from old and new customers alike. Reliable battery technology is here, but unlike our Solar systems that have very short payback periods and last a lifetime, batteries are higher priced and more for ‘first movers’.

What are the most common types of solar batteries used in Perth?

Lithium ion and lead acid are the most common types of solar batteries. Lead acid is the oldest and cheapest. However, they have a short shelf life and need regular maintenance. Lithium ion is very popular right now. They have a high energy battery density and require little to no maintenance. Tesla and LG make two popular lithium batteries for solar panels.


Are solar batteries mandatory?

No, you do not have to get solar batteries for your solar panels. It is often recommended, but there are certain instances where you may not have a need for them. For instance, if you are using a grid system then the grid itself acts as a storage reservoir for the energy, which can be drawn upon as needed. But this comes from a common source – you are only not relying on your own pure energy.


What are the benefits of Solar Battery Storage for your home?

  1. Greater Energy Security
  2. Reduce Your Home’s Carbon Footprint
  3. No Noise Pollution
  4. Reduced Electric Bills

How much does a solar battery cost?

The cost is dependent on many factors. You need to use a CEC professional to install the battery, and usually the cost of installing the battery, inverter, and panel come together. It also depends on the battery power (3kwh, 8kwh, 13 kwh, etc). For a 3kwh, you might pay around $3,500 for the battery and $5,500 for the install of battery and inverter. These are general averages -you will pay more or less depending on your preferences and the quality of your installer.

To get the best prices on solar batteries in Perth, it’s best to work with a CEC accredited installer.


What are the different types of solar batteries in Perth?

There are 4 major kinds of solar batteries. They are lead acid, lithium iron, nickel cadmium, and flow. Each has distinct advantages and disadvantages. For instance, nickel cadmium is durable and can operate at extreme temperatures. They are also maintenance free. However, cadmium is extremely toxic and banned in some countries. Flow batteries last for 30 years and are low maintenance, but happen to be quite expensive.


How long does it take to install solar batteries?

It takes an average of 3 to 4 weeks once an agreement has been signed. Two weeks from these is incorporated for supply authority approval and processing. Installation takes 1 to 2 days per 3-6kW capacity.

DC or AC Batteries?

Well for starters, there’s no such thing as an AC battery. If you work out how to store AC power, please give us a call before you tell anybody else. But the term is widely used and perfectly acceptable and our prediction is that ‘AC batteries’ are probably the way of the future.

You can put your batteries on the DC side of the inverter between the panels and the inverter, or on the AC side of the Inverter and your electrical loads. The batteries that go on the AC side like the superb Enphase system are in fact DC batteries with a small inverter in each one. Or you can cut out the extra conversions and just go DC like GCL and LG have done. The problem with the DC batteries is that you have to coordinate with the inverter manufacturers to get everything managed properly. Tesla tried this and came to a cropper recently, dropping their DC batteries before they were even released. Having said that, no such problem from GCL in coordination with Goodwe. Fronius makes batteries and inverters but seems to be going for the billionaire market..

Hybrid Inverters

Please do not believe the hype and buy one of these until you are ready to put your batteries in. Most new battery systems including Tesla will come with a built in inverter for handling the battery management and it will be far superior to buying something now.

What is a solar battery?

A solar battery stores the excess energy generated from your solar panel. They are invariably good investments as they can ensure maximum usage of your energy. It also means you will have energy at times when there is no sunshine.

How much is a solar lithium battery?

Solar lithium batteries are rechargeable batteries that can be attached solar to panels to store excess solar energy. The average cost is around $9,000, but the cost can reach up to $30,000 depending on the brand.

How many solar batteries are needed to power a house?

You should assess how much power you need, how big your solar system is, and when you use most of your energy before determining the number of batteries you need to power your home. Here are the things you need to consider before purchasing solar batteries.

#1. System size. The size of your battery is influenced by the size of your current solar system. You do not have to buy a large battery to carry a small amount of power. However, you need to purchase a modular battery if you plan to expand your small system in the future.

#2. Power versus capacity. The power of a battery is the rate at which the batter can provide electricity at one time (measured in kW), while the capacity of a battery is the amount the battery can hold (measured in kWh).

You have to determine how you use your power when planning to buy the number of solar batteries you need. A battery with a high-power rating is what you need if your household needs a lot of power.

You need more than one battery if you use a low-capacity high powered battery. This could run your entire home but only for a short time. On the other hand, you need a high-capacity low-powered battery if you have fewer people using energy as this can run for a long time.

#3. Usage Timings. The number of batteries you need is influenced by the time of day that you use your power. You need a larger battery if you use most of it in the evening. However, a lower capacity battery is suitable if you use energy evenly between day and night as your solar panel system provides you with power in the day and charges it simultaneously.

How long do solar batteries last?

The service life of home solar batteries is from 5 to 15 years. You need a replacement in the future to align with the 20- to 30-year lifespan of your solar power system.

Different factors affect the lifespan of a solar battery. These are the following:

#1. Battery composition. Lead-acid batteries can only last for three to five years, while lithium-ion batteries can degrade slowly and have a longer lifespan.

#2. Round-trip efficiency. Energy is not all consumed when a battery releases it. This term is round-trip efficiency, which measures the amount of energy a battery can convert into usable power. There are fewer charge cycles and less waste for batteries with a higher round-trip efficiency, which means that it has a longer lifespan and degrades slowly.

#3. Depth of discharge. Solar batteries have their own depth of discharge, which is the percentage of the battery’s total capacity that can be discharged without the risk of long-term damage during each charge cycle. The depth of discharge of lead-acid batteries is between 50% to 80%. On the other hand, the depth of discharge of lithium-ion batteries can reach 90%.

#4. Routine maintenance. It takes effort to maximize the service life of your battery. A regular maintenance every few months is required for flooded lead-acid batteries to ensure that they work correctly. This involves monitoring water levels and keeping terminals clean. On the other hand, lithium-ion and sealed lead-acid batteries need no maintenance.

How can I make my solar battery last longer?

#1. Reduce the number of batteries. You should use 16 batteries or less in the bank. If you install more batteries, this means more connection and higher resistance, which will result in uneven charging.

#2. Rotate your batteries. Periodically rotate batteries within the bank to ensure that all batteries have a good charge.

#3. Use large battery interconnect cables. Doing this reduces resistance and avoids uneven charging. Use a 2/0 size cable for 48V systems and 4/0 for 12V and 24V systems.

#4. Charge batteries. Uncharged batteries for an extended period can cause damage to them.

#5. Use only distilled water. Do not use battery additives or electrolytes to your battery.

#6. Permit gassing or boiling. Batteries should be gassed daily. The gassing of batteries results in hydrogen and water. Thus, your battery bank must have appropriate ventilation to avoid the buildup of hydrogen. Batteries begin gassing at 14.1Vdc(12V nominal system), 28.2 Vdc (24V), or 56.4 Vdc(48V).

How do I know if my solar battery is bad?

Different signs show when a solar battery has gone bad. These include discolouration, excessive leaking, crack or rupture of the case, bulge or bump in the case, and a broken terminal. It is dangerous to have broken or loose terminals as these can cause a short circuit.

What is a hybrid system?

This is where you use both a battery and a grid. This is useful in locations where the grid is unreliable and there are lots of natural disasters. Ideally, the more energy you generate from the sun and use, the better. At the same time, you need energy, especially in the morning and evening when people are getting up or coming from work. There needs to be a mix between convenience and renewability.

What are the different types of solar batteries in Perth?

There are 4 major kinds of solar batteries. They are lead acid, lithium iron, nickel cadmium, and flow. Each has distinct advantages and disadvantages. For instance, nickel cadmium is durable and can operate at extreme temperatures. They are also maintenance free. However, cadmium is extremely toxic and banned in some countries.
