The Easun Power POW-HVM-PRO series is a hybrid inverter solution combining grid connectivity with backup functionality and flexible integration with energy storage systems. In practice, this means one inverter serves for self-consumption, supporting critical circuits and enabling system expansion toward greater energy independence. Its key feature is multi-source management-intelligent switching between PV, battery, and grid, including the capability to export excess power to the grid in grid-tie mode. The use of two MPPTs optimizes energy yield from panels with different orientations, shading variations, or mismatched strings, without compromising project design. High European efficiency translates to significantly better performance in typical operating conditions in Poland. Monitoring is convenient via built-in WiFi and a mobile app, while BMS communication (including RS485/CAN) facilitates integration with popular lithium batteries. The series is designed for both homes and small commercial buildings, available in parallel and three-phase configurations, with comprehensive protection features and manufacturer support.

Pros and cons
Two independent MPPT trackers allow you to connect strings with different orientations or inclines without any interference. In Polish conditions (pitched roofs, partial shading), this translates to a significantly higher yield compared to a single MPPT system, without the need for optimizers.
A single power converter handles self-consumption, exporting excess power to the grid, battery charging, and providing backup power for critical circuits. This eliminates the need for a separate grid-tie inverter and a separate UPS, simplifying the design and reducing the overall system cost.
Built-in RS485 and CAN protocols enable integration with popular lithium batteries (Pylontech, WECO, Soltaro) without the need for external converters. The inverter can control charging at the cell level, which extends the lifespan of the energy storage system.
The integrated Wi-Fi module and mobile application (SmartESS) allow for monitoring the installation without the need for additional equipment. The elimination of the need to purchase a separate data logger (which costs around 150-400 zł with competitors) reduces the overall system cost.
The series supports connecting up to 9 units in parallel systems or a three-phase configuration, allowing for power scaling from residential installations to small commercial facilities without the need to replace the inverter - simply adding another module is sufficient.
Easun Power does not appear in the PVBL Top 20 Global Solar Inverter Brands 2025 ranking, unlike Growatt, Deye, and Solis, which dominate the Chinese hybrid inverter segment. The absence of a ranking position indicates a lower level of confidence regarding the continuity of technical support and the availability of spare parts over a longer period.
The POW-HVM-PRO series is based on the same hardware platform as PowMr, Powland, and Anjei products (identical enclosure, firmware, and instructions). This means no unique engineering and makes it difficult to identify the responsible service provider - users on forums (elektroda.pl, diysolarforum.com) report difficulties in obtaining support from a specific brand.
Reports are emerging on the Trustpilot platform and on the DIY Solar Power Forum and elektroda.pl (2024-2025) regarding malfunctioning tracking, a lack of response from the service regarding warranty claims, and defective products from serial batches. For commercial installations, the absence of a guaranteed Service Level Agreement (SLA) can pose a significant operational risk.
