Chinese inverter manufacturer Solis has launched a new series of three-phase low-voltage hybrid inverters, the S6-EH3P(8-15)K02-NV-YD-L range. The series includes inverters with AC output capacities of 8 kW, 10 kW, 12 kW, and 15 kW.
One key benefit of these low-voltage inverters is their compatibility with more cost-effective low-voltage batteries, which are becoming increasingly affordable due to declining manufacturing costs. According to a company spokesperson, this allows for lower upfront costs for installations, making solar energy more accessible to both homeowners and businesses.
The inverters feature a maximum input current of 20A, designed to support all high-power photovoltaic (PV) modules, regardless of the brand. The battery’s DC side can handle a maximum charge and discharge current of up to 290 A, enabling greater energy storage from PV systems.
The series supports PV DC inputs ranging from 12.8 kW to 24 kW, depending on the model. The maximum input current varies between 20 A and 40 A, while the maximum short circuit current is rated at 30 A or 50 A. Output currents range from 12.2 A to 22.8 A, with an efficiency of 97.6%.
The inverters are capable of operating in tandem to form a microgrid and include dual backup ports for intelligent load control. The system also features a 200% overload capacity for up to ten seconds, providing robust performance during peak demands.
Each inverter measures 43 cm x 66 cm x 30.5 cm, weighs 42 kg, and operates within a temperature range of -40°C to 60°C. The inverters are designed for use at altitudes of up to 4,000 meters and rely on fan cooling for thermal management. Additionally, the company highlighted the ease of balancing low-voltage batteries, which enhances their lifespan and ensures efficient performance without the risk of overcharging or undercharging.
