This simplifies the design and installation of off-grid systems compared to modular solutions (e.g., a separate Victron BlueSolar MPPT + inverter). - **Dual MPPT (2 x 80A in the 5 kW variant)** - The 5 kW variant offers two independent MPPT (Maximum Power Point Tracking) strings, each with a maximum current of 80 A, allowing for the connection of PV (photovoltaic) strings with different orientations or inclines without incurring losses due to uneven shading. This is a key feature in the small off-grid hybrid category, where many competitors only offer a single MPPT string. - **Compatibility with lithium batteries** - The series supports both lead-acid and lithium (Li-ion/LiFePO4) batteries, including a function for activating lithium batteries. This allows for upgrading the energy storage system without replacing the inverter. - **Short UPS switching time (~10 ms)** - Users in independent tests conducted on the DIY Solar forum reported a typical switching time of approximately 10 ms, which falls within the acceptable range for most electronic devices and makes the series suitable for providing backup power to sensitive receivers (routers, NAS devices, and low-end medical equipment). - **CE certification and Wi-Fi monitoring** - Confirmed compliance with EU market requirements (CE certification) simplifies legal implementation in installations across Europe. The built-in Wi-Fi module and mobile application enable remote monitoring of parameters and configuration changes without the RS-232 cable. ### Cons - **The product line has been discontinued.** - ISolar MLV is marked as discontinued - Easun Power confirms that production of this line has ended. Availability of original spare parts and service support is limited; the manufacturer indicates an email address as the only channel for assistance for users of discontinued models, without guaranteed turnaround times or availability of parts. - **Inverter efficiency ≤92% - below the top tier** - The declared efficiency in inverter mode is above 92%, while competing premium-class devices (e.g., Victron MultiPlus-II ~95%, Studer XTH ~96%) achieve significantly higher values. In systems operating 365 days a year, the difference of 3-4% translates into actual energy losses of tens of kWh per year. - **Warranty is only 12 months** - The standard manufacturer warranty is 1 year, while comparable competitors offer 2-5 years (Victron Energy offers 5 years, Growatt offers 5 years, and Deye offers 5 years). For installations with a planned lifespan of 10+ years, this means a significantly higher risk of repair costs after the warranty period expires, especially given the discontinued status. ## About this series The Easun Power ISolar MLV series are compact off-grid/hybrid all-in-one solutions integrating a pure sine wave inverter, MPPT charge controller, and battery charger into one unit. They serve as the core of backup power systems (UPS), cabinetry, workshops, campers, and microgrids where grid independence or generator integration is key. Depending on the variant, the series features dual MPPT, simplifying PV system design for rooftop panels across different tilts and enhancing energy yield under partial shading. High efficiency (even in typical European conditions) minimizes daily losses and delivers genuinely higher annual energy production. Added benefits include an intuitive LCD configuration interface and integration with monitoring via Wi-Fi and mobile app. The ISolar MLV works with energy storage systems, including lithium batteries, with CE certification confirming compliance with EU market requirements.

The ISolar MLV series has been discontinued by Easun Power and is no longer offered as a new product. However, some units may still be available from distributors as part of their existing stock. Before purchasing, it is advisable to check the availability of spare parts and technical support. As an alternative, consider newer series from this manufacturer, such as the ISolar SMV or ISolar MLV-U. ### Can the Easun Power ISolar MLV inverter be connected to LiFePO4 batteries? Yes, the ISolar MLV series is compatible with lithium batteries, including the popular LiFePO4 type. The inverter allows for configuring charging parameters (voltage, current, mode) tailored to lithium chemistry. This enables the creation of a complete energy storage system using both AGM/lead-acid batteries and modern lithium batteries. ### What is the warranty on Easun Power ISolar MLV inverters? Easun Power provides a 12-month manufacturer's warranty for the ISolar MLV series and offers after-sales support throughout the device's lifespan. It is important to note that this series is no longer in production, which may affect the availability of service and original spare parts in the long term. ### Does the Easun Power ISolar MLV function as an uninterruptible power supply (UPS) when the main power supply fails? Yes, the ISolar MLV functions as a UPS (Uninterruptible Power Supply). It automatically switches to battery power when the mains voltage drops or decreases significantly. The device provides a clean sinusoidal waveform, making it suitable for powering sensitive electronic equipment, pumps, or tools that require a stable voltage. ### What is the efficiency of the ISolar MLV inverter, and does it perform well in the Polish climate? The ISolar MLV inverter achieves a conversion efficiency of 92-96% depending on the power version. The device operates within a temperature range of -15°C to +55°C, making it perfectly suitable for the Polish climate, including cold winters. High efficiency under partial shading is supported by an MPPT controller with a tracking efficiency of 99.9%. ### Does the Easun Power ISolar MLV inverter support dual MPPT, and what does this mean in practice? Selected variants of the ISolar MLV series feature a dual MPPT tracker. In practice, this allows you to connect solar panels from two different roof sections or with different orientations as separate strings, which reduces losses due to partial shading of one group. For residential installations with a gable roof, this translates to a significantly higher energy yield during the day. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/MLV-5KW-U-20b7d4b76926.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt SPF 5000 ES](https://comparepv.com/inverter/growatt-spf-5000-es) | 5 kW | | 1 | 12.0 kg | Similar on paper | | [Growatt SPF 5000T DVM](https://comparepv.com/inverter/growatt-spf-5000t-dvm) | 5 kW | | | 47.0 kg | Similar on paper | | [Growatt SPF 5000T DVM-MPV](https://comparepv.com/inverter/growatt-spf-5000t-dvm-mpv) | 5 kW | | | 47.0 kg | Similar on paper | | [Growatt SPF 3500 ES Lite](https://comparepv.com/inverter/growatt-spf-3500-es-lite) | 5 kW | | 1 | 9.2 kg | Similar on paper | | [Growatt SPF 5000 ES Lite](https://comparepv.com/inverter/growatt-spf-5000-es-lite) | 5 kW | | 1 | 9.8 kg | Similar on paper | | [Growatt SPF 5000TL HVM](https://comparepv.com/inverter/growatt-spf-5000tl-hvm) | 5 kW | | | 11.5 kg | Similar on paper | | [Ginlong Solis S6-EO1P5K-48](https://comparepv.com/inverter/ginlong-solis-s6-eo1p5k-48) | 5 kW | | 1 | 13.8 kg | Similar on paper | | [Easun Power SMP-5KW](https://comparepv.com/inverter/easun-power-smp-5kw) | 5 kW | | | 12.0 kg | Similar on paper | --- Source: https://comparepv.com/inverter/easun-power-isolar-mlv-5kw-u
