60kW 125kWh LiFePO4 Mobile Energy
Storage System with 108kW Solar Input
The BSLBATT M-Power S60/125 is a 60kW/125kWh mobile energy storage system built around a lithium iron phosphate (LiFePO4) battery pack for temporary and off-grid power. It integrates a 60kW hybrid inverter, 125kWh LFP battery, and 108kW solar input with 4 MPPT trackers in a single IP55-rated enclosure weighing 1,500 kg. The system delivers three-phase and single-phase AC output, charges from solar, grid, diesel generators, or DC charging stations, and pairs with diesel generators in hybrid mode to cut fuel use by up to 60%. Two units connect in parallel for 120kW/250kWh. Designed for construction sites, mining operations, outdoor events, emergency response, and remote industrial projects.
60kW Continuous Power with 108kW Solar Charging
The M-Power S60/125 delivers 60kW of continuous three-phase AC power, enough to run welding equipment, tower cranes, LED screens, telecom base stations, and water purification units simultaneously. Its 125kWh LiFePO4 battery pack provides over two hours of full-load runtime and considerably longer at typical partial loads.
What sets this system apart is its integrated 108kW solar input across 4 MPPT trackers. This is the highest PV capacity in its power class. On a clear day with adequate panel area, the solar array alone can fully recharge the battery while continuing to serve the load. In off-grid mining or construction deployments with consistent sun exposure, this translates to dramatically reduced or eliminated dependence on fuel delivery logistics.

Four-Source Charging for Any Deployment Scenario
The M-Power S60/125 accepts power from four independent sources: solar panels (108kW DC), grid connection (AC), diesel generators, and DC charging stations. No other mobile BESS in this power class combines all four charging methods in a single unit.
This flexibility matters in practice. A construction team in an urban area can charge from the grid overnight and run clean power during the day. A mining operation 200 km from the nearest grid connection can pair the unit with solar panels and a diesel backup. An event organizer can pre-charge at a depot via DC fast charging, then deploy a fully charged unit to the venue with zero on-site emissions. The system's built-in energy management automatically prioritizes the lowest-cost source and switches between inputs without manual intervention.
IP55 Outdoor Protection in a Transportable 1,500 kg Package
At 1,550 × 1,200 × 1,300 mm and 1,500 kg, the S60/125 is compact enough for standard forklift handling and flatbed transport, yet large enough to house a full 125kWh LFP battery with integrated inverter, BMS, EMS, and optional fire suppression.
The IP55-rated steel enclosure protects all internal components against dust ingress and water jets from any direction. It operates across a temperature range of -20°C to 55°C (with derating above 45°C) and at altitudes up to 3,000 m (with derating above 2,000 m). Intelligent air cooling maintains optimal battery temperature without the complexity and maintenance demands of liquid cooling. The result is a unit that can be deployed to a desert oil field, a tropical construction site, or a Scandinavian winter event without modification.
Diesel Generator Hybrid Mode: Cut Fuel Use Without Replacing Your Fleet
The S60/125 is not a forced replacement for diesel generators. It is designed to work alongside them. In hybrid mode, the battery handles base loads and peak demands while the generator runs only at optimal load points. This approach reduces fuel use by up to 60%, extends generator service life, and cuts maintenance intervals.
The system's overload capacity (110% continuous, 140% for 10 seconds) handles startup surges from heavy equipment without tripping. During low-load periods, especially overnight on 24-hour sites, the battery takes over entirely and the generator shuts down, eliminating noise and emissions during rest hours.
For operations that are ready to go fully electric, the S60/125 runs independently on battery and solar power alone, producing zero tailpipe emissions.
Parallel to 120kW / 250kWh for Larger Sites
Two M-Power S60/125 units connect in parallel to deliver 120kW of continuous power and 250kWh of usable energy. The parallel configuration uses automatic load balancing across both units, with no external controller required.
This scalability covers the range from single-unit deployments (60kW for small-to-mid construction sites, film sets, or telecom backup) to dual-unit configurations (120kW for large events, mining camp base loads, or emergency grid support). Rather than purchasing a single large system, operators can start with one unit and add a second when project demands grow.
Where the M-Power S60/125 Replaces Diesel
Equipment Rental Companies
Rental fleets adding battery-powered units to meet growing customer demand for clean, quiet temporary power. The S60/125's five-year warranty and low maintenance requirements (no oil changes, no fuel filters, no exhaust treatment) support higher rental margins compared to equivalent diesel generators.
Construction & Engineering Firms
Job site power in cities with noise restrictions and low-emission zones. The system provides clean daytime power from battery and solar, with diesel hybrid backup for extended or high-demand periods. On 24-hour sites, the battery handles overnight loads silently while the generator rests.
Event Production & Film Companies
Silent power for stages, lighting rigs, broadcast equipment, and catering. The S60/125 operates significantly quieter than diesel generators, eliminating the constant noise floor that disrupts performers, audiences, and recording equipment.
Mining & Oil Field Operators
Remote operations that depend on diesel generators where fuel transport is the largest single operating expense. Pairing the S60/125 with solar panels and an existing generator reduces fuel logistics and costs while extending generator service intervals.
Emergency Response Organizations
Rapid-deployment power for field hospitals, water treatment, communication equipment, and temporary shelters. The system charges from any available source and operates immediately upon delivery.
Optional 20kW DC Forklift Charger
The M-Power S60/125 can be equipped with an optional 20kW DC charging module that charges forklift batteries directly from the unit. This is particularly relevant for construction and warehousing sites where electric forklifts operate alongside the main power load. The charger connects via a 125A DC charging socket and eliminates the need for a separate charging station on site.
