Context

 

A residential complex with frequent grid outages, dependent on costly, polluting diesel generators. The site needed continuous power, lower bills, and zero diesel.

 

What MMS does

​

• Operates a 50 kWp PV + 200 kWh BESS microgrid

• Seamless transition to islanded operation during grid loss

• Dynamic battery dispatch for resilience and tariff optimisation

• Prioritisation of essential loads during scarcity

​

Outcomes

​

• Diesel generator use eliminated

• >20% reduction in resident energy costs

• Continuous power during grid outages

• Demonstrated net-zero backup energy system

 

Why it matters

 

​Residential microgrids are usually written off as too small to be worth the intelligence. Sanepa shows the opposite: with the right software, even a modest PV-plus-battery install can replace diesel completely, cut bills, and keep the lights on through grid failures.
