What cells does Turno BESS use?

Grade A cells from EV battery packs, given a second life. Every cell is tested and graded by Turno's battery intelligence system before it goes into a pack.

What is the cell chemistry?

The cells are lithium-ion cells.

How does it talk to the inverter?

Over CAN, RS485 or RS232, with protocols pre-programmed to match leading hybrid and off-grid inverters. If an inverter doesn't support a compatible protocol, the battery still runs without communication in standard 48V mode.

What is the depth of discharge?

Usable depth of discharge is 90%, within an operating range of 10% to 100%.

What does the BMS do?

Cell-level balance monitoring with multilayer hardware security lockout. It also powers real-time status monitoring in the Turno app and remote firmware upgrades.

Can I mix 5 kWh and 12 kWh units?

Stack each model with itself: 5 kWh with 5 kWh, 12 kWh with 12 kWh. Up to 16 units can run in parallel.

What does the 10-year warranty cover?

Every Turno BESS carries a 10-year warranty for usage under standard conditions, as set out in the product warranty catalogue. We'll share the catalogue along with your partner pricing.
