1.EMS: Remote monitoring of system performance and power usage.
2.Peak shaving: Charge during low-rate hours, discharge during peak demand.

Haihan's EMS (Energy Management System) provides intelligent storage solutions, enabling real-time monitoring, data analytics, and automated power scheduling to maximize system efficiency.

With EMS, peak shaving strategies can be easily implemented—storing electricity during low-rate hours and discharging during peak demand to cut electricity costs and reduce grid load.

Haihan's intelligent Operation Maintenance not only ensures technical reliability but also delivers tailored energy management for both residential and commercial users.

1.Demand Response: Support grid stability during power shortages.
2.Energy Trading: Sell surplus energy back to the grid.

In partnership with licensed aggregators, Haihan acts as a bridge between energy storage system owners and power utilities. Our system can be dispatched in real-time to help alleviate grid shortages.

This aggregation model also enables participation in energy trading, where stored energy can be used to support both internal loads and grid demand—generating potential incentives and enhancing overall energy efficiency.

Our goal is to build a smarter, more efficient energy ecosystem—one that reduces waste, increases self-sufficiency, and accelerates renewable energy adoption.
