Scale as you Grow
Think of the MAX 300 as a flexible building block, allowing capacity and power to be increased over time by connecting several systems in parallel. This lowers upfront costs and improves overall returns. Equally these blocks can be easily removed, with systems reallocated to new premises wherever you have constraints or need more power.

Self-charging Hybrid
The MAX can automatically control a remote power source, such as a diesel genset, optimising efficiency and generating significant savings in diesel and maintenance, while also reducing emissions and noise impact. You can control the generator with our Smart Scheduler, and limit the current draw from the generator to avoid unwanted trip resets

Transport without barriers
The MAX 300 is classified under UN3536, meaning it is subject to minimal ADR regulation. Allye monitors the batteries in transit using the original automotive OEM protocols, ensuring safe and intelligent oversight throughout transportation, as if the batteries were still in the vehicle. We are actively engaged with regulatory bodies to expand exemptions specific to innovative systems like ours.
