Description
The design is modular, and several inverters add up to more system power. A DC/DC converter is built in, so the battery connects directly without an external matching unit. The inverter holds rated power up to +45 °C, so output does not drop in an unheated switch room in summer. Supported batteries include Storage XL,,, and Cegasa, and the approved list also covers Sunwoda, and ZYC. Battery communication runs over CAN or Modbus depending on the battery model. In off-grid mode the battery is not discharged below 6% SOC, and PV curtailment starts no later than 95%. Approved batteries require inverter firmware 3.04.xxx.R or later.
How to choose
Choose between the SI30-20 and SI50-20 by peak load and by the power to be drawn from the battery. For Storage XL the approved versions are Indoor 89 and Indoor 197 for indoor rooms and Outdoor 107 and Outdoor 197 for outdoor sites. A house or small site with loads up to 8 kW per phase is closer to the Sunny Island 6.0H / 8.0H. Grid-scale storage of several megawatts is built on the Sunny Highpower Storage at 100–180 kVA.
