redT flow machines separate power (kW) from energy (kWh), making the system easily scalable.

The product range is based on the redT 5kW stack module. The stack size determines the power, whilst the liquid electrolyte volume determines the energy capacity. By using the 5kW stack as a ‘building block’, you can combine systems up to MW scale.

For example, our popular 45-225 machine has 9 stacks. It stores 225kWh of energy and continuously discharges 45kW of rated power for 5 hours.

The machines below can be combined together to achieve multiple unit systems which meet precise requirements. Contact us so we can help you select the correct system configuration.

*Continuous discharge duration at rated power. Duration is proportional to power requirements i.e. if discharging at 50% rated power, duration is doubled.


Connect multiple units together to create system sizes up to 10MW. Examples below.
