Newton Victron Sump Pump Battery Backup Kit (60Ah)

What does a battery back-up system do for a sump pump?

It keeps the pump running during a power cut by converting stored battery energy into usable mains electricity.

How long will the 60Ah battery last?

Run time depends on pump size, usage and inflow rate. Additional batteries can be added to increase operating duration.

Can I add more batteries to this system?

Yes, compatible 12V batteries can be connected in parallel to increase available capacity and extend run time.

Does this system meet PCA guidance for battery back-up?

The Property Care Association (PCA) Best Practice Guidance for Groundwater Pumping Stations recommends that battery back-up systems should be capable of operating a pump for up to 24 hours, based on a typical cycling rate of up to 3 starts per hour.

Testing data for a 60Ah battery indicates it can deliver approximately 100 pump activations and up to 6600 litres of pumped water, with a run time of around 25 hours under typical operating conditions.

This means the system is capable of meeting PCA guidance in many installations, provided it is correctly specified to match the pump performance, head height and expected water ingress.

For projects with higher water demand or risk profiles, additional battery capacity may be required.

When would this system not be suitable?

This battery back-up kit is designed to maintain sump pump operation during temporary power outages. However, it may not be suitable in certain scenarios where system demand exceeds available battery capacity.

Examples include:

• Very high or continuous water ingress – where pumping demand exceeds the capacity of the battery and pump combination.
• Extended power outages without additional batteries installed to increase run time.
• Non-compatible pump systems or installations without appropriate electrical provision.
• Situations requiring full flood resilience without reliance on power – where additional or alternative waterproofing measures may be required.

Correct system design is essential to ensure the battery capacity matches the expected water ingress and pumping requirements.

How long does a battery backup sump pump last?

The lifespan of a battery back-up system depends on both the inverter components and the battery itself.

The Victron inverter/charger is designed for long-term use with high-quality components and typically provides many years of reliable operation when correctly installed.

The 60Ah VRLA battery has a design life of over 10 years under normal conditions, although actual lifespan will depend on usage, discharge frequency and environmental conditions.

Regular inspection and maintenance are recommended to ensure continued performance, and batteries should be replaced periodically as part of a planned maintenance strategy.

Is the Victron suitable for foul sump pump systems?

The Victron inverter system is suitable for use with many sump pump installations, including foul water systems, provided the pump is compatible and correctly specified.

The inverter delivers stable 230V AC power with true sine wave output, making it appropriate for pumps that require consistent electrical performance.

However, foul water systems often have higher flow rates, increased solids handling requirements and may place greater demand on the pump and power supply.

For this reason, it is important that the battery capacity, inverter size and pump specification are matched to the specific system requirements to ensure reliable operation.
