High performance solar batteries

Discover solar batteries from leading manufacturers, with the latest technology and top quality. Store your energy efficiently and use it during the night and on cloudy days.

Solar batteries from top brands

Solar batteries are the perfect match for your plugin solar kit, allowing you to store your solar energy and save it for later use. The solar panels capture sunlight and convert it into direct current (DC) electricity. The solar battery system stores it, before the micro inverter converts it into alternating current (AC) to power your appliances and devices. There are also all-in-one solar battery systems that include battery, controller and micro inverter into one device.

How do solar battery plugin kits work?

Solar batteries for plugin solar kits allow homeowners to generate electricity from sunlight using solar panels and store the surplus energy for later use. The kits are designed for easy self-installation.

Solar panels: The solar panels capture sunlight and convert it into direct current (DC) electricity using photovoltaic cells. This energy is then used to power your home or charge the battery.
Battery storage: Any excess electricity generated by the solar panels that isn’t used immediately is stored in the solar battery. This stored energy can be used during times when the panels aren't generating electricity, like at night or on cloudy days.
A battery management system (BMS) is a vital component in solar batteries, ensuring the safe and efficient operation of the battery pack by monitoring and controlling several key parameters. It tracks the state of charge (SoC) to prevent overcharging or deep discharging, regulates voltage and current to maintain safe levels, and monitors temperature to avoid overheating by adjusting charge rates or activating cooling systems. The BMS also balances the cells to ensure uniform charging and discharging, extending the battery's lifespan, while providing protection against over-voltage, under-voltage, and short circuits. Additionally, it communicates with external controllers like the micro inverter, offering critical metrics such as SoC (battery percentage), SoH (battery health), and SoE (safe operating conditions).
Micro inverter: The electricity produced by the solar panels and stored in the battery is in direct current (DC). The micro inverter converts it into alternating current (AC), which is compatible with your home’s electrical network.

Plugin system: Solar batteries are designed for quick and easy self-installation. The kit can be plugged directly into a standard power socket, eliminating the need for an electrician or professional installer.

Choosing the right solar battery system for your kit

When choosing a solar battery system, you should consider several important aspects:

Innovation

Choose solar batteries that prioritize innovation and cutting-edge technology to effectively meet your home's energy needs. Consider a modular design that allows easy expansion, enabling you to increase your energy storage capacity. Additionally, look for solutions that offer extra components such as an integrated micro inverter and smart controller to ensure a rapid response to energy fluctuations.

Durability

Choose solar batteries fabricated with the highest quality materials to withstand harsh weather conditions and outdoor use, such as exposure to rain, dust, and varying temperatures. There are standards to ensure that products are durable, such as IP65, which guarantees protection against water and dust.

Warranty

A good solar battery system should come with a long warranty to protect your investment. Key aspects to consider include lifespan (the expected operational duration, often measured in years), production warranty (which guarantees that the battery will produce or store a certain percentage of its original capacity over a specific period), and cycles (the number of complete charge and discharge cycles a battery can undergo).

Manufacturer

We work with trusted, professional manufacturers who have a proven track record of delivering high-quality solar batteries. Robinsun selects leading manufacturers that focus on battery production and can guarantee the highest quality products.

Solar batteries – A smart, sustainable, and affordable investment

Whether you’re looking to save money, reduce your environmental impact, solar batteries offer a powerful solution. With advancements in technology and growing affordability, there has never been a better time to make the switch to solar energy. At the heart of this transition is the commitment to a cleaner, more sustainable future. By investing in solar batteries, you not only improve your own energy efficiency but also contribute to the global shift toward renewable energy. If you’re ready to take the next step, contact us to learn more about the options available and get started on your journey toward energy independence today.

Why invest in solar batteries?

The benefits of solar batteries go far beyond saving on your energy bills. Here are some of the most compelling reasons to invest in solar energy:

Cost savings

One of the most attractive features of solar batteries is the potential for long-term savings. While the initial installation cost may seem high, most homeowners experience significant reductions in their energy bills. Robinsun solar batteries are very affordable, providing the best quality available in the market. With two Robinsun solar panels positioned at 20 degrees in Spain facing south, they are estimated to produce 1.951 kWh per year. Your annual savings would be calculated by multiplying by the electricity price (the average price in Spain in 2024 is €0.23), which equals approximately €458. With a smart meter installed in your solar battery system, any surplus energy that you produce doesn’t go to the grid; you can keep it all and use it later, allowing you to save even more each year.

Environmental impact

Solar batteries are a great option for a clean and renewable energy source. By using solar energy, you reduce your reliance on fossil fuels and decrease your carbon footprint. Solar energy produces no greenhouse gas emissions, making it one of the most environmentally friendly energy options available today. We are proud to have achieved a climate impact certification for our plugin solar kits. A plugin solar kit with two solar panels in Spain saves 340 kg of CO2/year, for at least 30 years! They benefit you both in terms of savings on your power bills and in CO2 saved by producing your own solar energy. This certification, granted by certification company Impact Forecast BV, an independent and neutral third-party company, marks a significant milestone in Robinsun's journey toward reducing our customers’ carbon emissions and contributing to a greener future.

Energy independence

Solar batteries allow you to generate your own electricity and store it, reducing your dependence on the grid. This is particularly beneficial during times of energy shortages or rising electricity prices. With solar batteries, you take control over your energy usage and costs.
