Solis has released a new series of hybrid inverters in five different power versions, ranging from 3 kW to 8 kW. Hybrid inverters can be used with either lithium-ion batteries or lead-acid batteries with a maximum charge and discharge current of 190 A.
“Solis has launched the new S6 Advanced Power Hybrid Inverter, which combines solar generator and battery connectivity to free South Africa’s power-hungry households and businesses from the unpredictability of daily power outages,” said James Frank, Solis Country Manager for South Africa. “Especially the management of shaving peaks in both self-use and generator mode allows users to prioritize reserve power for their most critical loads more flexibly and cost-effectively.”
The inverters are available in five versions with outputs of 3 kW, 3.6 kW, 5 kW, 6 kW and 8 kW. The dimensions of the first four versions are 440 mm x 598 mm x 205 mm and the weight is 24 kg. The dimensions of the 8 kW inverter are 437 mm x 675 mm x 215 mm and the weight is 27 kg.
The efficiency of new products is 97.5% and the European efficiency is 96.2%. They have two maximum power point tracking (MPPT) with an MPPT voltage range of 90 V to 500 V in the 3 kW and 3.6 kW versions and up to 520 V in the more powerful versions.
The maximum supply voltage is 600 V and the recommended maximum PV power varies between 4.8 kW and 12.8 kW. According to Solis, the inverters support both single-phase and three-phase connections, with a maximum power of 36 kW in parallel for smaller devices and up to 48 kW for 8 kW inverters. The S6 series is compatible with lithium-ion batteries or lead-acid batteries with a battery voltage of 40V to 60V.
The maximum charge and discharge current of the 8 kW device is 190 A, which allows the generators to be connected with several input methods and automatic on/off control.
“This flexibility prevents over-provisioning of unnecessarily high capacity inverters, solar arrays, generators and batteries, resulting in significant asset and operating cost savings compared to our competitors,” said Frank. “With an automatic UPS switching function and a 10-second, 200% overload capability, users can be assured of uninterrupted power supply during power outages, even for the most sensitive electronic equipment.”
The operating temperature range of the inverters is -40 C to 60 C and they are IP66 rated.
