Native 220/380V and 230/400V Three-Phase Output
Support for both 220/380Vac and 230/400Vac lets the same 50–60kW platform match common European low-voltage three-phase systems. IESP500SH3, IESP550SH3 and IESP600SH3 cover 50kW, 55kW and 60kW rated output while remaining on the same platform.
98.1% Maximum Efficiency
A 98.1% maximum-efficiency rating reduces inverter-stage conversion loss and provides a clear performance benchmark for long-running storage systems. The IESP 50–60kW EU datasheet lists 98.1% maximum efficiency, 97.6% European efficiency and MPPT tracking efficiency above 99%.
Four MPPTs for Large Commercial PV Layouts
Four independent MPPTs make it easier to divide a large 380/400V C&I solar array into separate electrical operating points instead of forcing all strings onto the same tracker. The IESP EU series provides four MPPT trackers, each supporting up to 40A PV input current and 60A short-circuit current, with a 150–850V MPPT range and 1000V maximum PV voltage.
Dual 150–820V Lithium Battery Inputs
IESP 50–60kW EU uses a high-voltage battery bus to reduce DC current at the same power level, easing current demand on cabling and protection in higher-power storage systems. The EU IESP uses a 150–820Vdc high-voltage lithium-ion battery platform with two battery inputs and up to 160A total charge/discharge current arranged as 80A + 80A.
Maintain Backup Continuity with Generator Support and 10ms Transfer
Diesel-generator integration gives the IESP 50–60kW EU another energy source during extended grid outages, while a typical 10ms transfer reduces interruption when utility power is lost. A 200A maximum bypass overload path is also available when accepted AC power is supplying loads, but bypass current remains separate from inverter output.
Scale C&I Storage to Nine Inverters
Parallel operation lets a C&I storage project add inverter capacity as facility demand grows instead of oversizing the first installation. The IESP 50–60kW EU supports 1–9 units in parallel, providing a defined expansion path for larger 380/400V commercial and industrial systems.
