Overview & Key Features

The Evi 20000VA/18000W is a high-capacity, true online double-conversion UPS designed for mission-critical applications in data centers, industrial settings, large server rooms, and telecommunications infrastructure.

• Capacity: 20,000 VA / 18,000 Watts. The difference between VA (Volt-Amps) and W (Watts) is the Power Factor (PF). Here, PF = 18,000W / 20,000VA = 0.9. This means it can efficiently support modern server power supplies which have a high power factor.

• Topology: Online Double Conversion. This is the highest level of power protection. It continuously converts AC power to DC (to charge the batteries) and then back to clean, stable AC power (to run the equipment). This provides complete isolation from all utility power problems like blackouts, sags, surges, spikes, and frequency variations.

• Form Factor: Tower. This is a free-standing unit, like a large server cabinet. It’s often placed on the data center floor. Many tower models can be converted to a rack-mount configuration with an optional kit.

• Input/Output Phases: 3-Phase Input, 3-Phase Output. It connects to a 3-phase electrical supply (common in commercial/industrial buildings) and provides a 3-phase output to distribute the load across multiple branches.

Key Specs / Features

What These Mean in Practice

• Because it’s an online double-conversion UPS, there’s zero transfer time when utility power fails; the load is always powered through the inverter so power is continuous and clean. This is good for sensitive equipment.

• The wide input voltage (208-478 VAC) and frequency tolerance mean it handles unstable grid/generator power better.

• The power factor of about 0.9 means you can load it up to 18 kW (real power) even though it’s rated 20 kVA.

• Parallel / redundant capability makes it suitable for data centres or high-availability environments: if one unit fails or is under maintenance, others can carry the load.

• The option to add external battery banks gives flexibility in runtime during outages.

Things to Check / Consider

Before purchasing or installing, you may want to confirm:

1. Exact output voltage aligned with your region’s 3-phase standard (e.g. 380V, 400V, 415V)

2. Runtime at full load, to ensure it meets required backup duration

3. Battery maintenance / replacement costs

4. Space & ventilation — given its size and power, good airflow is needed

5. Cooling — whether ambient temp will stay within spec, or if extra AC is needed

6. Load type (especially non-linear loads) since harmonics or exceeding crest factor may affect performance.

7. Service / support availability locally for parts, battery, repairs.
