ELS Working Modes
The ELS hybrid inverter caters to various scenarios, offering multiple working modes such as self-consumption, time-of-use optimization, and peak shaving. It adapts easily to different residential energy demands. This ensures reliable, sustainable energy solutions with smooth performance. Below are detailed applications and their recommended use cases:
1. Self-Consumption Mode
In this mode, the ELS Series prioritizes the utilization of solar energy generated by the PV system during the day. Excess energy charges the batteries, and any remaining power is exported to the grid.
Daytime: When solar energy is sufficient, it powers the load directly, with surplus energy stored in batteries or fed into the grid.
Nighttime: The inverter supplies power from the batteries. If battery power is insufficient, it switches seamlessly to the grid to ensure uninterrupted power.
Recommended: Users looking to reduce reliance on the grid and maximize self-consumption of solar energy.
2. Economic Mode
This mode allows users to optimize electricity costs by charging batteries during off-peak hours (when electricity prices are low) and discharging during peak hours (when electricity prices are high).
Seasonal Flexibility: Tailor the charging and discharging schedule based on summer and winter energy demands.
Daily Adaptability: Adjust for weekdays versus weekends to align with household energy consumption patterns.
Recommended: Areas with significant differences in electricity prices between peak and off-peak hours.
3. Time-of-Use Mode
The system operates according to predefined charging and discharging schedules based on user-defined time periods. Users can set charging during low-demand hours and discharging during high-demand hours, ensuring optimal use of stored energy.
Recommended: Users with consistent and predictable energy usage patterns who aim to reduce electricity costs.
4. Peak Shaving Mode
This mode minimizes grid dependency during peak electricity demand by limiting grid power usage and supplementing the load with PV and battery energy. During off-peak hours, the grid charges the battery for future use.
Peak Hours: Reduces electricity drawn from the grid, helping lower utility bills.
Off-Peak Hours: Charges the battery and powers loads simultaneously, ensuring maximum energy storage.
Recommended: Households with high electricity consumption during peak hours.
5. Emergency Power Supply Mode
When the grid power is interrupted, the ELS Series prioritizes powering loads using solar energy. If PV generation is insufficient, it switches to battery power, and, as a last resort, the diesel generator can take over to ensure continuous power supply.
Recommended: Areas with frequent grid instability or power outages.
