Buyer questions
Confirm compatibility before ordering.
How much backup time can a 16.08 kWh battery provide?
Runtime depends on usable energy, connected load, inverter efficiency, reserve settings, temperature and battery condition. Provide the load list and backup target for a project calculation.
Which inverter can communicate with this battery?
Compatibility depends on voltage limits, current, BMS protocol and firmware. Send the exact inverter model so the electrical and CAN or RS485 communication requirements can be confirmed.
Can up to 15 batteries always be connected in parallel?
The published product data states support for up to 15 units. The final quantity, protection, cable sizing, addressing and commissioning procedure require written model-level confirmation.
Is 16.076 kWh the 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
