The Easun Power Hybrid Solar Inverter series are hybrid inverters, combining grid connection, backup power, and battery storage functionality into a single unit. This translates to flexible operational scenarios - ranging from maximizing self-consumption, through providing home or business power during grid outages, up to installations prioritizing energy independence and seamless source switching.

Depending on the model variant, the series offers 1 or 2 MPPT inputs, facilitating yield optimization even under partial shading and enabling PV string connections in various roof orientations without the losses typical of single-axis tracking systems. The high European efficiency translates to genuinely better energy production under variable weather conditions, typical in Poland.

A significant advantage is the monitoring capability - via Wi-Fi and the SmartESS app, and in many configurations also through wired communication (e.g., RS485) and integration with BMS for lithium batteries via RS485/CAN bus. Required protective functions and compliance depend on the model, while the manufacturer's warranty may vary based on the sales channel.

Pros and cons

5 positive · 4 caution
What owners get
Hybrid all-in-one function

The series combines a grid-tie inverter, battery charger, and UPS in a single device, eliminating the need to purchase separate components. It allows for seamless switching between the grid, energy storage, and PV generation - similar to Growatt SPH or Deye SUN-xK-SG04LP solutions, but at a lower price point.

1 or 2 independent MPPT controllers

Higher-end models in the series (e.g., 11 kW 48V) are equipped with 2 independent MPPT tracks, which allows for the connection of PV strings with different orientations or under partial shading without the typical losses associated with a single tracker. A DC voltage of up to 500V provides flexibility in selecting module configurations.

Integration of RS485/CAN BMS

The series enables communication with BMS (Battery Management Systems) for popular lithium-ion batteries (LiFePO4) via RS485 or CAN, allowing for charging management without the limitations typically associated with inverters using only analog protocols. Compatibility includes batteries from brands such as PYLONTECH and DYNESS.

Wide range of power and topologies

The portfolio includes models ranging from approximately 3 kW single-phase to 10 kW three-phase (48 V DC bus), allowing for use in both prosumer and small commercial installations. The available parallel configurations (up to 3 phases) further enhance the scalability of the system.

Low price entry barrier

Models in the 5-6 kW segment are available at a price of approximately $400-$600 (direct-to-consumer), which positions the series clearly below comparable Growatt SPH5000 (~$700-$900) and Deye SUN-5K (~$650-$800) models. This makes it an attractive option for budget-friendly off-grid and hybrid installations.

Trade-offs
Poor after-sales service

Instances of service failing to respond to warranty claims have been documented on Trustpilot and the DIY Solar forums (2024-2025). One user reported a problem from December 2023 to August 2024 without a resolution. This represents a significant risk for installations, where the service's response time is crucial for maintaining functionality.

Manufacturer not on BNEF Tier-1 list

Easun Power is not listed on the Tier-1 Bankable Manufacturers list by Bloomberg NEF. There is evidence that some models in the series are rebranded versions of Voltronic/SRNE platforms, which raises concerns about the actual quality control and long-term technical support provided to competitors such as Growatt (Tier-1 BNEF).

Unstable SmartESS application

Users have reported a loss of communication between the datalogger and the server within just a few weeks of operation (elektroda.pl, 2023-2024). The SmartESS application is described as "complex," and some users are switching to alternative software (Solar-Assistant, Dessmonitor), which involves additional costs (approximately $49 USD per year for Solar-Assistant).

Documented quality control issues

Reports on DIY Solar and Trustpilot forums, among other things, have highlighted issues such as damaged LCD screens in new units, a F09 error (damage to the main board during PV connection), and instances of three defective devices belonging to a single customer. This suggests inconsistent quality control at the production level.

About the Hybrid Solar Inverter series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this model's own.

Does the Easun Power Hybrid Solar Inverter function during a grid outage?
Yes, the Easun Power Hybrid Solar Inverter series features a backup power function. In the event of a power outage, the device automatically switches to battery and solar panel operation. The switching time is so short that sensitive devices (such as routers, computers, and refrigerators) typically do not lose power. This is a key advantage of the hybrid mode compared to standard grid-tie inverters.
What types of lithium batteries are compatible with the Easun Power Hybrid Solar Inverter?
The series supports popular lithium battery brands such as Pylontech, WECO, and Soltaro, through RS485 and CAN communication protocols. This allows the inverter and battery BMS to exchange data in real-time, which improves charging safety and extends the lifespan of the batteries. It is advisable to confirm the compatibility of a specific inverter model with your existing or planned energy storage system before purchasing.
What is the MPPT range for the Easun Power Hybrid Solar Inverter, and what does this mean in practice?
Depending on the variant, the series offers 1 or 2 MPPT tracks. Two independent MPPT systems allow you to connect strings of panels facing in different directions, for example, south and west, without reducing the overall yield. This is particularly useful on pitched roofs or when part of the installation is partially shaded. The model with a single MPPT is suitable for installations with uniform, unshaded panels.
How does the Easun Power Hybrid Solar Inverter's monitoring function through WiFi and the SmartESS app work?
The Easun Power Hybrid Solar Inverter series supports remote monitoring via an integrated or optional WiFi module, as well as the free SmartESS app available for iOS and Android. The app displays current energy production, battery status, load consumption, and historical statistics. It also allows for configuring operational priorities directly from a smartphone. For installers, an RS485 port is also available for integration with building management systems.
What is the warranty for Easun Power Hybrid Solar Inverters?
The standard manufacturer's warranty for Easun Power Hybrid Solar Inverters (series) is 12 months from the date of purchase and covers manufacturing defects and malfunctions that occur during normal operation. The warranty period may vary depending on the sales channel and market, so it is advisable to check the terms offered by a specific distributor before making a purchase, as they may provide extended warranty coverage.
Is the Easun Power Hybrid Solar Inverter suitable for a single-family home in Poland?
Yes, the series is designed for residential use and is suitable for single-family homes. The energy storage system allows for maximizing self-consumption, which is particularly cost-effective given Polish billing rates. The high European efficiency translates to better performance in conditions with variable solar radiation, typical of Poland. However, it is important to ensure that the chosen model meets local technical requirements and has the certifications required by the grid operator.
