Many all-in-one ESS cabinets force a trade-off between simplicity and flexibility. The AirPal ECO-E101WX avoids that by combining PV integration, battery storage, intelligent control, and modular expansion in a single platform — so a project can grow with changing energy demand instead of requiring a full system redesign.
Supports a 1P charge/discharge rate for rapid energy delivery, helping the system respond quickly to sudden load changes.
Supports DC-DC modular expansion, making it straightforward to add PV capacity as a project's solar generation grows.
An optional hybrid inverter enables seamless coordination between solar generation and battery storage without extra integration equipment.
Combines battery storage, PCS, HVAC, fire protection, and intelligent control in a single outdoor cabinet — cutting installation complexity and onsite engineering time.
Supports self-consumption, peak shaving, and backup power modes, so energy usage strategy can be tuned to what actually saves the most on each site's utility bill.
An IP55-rated enclosure and compact footprint make the ECO-E101WX easy to fit into space-constrained commercial and industrial sites.

Everything You Need to Know About the AirPal ECO-E101WX All-in-one Energy Storage Cabinet
The AirPal ECO-E101WX is built for commercial and industrial (C&I) energy storage applications — factories, office buildings, shopping centers, hotels, hospitals, and industrial parks that need to cut energy costs, add backup power, or integrate renewable energy without a large-scale custom system.
It supports self-consumption, peak shaving, and backup power strategies, helping facilities maximize solar utilization, lower electricity costs during peak-tariff periods, and keep critical loads running during grid outages.
Yes. It supports DC-DC modular expansion for PV access and can be paired with an optional hybrid inverter, enabling straightforward integration between solar generation and battery storage.
The all-in-one cabinet integrates the LiFePO₄ battery system, PCS (inverter), HVAC, high-voltage box, fire suppression system (FSS), a local control box (BCQ), and intelligent monitoring — reducing the amount of separate equipment an installer needs to source, wire, and commission on site.
The system uses 120 Ah lithium iron phosphate (LiFePO₄) cells rated for 5,500+ cycles, chosen for high thermal stability and dependable long-term performance in demanding C&I applications.
Yes. It carries an IP55-rated enclosure, C4 anti-corrosion protection (C5 optional), intelligent air cooling, and an operating temperature range of -25°C to 55°C, covering most outdoor deployment conditions.
The cabinet supports Modbus TCP/IP communication and digital monitoring, so system status, operating data, and alarms can be tracked through a compatible energy management platform from anywhere.
