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.

Pros and cons
The series combines a pure sine wave inverter, an MPPT controller, and a battery charger in a single enclosure, eliminating the need for separate devices and wiring between them. This simplifies the design and installation of off-grid systems compared to modular solutions (e.g., a separate Victron BlueSolar MPPT + inverter).
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.
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.
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).
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.
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.
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.
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.
