Description
The VMS-V-4.2K-24H is a 4,200W on/off grid hybrid solar inverter designed for small to medium residential installations. It delivers a clean pure sine wave output at 220/230/240VAC, making it fully compatible with household appliances, computers, and sensitive electronics.
Operating on a 50Hz or 60Hz frequency, it supports a selectable voltage range of 170–280VAC for personal computers and 90–280VAC for home appliances, giving installers precise load compatibility control. The feed-in grid voltage range is 195–253VAC, with a grid frequency tolerance of 49–51±1Hz / 59–61±1Hz, ensuring stable grid interaction in regions with variable supply quality.
With a maximum load of 4,200W, this model suits a typical household with moderate energy consumption. It weighs 8.5kg and shares the compact 147×432×553mm enclosure across the VMS range, fitting standard wall-mount installations in utility rooms or garages. Operating temperature is -10°C to +50°C, with storage rated to -15°C to +60°C and humidity tolerance of 5%–95% (non-condensing).

Key features
- True on/off grid hybrid switching
Seamlessly prioritises solar, falls back to battery, then grid — no manual switching required. Works as a grid-tied backup system or a fully independent off-grid solution.
- Pure sine wave — 220/230/240VAC
Outputs grid-quality pure sine wave power safe for all appliances including computers, motors, medical equipment, and audio electronics — not limited to simple resistive loads.
- Selectable voltage range per load type
170–280VAC for PCs, 90–280VAC for home appliances — configurable per installation without additional regulation equipment.
- Wide grid compatibility — 195–253VAC / 49–51±1Hz
Tolerates grid voltage and frequency fluctuations common in developing markets and regions with variable supply quality, reducing nuisance disconnections.
- 4,200W continuous load — ideal for small homes
Comfortably powers a typical household load including refrigerator, lighting, fans, TV, and computer equipment running simultaneously without overloading.
- Compact wall-mount — 147×432×553mm / 8.5kg
Slim form factor fits standard wall-mount brackets in utility rooms and garages. Lightest model in the On/Off Grid range at 8.5kg — straightforward single-engineer installation.
