FAQ

Common Questions From Buyers

What is the ROI for a commercial BESS installation?

Typical ROI for commercial peak shaving is 2–4 years based on demand charge reduction alone. With time-of-use arbitrage in markets like South Africa (R3.69/kWh peak vs R0.86/kWh off-peak), ROI improves to 1.5–3 years.

Do you offer remote monitoring for BESS sites?

Yes. All our BESS systems include 4G LTE connectivity and cloud EMS platform. Monitor state-of-charge, health, energy flow, alerts, and performance from a single dashboard. API available for integration.

Can these systems work completely off-grid?

Yes. Our hybrid and off-grid BESS systems support island mode — disconnecting from the grid entirely and running on solar + storage + optional diesel generator. Includes automatic transfer switch (ATS).
