Buyer questions
Confirm compatibility before ordering.
How long can a 32.15 kWh battery support a project?
Runtime depends on usable battery energy, simultaneous load, inverter efficiency, reserve settings, temperature and battery condition. A load profile is required for a credible calculation.
Can the battery continuously deliver 300 A?
The published data lists 300 A as the maximum charge and discharge current. Continuous operating limits, cable sizing, protection and inverter power must be confirmed from the final technical documentation.
Which inverter is compatible with KT51.2V-628AH?
Compatibility depends on voltage, current, CAN or RS485 protocol, firmware and protection requirements. Send the exact inverter model for confirmation before ordering.
Is 32.154 kWh guaranteed usable energy?
No. It is the published rated energy. Usable delivered energy depends on operating limits, depth of discharge, conversion losses, settings and site conditions.
FACTORY-DIRECT EXPORT
