HUIZHOU, CHINA — BSLBATT, a top company in lithium iron phosphate energy storage that operates in over 100 countries, today announced that the M-Power S30/69 is now available for purchase. This is a high-quality mobile energy storage system designed to replace diesel generators in emergency response, construction, broadcasting, event power, and mobile EV charging.
"The M-Power S30/69 is our answer to a question the industry has been asking for years: when can we finally have a diesel replacement that actually works in the field — not just in a brochure? This is it."

The Problem This Product Solves
Diesel generators have long been the only practical option for high-power, off-grid energy in demanding environments. But they carry a growing list of costs that operators can no longer ignore:
- Fuel costs that compound unpredictably over project lifetimes
- Noise levels that restrict operation in urban sites, hospitals, schools, and events
- Exhaust emissions that violate increasingly strict local environmental regulations
- Maintenance-intensive engines that fail at the worst possible moments
- Zero renewable integration — every kilowatt-hour must be purchased as fuel
The M-Power S30/69 eliminates every one of these constraints.
What the M-Power S30/69 Delivers
At its core, the M-Power S30/69 is a self-contained 30 kW hybrid inverter plus a 69 kWh LiFePO₄ battery housed in a single ruggedized IP55-rated enclosure. It charges from solar PV, the utility grid, or both simultaneously — and discharges at full 1C rate to meet peak power demands on any job site.
Four Core Capabilities
- Silent, zero-emission output:· 30 kW continuous · 110% overload continuous · 120% for 1 minute
- Dual MPPT solar input: 19.2 kW + 19.2 kW — up to 38.4 kW combined solar harvest
- Flexible AC and DC output: Three-phase 400V / single-phase 230V AC + 125A DC port for mobile EV charging
- Modular expansion: Up to 3 units in parallel — 90 kW / 207 kWh mobile microgrid
30% more space-efficient than equivalent diesel + UPS combinations of the same rated output — with a significantly smaller installation footprint.
Who Is This Mobile ESS Built For?
Emergency Response & Disaster Recovery
When grid power fails after a hurricane, flood, or earthquake, the M-Power S30/69 deploys in minutes to power field hospitals, command centers, communication towers, and water treatment equipment. Its IP55 enclosure handles rain, dust, and rough handling. Its silent operation keeps responders focused. Its solar input eliminates dependence on fuel supply chains — precisely when fuel supply chains are most likely to be disrupted.
Construction & Industrial Sites
Construction sites in urban environments face growing restrictions on diesel engine use. The M-Power S30/69 powers electric tools, welding equipment, lighting arrays, and site offices with zero exhaust, zero noise complaints, and zero permit violations. With 69 kWh on board, a typical light-industrial site can run a full 8-hour shift without recharging.
Broadcast, Events & Film Production
Broadcast trucks, live event stages, and film sets have long suffered through diesel generators running just meters from microphones and cameras. The M-Power S30/69 delivers broadcast-grade stable power — silently. No generator noise on the soundtrack. No exhaust near talent. No fuel deliveries disrupting the shoot.
Mobile EV Charging
The M-Power S30/69 includes a 125A DC charging port alongside three 125A three-phase AC quick connectors, making it an immediately deployable mobile EV charging hub for fleet operators, event parking, highway emergency charging, or any location where permanent EV infrastructure has not yet been installed.
Remote & Off-Grid Operations
Mining exploration teams, telecom tower maintenance crews, scientific research stations, and military forward operating bases all share a common challenge: they need reliable high-power energy in locations that have no grid connection and limited fuel resupply capability. The M-Power S30/69 — particularly when combined with a solar array — provides a multi-day autonomous power supply that removes this operational constraint.
