Product description
Product description
The SigenStor EC TP series includes three-phase hybrid inverters with asymmetric output, ranging from 5 to 30 kW. These devices are designed for larger residential and smaller commercial solar systems where managing varying loads per phase and flexible energy management are key considerations.
The inverters serve as the central control units for the Sigenergy SigenStor modular energy storage system, where the inverter, battery, and energy management operate as a tightly integrated system. This enables real-time coordination of generation, consumption, and storage.
The integrated energy management system supports asymmetric three-phase power output, meaning the inverter can provide different power levels per phase. This is particularly advantageous in buildings where consumers are not evenly distributed across the three phases, for example, with larger single-phase loads or mixed residential-commercial consumption profiles.
The TP series features a high DC input voltage range and multiple MPPT inputs, allowing the connection of larger, segmented, or differently oriented solar panel arrays. The inverters work with SigenStor battery modules, and storage capacity can be expanded per module, making the system easily scalable in the future.
In the event of a power outage, the three-phase EC TP inverters also operate in island mode with rapid switching. The system can briefly handle loads exceeding its nominal power, which is important for consumers with high starting currents, such as machinery or business equipment.

How do I choose the right inverter?
How do I choose the right inverter?
When selecting an inverter, the most important aspects are the system size, type, and future expandability.
First, the inverter must be matched to the power and voltage range of the solar panels, and it must also be considered whether the system will be connected to a single-phase or three-phase grid. It is also worth thinking ahead about whether you want to add a battery later, as this requires a suitable (hybrid) inverter.
For three-phase systems, a significant difference exists between symmetric and asymmetric operation. A symmetric inverter distributes power evenly among the phases, while an asymmetric inverter can regulate it differently per phase, according to actual consumption.
The latter solution is more efficient in most households, as it better adapts to daily consumption patterns and can reduce the amount of energy drawn from the grid.
When is it worth choosing a hybrid inverter?
When is it worth choosing a hybrid inverter?
It is worth choosing a hybrid inverter if you are thinking about developing the system in the long term.
This type is an ideal solution if you want to build a battery energy storage system in the future, or if it is important for you to have power supply even in the event of a power outage (with a backup function).
Although hybrid inverters initially represent a higher investment, they are more flexible and allow for later expansion of the system without the need for a complete inverter replacement.
Therefore, it is especially recommended for those who want to optimize their energy consumption and increase energy independence in the long term.
What happens in a power outage?
What happens in a power outage?
In the event of a power outage, whether there will be electricity depends on the inverter type and the system's design.
Traditional grid-tied (on-grid) inverters automatically shut down in such cases and therefore do not provide power for safety reasons, even if the solar panels are generating.
Hybrid inverters – with an appropriate battery – are capable of off-grid (backup) operation, but this is not always a basic function. For many systems, a separate backup box or EPS (Emergency Power Supply) output/add-on is required for the system to operate during a power outage.
With such a design, the inverter disconnects itself from the grid and continues to supply designated consumers (e.g., lighting, refrigerator, essential devices) with the help of the battery.
Therefore, if continuous power supply is important, it is worth checking during the planning phase whether the given inverter supports the backup function and if an additional unit is needed.
What is the warranty for inverters?
What is the warranty for inverters?
Inverter warranties vary depending on the manufacturer and model.
In most cases, a 5-10 year manufacturer's warranty applies, which can be extended with some manufacturers through registration or a separate extension.
The exact warranty period and conditions are specified for each product, allowing them to be clearly checked before purchase.
If you are unsure about your choice, we can help you find an inverter that provides a reliable long-term solution.
What happens if the inverter fails?
What happens if the inverter fails?
If the inverter malfunctions, the first step is to accurately identify the fault.
In many cases, the problem does not originate from the inverter itself, but can be attributed to a configuration, communication, or system connection error, so it is worth checking this first.
If it is a genuine device fault, repair or replacement will be carried out with the involvement of the manufacturer or an official service partner, either within or outside the warranty period.
If necessary, we can assist with fault investigation and initiating warranty claims to ensure a quick and smooth process.
