PDTSTS125-225kWh-400-A on/off-grid solar-storage system, 20ms seamless switching, supporting up to 200kW PV input, tailored for high energy consumption and high reliability commercial & industrial scenarios
⚡ Energy costs are rising, grid fluctuations frequently affect production, rooftop photovoltaics cannot be fully consumed... Are these problems troubling your business?
Under the "dual carbon" wave, commercial and industrial users face both pressure to save energy and reduce costs, and need to ensure power reliability and continuity. The traditional single grid power supply mode can no longer meet complex and changing energy needs - high electricity costs, uncontrolled power outage risks, low PV self-consumption rates, high cost and pollution from diesel generation... How to break through?
PDT's PDTSTS125-225kWh-400-A on/off-grid solar-storage system, with 125kW power/225kWh capacity as the core, integrates photovoltaics, energy storage and intelligent control, tailored for commercial and industrial scenarios with high energy consumption and high reliability requirements. Whether it's factories, office buildings or microgrids, it can precisely solve your energy pain points.
🎯 We Understand the Pain Points of These Scenarios!
🏭 Factories & Mines: Contradiction Between Production Rhythm and Energy Costs
- Pain points: Large equipment start-stop impacts cause high demand charges; production lines run 24 hours, peak-valley price differences bring huge waste; grid fluctuations or power outages may cause entire production lines to shut down
- Needs: Need to smooth loads and peak shave while ensuring critical equipment doesn't lose power during grid anomalies
🏨 Hotels & Office Buildings: Dual Test of Reliability and Green Image
- Pain points: Elevators, fire protection, lighting and other critical loads have extremely high requirements for power continuity; fluctuating occupancy rates make energy consumption forecasting difficult; rooftop PV generation doesn't match building energy consumption patterns
- Needs: Need intelligent energy flow regulation to maximize PV self-consumption while having islanding capability to ensure core facility power supply
🌄 Microgrids/Remote Areas: High Renewable Energy Ratio and Power Islands
- Pain points: Large PV fluctuations, reliance on diesel generators for supplementation, high fuel consumption and maintenance costs; insufficient system reliability, unable to operate off-grid for extended periods
- Needs: Need deep integration of solar-storage-diesel, achieving all-weather stable power supply, significantly reducing diesel dependence
💡 One System, Precisely Solving Problems!
The PDTSTS125-225kWh-400-A on/off-grid solar-storage system is the "energy butler" tailored for the above scenarios. How does it solve user pain points?
💰 Peak Shaving, Reducing Electricity Costs
The system has built-in intelligent EMS that can be configured with price signals and real-time load curve sensing, charging during off-peak periods and discharging during peak periods, effectively reducing demand charges and overall electricity costs. For factories and mines, it can also dynamically adjust charge/discharge strategies based on production rhythm, avoiding equipment start-stop impacts.
⚡ 20ms Seamless Switching, Ensuring Critical Power Supply
When grid anomalies occur, the system can automatically switch to off-grid mode within 20ms, providing uninterrupted power for precision equipment, keeping your business always powered.
☀️ Efficient PV Self-consumption, Increasing Green Power Ratio
Supports up to 200kW PV input with 2 independent MPPT trackers, prioritizing PV power for loads or battery charging, with excess power able to be fed to the grid, effectively improving PV self-consumption rates.
🔋 Diesel Coordination, Reducing Fuel Consumption
In microgrid scenarios, the system efficiently integrates solar, storage, and diesel through the DC bus, with intelligent diesel generators only starting during extreme cloudy/rainy periods or sudden load increases, making clean energy truly the main power source.
