Low-voltage energy storage systems, typically operating within a voltage range of 40-60V, are designed to provide safe and manageable energy solutions for home environments. Unlike high-voltage systems that require series configurations of smaller battery cells, low-voltage systems operate on parallel configurations, allowing larger, cost-effective battery cells with capacities of 100Ah or more. This configuration not only reduces costs but also simplifies the balance-of-system (BOS) requirements, making these systems more accessible for residential use.
Solis S6-EH3P(8-15)K inverter for low-voltage residential energy storage features a 48V battery voltage range and is designed to meet varying household demands. It integrates seamlessly with PV panels and diverse battery types, including lithium-ion and lead-acid batteries.
The system allows up to six units to be connected in parallel, achieving an expanded capacity of up to 90 kW. This adaptability is particularly beneficial in residential settings, where energy requirements can increase over time as households incorporate more power-hungry devices or expand living spaces.
The system is generator-compatible, allowing automatic switching between battery and diesel generator during power outages ensures uninterrupted energy supply. Smart load management feature prioritizes essential appliances, optimizing energy use and enabling peace of mind for households in off-grid scenarios. The system provides dedicated outputs for critical and non-critical loads, ensuring that essential devices remain powered even during extended outages.
With a 200% overload capability, the S6-EH3P(8-15)K can handle the power demands of high-consumption appliances, such as air conditioners and refrigerators, without compromising performance.
Offering 4ms switching speed during power cuts, this inverter supports sensitive devices.
Technical advantages of low-voltage systems
- Cost-effective maintenance and scalability: Parallel battery configurations allow for individual battery module replacement without affecting the system, making it easier and more affordable to maintain. Low-voltage systems also support flexible expansion by adding parallel modules, which can increase system capacity without requiring voltage adjustments.
- Enhanced safety: The lower voltage of these systems translates to reduced operational risk, making them safer for household environments. Users can perform maintenance tasks without the need for extensive technical expertise or high safety precautions, a significant advantage over high-voltage systems.
- Efficient power management for residential use: Although high-voltage systems are more efficient for long-distance transmission, low-voltage systems perform effectively within residential applications due to shorter transmission distances and optimized design to mitigate power loss from high current.
