High yields • Excellent specific price • Full nominal power up to 50 °C • 10 % additional power in continuous operation at ambient temperatures up to 25 °C • Efficiency of more than 98 percent • Integrated DC main distribution for direct connection of the String-Monitors • Flexible plant design due to input voltage up to 1000 V Reliable • Connection of up to two external DC main distributors for diverse system configuration • Comprehensive grid management functions • Perfect monitoring of all PV strings in the field Sunny Central 400HE / 500HE / 630HE Proven high performance High flexibility in plant design and minimal systems costs with even more power: the proven High Efficiency series for direct connection to the medium-voltage transformer has once again been improved and is already equipped with the intelligent power management of the succeeding generation. This means that maximum power in continuous operation has been increased by ten percent compared to the nominal power for as long as the ambient temperature does not exceed 25 °C. At the same time, the devices offer comprehensive grid management functions – including immediate reconnection after a grid voltage drop.

Remote controlled power reduction in case of grid overload In order to avoid short-term grid overload, the grid operator presets a nominal active power value which the inverter will implement within 60 seconds. The nominal value is transmitted to the inverters via a ripple control receiver in combination with the SMA Power Reducer Box. Typical limit values are 100, 60, 30 or 0 per cent of the nominal power. Frequency-dependent control of active power As of a grid frequency of 50.2 Hz, the inverter automatically reduces the fed-in of active power according to a definable characteristic curve...
