For a long time, residential, commercial and industrial properties have depended on electricity from fossil fuels. With the cost of extraction and production going up and concerns about climate change, there’s a revolution in renewable energy. Governments and private companies have invested heavily in renewables as a way of reducing reliance on fossil fuels and shifting to renewables such as wind, solar, geothermal.

One of the biggest trends in the renewable energy industry is the development of high capacity Energy Storage Systems (ESSs). The greatest challenge in adoption of renewables has always been intermittency, and this is where ESS technology has come in to help.

Energy storage solutions are the future of renewables as they give energy security to people using renewable sources of energy such as solar. If you have a solar energy system in your home, you can now store energy and use it whenever your PV arrays can’t deliver optimal output.

This post explores energy storage systems in more detail and looks at the installation process.

Importance of an Energy Storage System

With adequate storage, energy producers including homes and commercial; facilities can now store excess electricity for later use. Solar energy batteries are the best example of energy storage systems on the market.

The revolution in energy storage has also been fueled by developments in the automotive industry where electric cars rely on high-capacity batteries for enhanced functionality. For property owners, electrical energy storage systems (EESS) help store power generated from renewable resources for use when power goes off or during peak electrical demand periods. 

With an energy storage system for your solar system, for instance, you don’t have to worry about national grid outages. The storage system allows you to use clean energy throughout the year.

You get more value from your renewable energy installation. You save on costs of electricity as solar energy is cheaper. While most solar PV systems take years to pay off, you can shorten the pay-off period with the best storage system.

Energy storage systems are hailed as the future of renewables because they allow property owners to go off-grid. By cutting dependence on fossil fuel-powered electricity, energy storage contributes hugely to efforts to curb climate change.

If more consumers switch to solar and leverage the best storage systems, the impact on the environment would be significant. There would be a reduction in emissions which would reverse the devastation caused by global warming.

Types of Energy Storage Solutions

When choosing an energy storage system for your home, you have multiple options on the market. The best example is the use of solar energy batteries. You can choose between:

  • AC storage system: AC coupled storage systems have an inverter. When your photovoltaic system produces direct current (DC), the inverter turns this direct current into alternating current for lighting and appliances. The built-in inverter turns the AC voltage back into DC voltage for storage. The double conversion causes loss of energy than with a DC coupled system.
  • DC storage system: The system is installed before the inverter and energy is stored as direct current. Conversion only happens when the current leaves the energy storage and this reduces losses.
  • PV battery storage: On the market are different solar energy batteries such as lead-gel, lead-acid and lithium-ion batteries. Lead-acid batteries have been around for a long time but they require more maintenance. Lithium-ion solar storage batteries are more advanced and require minimal maintenance. Li-Ion batteries also last longer (15 to 20 years), have a higher cycle stability and boast a discharge depth (DoD) of 100%.

When choosing the best energy storage system for your home, you need to partner with a certified solar installer. Calculate the capacity of your renewable power system against your annual power consumption.

This helps to get the right power rating for your solar energy batteries or other storage system. You should also consider the reliability of the storage system manufacturer and efficiency rate of the battery you install. Go for a low maintenance battery with a longer life span and look for a warranty from both the manufacturer and the solar contractor.

Installing Your Energy Storage System

Every energy storage system differs in design and functionality. You shouldn’t think of a DIY energy storage installation because of the safety risks involved. An experienced solar installer has the prerequisite tools and expertise to get the job done safely and within the required time.

The solar professional also helps design the solar PV system or redesign it in the case of a battery upgrade. Some considerations when you install your energy storage system include:

  1. Finding a certified solar installer for an effective installation
  2. Evaluate the right storage system for your home
  3. Design and plan the electrical energy storage system (ESS) installation
  4. Procure the hardware required including inverters, wiring, cables, interface, solar regulators, solar panels, energy meter accessories including an energy meter and sensors, and Wi-Fi module for smart solar systems,  
  5. Set up parallel and/or 3 phase inverter/chargers if your ESS unit has multiple inverter/chargers
  6. Configure the inverter/chargers and consider crucial settings such as the battery monitor settings, charger settings, ac input limit settings and grid settings
  7. Commissioning of the system

Harnessing the Full Benefits of Renewables  

If you plan to install a renewable power system at your home or commercial facility, one of the top considerations should be the storage.  With the best energy storage system, you maximize the benefits of solar, wind or any other renewable you want to install.

While a good ESS might look like an additional cost, this unit can help your clean energy project pay off faster. The storage system gets you off the grid fully and you always have backup power even when there’s isn’t enough output from the wind turbines or solar PV arrays. It’s a smart way to reduce carbon footprint in your home or business and leverage clean energy credits and invectives.

Ready to get the most out of your clean energy system? Invest in the best energy system storage today. The high cost of the unit eventually pays off and makes it possible for you to enjoy the whole range of benefits of renewables.
