These extremely scalable modular inverter systems, based on 55kW conversion modules, increase usable power and improve availability. The reduction of performance in any individual inverter will not impact the energy-harvesting capabilities of other modules. The product is available with and without isolation transformer. Industry-leading power conversion efficiencies of up to 98% (-TL), combined with high-speed Maximum Power Point Tracking (MPPT) channels, optimize energy harvesting across a wide array of operating conditions. Inverter systems are delivered pre-configured and pre-tested in rugged enclosures, significantly reducing on-site wiring and testing. In case of ungrounded application the unit can be configured as single or multiple MPPT (with exception of PVI-Central-50 & PVI-55.0/-TL).
