EnerTech Battery Charger Cum Discharger: The Ultimate Power Solution
Industrial battery banks represent a substantial capital investment, serving as the last line of defense in substations, power plants, telecom hubs, and defense installations. However, without regular diagnostic discharge testing and precision charging, dormant battery degradation goes unnoticed until a grid blackout occurs. An Industrial Battery Charger cum Discharger combines high-performance multi-stage charging, controlled capacity testing (deep discharge), and automatic recovery charging into a single, automated, dual-mode system.

When it comes to industrial power solutions, reliability, efficiency, and versatility are key. The EnerTech Battery Charger Cum Discharger stands out from the competition by integrating cutting-edge technology and superior design. Here’s why this type of industrial battery charger is essential:


High-speed DSP control manages both the charging bridge and the electronic discharge chopper, preventing voltage undershoot or thermal stress on battery terminals.


Automated multi-point cut-offs protect against deep over-discharge, reverse polarity, thermal runaway, cell reversal, and AC/DC ground faults.


Advanced filtering ensures smooth DC current absorption and delivery, safeguarding the internal active material of battery plates and doubling battery operational life.


Modbus, SNMP, and CAN communication protocols provide automated test reporting, real-time Ah discharge graphs, and predictive health diagnostics directly to central control rooms.


EnerTech offers regenerative topologies that convert discharged DC power back into clean AC electricity to power facility equipment, cutting testing energy costs.


EnerTech maintains full galvanic isolation and redundant DC bus support so plant control systems remain 100% protected throughout the entire test cycle.


Available in custom DC voltage ranges (24V, 48V, 110V, 220V, up to 750V DC), custom discharge current rates (up to 1000A+), and rugged enclosure ingress ratings (IP20 to IP55) tailored to exact site constraints.
Delivering success through 35,000+ satisfied customers over the past 35+ years with our impeccable Battery Energy Storage System Installation.
Trusted by industries, businesses, and institutions for reliable solar and energy storage solutions. Proven performance backed by decades of engineering excellence and customer confidence.
Unlike conventional chargers, the EnerTech Charger Cum Discharger offers dual functionality — it both charges your battery bank and discharges power to the load or grid, all in one unit.
It is suitable for charging both nickel-cadmium and lead-acid batteries, while also being capable of functioning as a direct power supply even without batteries.
Yes — it is built for the harshest industrial conditions using a three-phase, three-level conversion bridge combining advanced thyristor and IGBT technologies for superior durability and performance.
It is widely used in telecom towers, oil and gas remote monitoring systems, underground mining backup power, and railway signaling systems requiring uninterrupted and reliable power.
