Battery Pros
- Long Warranty
- Warranty is 10 years or over, which shows commitment to their product.
- 10 kWh or more of usable storage
- Typical household usage requires at least 10 kWh of power storage to be useful, this has it in the one unit.
- Cheap warranted per kWh cost
- Your in warranty cost is less than $0.30 per kWh.
- Full Depth of Discharge
- All the battery capacity is available for you to use.
Battery Cons
- Low Round Trip Efficiency
- Loosing more than 10% in power in a charge/discharge cycle. Requires more charging power than a more efficient system for the rated output. You need to take this into account when working out the true costs.
