Averting potential system-wide failure:

Detecting manufacturer defects in new batteries at a Nigerian bank

Man Using Bank Machine


A Nigerian bank, having faced premature battery failures in the past, sought confidence in their new off-grid system's reliability. With a recent investment in a 6-month-old battery bank, they aimed to maximize its lifespan and ensure uninterrupted power during non-operational hours.


Install's monitoring system to track and enhance the battery bank's performance, safeguarding the bank's substantial investment and ensuring reliable backup power.

Methodology integrated split-tap monitors across the 24 x 2V 1000Ah battery bank within two hours – there was 1 monitor for every 3 batteries. Leveraging the bank's operational patterns,’s monitoring focused on ensuring consistent power from 6 pm to 7 am.


The system detected an alarming overdischarge event due to a non-operational generator. Analysis pinpointed a battery with a voltage of 0.83vpc, indicating that one of the 3 batteries with a split-tap monitor had a vpc of 0.00. Leaving this unattended signalled a potential system-wide failure. Further scrutiny revealed a manufacturer defect—a micro-short in one of the 6-month-old batteries.



Prompt alerts enabled swift action: the faulty battery was replaced under warranty, preventing a catastrophic system-wide failure. This intervention not only stabilized the system but also fortified the bank's confidence, saving an estimated $10,000 in premature system replacements.


Conclusion's proactive monitoring unveiled critical vulnerabilities, enabling timely interventions that safeguarded the bank's investment. For a mere 5% of the system's cost, the solution brought confidence to the bank on the system’s value and encouraged them to expand the use of the system across more sites, allowing for centralized site management.

Explore the insights


The generator doesn’t start, causing an over-discharge of the battery bank.


Minimum reported voltage was at 0.83vpc.


During the over-discharge event the discharge current went to 142amps, almost 3 times higher than normal.
