BESS Operation and Maintenance: How to prolong your Battery Energy Storage System (BESS)

Prolonging the life of your Battery Energy Storage System (BESS) will help optimise performance, reduce deterioration of the system and provide significant cost savings.

So what do you need to do to prolong battery life? Here are some top tips:

Regular inspections and maintenance

Regular inspections and maintenance need to be top priority if you want to ensure everything is running as smoothly and efficiently as possible.

Manufacturers’ recommendations should always be adhered to and any issues identified must be dealt with immediately to reduce the possibility of more time consuming and costly fixes.

Regular maintenance can be as simple as a visual inspection of parts, ensuring everything is clean, well connected, free of debris or moisture, and that nothing is damaged.

Correct size

Having the correct size BESS for your particular application is also important for ensuring efficiency of operation. Anything too large or too small will only result in inefficient operation and accelerate the degradation of the battery life. The DEUTZ Australia Technical Support Team and our authorised dealers can assist you in selecting the appropriate size for your BESS. Whether it involves setting up sufficient solar panels, choosing the right size for your battery storage system or selecting a compatible back up DEUTZ diesel generator, we’ve got you covered.

Climate control

Climate control is vital to maintaining optimum battery health. The specific type of battery employed in your situation will require its own specific temperature control, so the air conditioning system must always be functioning effectively. DEUTZ Australia’s BESS are designed specifically to suit our region’s weather conditions and unique environment.

Battery storage and management

Batteries should also be stored in a dry place to avoid corrosion, so ensure any protective casing is free of leaks, rust or holes.

The battery management system should also be overseen to ensure the generation and distribution of power is balanced and efficient. Optimal charging and discharging of the batteries are the aim, so voltage and current limits should be regularly inspected.

You can prolong the life of the battery by limiting the depth of discharge. When discharged almost to their maximum, strain is placed on the battery, minimising its lifespan which is why shorter discharges are preferable.

Likewise, when a battery stores energy for long periods without being drawn upon, it will begin to degrade. Manufacturers have guidelines around lengthy storage of batteries which should be followed. If you need to change or upgrade your battery storage system, our modular battery storage design allows for easy swapping capacity upgrades.

Performance monitoring

Performance monitoring on a regular basis is also another way to maintain the life of your BESS and should include checks on efficiency, capacity and internal resistance, which, if not functioning at desired levels, can be adjusted in a timely fashion.

Finally, it is important to always follow any manufacturers’ guidelines, inspect regularly, attend to maintenance issues promptly and evaluate the efficacy of monitoring systems. DEUTZ recommends having your system inspected and maintained regularly by a qualified technician in order to enjoy maximum efficiency from your BESS and prolong its life.
