About This Service

Power cuts remain a reality across Indian industry. A properly designed inverter and battery system ensures your operations — whether a factory production line, a commercial office, or a residential home — continue without interruption regardless of how long the grid is down.

WAA Power supplies, installs, and maintains inverter-battery systems for every scale: from 500 VA home systems to 200 kVA three-phase industrial backup systems. We help clients select the right battery technology (VRLA, tubular, or lithium-ion) and inverter topology for their specific load, runtime requirement, and budget.

Key Benefits

Pure sine wave output compatible with all sensitive electronic equipment
Lithium-ion option offers 3x the cycle life of VRLA at lower maintenance
Intelligent charging extends battery life significantly
Scalable battery banks allow runtime extension without replacing the inverter
AMC programmes include periodic health checks and proactive replacement

How It Works

01

Load Assessment

We calculate your critical load — what must stay on during a power cut — and determine the required inverter kVA and battery Ah capacity.

02

System Selection

Appropriate inverter topology (pure sine wave, offline, or online) and battery technology are selected based on load sensitivity and runtime requirement.

03

Installation

Inverter and battery bank installation with proper cable sizing, fusing, and earthing as per electrical standards.

04

Monitoring & AMC

Battery health monitoring, periodic equalisation charging, and preventive maintenance under AMC contract.
