Frequently Asked Questions
We recommend solar panels with total power exceeding 4000W for optimal daily charging. For example, with 6+ hours of average daily sunshine, a 4-5kW solar array will fully charge the 20kWh battery pack efficiently.
Runtime depends on connected loads. For example, the 20.48kWh capacity can power a 2kW load for approximately 10 hours, a 5kW load for 4 hours, or a 10kW load for 2 hours. Actual runtime may vary based on discharge rate and efficiency.
Yes, multiple units can be connected in parallel to increase total capacity. The system supports parallel configuration through standard communication protocols. Contact our engineers for proper parallel connection guidance.
The mobile APP control module is optional and can be added to your order. The APP provides remote monitoring, system diagnostics, and control features accessible from iOS and Android devices.
The battery pack includes a 10-year warranty with performance guarantee. The battery is warranted to retain at least 80% of its rated capacity after 6000 cycles or 10 years of normal use, whichever comes first.
