Frequently Asked Questions
DOD refers to how much a battery can be used relative to its total capacity. Higher DOD means more usable energy. This lithium battery's DOD is as high as 90%, compared to 50% of traditional lead acid batteries.
Pros of low-voltage batteries include lower cost, easy maintenance, and better compatibility. They are more affordable, require less effort to maintain, and work well with various systems.
However, there is a drawback. When the accumulative current in the system becomes too large, it can potentially lead to safety and efficiency issues.
But for residential storage systems below 20kWh, low-voltage batteries are a more balanced and economical choice.
The lithium battery is designed for longevity, offering over 20 years of reliable service with good maintenance and favorable ambient conditions.
kWh stands for kilowatt-hour, a unit of energy representing the power of one kilowatt running for one hour. The duration a 4.8kWh battery can last depends on the load it's powering. For example, if you're using appliances that total up to 480 watts, the 4.8kWh battery would last for approximately 10 hours. However, for a 960-watt load, it would last about 5 hours. The actual duration can vary based on efficiency and other factors.
- Regular Charging: Avoid complete discharges. Charge the battery regularly without letting it drop to 0%.
- Optimal Charge Levels: Maintain charge levels between 20% and 80% to reduce stress and extend battery life.
- Ambient Temperature: Store and use the battery in moderate temperatures, avoiding extremes of heat or cold.
- Proper Storage: If not in use for extended periods, store the battery at a 50-60% charge in a cool, dry place.
- Avoid Fast Charging: Unless necessary, avoid fast charging as it can increase the battery's temperature and wear it out faster.
