What battery do I need for a 5kw Solar System?
A 5kW solar system may require a lithium-ion battery with a capacity of around 10-15 kWh, depending on your daily energy consumption patterns. Lead-acid batteries are a more traditional choice and have been used in energy storage for many years.
What battery capacity is needed for a 5 kW solar system?
If your home has a 5 kWp solar system, you’ll want a battery capacity of between 9.5–10 kW. This capacity will allow the solar system to efficiently charge it.
What battery size should a 5kW system have?
In a 5kW system, the battery size should accommodate your energy use patterns and preferences. For example, if you plan to use 15 kWh daily, a battery with a capacity of at least 15 kWh ensures you have enough stored energy. Choosing the right battery type and capacity reduces reliance on the grid and enhances your overall sustainability.
What size solar battery do I need for a 3KW system?
For a 3 kW solar PV system with 5-10 kWh daily energy consumption, you can use a 4 kWh battery to maximise returns or a 22 kWh battery to maximise energy independence (and yield about three days of energy autonomy). For 11-15 kWh daily energy consumption, use a 4 kWh battery.
How much battery do I need for a solar PV system?
For a 10 kW solar PV system with 5-10 kWh daily energy consumption, you need a 4 kWh battery to maximise returns or a 35 kWh battery to maximise energy independence. For 11-15 kWh daily energy consumption, you need an 8 kWh battery to maximise returns or a 65 kWh battery to maximise energy independence.

Featured Solar Products
High - Efficiency Photovoltaic Panels
Our photovoltaic panels are at the forefront of solar technology. With advanced cell designs and high - quality materials, they offer exceptional energy conversion rates, allowing you to maximize your solar energy harvest. Whether installed on a residential rooftop or a large - scale solar farm, these panels are built to last, withstanding harsh weather conditions and providing reliable performance for decades.
Advanced Monocrystalline Solar Panels
These advanced monocrystalline solar panels are crafted from single-crystal silicon, which endows them with outstanding electrical properties. They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
