How do I choose the right inverter size?
To choose the right inverter size, consider the difference between surge power and continuous power. Surge power is the peak power needed to start a device, while continuous power is the amount required to keep it running. These factors play a significant role in determining the right inverter size for your setup.
How do you calculate wattage for an inverter?
To accurately determine the total wattage needed for an inverter setup, add up the running watts of all devices you plan to power. It’s important to calculate both the running watts and the surge watts for appliances with electric motors.
What is the capacity of an inverter battery?
The capacity of an inverter battery, measured in ampere-hours (Ah), determines how much power it can store and supply over time. A higher Ah rating means the battery can provide backup power for a longer duration before requiring a recharge. The basic formula for calculating battery capacity is:
What should you calculate first when sizing an inverter?
Always compute the total wattage needed for all appliances to be powered to ensure peak performance when sizing an inverter. This guarantees that the inverter can adequately supply power to all devices without overloading.
Why should I increase my DC inverter capacity?
To accommodate growing demands and guarantee flexibility for future expansions in power needs, upgrading inverter capacity is essential. Anticipating the need for additional power due to new appliances or increased energy consumption is vital when determining the right size inverter for your DC system.
How does an inverter charge a battery?
The inverter system also has some charging system that charges the battery during utility power. During utility power, the battery of the inverter is charged and at the same time power is supplied to the loads in the house. When utility power fails, the battery system begins to supply power via the inverter to the loads in the home as shown below:

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.
