Rebelvolt is a Finnish energy technology company providing battery based mobile power systems as a clean, silent, and reliable alternative to diesel generators. Our systems are used across defence, construction, rental, industrial, and event sectors.

An e-Generator is Rebelvolt’s battery based power system designed to replace diesel generators. It delivers reliable AC and DC power, is silent, emission free, and reduces fuel logistics, maintenance, and operational risks.

Rebelvolt offers mobile power systems including portable units, trailers, palletized systems, and containerized solutions. They cover a wide range of power and capacity requirements for both temporary and semi-permanent deployments.

Rebelvolt products are scalable from small portable units delivering 10 kilowatts of continuous power to large trailers and containers providing tens of kilowatts and up to 200 kilowatt-hours. Systems can be combined for larger installations as needed

Runtime depends on your equipment’s power consumption. For example, a 20 kW load can run for approximately 10 hours continuously on a 200 kWh system. Runtime scales proportionally with load and system size.

Yes. Rebelvolt uses LiFePO4 chemistry, which is inherently safer than many other lithium chemistries. It offers high cycle life, thermal stability, and minimal risk of thermal runaway.

All Rebelvolt systems are designed and manufactured in Finland, ensuring high quality, local engineering support, and stringent testing standards.

Yes. Rebelvolt products used in defence applications can be supplied with NATO stock numbers and related codes to support logistics and procurement.

Rebelvolt systems operate reliably in temperatures from -35°C to +50°C. They are designed for harsh climates, including cold field operations and hot industrial environments.

Using Rebelvolt systems alongside diesel generators allows you to reduce runtime on the generator, cutting fuel consumption by up to 70 percent. The Rebelvolt e‑Generator controls the diesel generator on and off based on battery charge status, so the generator only runs when it is charging the battery, operating at its optimal power level and efficiency. This setup also reduces noise and emissions, lowers maintenance needs, and provides more stable power, especially for sensitive equipment.

Yes. Rebelvolt can develop tailor-made solutions to meet specific operational or site requirements. Custom designs can include specific power output, form factor, environmental protection, or mobility needs.

Yes. Rebelvolt can integrate its battery systems into larger setups. For example, a container can house your equipment with Rebelvolt batteries integrated inside to provide all the power needed. This creates a turnkey, plug-and-use solution where your equipment is powered directly by our battery system, fully managed and monitored.

Rebelvolt systems are designed for low maintenance. Routine checks include monitoring battery status, ensuring connections are secure, and following recommended inspection schedules. There is no fuel handling or engine maintenance like with diesel generators.

Rebelvolt systems can be charged from standard AC power, generator, or compatible renewable sources. Charging time depends on system size and charger type. For example, a trailer system can reach full capacity in 2–8 hours with a fast charger.

Rebelvolt LiFePO4 batteries have a long cycle life, typically over 6,000 full charge cycles. Standard warranty covers both the battery and the system for up to 2 years, depending on the product and application.

Yes. Rebelvolt systems can be charged using solar panels, wind turbines, or other renewable sources, either directly or through standard grid connections, allowing hybrid setups and flexible energy management.

Yes. Rebelvolt systems can operate as uninterruptible or backup power sources. They provide seamless support to critical equipment during grid outages, minimizing downtime and operational disruption.

Rebelvolt stands out through modular design, rugged performance, fast deployment, silent operation, and integrated energy management. Our solutions reduce fuel logistics, maintenance, and environmental impact while delivering reliable high power in harsh conditions. They are proven in defence, construction, rental, and industrial use.

Rebelvolt solves common power challenges such as noise, emissions, fuel logistics, and generator reliability. They enable uninterrupted operations, reduce operational costs, and simplify power management, whether on a construction site, in a rental fleet, or in field defence operations.

Yes. Systems are engineered for extreme conditions including temperature variations, vibration, and mobile deployment. They are proven to perform in demanding environments and support mission critical operations.

Rebelvolt systems are plug and use, designed for rapid setup with minimal training. They can be quickly moved and installed in minutes wherever power is needed.

Yes. They are designed to deliver high power output comparable to diesel generators while eliminating noise, emissions, and fuel logistics. Suitable for both temporary and longer term applications.

Yes. Rebelvolt systems are modular and can be scaled to meet the power requirements of small units, mobile bases, construction sites, or larger industrial operations.

All systems include integrated monitoring and diagnostics. Operators can track performance remotely, schedule maintenance proactively, and ensure reliable operation at all times.

Absolutely. By reducing fuel consumption, emissions, and noise, Rebelvolt systems support sustainability goals and reduce environmental impact compared to diesel generators.

Rebelvolt solutions are operational in defence, construction, rental, industrial, and event sectors, with proven performance in harsh and mobile applications.

Yes. Rebelvolt systems are fully compatible with existing diesel generators and can operate in parallel to provide a hybrid solution. They integrate seamlessly with your current power setup to reduce fuel use and optimize reliability.

ROI depends on usage, fuel costs, and operational context. Typical deployments show substantial savings through reduced fuel consumption (up to 70 percent in hybrid use), lower maintenance costs, and minimized downtime, often achieving payback within a few years.

Yes. Rebelvolt systems include monitoring and control interfaces that can integrate with existing site management platforms or energy management systems, allowing centralized monitoring, scheduling, and performance tracking.

Switching from diesel to Rebelvolt can reduce CO₂ emissions by hundreds of kilograms per day per system, depending on load. Hybrid use with diesel generators can save up to 70 percent of fuel and related emissions.

Yes. By reducing noise, emissions, and fuel consumption, Rebelvolt systems support environmental compliance, sustainability initiatives, and corporate or governmental decarbonization targets.

Rebelvolt systems should be stored in a dry, ventilated area, ideally at moderate temperatures (0°C to 30°C), with batteries at 30–60% state of charge for long-term storage. Batteries should be recharged every three months to maintain optimal performance. Avoid exposure to extreme heat, cold, or moisture, and check battery status periodically if stored for extended periods.
