Importantly, the device can operate without an attached energy storage system, which lowers the initial investment and allows for phased expansion of the installation. - **MPPT (Maximum Power Point Tracking) 120 A, with a voltage range of 120-450 V DC** - The declared ability to track the maximum power point is 99.9% at an input current of up to 120 A and a DC PV voltage of 120-450 V. The wide voltage range (starting from 120 V DC) means that the tracker operates even in low-string configurations or under limited morning and evening sunlight. - **Scalable to 9 units in parallel** - The integrated parallel connection allows for connection of up to 9 inverters (totaling approximately 50 kW), with the option for three-phase operation. In the budget-friendly hybrid segment, most competitors (e.g., Growatt SPF 5000ES) require additional modules or limit parallel operation to 3-6 units. - **Native BMS + WiFi communication** - The RS485 port with the SRNE protocol enables communication with popular LiFePO4 batteries (e.g., JK BMS after proper configuration). The built-in Wi-Fi and dedicated mobile app eliminate the need to purchase external data loggers - this is the standard in this price range. - **Attractive price-to-function ratio** - Within the 5-6 kW hybrid inverter segment with Wi-Fi, BMS (Battery Management System), and parallel functionality, IGRID-VX-IV series models are available at prices significantly lower than comparable models from Deye (SUN-6K-SG03LP1-EU) or Growatt SPH 6000TL3 BH-UP, while offering similar features. This makes them an attractive option for prosumer installations with limited budgets. ### Cons - **Documented power fluctuation exceeding 3.8 kW** - Users on the DIY Solar Power Forum (in a thread from 2024/2025) have confirmed a recurring issue: when the PV power exceeds approximately 3.8 kW in export mode, the inverter periodically resets the output power to 0, after which it returns to its nominal value - this cycle repeats every few seconds. This problem does not occur during battery charging, which suggests a fault in the grid-feed section of the inverter, rather than in the DC section. - **BMS SRNE Protocol - Not Voltronic** - The VX-IV series uses the SRNE communication protocol (not Voltronic, as in the older SV-IV), which causes communication error #58 with BMS configured for the Voltronic protocol. Users report incompatibility, particularly with the IBattery-EA module, which does not establish a session with the inverter without protocol switching. - **One MPPT tracker** - A single MPPT (Maximum Power Point Tracking) controller limits the efficiency of installations with a pitched or partially shaded roof. Competitive models in a similar price range (e.g., Deye SUN-6K-SG03LP1-EU) offer 2 independent trackers, which, in complex panel configurations, can translate into a significantly higher annual energy yield. - **Tier-1 supplier - service risk** - Easun Power does not appear in the tier-1 rankings of BNEF or Clean Energy Reviews (2025). In comparison to Growatt and Deye, the network of authorized service centers in Poland and Europe is limited, which, in the event of failures outside of the warranty period, extends repair times and makes it more difficult to obtain original spare parts. ## About this series The **Easun Power IGRID-VX-IV** series are hybrid **on-grid and off-grid inverters**, combining self-consumption with the ability to feed excess back to the grid and operation during power outages. They prove effective in residential and small commercial installations where flexible energy management matters as much as traditional grid-tie. The applied **MPPT** helps maintain stable string performance in varying sunlight conditions. For more demanding rooftops, it's worth noting that a single tracker often suits simpler layouts-installations with different roof orientations or frequent shading benefit more from additional MPPT, offering greater design flexibility. This series stands out with the option to operate **with or without an energy storage system**, along with a BMS communication port, facilitating integration with popular lithium batteries. It features built-in **WiFi**, a monitoring app, and standard service interfaces. For investors, declared certifications (e.g., CE) and the manufacturer's warranty are also crucial. ## Questions ### Can the Easun Power IGRID-VX-IV inverter operate without batteries? Yes, the IGRID-VX-IV series supports operation both with and without a battery. In battery-less mode, the device functions as a standard on-grid inverter, selling or consuming energy from the grid. Adding a battery enables full hybrid functionality: self-consumption, buffering of excess energy, and backup power during grid outages. ### What types of lithium batteries are compatible with the Easun Power IGRID-VX-IV? The inverter supports lead-acid (gel, AGM, flooded) and lithium LFP and NMC batteries through communication with the BMS via RS485. Integration with popular BMS systems, such as Pylontech, JK BMS, Jikong, and Daly, has been confirmed. Important: The VX IV uses the SRNE protocol, which differs from the Voltronic protocol used in the SV IV series. Therefore, it is advisable to check compatibility with a specific battery model before purchasing. ### Can the IGRID-VX-IV be connected in parallel to increase the system's power output? Yes, the IGRID-VX-IV series includes an integrated parallel processing board and supports a total power of up to 30 kW. It can be configured for single-phase or three-phase operation. This allows several 5.6 kW units to be combined into a larger installation without the need to purchase additional control equipment. ### What is the warranty on the Easun Power IGRID-VX-IV inverter? The manufacturer offers a 3-year warranty. The device has CE, RoHS, and SAA certifications, which confirm compliance with European and Australian safety standards. However, it is advisable to verify the warranty terms with the distributor before purchasing, as some importers offer additional local service support. ### Does the IGRID-VX-IV have built-in Wi-Fi, and what does the installation monitoring system look like? Yes, the IGRID-VX-IV series includes a built-in Wi-Fi module, so you don't need to purchase a separate dongle. Monitoring is performed through the manufacturer's dedicated mobile application, which displays current production, battery status, and energy import/export. Standard RS485 service interfaces are also available for integrators and installers. ### Is a single MPPT tracker in the IGRID-VX-IV sufficient for my roof? A single MPPT (Maximum Power Point Tracking) system is suitable for simple, single- or two-pitched roofs, where all panels have the same orientation and angle of inclination. If the installation includes areas facing different directions, a pitched roof with dormers, or areas with partial shading, it is advisable to consider an inverter with two MPPT trackers. This is because shading in one section with a single MPPT can reduce the performance of the entire string. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/Easun-IGrid-VX-IV-5-6KW-Wifi-Manual-EN-V1-0-eac39dc2c6d3.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Easun Power ISOLAR-SMX-II-5.6KP-WIFI](https://comparepv.com/inverter/easun-power-isolar-smx-ii-5-6kp-wifi) | 5.6 kW | | 1 | 10.5 kg | Similar on paper | | [Easun Power LSOLAR SML-II-5.6KW](https://comparepv.com/inverter/easun-power-lsolar-sml-ii-5-6kw) | 5.6 kW | | 1 | 12.0 kg | 1.5 kg heavier | | [Easun Power ISolar SMV IV 5600-48](https://comparepv.com/inverter/easun-power-isolar-smv-iv-5600-48) | 5.6 kW | | | | Similar on paper | | [Easun Power ISolar SMG II 5.6KW](https://comparepv.com/inverter/easun-power-isolar-smg-ii-5-6kw) | 5.6 kW | | | 10.0 kg | Similar on paper | | [Easun Power ISolar SMG II 5.6KP](https://comparepv.com/inverter/easun-power-isolar-smg-ii-5-6kp) | 5.6 kW | | | 10.0 kg | Similar on paper | | [Easun Power ISolar-SMX-II-5.6KW](https://comparepv.com/inverter/easun-power-isolar-smx-ii-5-6kw) | 5.6 kW | | | 10.9 kg | Similar on paper | | [Easun Power ISolar SMR II 5.5KW](https://comparepv.com/inverter/easun-power-isolar-smr-ii-5-5kw) | 5.5 kW | | | 12.1 kg | 1.6 kg heavier | | [PowMr POW-HVM5.5K-48V-LIP](https://comparepv.com/inverter/powmr-pow-hvm5-5k-48v-lip) | 5.5 kW | | | 9.9 kg | Similar on paper | --- Source: https://comparepv.com/inverter/easun-power-igrid-vx-iv-5-6kw-wifi
