Frequently asked questions

How does Harmony Boost work?

Harmony Boost combines three power sources: a 60kW AC grid connection, solar energy from PV arrays with Maximum Power Point Tracking (MPPT), and an advanced battery energy storage system. The battery stores energy from the grid and solar panels, then releases it to provide high-power charging—up to 400kW total—when EVs need it, ensuring seamless operation without overloading the grid.

How many EVs can charge at once with Harmony Boost?

Harmony Boost supports up to six charge points operating simultaneously, with a total maximum output of 400kW. The power is dynamically shared among the connected vehicles, so each charger’s output depends on how many EVs are plugged in and their charging needs.

What role does solar energy play in the system?

The PV solar arrays, equipped with MPPT technology, generate renewable energy to supplement the grid and charge the system’s battery. This reduces reliance on fossil fuel-based grid power, lowers operating costs, and ensures charging availability even during peak demand or in off-grid scenarios, making it a greener solution.

How fast can Harmony Boost charge an EV?

Charging speed depends on the EV’s capabilities and how many vehicles are charging at once. With a maximum output of 400kW across six points, a single vehicle could potentially access up to 400kW for ultra-rapid charging, while six vehicles might average around 66kW each. Actual speeds vary based on the EV’s battery and charger compatibility.

What kind of maintenance does Harmony Boost require?

Harmony Boost is designed for durability and low maintenance. Regular checks on the battery, solar panels, and charging hardware ensure optimal performance. The system’s smart power management software also monitors operations in real-time, reducing wear and tear. Specific maintenance schedules depend on installation conditions and usage.

Can Harmony Boost be customized or scaled for different locations?

Yes, Harmony Boost is modular and adaptable. The size of the battery, solar arrays, and number of charge points can be tailored to meet the needs of specific sites - whether it’s a busy urban hub or a remote highway stop - making it a versatile solution for starting small and future expansion of your EV infrastructure.
