Learn how to combine DEUTZ gensets with BESS in this step-by-step guide. Discover how hybrid energy systems can cut fuel use, boost efficiency, and deliver reliable off-grid power in Australia.
Across New Zealand’s farms, construction sites and remote industries, reliable power is essential. A hybrid energy system that combines DEUTZ diesel gensets with a Battery Energy Storage System (BESS) provides dependable, efficient energy while reducing fuel use and emissions.
Hybrid power is becoming increasingly popular across the country, supported by initiatives like EECA’s Solar on Farms programme, which helps Kiwi farmers adopt solar and battery storage technologies to improve efficiency and cut costs.
With New Zealand’s growing focus on renewable energy and off-grid resilience, this guide explains how to design a system that suits local conditions, from windy Canterbury to isolated sites in Northland.
Why Combine DEUTZ Gensets with a BESS?
Pairing a DEUTZ genset with a BESS creates a smart hybrid system that automatically balances renewable, battery and diesel inputs. This combination offers:
- Lower fuel consumption through intelligent load sharing
- Reduced emissions aligned with New Zealand’s Zero Carbon Act targets
- Reliable power during variable weather or renewable dips
- Automation that reduces manual oversight
Whether you’re supporting an off-grid horticulture business or a South Island worksite, a hybrid DEUTZ setup delivers efficient, sustainable power.
Step-by-Step Integration Process for Gensets with BESS
Step 1: Assess your power demand and site environment
Start by analysing daily and seasonal energy use. Also measure your peak demand (kW), total daily consumption (kWh) and critical loads such as pumps, coolers or milking systems.
At the same time, you should also review:
- Local renewables: average sun hours or wind availability
- Temperature range: important for battery performance
- Fuel logistics: refuelling access and delivery
For example, a remote dairy farm in Taranaki may rely heavily on power for irrigation and cooling at night. Storing solar energy in a DEUTZ BESS can supply this load after dark.
Step 2: Select the right DEUTZ genset
The next step is to make sure you choose a DEUTZ Power Solutions genset that meets your peak and charging requirements. When deciding, consider whether it can:
- Handle maximum power demand
- Recharge the BESS efficiently
- Provide reliable backup when renewable or grid power is low
DEUTZ gensets are built for New Zealand’s tough conditions, from coastal humidity to alpine cold.
Step 3: Choose the right BESS capacity
It is essential that you match your DEUTZ BESS to your load profile. When doing this, keep the following in mind:
- Energy capacity (kWh): how much power can be stored
- Power output (kW): how quickly it can be delivered
- System compatibility: integration with genset and renewables
For example, a North Island cropping farm might use a 120 kWh BESS with an 80 kVA genset to store solar energy and reduce diesel runtime.
Step 4: Integrating controls and smart management
Effective hybrid systems rely on intelligent control. DEUTZ controllers use algorithms that:
- Start or stop the genset automatically based on battery charge
- Keep the genset in its most efficient range (about 70–80 percent load)
- Use renewable energy first, then battery power, then diesel backup
This is incredibly useful as remote monitoring lets you track fuel use and performance in real time.
Step 5: Commissioning and testing
It’s not over once everything is installed! Following installation, DEUTZ technicians ensure the system runs smoothly through:
- Load-balancing and efficiency tests
- Communication checks between genset and BESS
- Final tuning for local site conditions
Step 6: Maintenance and optimisation
As with all engines and machinery, regular maintenance keeps performance high. DEUTZ recommends:
- Genset servicing every 250–500 hours
- Battery health checks and software updates
- Annual performance reviews
You can adjust control settings as energy demand or renewable input changes.
