Frequently Asked Questions
What is the BESS 45 and what can it power?
The BESS 45 is a 45 kVA commercial battery energy storage unit available for short and long-term hire across Sydney, Greater Sydney, Brisbane, and Canberra. It can power mid- to large-scale construction-site loads, telecommunications equipment, commercial facilities, lighting systems, HVAC units, AV setups, and other mid-range commercial loads. It’s ideal for projects that require clean, quiet, emissions-free power at a meaningful scale.
How does the BESS 45 compare to the BESS 15?
The BESS 45 delivers 3x the output of the BESS 15, making it more suitable for larger, more power-intensive applications. While the BESS 15 suits small site offices, telecoms huts, and lightweight event loads, the BESS 45 is better matched to active construction sites, industrial facilities, and hybrid diesel-battery configurations. Call 1300 767 257 if you’re unsure which unit is right for your project.
Can the BESS 45 run in a hybrid setup with a diesel generator?
Yes. When it’s paired with a diesel generator in a hybrid configuration, the BESS 45 can reduce fuel consumption by up to 40%, cut maintenance requirements by up to 50%, and significantly lower CO₂ emissions across your project. The HIMOINSA HICORE system intelligently switches between power sources based on your live load profile, optimising efficiency automatically.
What is the battery life and cycle rating of the BESS 45?
The BESS 45 uses Lithium Iron Phosphate (LFP) batteries rated for 6,000 charge cycles. At one cycle per day, this equates to a useful battery lifespan of approximately 5 years.
Is the BESS 45 suitable for construction sites in Sydney and Brisbane?
Yes, the BESS 45 is a strong fit for construction site power applications across Sydney, Greater Sydney, Brisbane, and Canberra. Its zero-emission output, low-noise operation, and 300% motor-starting overload capacity suit urban or residential areas where diesel exhaust and generator noise are a concern.
How long can the BESS 45 run before it needs recharging?
Runtime depends on the load being drawn. At 100% of rated load, the BESS 45/45 configuration provides approximately 1.22 hours of autonomous discharge. At 75% load, the runtime is around 1.46 hours; at 25% load, it is approximately 2.91 hours. For continuous operation, the BESS 45 is best used in a hybrid configuration with a diesel generator or solar input, so it can recharge while supplying power.
Do you deliver and install the BESS 45?
Yes, our team delivers, installs, and commissions the BESS 45 at your site. We also provide on-site training, so your team can operate the unit safely and confidently. Remote monitoring via the HICORE app is active throughout the hire period, giving our technicians visibility of system performance at all times.
