Mecer 3kVA 2400W Line-Interactive UPS with 4× 9Ah Batteries
R5 980.00 incl. VAT
The Mecer 3kVA (2,400W) Line-Interactive UPS is South Africa’s most popular office and home office UPS — providing instant power protection for computers, NAS drives, networking equipment, and critical appliances during load shedding and power surges. Line-interactive topology provides automatic voltage regulation (AVR) for SA’s notoriously unstable grid, correcting sags and swells without switching to battery.
Includes 4 × 9Ah sealed lead-acid batteries for 20–40 minutes of runtime at 50% load. Pure sine wave output protects sensitive electronics. 8 × IEC output sockets. USB monitoring port with ShutDown Manager software for graceful computer shutdown during extended outages.
Mecer is South Africa’s leading UPS brand — local warranty support, readily available replacement batteries, and nationwide service network. Price excludes VAT.

What Is the Mecer 3kVA Line-Interactive UPS?
The Mecer 3kVA is a line-interactive uninterruptible power supply (UPS) providing 2,400W of protected output power for office and home environments. “Line-interactive” means the UPS actively regulates incoming voltage — boosting low voltages and trimming high voltages using its AVR (Automatic Voltage Regulation) circuitry — without draining the battery. Only when the grid fails completely does it switch to battery, extending battery life significantly compared to standby (offline) UPS designs.

Automatic Voltage Regulation for SA’s Grid
South Africa’s electricity grid is prone to voltage fluctuations — particularly in townships, rural areas, and during periods of high demand. Voltage sags (below 207V) can cause computers to restart, hard drives to fail, and sensitive electronics to malfunction. The Mecer 3kVA’s AVR circuitry corrects input voltages from 140V–290V to a stable 230V output — protecting your equipment even when the UPS isn’t on battery.
Who Needs This UPS?
Ideal for: home offices with 2–4 computers and monitors; small business server rooms; retail point-of-sale systems; network equipment rooms (switches, routers, NAS); and any application where data loss during a power cut would cause business disruption. The 25-minute battery runtime at 1,200W load gives you enough time to save work and gracefully shut down systems during an unscheduled outage.
Easy Battery Replacement
The Mecer 3kVA uses industry-standard 12V 9Ah batteries — widely available from PowerVault and all major battery suppliers in SA. Battery replacement is a user-serviceable task taking approximately 10 minutes. Replacement batteries typically cost R200–R350 each, making the lifetime cost of ownership very low.

Johannes Mokoena –
The Mecer 3kVA 2400W Line-Interactive UPS with 4× 9Ah Batteries is very well built and arrived well packaged from PowerVault. Installation was simple with the clear wiring diagram. We now have enough storage to run through the night on solar alone during summer. Battery has been rock solid.

Added the Mecer 3kVA 2400W Line-Interactive UPS with 4× 9Ah Batteries to expand our backup capacity and the difference is night and day. We now get through extended Stage 6 outages with power to spare. The battery management system keeps everything safe and the unit runs cool. Excellent product.
