12kW 64kWh Rack-Mounted Commercial Energy Storage System with Dual MPPT
This 12kW 64kWh commercial energy storage system combines pure sine wave output, a rack-mounted battery architecture, dual MPPT solar charging, dual AC output and multi-interface monitoring in one coordinated solution.
The battery system provides 64kWh of rated energy and approximately 57.6kWh of usable storage at 90% depth of discharge. This larger energy reserve is designed for commercial sites that need to maintain selected business loads for longer periods rather than operating every circuit during an outage.
Suitable applications may include small offices, retail stores, clinics, communication rooms, farm facilities, service stations and other commercial properties with clearly defined priority loads. The final configuration should be based on actual consumption, startup demand and required backup duration.
Daytime Solar Utilization
Photovoltaic generation can support compatible business loads while additional solar energy charges the battery.
Essential Load Backup
Lighting, communication equipment, security systems, refrigeration and selected office devices can be assigned to priority circuits.
Dual AC Load Distribution
Dual AC outputs help separate critical equipment from flexible or higher-consumption loads during utility interruptions.
Extended Outage Recovery
Compatible utility input or a properly sized generator can provide additional battery charging when solar production is insufficient.
The 12kW inverter rating determines the maximum combined continuous output. Commercial equipment with compressors, pumps or motors must also be checked for startup current and simultaneous operation before the final load schedule is approved.
The dual MPPT solar charger supports up to 15kW of photovoltaic input. Two tracking channels can be used for suitable solar strings installed on separate roof areas or orientations, provided each string remains within the specified voltage and current limits.
The 57.6kWh usable battery reserve determines expected operating duration. Actual runtime depends on average load, inverter efficiency, battery reserve settings, temperature and whether solar or generator charging remains available.
A commercial load assessment should separate equipment that must remain operational from loads that can be delayed, limited or disconnected during an extended outage.
| Commercial AC Output | 12kW / 220, 230 or 240Vac / L + N + PE / PF 1.0 |
| AC Input Range | 90–280Vac Normal Mode / 170–280Vac UPS Mode |
| Transfer and Waveform | 10ms APP / UPS Mode; 20ms Generator Mode / Pure Sine Wave |
| Solar Charging Platform | Dual MPPT / Up to 15kW PV Input |
| PV Voltage Limits | 60–450Vdc Operating Range / 500Vdc Maximum Open-Circuit Voltage |
| Charging Current Limits | 160A PV / 160A AC / 160A Combined |
| Battery Electrical Platform | 51.2Vdc Nominal / 40.0–58.4Vdc / 400A Charge and Discharge |
| Monitoring and Communication | LCD / WiFi / RS485 / RS232 / USB / Dry Contact |
| Installation and Module Data | IP21 / -10°C to 50°C; Inverter: 745 × 440 × 176mm / 30kg; Battery Module: 745 × 440 × 240mm / 122kg |
The system supports compatible utility charging, solar self-consumption and commercial backup operation. This page does not claim electricity selling or power export to the grid.
It can be considered for small offices, shops, clinics, communication facilities and other sites with a clearly defined group of essential loads.
No. Backup time depends on the average active load. Higher consumption reduces runtime, while daytime solar charging may extend operation.
Critical equipment should be assigned to the priority output, while non-essential or high-consumption equipment should be managed separately.
Yes, when the generator provides compatible voltage, frequency and sufficient capacity for the selected charging current and active loads.
Dual MPPT can support suitable separate photovoltaic strings when each channel follows the specified power, voltage and current limits.
This 12kW 64kWh commercial energy storage system is suitable for distributors, solar installers, EPC contractors and project developers requiring long-duration battery storage for selected business loads.
