Is there a way to limit the output power of an inverter?
Without grid the inverter always tries to deliver the power needed by the loads. There is no way to limit the output power. You have AC Out 2 and (depending on the exact model you have) at last one relay that you can use to switch off loads in case of overload. "I expected that the grid would kick in as soon as I am over the inverter's max load."
What is a control state in an inverter?
Each control state is a combination of the following three fields: AC output power limit – limits the inverter’s output power to a certain percentage of its rated power with the range of 0 to 100 (% of nominal active power). CosPhi – sets the ratio of active to reactive power.
What is a maximum AC current limit on an inverter?
The current limit can be set to any value between 0 and the inverter’s max AC current [A] (the LCD will allow setting to a higher value but the inverter will never exceed its maximum AC current). Wakeup Grad – Wakeup Gradient: enables gradual power production when it begins operation after a fault or an inverter reset.

Do PV inverters oversize?
PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.
What is a power limit in a solar inverter?
The setting is percent-based. It is the desired active power limit divided by the nominal power of the inverter, as shown in the equation below. For example, this means if a user wants the inverter to only generate a maximum of 3.6kVa (for EEG2012, 70% of the kWp of the PV array) and the inverter has a nominal rating of 5kVA.

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

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.
