Inveters

Grid 300 and Grid 500

The inverter series comprises the Grid 300 and Grid 500 inverters, with rated outputs of 300 W and 500 W, respectively.

Grid 300 and Grid 500 are built in a modular manner and are simple to install. With distribution over three phases, the system can at any time be expanded as desired, and thus flexibly adapts to your solar power system. Grid 300 and Grid 500 have an independent MPP tracker and achieve a very high efficiency of up to 95.8%.

The DualString product range consists of masters and slaves. Like the slaves, the master includes an inverter, but also provides additional functions: four-line display, data logger for storing the yield values, country-specific grid monitoring of the alternating current output, and optional use of an interface card.

Flexible system design

The Grid 2000+ uses the DualString concept. This means that every inverter (master or slave) has two inputs, with each input having its own MPP tracker. One module string can be connected to each input. If required, the inputs can also be connected in parallel.

The advantage of such a system is the low sensitivity to negative influences such as partial shadowing, functional faults, or the dropout of a string. The use of several decentralised master-slave combinations reduces the cost of DC cabling, and minimises electrical losses.

Inverter topology

The new “Coolcept” inverter topology, with an innovative circuit design that achieves highest efficiency, has now been integrated into the Grid 3000 and Grid 3600.

The "Coolcept" inverter topology is based on a single-stage transformerless switching concept that uses proven standard components to implement symmetric step-down converters with downstream pole-reversing circuits.

Highest efficiency with longer service life

The high efficiency results in a peak efficiency of 98.6% and a European efficiency of 98.2% resp. 98.1%, which results in less lost power that must be dissipated into the environment. This improves your yields.

The efficiencies of the Grid 3000 and Grid 3600 are only very slightly dependent on the module input voltage. This allows the number and type of modules to be freely selected without resulting in a yield loss.

The advantage of three-phase feeding is that the produced solar capacity is always symmetrically distributed on all three power conductors to the public power grid. This is the case across the whole output range offered by these inverters. When designing a system, the laborious avoidance of an asymmetry of more than 4.6 kW through the appropriate selection of separate inverters is thus dispensed with. Symmetrical feeding is greatly in the interests of energy supply companies. Lengthy discussions with such companies are therefore a thing of the past.
