Overview
The Livoltek HP3 40–60kW S1 series redefines large-scale hybrid energy storage with a three-phase inverter architecture built for maximum flexibility and scalability. Featuring five independent MPPT trackers supporting up to 45A PV input current, this inverter pairs seamlessly with high-power solar panels and delivers up to 200% PV oversizing for maximum self-consumption and reduced grid dependence.
Efficiency
A <10ms seamless on-grid to off-grid switchover provides uninterrupted backup power for critical loads, while 120% overload capability for 10 seconds in off-grid mode ensures reliable start-up of heavy inductive loads such as pumps and compressors. The inverter supports 100% three-phase unbalanced output, making it ideal for real-world commercial environments with asymmetric load profiles.
Capacity & Performance
Up to 10 units can operate in parallel for both grid-tied and off-grid scenarios, scaling total system capacity to 600kW. Dual independent battery inputs allow flexible configuration with different battery banks, while diesel generator compatibility enables multi-energy integration for sites with unreliable grid access. Built-in intelligent EMS with 7×24-hour scheduling optimises energy flows across solar, battery, grid, and generator sources. An LCD display provides an intuitive local interface, complemented by remote settings and firmware upgrades via the Livoltek cloud platform.
