In Estonia, one diesel generator rental company turned to ROYPOW PC15KT mobile energy storage systems (ESS) to enhance its temporary power solution for an outdoor event, achieving less fuel consumption, quieter operation, and lower operating costs.
Customer Requirements
The customer required a reliable energy storage system to complement their diesel generator solutions and address the following challenges:
- High fuel consumption and maintenance costs caused by long generator runtime
- Noise issues caused by generator operation at event sites
- Limited flexibility in meeting diverse load requirements
ROYPOW Solution
ROYPOW supplied two PowerGo Series PC15KT mobile energy storage systems to work alongside the customer’s diesel generator, powering outdoor event loads such as mobile lighting, TVs, PCs, and heating equipment.
By sharing the load, the hybrid energy storage systems significantly reduce generator runtime while maximizing the load efficiency of generators, contributing to lower fuel consumption and reduced maintenance costs. While the battery units supplied power, noise levels were minimized, providing quieter energy support.
Beyond this, the ROYPOW systems deliver even more by enabling automatic generator start/stop. During transportation from the warehouse to the event site, the PC15KT ESS controlled the diesel generator via dry contacts, automatically self-charging when battery levels were low. This eliminated the need for in-service maintenance and reduced labor requirements. Throughout the outdoor event, the systems ensured continuous, uninterrupted power for all critical loads.
Solution Benefits
Compact, Portable, and Jobsite-Ready
Unlike conventional bulky and heavy commercial and industrial (C&I) energy storage systems, the ROYPOW PC15KT is compact and lightweight, allowing easy transport by pickup trucks and making it ideal for flexible rental use across diverse scenarios, including:
- Outdoor events (live concerts)
- Construction sites (charging cleaning, welding or cutting equipment)
- Farms (charging drones for irrigation)
- Ranches (powering water pumps)
- Electric vehicle (EV) charging
- Emergency backup
Rugged and Reliable
The inverters and batteries inside the ROYPOW PC15KT mobile energy storage system are specially reinforced for superior vibration resistance, minimizing the risk of system instability or damage during frequent transportation, even on rough or bumpy roads. This enhanced durability helps reduce maintenance requirements and associated costs.
High Flexibility
The ROYPOW PC15KT mobile energy storage system supports parallel operation of up to six units, delivering a total output of up to 90 kW / 198 kWh, and also allows battery-only parallel connection to flexibly match different power demands. The system can be recharged via diesel generators, solar panels, or the utility grid, enabling seamless integration into hybrid power setups and ensuring reliable energy supply across a wide range of both off-grid and on-grid rental applications.
Intelligent Management
The system supports 4G LTE remote monitoring 24/7 to manage and to optimize energy consumption. Built-in GPS function enables location monitoring, helping prevent loss of assets, ensuring equipment safety throughout the rental lifecycle.
Lower Total Costs of Ownership
Throughout its lifecycle, the system is designed to minimize costs:
- Lower upfront costs compared to standard C&I energy storage systems
- No need for costly, larger-scale diesel genset
- Lower fuel consumption, less affected by high and volatile fuel prices
- Lower maintenance and labor costs
If you are looking for a reliable, efficient, and cost-effective solution that reduces upfront investment, lowers operating costs, supports diverse rental applications, and expands your rental business, ROYPOW is your ideal partner.
