Solar Battery Guide

As mentioned in the video, solar batteries really are the HOT topic in the marketplace at the moment, everyone wants one!

The problem is there is also a lot of confusion, it’s actually quite scary how so many companies are selling them, and many can not fully explain how they operate. Some of the quotations we have seen over the past few years have been horrific, like selling a hybrid inverter with an AC-coupled battery, with the AC-coupled battery already having a built-in inverter.

There are lots of manufacturers of batteries in the marketplace, all trying to compete for your business, slowly they’re becoming more competitive in price, and as demands grow, economies of scale mean the price should reduce a little further too.

However, if you don’t want to wait any further, there are TWO ways to connect batteries to your solar PV system, either an AC or DC coupled solution. please click on the relevant image below to be taken to a more in-depth page about that option, and the manufacturers we trust within the industry to provide the solution to meet your needs. (AC = if you already have a solar system installed / DC = if you are going to buy a new solar system and want a battery installed from the start)

Let’s go a little deeper…

Solar batteries can be an essential component of any solar energy system, as they allow you to store the energy generated by your solar panels during the day so you can use them at night, during periods of low sunlight, or during a blackout from the grid.

Additionally, solar batteries enhance the overall efficiency and sustainability of your solar power setup. By storing excess energy, these batteries reduce reliance on the grid, leading to significant savings on electricity bills.

Moreover, they play a crucial role in promoting renewable energy usage, as they ensure a consistent power supply even in areas with variable sunlight conditions.

Types of Solar Batteries

There are several different types of solar batteries available on the market today, each with its own unique benefits and advantages. Let’s take a look at some of the most popular solar batteries available, and why they might be good for your home or business.

1. Lead-Acid Batteries

Have been in use for many decades, relatively inexpensive, and easy to maintain. However, they are heavy, bulky and have a limited lifespan compared to other types of batteries.

2. Lithium-Ion Batteries

Rapidly becoming the most popular type of solar battery, lightweight, compact and has a longer life span. They are more expensive than lead-acid but their benefits far outweigh the cost. They are more efficient, have a higher energy density, and can charge and discharge at a much faster rate.

3. Flow Batteries

Slowly gaining popularity in the renewable energy sector. They use a liquid electrolyte that flows through the battery to provide power. They are highly scalable, extremely durable and have a long life span.

4. Saltwater Batteries

This relatively new type of solar battery uses a saline solution instead of traditional chemicals to store energy. They are non-toxic, non-flammable, good life span, and are more affordable than lithium-ion, making them an attractive option for those on a tight budget.

Choosing the right solar battery for your home or business depends on several factors, including your energy storage needs, budget, and overall energy usage.

Working with a renewable energy expert can help you determine which type of solar battery is right for you and your specific needs. Take the short quiz and we’ll put you in touch with 1, 2 or 3 endorsed energy experts in your local area and see what the benefits of a Battery Energy Storage Solution (BESS) are for yourself.

AC vs DC Coupled Battery

However, if you have a HYBRID inverter, then you can connect a DC-coupled battery, which is charged directly from your renewable energy source, be it solar panels or wind turbines. During a power outage, the battery can provide power to your DC loads.
