Description
The VMS-V-2.2K-12 is a 1,600W off grid hybrid solar inverter engineered for standalone solar power systems where mains grid connection is unavailable or impractical. It accepts a wide PV input range of 40–400Vdc — covering a broad variety of solar panel string configurations — and delivers a clean pure sine wave output at 220/230VAC on 50Hz or 60Hz, matching regional power standards across most global markets.
With a maximum load capacity of 2,400W, it provides meaningful surge headroom above its 1,600W rated power — an important practical advantage when motor-driven loads such as refrigerator compressors, water pumps, or fans draw a higher current spike on startup before settling to their running load.
The selectable voltage range gives installers precise load-compatibility control: 70–280VAC for personal computers, and 90–280VAC for home appliances — protecting both sensitive electronics and standard household equipment from voltage tolerance issues on the same installation, without requiring additional regulation hardware.
Housed in an ultra-compact 348×270×95mm enclosure and weighing just 4kg, the VMS-V-2.2K-12 is the most portable inverter in the VMS range — easily transported to remote and off-grid sites and installed on a standard wall bracket by a single engineer. It is well suited to small rural homes, agricultural outbuildings, holiday cabins, island properties, and any off-grid application requiring reliable, appliance-safe power from solar. Operating temperature -10°C to +50°C, storage -15°C to +60°C, humidity 5%–95% relative humidity (non-condensing).

Key features
- True off-grid operation — no mains connection needed
Runs entirely from solar PV and battery storage. Purpose-built for rural homes, island sites, agricultural buildings, remote cabins, and locations where grid connection is unavailable or too costly to install.
- Wide PV input — 40 to 400Vdc
Accepts a broad solar string voltage range — eliminates the need for a separate MPPT charge controller, simplifying system design and reducing overall installation cost and component count.
- 2,400W max load — surge headroom above rated power
Rated at 1,600W continuous but sustains up to 2,400W peak — essential for starting motor loads such as refrigerator compressors, water pumps, and fans that draw higher current on startup before settling to running load.
- Pure sine wave — 220/230VAC output
Outputs grid-equivalent pure sine wave power at 220 or 230VAC — fully compatible with all household appliances, power tools, computers, and sensitive electronics. No appliance restrictions from waveform distortion.
- Selectable voltage range — PC and appliance modes
70–280VAC for personal computers, 90–280VAC for home appliances — configurable per installation to protect both sensitive and standard loads simultaneously without additional voltage regulation equipment.
- Ultra-compact and portable — 348×270×95mm / 4kg
At just 4kg and 95mm deep, it is the most portable model in the VMS range. Easily transported to remote sites in a vehicle or on foot, and installable by a single engineer on a standard wall bracket — no specialist lifting or rigging required.
- Dual frequency — 50Hz and 60Hz
Operates on both 50Hz and 60Hz, making it compatible with solar systems across Africa, the Middle East, Europe, Asia, and the Americas — no region-specific variant required.
