Modular Capacity for Reduced Inventory Risk
Managing multiple energy demands across different residential properties often leads to heavy inventory burdens for wholesale distributors. Our system utilizes a highly adaptable vertical stacking structure featuring the standardized BTS 5K lithium iron phosphate battery module.
Each storage block delivers an energy capacity of 5.12 kWh. Regional wholesalers only need to stock one standard battery module to effortlessly tailor storage configurations from 5.12 kWh, 10.24 kWh, 15.36 kWh, 20.48 kWh, 25.6 kWh, up to 30.72 kWh on-site, perfectly fitting diverse household energy profiles.
FAQ
Q: How does the system handle strict regional grid compliance regarding power quality and injection limits?
A: The integrated ESI hybrid inverter series features an advanced grid-control processor that actively manages power quality. It supports dynamic power factor adjustments ranging from `0.8 lagging` to `0.8 leading`, enabling active reactive power compensation.
Q: What is the efficiency curve and internal consumption profile of the all-in-one system during standby/night mode?
A: The system achieves a peak inverter efficiency of 97.6% and a European efficiency of 97.0%, while the round-trip efficiency (RTE) of the battery module sits above 95%.
Q: How does your system manage mismatched module states of charge (SoC)?
A: The BTS 5K battery bank features built-in module-level active balancing alongside integrated DC/DC converters in each unit. This means that our system allows modules with slightly different states of charge or aging profiles to operate independently at their optimal thresholds, preventing system-level derating.
Q: Can this all-in-one ESS be installed outdoors in regions prone to heavy rain, dust storms, or high humidity?
A: Yes, the entire structural enclosure is engineered with a strict `IP65` ingress protection rating, making it completely dust-tight and resistant to heavy rainwater jets.
Q: If an end-user has an issue in the field, what remote diagnostics and firmware update protocols are available to our engineering team?**
A: The system provides full cloud connectivity through our professional Web and App portals. It comes standard with integrated `RS485, CAN, and Wi-Fi` communication channels, with optional expansions for `Ethernet and 4G` cellular modules.
