The most common questions about solar batteries – Part 2


When it comes to solar batteries, there are so many things you need to consider. From size and capacity to functionality and lifespan, knowing your solar battery will take you one step closer to reaching a great energy efficiency, whether it’s for residential or commercial use. Read more about solar batteries in this week’s blog post.

The great progress in battery technology for the past decade has led to an increased interest in battery storage within renewable energy projects. And, as costs continue to decrease, we expect to see solar solutions being implemented more often, enabling the transition from traditional to green technology. So, to go or not to go off-grid?

If you haven’t found an answer to your question in our last blog’s FAQs yet, then you may want to keep reading.

Are you looking for strong and affordable solar batteries?Ask our solar experts at Black Frog and find out which one is more suitable for your application.

1. What are the legal requirements when installing a solar battery?

First of all, the cabinet where the solar battery is stored should be built to comply with the standards and building codes (i.e. fire and building regulations) applicable in each region of Australia. Your solar energy expert should be aware of these requirements.

2. Do solar batteries work in case of a blackout?

blackoutThe answer is: it depends on the battery type. Some will work during a blackout, and some may operate following a brief power outage. If you want a permanent supply of electricity, make sure you choose an uninterruptible power supply (UPS) solar battery.

If the solar battery is charged during a blackout, it may be able to supply power to your building. However, you might not be able to run as many appliances as normal. Alternatively, your installer may need to wire specific appliances so you can use them in a blackout. We recommend you to discuss your needs with your solar expert before making any buying decision.

3. Are solar batteries noisy?

In general, batteries themselves should be quiet; but the system attached to them, such as the inverter, can make some noise. What you may hear are actually the cooling fans and the circuits releasing an electronic ‘buzz’. However, the sound is relatively similar to a regular solar inverter.

4. What is the lifespan of a solar battery?

The average lifespan of a solar battery storage system is around 5 to 7.5 years for lead-acid and 11-15 years for lithium-ion batteries. However, all batteries are vulnerable if they are over-discharged or exposed to extreme weather.

Sometimes, retailers offer a warranty as an ‘energy throughput’ figure, which means that batteries will store and deliver a given amount of energy, no matter how quickly that limit is reached. For instance, energy throughput for lithium-ion batteries ranges from 4000 to 6000 cycles (charges/ discharges of the battery) at 80 per cent discharge rate.

5. Will solar batteries affect the performance of the other appliances?

Once your solar battery is installed, all the electrical appliances will continue to operate as normal. If you are looking to go completely off the grid, though, you will need to consider how much power your building appliances use – whether it’s for residential or commercial use – and choose a system to meet your specific needs and requirement.

In conclusion, installing a solar battery storage system can make your life more convenient all year round without worrying about the weather. As it becomes more common in both public and private environments, it is important to choose the most cost-effective product.
