The Easun Power IGrid SV II series are hybrid on-grid/off-grid inverters, combining auto-consumption with the possibility of island operation as backup power. In practice, this means flexible mode switching - the installation can normally work with the grid, but can also supply selected circuits from PV and battery, or even operate without batteries when conditions permit. The built-in MPPT ensures stable power tracking, facilitating energy gain under variable weather conditions and typical installation constraints. If the installation has different rooftop sections or periodic shading, the number of MPPT channels is meaningful - it allows independently optimizing the operation of module strings.
High European efficiency translates to more energy delivered to consumers annually, as it considers typical, variable loads. Monitoring and configuration functions are provided for operational supervision, and service interfaces such as USB support communication. The series is mainly targeted at residential and small commercial installations, where safety, ease of operation, and the possibility of expansion are important.

Pros and cons
The inverter can handle both grid and island operation - in the event of a grid failure, it automatically switches to PV and battery power, eliminating the need to purchase a separate UPS for specific circuits. This solution is less common in the segment of budget-friendly grid-tie inverters of this class.
A power factor close to 1.0 (PF=0.99 according to the ENF datasheet) minimizes reactive losses and meets the requirements of network operators for prosumers, thereby reducing the risk of being charged for reactive power.
The MPP 120-430 V (max. DC 450 V) range allows for flexible selection of the number of modules in a string without exceeding the tracking window, which is important for typical residential installations using 380-420 Wp modules.
With dimensions of 468×295×120 mm and a weight of 13 kg, it is feasible for a single person to assemble it without specialized equipment - offering an advantage over heavier hybrid units like the Sofar HYD (around 18-22 kg) in a similar power range.
The manufacturer has officially ceased production of the IGrid SV II line. This means that spare parts will be limited, there will be no firmware updates, and there is a risk of lacking technical support after the warranty period expires.
The datasheet indicates a 1-year manufacturer's warranty - significantly below the market standard (Solis, Growatt, and GoodWe offer 5-10 years). Independent reviews on Trustpilot (2025-2026) document instances of Easun Power neglecting service requests during the warranty period.
A single MPPT tracker eliminates the need for independent optimization of strings on different roof areas or with different orientations. Competitive hybrid inverters in this class (e.g., GoodWe ET, Growatt SPH) offer 2 MPPT in a similar power range, providing higher yields even with partial shading.
The maximum efficiency of 95% (as stated in the ENF datasheet) is significantly lower than the modern hybrid inverters of this class: Solis S6 achieves 97.7%, GoodWe ET achieves 97.6%, and Growatt SPH achieves 97.5%. The difference of 2-3 percentage points over a year translates into a real reduction in energy yield.
Interfaces limited to RS-232 and USB prevent remote monitoring without an additional communication module. Modern inverters of this class (Sofar, Solis, Deye) offer WiFi or LAN as standard, without extra costs.
