Product Overview

The EnerCube Mini e-Storage is a residential and commercial Battery Energy Storage System (BESS) by Enertech, offering single-phase power ranging from 5kWh to 20kWh. It uses lithium-ion LFP batteries for safety, reliability, and performance. The plug-and-play design makes it ideal for homes and small businesses needing power backup. It features a built-in inverter and MPPT solar charger, supporting both DC solar charging and AC charging from the grid or generator. The system is modular and expandable in 5kW/5kWh steps up to 5kW/20kWh. It delivers over 94% DC efficiency with pure sine wave output and a 10ms transfer time. Three models are available: 3kW/5kWh, 5kW/10kWh, and 10kW/20kWh. The cabinet-style enclosure (IP21) uses natural air cooling and supports RS485/Wi-Fi monitoring. Batteries are rated for 4000 cycles at 80% DOD with 90% depth of discharge. The system supports off-grid operation with solar and allows priority settings for grid, solar, and battery. Manufactured by Enertech — recognized by DSIR, Govt. of India — with 30 years of R&D experience and 20,000+ global installations.

Why EnerCube Mini Transforms Energy Management

sr 1 1 1
Modular 3kW/5kWh, 5kW/10kWh, 10kW/20kWh Building Blocks

Choose the capacity that fits your needs today and expand effortlessly as your energy demands grow. The EnerCube Mini e-Storage is designed as a modular, easily expandable system — simply add energy modules in steps of 5kW/5kWh, scaling from 5kWh all the way up to 20kWh.

sr 1 2 1
Dual Charging Flexibility

Charge from solar panels via integrated MPPT controllers during the day, and from grid or diesel generator at night or during extended cloudy periods. Intelligent charging algorithms maximize battery life while ensuring you're always ready for grid outages.

sr 1 3 1
LiFePO4 Battery Technology

Premium lithium iron phosphate (LFP) chemistry delivers the highest levels of safety, performance, and longevity. Unlike other lithium chemistries, LFP cells resist thermal runaway, operate safely across extreme temperatures, and maintain consistent performance through 6,000+ charge cycles—that's over 15 years of daily cycling.

sr 1 4 1
True Plug-and-Play Installation

Pre-wired, pre-programmed, and factory-tested. Your installer connects solar input, AC power, and loads—typically completing installation in under 4 hours. No complex programming, no specialized training, no expensive commissioning required.

sr 1 5 1
Intelligent Energy Management

Built-in EMS optimizes energy flow based on solar generation, battery state of charge, grid availability, and load demand. Prioritize self-consumption, implement time-of-use strategies, or configure backup power modes—all through intuitive smartphone app control.

Intelligent Operating Modes

why choose 1
Self-Consumption Mode (Peak Shaving)

Maximize solar utilization by storing excess daytime generation for evening/night use. Minimize grid imports during high-tariff periods, reducing electricity bills by 40-70%.

price 1 3
Backup Power Mode

Seamless transition to battery power during grid outages. Critical loads remain powered for hours or days depending on system size and load profile. Automatic grid reconnection when power returns.

why choose 3
Time-of-Use Optimization

Charge batteries during off-peak low-tariff hours, discharge during peak high-tariff periods. Arbitrage electricity pricing even without solar panels, reducing monthly energy costs by 30-50%.

why choose 3
Hybrid Solar + Grid Mode

Combine solar, battery, and grid power intelligently based on availability and cost. Solar powers loads first, battery supplements when solar is insufficient, grid provides backup during extended cloudy periods.

why choose 3
Off-Grid Mode
