What is the difference between kWh and kilowatt-hour?
A kilowatt-hour is the unit of energy that measures how much power has been used or stored over a period of time. Unlike kW, which tells you the rate at which energy is being used, kWh tells you the total amount of energy consumed or generated. One kWh is the amount of energy used by a 1 kW device running for one hour.
What is a kilowatt (kW)?
A kilowatt (kW) is a unit of power, measuring the rate of energy consumption or production. It refers to the period during which energy is consumed or generated at a certain moment. Power is the flow of energy over time, and kW is the measure of that flow.
What does kWh stand for in solar?
kWh stands for kilowatt-hour. A kWh is a measure of energy (not power). If your solar panels (for example) continuously output 1 kW of power for a whole 60 minutes, you will have produced 1 kWh of energy. The amount of electricity you use (or generate) is defined in kWhs. e.g. “My solar system produced 4 kWh of electricity today!”
What is a 10 kWh battery?
In energy storage systems, such as in home batteries or solar energy systems, kWh refers to the total capacity of the storage unit. A 10 kWh battery might store enough energy to run your home for several hours, depending on just how much it is used.
How do you calculate kWh?
kWh is calculated by multiplying the power usage (in kilowatts) by the time the device is used (in hours). The formula is: Energy (kWh) = Power (kW) × Time (hours) For instance, if an electric vehicle charger consumes 7 kW of power and is used for 2 hours, the amount of energy consumed would be: 7 kW × 2 hours = 14 kWh
What are energy storage units & measurements?
As the energy storage industry rapidly evolves, understanding the units and measurements used to describe storage capacity and output is crucial. Energy storage technologies play a pivotal role in balancing energy supply and demand, and various units are used to quantify their capabilities.

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.
500kW Battery Energy Storage System
MEGATRON 300 & 500kW Battery Energy Storage Systems are AC Coupled BESS systems offered in both the 10 and 20′ containers. Designed with either on-grid (grid following) or hybrid (grid forming) PCS units, each BESS unit is capable of AC coupling to new or existing PV systems making them an ideal solution for commercial/industrial customers.
