The Easun Power Hybrid Inverter/Charger series comprises all-in-one hybrid inverters integrating a sinusoidal inverter, an MPPT charge regulator, and a battery charger into a single unit. This design simplifies wiring and reduces installation setup time. This solution is particularly suitable where reliable emergency power supply (UPS mode) and seamless switching between PV, grid, and battery power are essential. Depending on the variant, the series features either one or multiple MPPT channels, aiding energy harvest under partial shading and when panels operate in different orientations (e.g., east-west). High European efficiency translates to fewer losses in real-world conditions, delivering more energy to consumers annually. Users have access to a local display, communication interfaces (e.g., RS485, and CAN/USB in selected models), and monitoring via WiFi and the SmartESS app. The inverters are compatible with popular 48V energy storage systems, including LiFePO4, and offer features supporting their operation. Selected models feature certification CE (IEC 62109-1/2) and market/seller-dependent warranty. Ideal for homes, farms, and small commercial facilities aiming to increase self-consumption and grid resilience during outages.

Pros and cons
Integrating a sinusoidal inverter, an MPPT (Maximum Power Point Tracking) controller (with charging current ranging from 120-150 A depending on the model), and a battery charger into a single enclosure reduces assembly time and minimizes the number of cable connections compared to a configuration using separate components.
Models 11-12 kW are equipped with two independent MPPT (Maximum Power Point Tracking) strings (totaling up to 150 A), which improves performance under various orientations of the panels (e.g., east-west) or with partial shading compared to models with a single MPPT string in the same price range.
The series includes models ranging from approximately 3.2 kW to 12 kW; selected units support parallel operation and a 3-phase configuration, enabling gradual expansion of the installation without replacing the inverter.
The inverters support RS485 communication with 48 V/51.2 V LiFePO4 batteries (including the Easun PowerWall 200 Ah system), as well as classic technologies (AGM, Gel), which simplifies integration with popular energy storage systems in the EU market without the need for additional protocol converters.
The CE certification, compliant with IEC 62109-1/2, meets the safety requirements of the European market and is a necessary condition for legal sale and connection to the grid within the EU.
Users on the DIY Solar Power Forum (in the 2024 thread) report frequent offline status of the device despite an active internet connection, a 6-minute data refresh delay, and significant discrepancies in reported production (reported cases: 160 kWh in the app versus actually 4-5 kWh displayed on the inverter screen). Some installers are switching to external monitoring solutions (e.g., Solar Assistant) as a workaround.
Reports from online forums indicate a lack of security in the Wi-Fi layer of certain models; the manufacturer refuses to provide the communication protocol, which makes local monitoring difficult and raises legitimate concerns about the cybersecurity of devices connected to the power grid.
The standard warranty is 3 years, while comparable manufacturers in the higher segment offer: Growatt - 5 years, Deye - 5-10 years, SMA/Fronius - up to 10 years with the option to extend. A shorter warranty period increases the risk of service costs over the typical 20-year lifespan of an installation.
Easun is classified by independent industry rankings as a budget-oriented brand (below Deye, Growatt, and Goodwe), with a smaller network of authorized distributors and service centers in Poland and the EU. Its peak efficiency, which is around 93-96% (depending on the model), remains below the 98.4-98.6% offered by Growatt and Deye in comparable power classes.
